There are no classes in the black academy of complete neglect.
　So I was solely holed up in the library alone, reading grimoire books.

　The exterior of the library is, of course, a shambles, but the number and quality of books is very good.
　By the way, perhaps because it is imbued with magical power, I am grateful that the deterioration of the books is not too severe for the building.

　Admission (?) It's been about six months since, and I've already read about a third of the book.
　Thanks to that, I've become quite familiar with black magic.
　In fact, I'm probably making much more progress than taking classes.

　Of course, magic is not something that can be said to have been mastered simply by reading books and acquiring knowledge in one's head.
　That's why the library had a special room set aside for the actual use of magic.
　It seemed that there was no problem trying out magic there.

　I put the book with the hoary title of 'Magic to Turn Humans into Deformed Monsters' (as well as the contents) back in its original position, and picked up the next book, which I had finished reading in about ten minutes.

'Hmm?　Weird book, huh?　It doesn't say the title or the author's name, does it?

　It's a book that's solid and heavy, and looks like it's quite a good read.
　Other than that, at first glance, it looks like a nondescript grimoire, but there was nothing written on the cover.
　The same goes for the back cover and spine.

　I opened it up.

''Huh!''

　In the next moment, an enormous amount of magical power flooded out of the book, and every hair on his body stood upside down.

''........What is this?''

　The book was all blank.
　He looked around as he stood up.

　The same scene of the library as before.
　No--.

Who are you?

　There was a presence on the bookshelf that hadn't been there a moment ago.
　It was sitting cross-legged and graceful.

　A human?
　That's a strange sign for that.
　That's a much worse presence.

I see. A demon.
Yeah, that's the answer.

　Crackle.
　The guy clapped loudly, as if on purpose.

　He looks like a human man in his early twenties.
　He has a thin body and pure white skin.
　His black hair is pulled back sharply, as if in rebellion to the heavens.

　The eyes with sharp eyes are reddish, and they look down at me while twisting their bright red lips as if they are enjoying themselves.

''Thanks. Thanks to you, I could go out there. It's a shame that what I did with you is now locked up in a book.

　Apparently it was my opening the book that got me out.

I never thought I'd be locked up for this long. None of the people in the academy have ever picked up a copy of this book before.

　Well, it was at the bottom end of a bookcase in the back, on the bottom row, which was even less obvious.
　If you're not someone like me who reads through them in order, you're not likely to pick them up.
　The people in this academy only seem to be interested in their own area of expertise.

I'm sure you've been a big help to me. I owe you a debt of gratitude. ........we should thank you for that, shouldn't we?
I don't need it.
Don't be so harsh. By the way, I want to return to my hometown in the demon world, and to do so, I need a fresh sacrifice.　--Yeah, that's it.

　The demon looked around to lick my body with its red eyes and collected them like it was deserving of it before saying

''You're going to be sacrificed to me, aren't you!　So that's how you thank me for helping you!　Heehahaha!

　Sacrifice?

You see, we are only using your flesh and blood as a catalyst. I won't even take your soul. But your soul will be forever wandering the earth.　Heehahaha!

　I say flatly.

"Hmm. I'm sorry, but I have to say no.

　Why should I have to sacrifice myself for a demon who doesn't know what horse's bones I am?

　The demon cleared his throat, "I'm sorry, but you have no veto power!

"I'm sorry, but you don't have the right of refusal!
Speak for yourself. --Explosion.

　I aim at the demon and unleash my magic.
　But .....

"...?　Not activated?

　The technique should be correct, but the magic power doesn't converge as it should, and it ends up being a dud.

''Gahhahahaha, useless, useless, useless!　You're already inside the wards I've deployed.　It's a wizard-killer's ward that blocks all kinds of magic.

　I had an uncomfortable feeling as if something sticky was covering my entire body from earlier.
　Apparently, I was already in the middle of this guy's magic.

I'm sure you'll be able to find out what's going on in the world," he said.　You can't do anything about it, can you?　Of course it's no use trying to escape!

　Surely, this isn't going to be able to use magic.

'Then we'll just have to fight with this.

　I pulled out the wand that I was holding at my waist.

　It is an auxiliary staff for wizards.
　It seems to be cheap to set the direction of magic with this, and most of the students have it, but I didn't have it because I didn't need it.
　Then the teacher of the blue academy, Hengel, who found out about it, gave it to me as a gift for some reason.

　I haven't used it yet, but I've been carrying it around with me like this, just in case.
　I'm going to be able to make use of this device.
　Of course, it's not to be used as a magic wand.

　I held the staff up like a sword.

You can't get away with it.　Using your magic wand as a bludgeoning weapon!　It's a pretty good idea, huh?

　The demon sneers like a fool.
　The atmosphere is such that they don't even think they can fight with such a thing.

You know what?　A true swordsman does not choose his sword.
It would have been a little more convincing if the swordsman had told you that.　By all accounts, you're a magical...

　I kicked the floor, closing the distance between me and the demon in an instant.
"It's a shrinkage.

--?

　Perhaps because I was completely caught off guard, the demon wasn't even able to react.
　I unleash a slash(──) shot with my magic staff to its defenseless body.

　Zubak!

　The demon's torso was sliced cleanly off from his right shoulder to his left side.

'How's that?　You can slash with a cane, right?
