10 days later.

The academy exchange starts today.

Me and Ray returned to our room from the dining room and Ray immediately collapsed on the bed.

Going to sleep? (Arnos)

Yeah. Weve still got time. (Ray)

After eating so much Ray must have become sleepy because he immediately fell asleep.

At the same time, a tapping sound started coming from somewhere.

The window?

Nn?

Opening the window I could see Misha outside.

Whats wrong? (Arnos)

Cat-san. Nyaa. (Misha)

When Misha called out a familiar black cat came running over.

After jumping on Mishas shoulder it then jumps onto my window sill.

One of the old seven demon emperors Aivis Necron.

Whats happened in Deiruheido? (Arnos)

Like Melheys I instructed Aivis to investigate Avos Dillheavia in Deiruheido.

He must have urgent business after coming all the way out here.

Three of the old seven demon emperors have disappeared from Deiruheido. (Aivis)

Oh. Where have they gone? (Arnos)

Ive confirmed that theyve entered Gairadeite but I lost them in this city. They definitely havent left it though. Theyre hiding here somewhere. (Aivis)

This happened at the exact same time as the exchange? No way this is anything other than planned.

Any relationship with the hero academy? (Arnos)

I dont know yet. I have a network of human contacts in the hero academy but none of them has seen the missing emperors yet. (Aivis)

If Avos Dillheavia and the hero academy are colluding together that makes for a plain but understandable situation.

Understood. Continue looking for any movement of the missing emperors. (Arnos)

Your will. I have one more thing Id like to tell you. It may not be related to Avos Dillheavia but its still worrisome. (Aivis)

Whats that? (Arnos)

On my arrival here I overheard some humans talking about the legend of the deep darkness. (Aivis)

Fumu. Didnt that storekeeper say something about that as well?

What is that anyway? (Arnos)

Its an oral tradition passed down amongst the humans for a long time now. It says that soon the deep darkness will once again swallow Azeshion but dont be afraid and offer prayers and hope to our legendary hero. If you do, he will return and the light of hope will clear away the darkness. (Aivis)

Thats a very common legend.

This deep darkness could be the demon king of tyranny. (Aivis)

You think its a legend prophesising my reincarnation? (Arnos)

I do. It could have been handed down so they know to kill you when you are reborn. (Aivis)

Fumu. Whats your basis for that thought? (Arnos)

After it piqued my interest I looked into it and found that this tale had been passed down and spread to the whole of Azeshion from the students and graduates of the hero academy. The deep darkness is said to bring despair to the humans but the heroes never explained exactly what it is. (Aivis)

Its probably only the deep trust that they have in the heroes that allowed such a vague rumour to spread. Humans have always believed in the strangest of things.

In other words, since the hero academy is mostly unknown to the mazoku they are plotting to kill the reincarnated demon king again and this time around they even want to destroy his origin so he cant revive. (Arnos)

I believe it was done that way on purpose because if it specifically mentioned the demon king of tyranny us old seven demon emperors would have heard about it. This way they can avoid a confrontation with Deiruheido by calling it the deep darkness. (Aivis)

The world became peaceful and interactions between the humans and the mazoku were cut off. Were they waiting in the shadows while publicly pretending to forget?

Its not an impossible story but theres some inconsistencies. For one, the name of the demon king even here in the hero academy is Avos Dillheavia. (Arnos)

Really? Are you certain? (Aivis)

There seems to be a gag order on that information but one of the students let it slip out. Im not going to say Im definitely correct as they may be lying about the name but lets just say Im very sure its correct. (Arnos)

Aivis falls into silence while thinking.

If they had managed to keep a legend about the resurrection of the demon king of tyranny going for 2000 years all the while looking for ways to defeat him you wouldnt have thought theyd get his name wrong. The hero academy will never fight me because they are looking to fight the false demon king.

Is it possible the plans of Avos and the hero academy are connected with each other to create this situation? (Aivis)

Possibly and three of the old seven demon emperors have come here. (Arnos)

Theres three camps in Gairadeite now each with different expectations. Theres Avos, the heroes and this me.

The chances of nothing happening is none existent.

Theres also the chance of other unexpected situations appearing as well.

You chase after the demon emperors whereabouts and Im going to search the academy since today is the start of the exchange. (Arnos)

Your will. (Aivis)

Aivis jumps out of the window.

Work? (Misha)

Misha grabbed onto the window sill and pulled herself up but only enough for her face to peep in for some reason.

Work? (Arnos)

Demon king work? (Misha)

Ahh, I see.

Pretty much. Looks like weve come to a troublesome place. (Arnos)
