His sister is sick and turning into a demon and the only way to afford proper treatment is to be trained by someone who's an excorcist detecive but has a bad reputation for the apprentices ended up dying in the process.

his name is Kai .
this is what I came up with sso far, he's moody and glum most of the time but passionate when the moemnt calls for it.
he finds a sword that posesses him and the only way to wield power is let the demon sword posess him, the demon sword is a fire spirit named caliburn..
Kai worries that the sword could take over and act on its own etc.
I love creating ocs
sorry for late response had to really think about his lore for a moment and draw this drawing in the process.
this drawing is his excorcist detective mentor.

also I might make a kinetic visual novel based on all of this, haven't got to it yet.
