**Kubomi**

Lil shit 

A demon who's rude af

He's the king of hell, and intends to keep it that way.
He does feel the need to be around humans, which don't involve just making deals with them. He likes their technology and culture, all that jazz.

Kubomi gets fascinated my human hearts, he really feels a weird connection with it. And that is why he always aims for the heart, no matter the enemy. (Think of it as his special attack, he uses his tail to take the heart out and then consume it)

Kubomi is immortal, he's the only character I intended to make a gary-stu.
He still gets injured ofc, but he just doesn't die.
Which is really unfair to the other demons in this hell universe.  

In which, any demon can be king long as they can kill the current king.

But, as said, Kubomi doesn't really intend on giving his position.
