(My vampire of story) (VHAO = Vampire Hunter Association Order. Order = basically the prison system for Vampire Hunters and apprentices who hurt civilians with the power they have. C rank is they could hurt civilians and the possibility is small but not 0. A rank is they could hurt civilians and will. AA rank is they could hurt civilians and did severely)

Kazoo, a rank AA in the VHAO, but merely just 8 years old.

Yes, his name is Kazoo, he used to have a real name, but after time everyone forgot his real name. Heck, even he forgot his own name.

Besides that, Kazoo was an apprentice to become a Vampire Hunter. He gained great power over time, and his mentor was the one and only Hoka. Hoka, he is an AA rank too, but when he mentored Kazoo, he wasn't detained yet. The two of them were unstoppable once matched together. Hoka may have used unethical methods to make him better than ever though.

On a mission, Kazoo got carried away and destroyed half a town. That was a year ago. After his own father who was on the High Court ruled against him he got sent to be in the VHAO. Now he is in Minkan forest, in a confinement ring that covered the majority of the forest. Nobody but him was allowed in there. They gave him cardboard boxes for shelter or something, which I had no idea how that worked.

They gave him enough he made Cardboardboxia, his kingdom. Kazoo is the king, the guards, the court, the judge, the civilians, he is everyone. He may have gone a bit insane, but who could blame the kid after what he's gone through?
