Vol 1 Chapter 3

Kizuna awoke after being unable to sleep well.

His body was heavy.

After all, yesterday was completely wretched for him.

“My fatigue, is still not going away……yy-!?”

“To wake up even later than this me, there is a degree even if you want to slack off.”

About 30 cm in front of his eyes, there were red eyes staring at him.

It was Chidorigafuchi Aine in her uniform appearance, she was lying on her belly above the futon.

“Yo, you! Why are you here!?”

“I have come for yobai.” (TN: stealing into a girl’s bedroom at night to make love)

“This is morning!”

“Isn’t yobai called as an early-morning attack?”

“No, it feels like that, but it’s different somehow!”

When Aine tilted her head, her silver hair smoothly flowed down on his chest. A nice smell gently drifted in the air. Even through the futon, he could feel the b.r.e.a.s.t.s of Aine which were full with the sense of weight.

Putting aside the yobai, she might be really serious in her early-morning attack statement. After all, yesterday her half-naked body was touched around, her naked breast was rubbed, and the whole particulars of it were screened in front of the whole student body. Looking from her point of view, she would surely feel embarra.s.sed.

“Then how are you feeling I wonder? Feel excited?”

‘――Ha?’

“So you cannot even say any word. I wonder if far from being excited, you are now already becoming an animal in mating season instead?”

“I’m not! Rather, a human won’t have anything like that!”

Just what was going on with this girl? Wasn’t she coming here for her retaliation on him?

“How strange. According to my material, an erotic event should occur when a girl comes to wake up a boy in the morning though.”

“What kind of material is that! It’s fine already, just move away. I’m already awake.”

Looking at the clock beside the pillow, the time was already 8 o’clock. Although the dormitory and the high school building were near, he wanted to go to school with some time left because this was his first day.

This place was Ataraxia’s student dormitory.

After the commotion yesterday, he was forcefully taken away somewhere. He didn’t bring a single thing from his residence in Tokyo float, but this dormitory had already provided the full set of furniture for the resident, so he was not inconvenienced at all. Home appliances like television and audio were completely provided here that he had no complaint about it, and the furniture and equipment were so splendid that he wanted to doubt whether this place was a high cla.s.s hotel.

Most of all, not all the rooms were splendid like this. Only members of Amaterasu who possessed Heart Hybrid Gear were treated specially like this, so he heard.

When Aine stood up from the bed, she ripped off the futon from Kizuna.

“Wa-! Don’t pull it off so suddenly!”

Ignoring Kizuna’s words, Aine was glaring at Kizuna with a grim look.

“Then should we begin?”

Hearing those words, he felt a pressure that was nearly a killing intent.

‘Do, don’t tell me…… as expected, she is coming for me?’

“Wha, what is it?”

“Of course, it’s for activity of love. With the flow until now, the love between you and me should be heated up enough correct?”

Aine took off her jacket and threw it away.

“Nothing is heating up for even a millimeter. Rather I’m shrinking here from terror.”

“You are really noisy about every little thing. It’s fine already so let’s just do it quickly.”

Aine grasped the collar of Kizuna’s sleepwear and took it off with a force that almost tore off the front b.u.t.ton.

Kizuna’s collarbone until his stomach became exposed.

“Uwaaaaaa…… a……?”

Aine froze while still grasping the sleepwear. She was staring fixedly at Kizuna’s upper body without averting her eyes. Her cheeks were also slightly colored red.

“……No, now! Quickly do Heart Hybrid with me!”

“Wa, wait! Just wait a second, why are you rus.h.i.+ng this much!”

At that time, the door was knocked.

“Hida-kun? If you don’t wake up soon, you will be late to the homeroom you know?”

That voice was, Himekawa Hayuru.

It would be terrible if she found him in this kind of situation.

“It was inexcusable for me to be angry yesterday with you without giving you the chance to explain yourself. Perhaps you also have your own circ.u.mstances…… excuse me, are you there?”

‘Uwaaaa! What, what to do!? But, there is nothing that I can do!’

He could do nothing but pray so that Himekawa would leave just like that!

“By any chance, if you are still sleeping then I have to wake you up…… then excuse me.”

Just limited to this situation he was being really troubled from that kind heart!

“Ara? You are he…… re, are……”

Himekawa’s eyes could see nothing except Kizuna whose upper body was naked and Aine whose uniform was disordered hugging each other on top of the bed. Moreover, Aine was straddling Kizuna’s waist.

Three seconds later, Himekawa reached her own conclusion.

“Illicit s.e.xual relations.h.i.+p…… ho, how shameless…… in this sacred dormitory, to, to-…… what an, indecent act! Yo, you are trying to rape Aine-san again like this! You can’t be forgiven anymore!”

“You’re wrong! No matter how you see it, I’m the one being pinned down here! I’m the one getting attacked!”

“Haa? You are still saying idiotic things like that! Are you thinking that such unsightly excuse can possibly be believed? A girl attacking a boy, how nonsensical.”

No, that was the truth though!

“Hayuru. It’s hard to say this but, what this s.e.xual offender is saying is true.”

“……Ha?”

“The one attacking, is this me.”

“That, that’s……”

With a face that expressed how she couldn’t believe it, Himekawa staggered on the spot.

“There is the need to perform Hybrid Heart even for a second faster, so this can’t be helped.”

Aine puffed up her chest proudly.

“No…… just why are you looking that haughty?”

“But, I wonder if this is what is called as a female carnivore? It’s obvious but I love meat you know. Especially the specialty product of Mie float, the Matsusaka beef, it’s really delicious. Kanagawa float’s Hayama beef is also hard to discard. I wonder what kind of meat Hayuru likes?”

“Thi…… this is, my limit already. The, the both of you……”

Himekawa’s shoulders were shaking in fury.

“I’ll punish you! Neros!!”

Red light filled the room, a red armor was fixed on Himekawa’s body.

‘Thi, this girl-! She is putting on her Heart Hybrid Gear!’

“Le, let’s calm down and have a talk! It should be strictly prohibited to have a personal with by putting on our gear!”

“No need to worry. After all this is an official duty as a public morals committee member!”

Himekawa drew out the sword hanging on her hips and slashed at him.

“You’re forcing your own rule too much!”

“Zeros.”

Aine too materialized her gear and stood in the way of Neros.

However there shouldn’t be any way to block the sword of Neros that was swung down.

Something like catching a blade with bare hands was an impossible story from the beginning. The empty handed Zeros could only get cut down like that――was how it was supposed to be.

“Kuh-……!”

However, the sword was stopped.

Zeros moved with amazing speed and stopped not the sword, but restrained the hand that was holding the handle of the sword.

“……Impudent act.”

“In this range, you are no match for Zeros.”

“Is that so? Such thing won’t be understood unless we test it.”

Himekawa showed a belligerent smile.

“You, you girls! Don’t fight in someone’s room! The scale of your fight is ――”

After that, Kizuna’s room met with devastating damage after a defense and offense of less than ten seconds.

‘……What a terrible experience right from the morning.’

Kizuna exited the dormitory and headed towards the school building.

It seemed that his room couldn’t be used for a while. Fortunately, there was still an empty room and he could exchange his room.

The two perpetrators were severely reprimanded by the dormitory head. Due to that they might arrive late to school.

Well, they reaped what they sowed.

He was thinking of going by using public transportation, but he would still make it in time even by walking.

He went by walking while viewing the townscape at the same time.

The transportation in this Ataraxia was mainly underground trains, thinking from how the enemy might attack. The inside of the underground train could also be used as a shelter in emergency time.

Next was the unmanned electronic automobile, but it was applied as a taxi. It was convenient how it could be used to go everywhere no matter the route.

While thinking of such things, he was walking through the roads that were cleanly maintained.

It seemed that, somehow, around this area was not affected by the battle yesterday.

Both sides of the road were planted with trees, giving tranquility to the people walking down the road. Pa.s.sing through that road were many students heading to the school.

Kizuna planned to walk mixing with those students, but he noticed something strange.

There was no one coming closer around Kizuna.

Everyone was getting out of the way from Kizuna’s vicinity, they were whispering gossip from afar.

‘Aah…… I see. So this is also, reaping what I sowed…… is it?’

He could listen to the whispering voices.

“That’s Eros.”

“Eros you know.”

“The Eros.”

‘Aah-, geez! Ero, ero, how noisy!’

He made his steps faster as if to run away toward the high school building.

When he pa.s.sed through the gates, he could immediately see the school building standing tall. Its steel frame was exposed, the wall was made using composite materials, it looked rustic but it was a cool building.

He entered the building from the entrance.

But everywhere he went he was met with curious stares and malicious gossip. It was wholly uncomfortable.

‘Let’s not pay it any mind and head to the cla.s.sroom. Though, this situation will also happen in the cla.s.s too.’

“Err…… the second year first group if I remember right.”

The high school part was largely divided into battle department and research department. He was in battle department so this first group must be a battle department…… was how it should be.

He confirmed the plate of the cla.s.sroom and opened the door.

The attention was gathered at him all at once, but the students immediately averted their gazes.

But among them there was only one person raising her hand smiling at him, a female student.

“Haai, Kizuna. I wonder what kind of business you have in my cla.s.s?”

It was Yurisia Farandol.

Blonde haired and blue eyes, her uniform was filled to bursting with her b.r.e.a.s.t.s and waist. As usual, she had a showy appearance. She was by no means gaudy, she was like a high grade precious stone where he could feel her fine quality and elegance.

Also there were five, six female students that seemed to have fine upbringing surrounding around Yurisia.

“Wai-, Yurisia-sama! You must not call out to that man.”

“That’s right! Exchanging word with someone like that will dirty Yurisia-sama!”

The hanger-on group were glaring at Kizuna with eyes filled with hostility.

‘How amazing. When all’s said and done, she is like the queen of the high school.’

“Now, now, everyone. He is a transfer student. It’s no good to not be kind to him♪”

“My, how kind you are, Yurisia-sama.”

“As expected from the queen of Ataraxia!”

Somehow, rather than a clique it looked more like a religion.

“Wait a second the lecher over there! Yurisia-sama is the ace of the American army and the flower of high society, she is a lady of American celebrity. It’s a dream that cannot possibly be granted for someone like you to exchange words with her. Don’t come closer to her in a radius of 5 meters from now on!”

Now that she mentioned it, he had watched the news before that America dispatched their Heart Hybrid Gear to j.a.pan. If he remembered right it was something about advantageous deployment for the strategy in the Pacific Ocean as allied nations, or returning the favor for j.a.pan’s provision of Heart Hybrid Gear technology to America, that kind of content.

So that pilot in the news was this Yurisia Farandol.

“Right, right, how awe-inspiring that is. I understood already.”

“What’s with that att.i.tude of yours!”

At the other side of the angry hangers-on, Yurisia was looking at Kizuna and sent him a wink.

That act and expression of hers made his heart jump for a second unconsciously.

“Oka―y, everyone take your seat. The homeroom is starting now―”

A female teacher wearing a red jersey entered the room.

Her hair was carelessly tied behind her and tiresome aura was coming out from her whole body. He guessed that her age was around the later half of the twenties. Even though she was a beauty when he looked carefully, there was the feeling that it was ruined by none other than herself.

“Aa― Hida-kun. You neglected going to the staff room and came here haven’t you―”

“Ah…… is that so, I’m sorr――”

“Right, it’s fine so don’t let it bother you. I am Sakasaki Saki. Your homeroom teacher.”

With a sleepy gaze, she waved her hand tiresomely.

“This is a good timing, oka―y, come to the front.”

Obeying what Sakasaki-sensei told him, he stood at the podium in front of the cla.s.s and looked over the cla.s.s.

There he felt an uncomfortable feeling.

“Err, sensei…… there are a lot of girls here isn’t it?”

A lot, that expression was not an accurate one. The correct one was that, there was n.o.body but girls here.

“Hm? Because this is an all-girl cla.s.s after all.”

‘Eh?’

“Look, you students are boys and girls in that age right? Especially the stimulation of pilot suits are strong see―. So that there will be no mistakes occurring, the cla.s.ses and training are divided between the boys and girls. If I have to make a reference, this first group is the top of the battle department female group. This cla.s.s is called Flourish cla.s.s.”

He didn’t know at all that was how the cla.s.s was divided.

“Then, it’s really bad for me to be here. I have to quickly go to the boy cla.s.s.”

Sakasaki-sensei firmly took hold of the wrist of Kizuna who was trying to get out of the cla.s.s.

“Aa―, it’s fine, it’s fine, your place is right here.”

Haa?

“Then, you all know him but I’ll give an introduction one more time. This is Hida Kizuna-kun who newly enters this cla.s.s. Everyone, get along well with him. In that kind of meaning.”

“Teacher, please don’t say anything like ‘in that kind of meaning’.”

The door of the cla.s.s was opened loudly and Himekawa made her entrance. Behind her there was also Aine.

“Oh, Himekawa and Chidorigafuchi. It’s rare for you two to wake up late.”

Himekawa walked until the teacher podium with loud steps before she pointed at Kizuna.

“I didn’t wake up late! It’s the fault of that man over there that I came this late! Rather than that, what is the meaning of a boy joining the girl cla.s.s!? Such thing cannot be permitted!”

“Yep. Sensei also thinks so, but this is actually permitted.”

“Please explain!”

Only in this kind of time Kizuna and Himekawa were in the same opinion.

“Th, that’s right. Besides, sensei too already said it yourself just now. That we all are boys and girls in that age and so this division is so that no mistakes will happen.”

“Aah, rather you need to do that mistake. With all you got.”

“What the h.e.l.llll, is thatttt!”

“Because this is the strategy so it can’t be helped. Everyone too, do your best in various things with Hida-kun, okay? Errr―, yesterday the seats had been rearranged to make place for your sitting. Over there, near the window.”

The seat the teacher pointed at was located behind Himekawa, his right was Aine, and in front of Yurisia, then at the left was a window where he could always dive out for the next world, that location was perfectly surrounded by enemies from all sides, it was truly a land of death where he was isolated and helpless.

No, no matter where he was sitting, there was no safe area for him in this cla.s.s. The cold gazes of all the cla.s.s members were mercilessly shaving off his will power.

When the morning cla.s.s was over, Kizuna’s will power was already endlessly close to zero.

“Haa…… I’m tired.”

Afternoon break. Kizuna exited the school building as if running away. He couldn’t bear the gazes of his cla.s.smates that were filled with disgust. The atmosphere made him feel like he was going to choke, that when he went outside he breathed in relief.

“I wonder what I should do about lunch…… maybe it would be better if I asked about the school cafeteria.”

However, if he took a step outside the school, there would be a lot of food stores outside.

When he peeked outside, there were a lot of students having fun talking while having their meals.

If it was like this, then even without a school cafeteria there would be no problem at all.

After hesitating, in the end he entered a fast food store that was safe.

However, the moment Kizuna entered the store, the bustling atmosphere inside froze.

‘――Eh? Wh, what?’

“O, oi. That guy, that’s Eros.”

“Don’t look, it seems that you will get pregnant if your eyes meet his you know?”

“I heard that the second year Chidorigafuchi and Himekawa had already become his prey.”

“Is the implementation for the a.s.sa.s.sination plan not finished yet?”

“Shh, about that talk……”

‘Oi oi oi! There is a dangerous talk that’s not a laughing matter mixed there!’

Kizuna exited the fast food store to escape, but on the outside, gazes from the girls as if they were looking at something filthy were directed at him while gazes filled with envy and grudge were glared at him from the boys.

‘Aah…… can I keep living here like this?’

“Hida-kun.”

Kizuna was surprised from hearing a voice calling his name.

So there was a person who would talk to him in this Ataraxia.

However, he comprehended it after seeing the owner of the voice.

“Chidorigafuchi huh…… what business do you have with me?”

“What are you going to do for lunch?”

“Uu……”

He couldn’t answer. Honestly, he didn’t have anymore prospect.

“Is that so? If so then come with me. I’ll bless you with a meal.”

“Are you treating me, or are you saying that I’ll be the one treating……”

However, there was n.o.body else that would eat together with him. In the first place, it didn’t seem that he would be able to obtain any lunch. As far as he was concerned, he had no other option.

“……Got it. I’ll accept your gift. Then, where to?”

“Follow me.”

He was led into a forest where there was no human presence.

When they pa.s.sed through out of the forest, there was a terrace that faced the sea with chair and table put there.

Or perhaps it should be said, that this place was right near the spot where he met Chidorigafuchi for the first time.

Kizuna nervously sat side-by-side with Aine.

When Aine opened the wrapping that she was holding, a bento box appeared from inside.

“Here, eat up.”

Inside the box were crammed with beautiful sandwiches.

“Oo-! Don’t tell me this is handmade?”

“That’s right. For you to be able to eat the handmade bento by this me, you are truly the happiest person in the world.”

He didn’t know about that, but, anyway, this was a lunch that he had prepared to give up just now. Let’s just eat it gratefully.

“Itadakima―su.” (TN: Itadakimasu, a phrase j.a.panese people say before eating.)

Tuna sandwich, egg sandwich, he ate them one after another.

“Oo-, it’s really delicious! But, this……”

“Is there something?”

“No, it’s like…… the taste is really similar with the sandwiches sold in the convenience store.”

“Of course it’s like that. It’s something I bought from the convenience store.”

“Then this is not handmade!”

“I cut them into half and put them into the bento box.”

“What kind of explanation is that! If that’s true, then even heating instant curry counts as handmade, putting hot water inside cup ramen also counts as handmade cooking!?”

“Then I’ll ask you this, where does the definition of handmade cooking begin and where does it end?”

‘Eh-?’

“For example, if you buy bread and tuna can in a convenience store, then can you call it handmade cooking if you jammed the tuna between the bread I wonder? I cannot feel any fundamental difference from there, though.”

“No, well, certainly that might be true but……”

“If you talk about handmade cooking in that kind of meaning, then as expected you will need to grow the wheat and catch the tuna fish from the place where they set out, you have to do everything from the start. However, if Hida-kun tells me to do that no matter what, then I think I’ll submit permission to leave school and board a tuna fis.h.i.+ng fish.”

“I’m sorry! Chidorigafuchi’s handmade lunch is delicious!”

“It’s fine if you understand.”

What a tiresome woman, this girl.

“Right right, also there is one more thing, there is something I want you to eat.”

“Hm? What. Something like a desert?”

Aine stood up and stood in front of Kizuna.

And then, she pinched her skirt and slowly lifted it up.

“Wha-!?”

“To call this a desert, I’ll take off my hat towards the extent of your sleaziness.”

“Just who means that! It’s fine already, just put back down your skirt! It’s totally visible from here!”

“……You’ve seen it?”

“N, no…… just barely, only almost, I didn’t see it though.”

However, the thighs that could be seen from the gap between the skirt and the over-knee-socks were dazzling. And then, if the skirt was raised one more millimeter, the panty would be visible.

In the case of this morning she was also like this, but, did this girl not have this thing called shame?

When he stared fixedly at Aine’s face, her cheeks seemingly had a reddish tinge.

“Look here…… by any chance, are you actually embarra.s.sed?”

“There is no way that’s true. Look at how calm I am.”

When he saw her wrist, the finger tips that were pinching the skirt were shaking.

“How is it? It seems that by doing an act that cannot be done inside the school, the feeling of immorality gives rise to excitement.”

Kizuna gulped his saliva.

“If you want to see, it’s fine to flip it over you know.”

Her voice seemed calm, but her expression looked anxious somehow.

This girl, actually she was unreasonably forcing herself wasn’t she?

……Should he test it?

Kizuna slowly reached out his hand to her skirt.

Aine’s thighs quivered s.h.i.+veringly.

“As I thought, you are really forcing yourself right?”

“……I wonder what are you babbling about, you animal. There is no way that this me will falter from just this much.”

“But, you are shaking you know?”

“This is warrior’s excitement from the antic.i.p.ation of obtaining the [Corruption Armament] from now on. I’m really happy I cannot bear it.”

――Corruption armament?

“What is that…… this thing called [Corruption Armament]?”

“It’s fine already, just strip this off. I don’t mind at all so…… just this much.”

Aine’s cheeks reddened and she averted her eyes.

“I, if you say until that much then……”

After Kizuna pinched the skirt’s hem, he slowly lifted it up.

He could almost see the area where her long and slender two legs were connected into one.

And then, finally that summit became visible.

At the other side, he could peek at her a.s.s right from the front.

This was, a girl’s panty……?

“Err, Chidorigafuchi-san.”

“What is it?”

“……This is a pilot suit isn’t it?”

“Yes. I don’t know when I will need to scramble out after all. Naturally I’m wearing it under my uniform.”

Honestly, this was also erotic so it was completely okay! But, for some reason he felt cheated!

“No doubt you are aroused right? Now, with this, all the preparations are complete. Quickly make the Corruption Armament――”

“Err……”

There was a voice that was not Kizuna’s or Aine’s.

Without them realizing it, there was a girl standing nearby. She was a middle school student but her height was short like an elementary student.

‘Craaaaaaaaaaaaaap!’

Just what kind of scene he showed to this innocent girl!

‘Like this ain’t I completely a pervert! A hundred percent molester!’

That girl, with her pet.i.te body and beautiful blonde hair completely looked like a westerner. Her large eyes opened wide in perfect circle looking at him.

Perhaps he had already planted a trauma inside a girl this cute that she wouldn’t be able to forget for her whole life.

‘However, if that happened then I would continue to live inside that girl forever…… This is not the time to think something stupid! I’ve got to think of an emergency countermeasure now!’

“By the way Hida-kun. I wonder if you can release you hand from my skirt soon? It’s a little bad to show this in front of an undercla.s.sman I think.”

‘GYAAAAA, I’m still flipping over her skirttt!’

Kizuna separated his hand in panic and desperately began to make an excuse.

“Y-, you! This is not how it looks like, by no means I’m doing something that I need to feel guilty about!”

That girl tilted her head a little with a puzzled face.

“Yes. This is a mission right desu? I thought that this might be the strategy that commander talked about yesterday desu, but…… am I mistaken desu?”

‘Eh…… what?’

“Excuse me for my lateness desu. I am called Sylvia Silvercut. I was told by the commander to bring Hida-senpai to her desu.”

She smiled in a friendly manner and bowed cutely.

He left Chidorigafuchi on that spot and was led away by Sylvia out to the street. There, a large limousine was stopping at the roadside.

The door was opened by Sylvia and he boarded the car as he was told.

“Kizuna, sorry to be sudden like this.”

“Nee-chan!?”

After Sylvia also got in, the car started to move without sound.

Kizuna stared at his sister sitting in front of him in a glare.

“There is a lot of things I want to ask Nee-chan.”

“What a coincidence. There is also a lot that I want to talk with you. But, I think it’s fine to do that after we arrive, first let’s finish the small ch.o.r.es.”

From her bosom, Reiri took out an appliance that looked like a small communication device.

“I’m giving this to you.”

At a glance, the thing looked like a smart phone’s show model.

He recognized this thing…… now that he thought back, the students here were all using this.

“That also doubles as a student’s identification card, a communication device exclusive for Ataraxia. From all sorts of contact methods, schedule, attendance and grades, health condition and the likes, everything is managed by that device.”

When Kizuna touched the screen, an interface he had never seen before was booted up.

“Heee…… this is cool.”

“Yours is specially made, there is an Amaterasu icon there correct? Try to start up that application.”

Kizuna did as he was told and tapped Amaterasu’s mark that was designed as wings and heart mark. Thereupon, the names of Aine and the others, and all sorts of parameters were displayed.

“What is this? From height and weight…… even the three sizes are shown here!? Isn’t this personal information?”

“That’s why no one but you can see it.”

‘Aah, is that so…… no, isn’t that also no good?’

“From basic specs until their vital sign and current location, all of those are being monitored in real time. There is an item named Hybrid Count there right?”

There was a graph signed with a heart mark there.

“That’s the remaining energy of the Heart Hybrid Gear. Do Heart Hybrid before the gauge enters the yellow zone.”

Yellow zone was starting from 25%, and under 10% was the red zone.

“When the energy remaining is less than 5%, it will become hard to even maintain the Heart Hybrid Gear. Pay careful attention so that the energy won’t get lower than that. Understand?”

“Just wait a second! About that story, since yesterday it’s just full of things that I don’t get. Just what in the world is happening, explain it to me so I can understand a little bit more!”

Reiri took out a juice from the car’s mini-bar, then she offered it to Kizuna and Sylvia.

“The detailed explanation will be after we arrive.”

Kizuna felt a little dissatisfied having the explanation delayed, but he obediently consented.

He believed that now Reiri had said that, she would surely give him an explanation later. Reiri had never failed to keep her promise to Kizuna.

“Rather than that, I’ll introduce Sylvia to you once more. She is a transfer student from Britain, Sylvia Silvercut.”

“Britain?”

Research and development of Heart Hybrid Gear was also conducted outside j.a.pan, but most of them came from the technology gifted by Ataraxia. And so promising human resources from all over the world came to this Ataraxia.

Although, that was the story before the Second Another Universe Conflict occurred.

He guessed that Silvia too arrived in this Ataraxia before that time.

“She is a first year of middle school, but she is an extremely excellent personnel. From today on, she will work as your subordinate.”

“Subordinate!?”

“Please take care of me, Captain!”

“Captain!?”

“Yes! Sylvia is Kizuna-senpai’s subordinate. I was a.s.signed with formal appointment to this position. That’s why, Kizuna-senpai is Sylvia’s captain desu.”

“Ne, Nee-chan, a subordinate for me, what is the meaning of this?”

“I don’t mind whether you make her help you for your daily life or whatever. It’s fine for you to order her for any kind of business. She is your first subordinate. Be affectionate to her.”

Be affectionate!?

“No matter how you look at it, isn’t that a crime!?”

“……What are you thinking inside your brain?”

‘Ah, so it’s not in that kind of meaning…… s.h.i.+t, it’s like I got completely brainwashed unwittingly.’

“Well, this girl is also one of the candidates. If it looks like she has good prospect, I won’t stop you from that.”

“No, stop me! As an elder sister, as a person in position of responsibility!”

“Also, I’ll make Sylvia report whether you make progress in your relation with those la.s.ses or not.”

‘So that was your true objective making Sylvia my subordinate! Isn’t that just a nice way of saying that she is my overseer!

“Err―, are you fine with that? Having me as your captain?”

“Yes! Sylvia is the number one member of Kizuna squad desu. It’s an honor desu!”

She was looking up at him with bright eyes.

Kizuna was unable to do anything except powerlessly smile towards that pure eyes.

“As poor as I am, Sylvia too will do her best! I will become the strength of Captain, I want to make this strategy a success desu!”

“At first it’s only Sylvia, but I expect you to someday become a captain that leads the Heart Hybrid Gear force, Amaterasu.”

“……That’s a really unthinkable long distance for me.”

After the car drove for ten minutes, they arrived at the destination.

“Eh…… this place is”

When he got off the electric automobile that was automatically driven, he was in front of a building that he recognized.

“Sylvia will explain desu! This is the Heart Hybrid Gear laboratory desu. It’s called Nayuta Lab. But, why is this place called Nayuta Lab?”

“That’s……”

That was because his mother’s name was Hida Nayuta.

Sylvia returned back using the car after that and Reiri and Kizuna entered the lab.

They walked a corridor that he was familiar with.

When he was a child, he had come many times to this lab. He felt strange freshness and nostalgia.

“But, is this corridor this narrow? The ceiling is also low, even the entrance should be bigger.”

Kizuna spoke while observing the pure white corridor.

“You are the one that had grown bigger.”

Reiri who was walking ahead gave a calm retort.

‘There’s that.’

Before long, they arrived in front of the room that his mother once used as her research room.

Nervousness ran in Kizuna’s heart.

“This is Reiri. I’m entering.”

It was an excessively s.p.a.cious and pure white room.

At the center, there was a console that looked like a c.o.c.kpit. A lot of floating windows were surrounding that console.

In front of that console, a girl in a white research coat was sitting. She was busily operating the keyboard and touch panel.

“This girl is the supervisor of this lab, the person working in charge of Ataraxia’s technology, s.h.i.+kina Kei.”

When she was introduced, she turned to Kizuna with a glance.

She had a pet.i.te body so he didn’t know but, it seemed that she was the same age as Reiri. Her hair was in a bob cut style and put in place by several pins, perhaps it was so that the hair wouldn’t become a hindrance in work.

Her cold eyes behind her gla.s.ses were observing Kizuna intently.

She didn’t say anything and turned her back to him before running her fingers through the console’s keyboard.

A floating window popped up in front of Kizuna.

{How do you do. I am s.h.i.+kina Kei. A close friend of your big sister since our time as students. You can call me Kei. Nice to meet you, Hida Kizuna.}

“……”

“She is a fellow that is poor in communications with other people. Well, don’t mind it.”

“Y, yes. Then…… why am I here?”

“It’s for adjusting your Heart Hybrid Gear.”

Kizuna’s heart jumped sharply in his chest.

‘Don’t tell me, Kaa-san will?’

“I’ll say this first, but if it’s mother then she isn’t here.”

“Eh-? Is, is that so……”

He felt complicated, as if he was relieved and disappointed.

“That person right now is missing.”

‘――Ha!?’

“Missing you say…… how?”

“She disappeared. A certain day when we noticed, she was already nowhere.”

“Disappeared? Just where in the world did she go then?”

“Because we don’t know that we say she disappeared.”

“But, with the world right now, just to where can she go? She cannot move anywhere except to the other floats in this Megafloat j.a.pan, the coming and going of people is also being managed. She should be discovered immediately right?”

Kei was typing with a speed that even the eye couldn’t follow.

{She couldn’t be found. No matter what we did anywhere. Looking just from the investigation result, Professor Nayuta right now is not in Megafloat j.a.pan anymore.}

“That’s…… was she moving when we came into contact with other country’s float?”

{That’s one of the possibilities. But, if the professor felt like it, the security of all float will be meaningless. Searching for her is a pointless waste of time.}

Just what in the world happened?

He thought that even a mother like that was advancing her research for the sake of the world and mankind…… despite that, she vanished in this essential time, there was a degree even for being irresponsible.

“Kaa-san…… just what in the world is she thinking?”

“Who knows. That person’s thinking cannot be understood by us. I don’t even want to understand anyway.”

Reiri spitted those words out.

{But, last month an unregistered mail was sent to us. The content was the data regarding the ability of Hida Kizuna, about your Eros. Most likely it was something written by Professor Nayuta.}

“Eh? Then……”

{Of course, we tracked the mail but it was pointless. It’s just, there is only one person in the whole world that knows of the detailed data of Heart Hybrid Gear. Only Professor Hida Nayuta.}

“Kei a.n.a.lyzed that data, it was three days ago when the meaning and conclusion of the data could be derived. And then I called you here.”

When Kei operated the console, windows were started up around Kizuna, several formulas and graphs that he couldn’t comprehend were displayed.

{This is a ground-breaking discovery. It is explaining about the special ability that is possible only by Hida Kizuna’s Eros.}

“My gear?”

“Right. And then, there is also the answer about just why the performance of your Heart Hybrid Gear is low there.”

Kizuna’s heart felt a sharp pain.

Without a single change in expression, Kei continued to type in the keyboard.

{The performance of Hida Kizuna’s Heart Hybrid Gear is low because he has no apt.i.tude, that explanation is not accurate. The correct answer is, because you are a male that the trait is different.}

Because he was a male?

{Only after Heart Hybrid Gear was installed into a female that it would display its original performance. The reason was unknown, but from the experiment result, it had to be recognized as fact.}

Reiri nodded in affirmation.

“In reality, we are sorting out the candidates who have high apt.i.tude for Heart Hybrid Gear and also excellent skill, but the chosen personnel are all female students.”

So that was it. Because of that, the ones who possessed Heart Hybrid Gear, Chidorigafuchi, Himekawa, and Yurisia, all of them were girls.

{However, we understand that this is the difference of trait between male and female. In exchange for male’s low battle ability, their consumption rate of Hybrid Count is little.}

“Eh! Isn’t that really advantageous――”

“Their Life Saver is long lasting I guess. However, only having high stamina won’t defeat the enemy.”

Kizuna was jumping in joy, but his shoulders immediately dropped in dejection.

{But, your Heart Hybrid Gear [Eros] has a special ability that is only available when it is installed in a male.}

“That’s, the special ability, that was written in Kaa-san’s mail?”

{Correct. That is the Heart Hybrid phenomenon. We called it [Union Remodelling].}

Kizuna recalled yesterday’s occurrence.

“That’s the thing that I did with Chidorigafuchi yesterday right?”

“Right. I also explained it in the general meeting yesterday.”

If he remembered right, with two people, man and female possessing Heart Hybrid Gear, their body and heart into one, sharing their affection and pleasure…… something like that.

{With the proffesor’s data as the basis, we tried various simulations. The result, we obtained the conclusion that this was something that only Hida Kizuna’s Eros could do. For that reason, we called Hida Kizuna from Tokyo float until Ataraxia in a great rush.}

So that’s it…… he finally felt like he could comprehend the situation.

{There is an unlimited possibility in this technology. It’s not limited to simply replenis.h.i.+ng energy, it also included the possibility of realizing power up of the Heart Hybrid Gear. An addition of new weapon that is not there until now. We are also having expectations for that.}

Now that she mentioned that…… before this, Chidorigafuchi was also talking about something strange.

“Is there any relation about that with this thing called Corruption Armament?”

Kei’s hands stopped. She was staring intently at Kizuna.

However, he couldn’t read Kei’s thinking at all from her face. He felt like she was not looking at him, but perhaps to something that was behind him.

Kei’s fingers moved while she was still facing him.

{Where did you hear that story from?}

“Err, just now from Chidorigafuchi……”

{I see, I understand. Exactly, they are connected. Until the end, Heart Hybrid is nothing more than energy replenishment for Heart Hybrid Gear. However, when the heart and body become one even far deeper than that, the two’s energy resonance will reach the limit and one can obtain a new weapon, the [Corruption Armament].}

“What kind of weapon is that?”

{Unknown. But from the research result, we can only confirm that such a weapon exists. But no one has seen it before, so it cannot be verified.}

“And Aine wanted that?”

“Yeah. At that time, I didn’t get it all just what she was talking about though. In short, she wanted to do erotic things and obtain a new weapon…… something like that.”

Reiri crossed her hands and smiled.

“Isn’t that fine? Give her that present.”

Kizuna’s face scowled.

“But, I said this yesterday at the auditorium too, I think that it’s important to consider each other’s feeling in this. Even if Nee-chan suddenly told me to do that kind of things with a girl that I just met for the first time, that’s obviously impossible isn’t it?”

“Is that so? I think that this is a happy situation for a man.”

“We, well, perhaps that’s so but….. that’s not it! Even though I look like this, I have reasoning and common sense! Hearing an absurd story like that, you think I can just suddenly say ‘Oh, okay’! Just what kind of harem manga this is!”

“It’s fine like this. I’ve made all kinds of preparations.”

{Not touching the feast before one’s eyes is a man’s shame.}

Even Kei was backing up Reiri.

“Bu, but even so, the feeling of the other party cannot be ignored I told you!”

“Then, everything will be fine if you just make those la.s.ses to like you.”

“No…… that’s impossible. If you use your common sense.”

“But, if you don’t do it then Heart Hybrid cannot be realized.”

Just why on earth were they this persistent?

Whatever the circ.u.mstances may be, their methods and ways were irrational, they were too forceful.

“About that, I have a stupid question here.”

“What?”

“When I was doing experiment as a child it was the same but, this energy of Heart Hybrid Gear will naturally recover to normal if you just leave it alone? Just why do I have to go that far to recover this energy?”

“That’s……”

Reiri was unusually hesitating to talk. Kei’s fingers were also tapping on the keyboard, but they were hovering in the air without going anywhere as if lost.

“……It takes too much time, waiting for the energy to recover naturally.”

{Just as we explained previously, the energy consumption rate of males are low. Furthermore, the experiment result of Hida Kizuna in the end is just from the initial stage experiment content. It cannot compare with the amount consumed in real battle. Also, the greater the obtained combat ability is, the compensation for that is also great. In this half year since the Second Another Universe Conflict, all of this has been proven.}

“I see…… similar with a car, if they travel a lot then it will take a lot of fuel to consume, if the performance is high then the fuel consumption is also bad, so it’s something like that.”

“Rather than that, let’s accomplish our objective today. The adjustment of Eros. If it goes well, it might be able to power up you know?”

“Eh!? Power up?”

Kizuna became excited.

“Right. It’s great that you saved Aine in the battle yesterday, but it’s a problem that you already fell from just that much ma.s.s. According to the data sent by mother last month, it seems that adjustment matching the wearer’s age is necessary. Though it’s different from Heart Hybrid, in the end this is just on the level of adjustment.”

“Even so at least the performance will go up a little!”

“That’s right.”

Reiri smiled gently.

Kei stood up from the console and moved close to Reiri. She pointed at a door and whispered something to Reiri in a small voice.

“Kizuna, if you go through that door, at the end of the path is the adjustment room. There is also a change of clothes there, so go ahead first and finish your change.”

“Roger!”

Kizuna got out of the room with joy welling up within him.

Silence visited the room where Reiri and Kei were left behind.

Worry was carved at Reiri’s forehead.

Kei faced Reiri and whispered in a voice that could be barely heard.

“Re-ri. Is it fine…… to not tell him the truth?”

“Yeah, this is something that someday I have to tell him…… I know that.”

Kei closed her eyes and nodded.

“I think it’s fine for Re-ri to follow your determination.”

“Sorry, Kei.”

Kei’s lips smiled a little.

――And then, the next day.

Kizuna was flying on top of the blue sea in excellent condition. The weather was also good, and he felt really good.

{How is it, your condition?}

Communication from Kei was displayed in a floating window as text.

“I’m in a really good condition here. Somehow, it’s like I’m reborn.”

The sea under his eyes was flowing behind very quickly. He was at a speed that he would  absolutely be unable to display if it was before.

He purposefully flew until he barely touched the sea surface, it was also fun dodging the waves. He got carried away and took a steep ascent and descent, he even tried somersaulting.

Today, Kizuna was given a mission to survey for resources. This mission was unrelated with other students of second year first group, this was a mission a.s.signed by Ataraxia, for Kizuna this became his first mission.

The content of the mission itself was simple.

Currently Ataraxia was sailing through the open sea of Indonesia.

Nearby there was an unpopulated island that was rich with resources, so he was told to go survey the island.

He thought that if it was not the specialist then such investigation couldn’t be performed, but it seemed that everything would be fine if he just operated the investigation device following the manual. The collected data would be transmitted to Ataraxia in intervals, and then combined with the sample they would bring back, the specialists would take time to investigate that.

A lot of the parts of Megafloat j.a.pan was made up from ocean resources and recycled resources. This was a simple mission, but it was important.

“Haai, Kizuna. You are in a good mood aren’t you.”

Yurisia took Kizuna’s side.

“Ah, Yurisia. Yesterday my gear got powered up a little. So I’m checking the movement a little.”

“Fufufu. You look like a kid that received a new toy, how cute♡”

‘U, certainly, I might have gotten too hyper here…… it’s a little embarra.s.sing.’

At that time, Yurisia received a private communication from Reiri.

“My, commander. Is there something wrong, for you to call me directly like this?”

{There is one thing you should be careful about. Yurisia, your remaining Hybrid Count is few. Right now you only have 20% left. Avoid combat at all costs.}

Yurisia looked over the blue sea.

“Aa―, it will be fine. After all this is really a safe place―”

Yurisia turned aside Reiri’s worry with a smile.

“Rather than for me, isn’t it better to worry more about the little brother I wonder? He is really in high spirits you know.”

Yurisia smiled amusedly.

‘――Really, it’s fine as long as he doesn’t get carried away and holds us back though.’

{Indeed, that guy getting merry like that is also one of my worries. In any case, I don’t think that this mission is dangerous, but there is nothing better than being careful. Don’t you dare let your guard down, okay?}

The communication from Reiri was cut off.

“Yurisia, who was that from?”

“No, it’s nothing. Well then, I’ll be going ahead.”

Leaving those words behind, Yurisia accelerated. Just in an instant she reached a tremendous speed.

“As expected from the ace of America’s army. No way I can catch up with that……”

“What are you saying? Something like someone you can catch up with, doesn’t exist anywhere here.”

Himekawa was coming closer to him while saying such harsh thing without hesitation.

“Ahahaha, well, now that you said that, that’s exactly right.”

Himekawa heaved a deep sigh and glared at Kizuna.

“Anyway, although this is a safe mission, carelessness is prohibited. Listen sincerely to what I say and refrain from arbitrary action. Especially, Aine-san!”

Looking at his other side, before he realized, Aine was also flying along his side.

“Right. I’m listening properly. Your question is what should be done so the b.r.e.a.s.t.s can become bigger, right?”

“No one is asking that kind of question!”

After shouting that with a red face, Himekawa flew away with amazing acceleration as if kicking away at the air.

“Uwa, incredible. So the one with fast speed is not just Yurisia huh―”

“I guess so. Her b.r.e.a.s.t.s are small, but Hayuru is j.a.pan’s ace you know? Even though her b.r.e.a.s.t.s are that small.”

“No…… that’s not related to breast size at all.”

He couldn’t feel anything but ill will from that already.

{I heard that! Please stop playing around-!}

Himekawa’s angry transmission shook his eardrums.

Himekawa too was pitiful.

Kizuna sympathized with Himekawa from the bottom of his heart.

Honestly, her b.r.e.a.s.t.s were not that small but, well…… if the comparison was with those two then it might really look small.

Kizuna took a look at the owner of the smaller one between those two.

The large b.r.e.a.s.t.s were shaking without pause from the vibration and wind pressure. It possessed an overwhelming presence.

“Ah, err, you saying that means Chidorigafuchi, you are j.a.pan’s number two then? Or else are you from another country?”

Her appearance was like a foreigner, but her name was in j.a.panese style. By any chance, perhaps she was an ace from somewhere in Europe.

“Don’t look down on me. I’m not such a small human that can be rated on that scale.”

“Eh? You mean……”

“I’m the earth’s ace.”

“E, earth!?”

‘Oi oi! That’s just too big!’

“That’s wrong, I’m mistaken just now. Yes, I’m the universe’s ace.”

“I got the feeling that I have seen something like that on the internet a long time ago!”

{You guys, leave the joking around behind.}

He could hear Reiri’s voice that was mixed with anger.

‘Dangerous, scaryyy.’

{The destination island will enter into view soon. When you arrived, begin investigation as planned.}

“Ro, roger!”

The unpopulated island that was their destination was actually a small island. Shallow shoals were extending wide, in the center there was a land with a radius of less than one kilometer.

Even so, there were trees and greenery typical of a southern country, it had the appearance a little like a private resort.

So that was how it was. If it was an island this small, then even an Entrance of another universe shouldn’t manifest here.

The Entrance that sprang forth from the collision with another universe existed everywhere all over the world, but there was a fixed rule about their appearing spot.

That rule was they could only appear limited in a land with certain surface size.

The reason wasn’t understood, but until now there had never been an Entrance discovered above the sea, there was also no confirmation of an Entrance on an island with a size below a certain limit.

For that reason, a Megafloat was a safe area.

At the event where they got near large land, meticulous vigilance was necessary, but an island this small was safe.

Kizuna was relieved and a.s.sembled the investigation device he brought.

“Err, I wonder if it’s fine like this?”

Because it would be a hindrance for the work, he called off his Heart Hybrid Gear.

{Yes. What’s left is just to push the switch, then it’s finished.}

The manual Kei created was extremely easy to understand, so the setting was finished without any trouble.

“Then, switch on.”

The investigation device was started up.

{Data transmission is confirmed. It will take around two hours for the data gathering, so during that time carry out the sample collection of the plants and minerals of the island. After completion, recover the device and go home.}

“Roger.”

Kizuna heaved a single sigh and dropped his shoulder.

“Ah, the setting is over already?”

Himekawa who was a little far away noticed him and called out.

“Yeah, it’s finished. I’m told that the data collection will take two hours as expected.”

“Then we will collect the sample just as planned. How about we divide into two groups?”

“That’s right. Although this is a small island, it will take more than two hours if all of us are together.”

They separated into two groups just as Yurisia proposed.

“Well then―, Cross – off.”

Yurisia removed her Heart Hybrid Gear.

“Eh, Yurisia-san. You took off Cross?”

“Yes. There is no enemy here. This is a southern island that we rarely visited. At the very least we have to let our hair down♪”

Himekawa and Aine looked at each other and followed along by removing their gear.

After that, with a reason to balance their combat strength, they were divided into groups of Yurisia-Kizuna and Aine-Himekawa.

Yurisia-Kizuna group would be in the south side while Aine-Himekawa group would investigate the opposite side.

The island was surrounded by white sandy beach, coconut trees were lining up along the beach.

Yurisia went ahead for just in case, so Kizuna was instructed to follow along from behind.

Kizuna followed that instruction and he was walking behind but――

“The scenery is really beautiful isn’t it―”

“Tha, that’s right……”

The scenery was beautiful, but the back figure of Yurisa walking was also beautiful.

Swaying golden hair. Under it was the large a.s.s wrapped in the pilot suit.

Voluptuous thighs stretched out from the a.s.s that looked voluminous, in accordance with those legs alternately moving forward, the a.s.s changed its orientation to the left and right.

Saying it frankly, his eyes were troubled where to look!

“Hey, Kizuna. That tree――”

Yurisia suddenly turned back. Kizuna was greatly shocked and averted his face.

“……”

His eyes swam around, he scratched his head, he had no composure at all.

Yurisia who saw his state made a really wide mean smile.

“It’s no good unless you properly listen to what I’m saying you know―”

Yurisia twirled and faced Kizuna. Matching that movement, her large b.r.e.a.s.t.s shook.

Kizuna’s eyes became nailed to that place.

Yurisia’s breast jolted to the opposite side as if hopping back, and then it returned back again to the original side. While that movement was repeated, its shaking was gradually settled down. His eyes were naturally chasing that shaking.

“Heyy, Kizuna-kuun?”

“Hah, yess-“

“It’s no good if you are staring that much☆”

She raised her index finger and closed one of her eyes.

“Uu…… ye, yes.”

After that, even when Yurisia was occasionally turning back, Kizuna was facing at the sea’s direction all the time.

Looking at Kizuna who was like that, Yurisia smiled thinly.

‘――He utterly has no resistance to girls doesn’t he? Like this then, something like Heart Hybrid will be impossible.’

“……Well though, as long as he is not becoming a burden, then it doesn’t matter.”

Yurisia leaked out a small murmur.

“Hm? Did you say something?”

Kizuna called her.

Yurisia smiled cheerfully and turned back.

“No, nothing. This is a rare chance, so let’s collect the samples around this area.”

“Aah, ri, right.”

Even after that, Kizuna kept getting fl.u.s.tered towards Yurisia’s figure in her pilot suit.

And then, the collection ended, and by the time they returned to the previous sandy beach, two hours had just pa.s.sed.

Joining Aine and Himekawa that had returned, they began the preparation for returning home.

“Then, we are returning ahead.”

Leaving behind Kizuna who needed more time to retrieve the investigation device, Aine and Himekawa would carry home the collected samples ahead of him.

“Okay. But, I might catch up with you two immediately later.”

“A race? Certainly Yurisia-san’s top speed is amazing, but…… if there is a handicap then I won’t lose.”

Himekawa was completely eager to race.

“Then, Aine-san. We too are going to race. The one who can return first to Ataraxia will be the winner.”

“H
