"MAANAAAAA! GAAAAH!"

From within the walls of Lily's backyard, a huge Hollow appeared, slimily dropping its own body, and inviting itself into her property. I had already set up the Magic Spell to call them beforehand, and they were coming by the dozens.

With a huge white mask as a face, and a body made up of black goo, it was quite the intimidating beast for any normal civilian Jenny wanted to into this world, so she better fight to earn her place now.

"See that thing slowly approaching you?" I asked. "That's a Hollow, if it touches you, you'll Mana will be drained out. They feed on Mana and are a nuisance that is born out of corrupted Mana and Negative Emotions that we humans exude all the time."

"E-Eeeeh?! So there's not just the monsters from the gates?!" Jenny cried.

"Nah, this world had always had monsters in it, but not as many as of now Hollows used to be rarer." I explained. "Until the gates appeared, filling the world with Mana, meaning more of these invincible guys, which only mana-wielding people can see, began to multiply, and diversify. We deal with these guys every end of the week to gain some resources out of them."

"S-So you've been cleaning and protecting our city all this time F-Fighting these ugly things?!" Jenny cried.

"GRUOOHHH!"

BAAAM!

The slimy hollow suddenly grew a huge arm, hitting the floor and generating a shockwave that threw Jenny away.

"Uwaaagh!"

She fell into the floor with a loud thud, rolling over the ground. Her armor protected her well.

"Ouch Y-You damn ugly monster" Jenny cried. "H-Hey, can I kill it with the power I have?"

"Hmm, it must be an F Rank Hollow, nothing special about it. But more are coming though." The Great Spirit explained. "Girl, if ya wanna join, you should at least be able to take them down by your own!"

"O-Okay I get it!" Jenny nodded, swallowing saliva. "I-I'll do it"

FLUOSH!

Her Mana Aura surged from her body slowly, as her ring and bracelet reacted to them, covering her club with a purple aura, resembling a small Viper Drake coiling around her bat.

"Hyaaaaah!" She ran rather clumsily towards the Hollow, who was dumbly glancing at her.

"OOOOOHH!" The Hollow roared, rushing towards her.

"Hit it as hard as you can, girl!" Rita laughed.

"This feels like we're babysitting her" Mark laughed.

"It definitely didn't felt this way with me, right?" Lily wondered.

BAAM! BAAM! BAAAM!

Jenny started hitting the hollow's body with her huge bat, generating small explosions of poison around its big and slimy body.

The Hollow cried, squirming around in pain, but it attempted to wrap its own body around Jenny, while touching her and slowly draining her Mana

"Uuuggh! Dammit! Is this really an F Rank monster?!" She complained.

"Put more strength in those arms of yours!" Rita said.

"ARGGHHH!" Jenny screamed in desperation, her eyes suddenly glowing bright red, resembling the eyes of the Viper Drake Queen. "You damn FUCKING PIECE OF SHIT!!!"

Her arms suddenly overflowed with venomous and poisonous mana aura, as she unleashed an explosive strike that generated a huge viper drake jaw, biting the entire Hollow's body, and splattering it into mud!

CRAAAASH!

"GUOOOHHHH!"

SPLAAAT!

Like a balloon, it exploded, the F Rank Hollow was defeated just like that! a small Hollow Crystal was dropped, and Jenny found herself covered in their muddy black material.

"Ugh This is the worst, it felt like I was going to get swallowed" Jenny sighed, falling into the floor while holding the crystal. "And what's this?"

"A hollow crystal." Mark explained. "It is pretty much the crystallization of the corrupted Mana that hollows hold inside of them, we purify them and use them to grow stronger by absorbing their magic power. Normal monsters also have something similar named Magic Crystals, they come purified already, mostly."

"We fought monsters back in the countryside, on Elayne's home, there's a few normal animals that became monsters but it's quite rare to find them in the city." Said Rita.

"Well, if we ever go there, I would love to meet Elayne's family, and hunt monsters!" Lily said.

"Sure, I was thinking on going monthly to my house, both to check on my family and regulate the monster population. I know there's government agents there and all, but I doubt they can just clean it all efficiently." I said. "Anyways, they're here, everyone! Let's get ready."

"MANAAAA!"

"SO HUNGRY MANA"

"NEED MANA!"

"GRAAAARRGGH! MOVE ASIDE!!!"

Suddenly, a larger and more monstrous Hollow appeared from within the group of F Rank ones, was it an E+ Rank? They usually take larger and more monstrous forms.

"SHAAAAAH!"

CLAAASH!

It landed in the middle of the backyard, it possessed several heads and tentacles, with a few of its legs resembling those of an enormous spider.

"A Hollow Legion?! One of them already formed so soon?!" The Great Spirit was shaken.

"MANAA! HAHAHA! DELICIOUS! I'M GONNA GOBBLE YOU UP!!!"

The many heads it held, each one made up of a white mask of a different shape, laughed, the huge body of the Hollow Legion was over ten meters tall, and it was a monster comparable to some D Rank threats.

"GRAAAAARGGH!"

Its countless faces merged together into a grotesque, monstrous jaw resembling that of a spider, opening up and quickly attempting to devour me.

"ELAYNE!"

Jenny panicked, as the beast's attack landed without me or anybody doing anything about it

CRAAAASSSSH!

Smoke spread out as the impact reached me. Jenny opened her mouth wide open, but Well, nothing happened, I was completely unscathed, as my body was covered on a combination of spiritual barriers and Yggdragon's scales merged together.

A powerful magical and spiritual aura was surging from within my body, as I felt almost no damage from an otherwise lethal blow

"The upgraded equipment seems to be working as intended All these damage reduction Skills are really useful." I giggled. "Now [Yggdragon's Life Flames]!"

My bracelet glowed brightly, imbuing my hands with golden flames of life, as I unleashed a blazing explosion right in front of the Hollow's face.

BOOOOOOOMMMM!

Thankfully, we had already set some sound dampening charms and illusion barriers, hahaha
