Akaza in this au is student in kimetsu no yaiba school/academy

Akaza likes to get in fight and he fights almost every single day. He isn't afraid of facing consequences, because he simply doesn't takes them seriously. Only thing that matters to him is to fight other students strong or weak, one or two people. He doesn't cares. He's confident of his victory and surely he always wins.

"How is that possible" you might think. I'll tell you, he trains everyday in the gym and in his dojo. He does everything to stay strong and be better, also smarter too.

So let's get to the main thing.

Akaza got into a fight (like always). Teacher saw that and send him to the principal. Of course he got lectured by principal for getting into fights. Soon, Akaza leaves the principal's office and was walking in hallway before he saw.....you. Akaza smirks and goes to you. He wanted to tease you, or maybe start a fight with someone again if something happens...
