Killua's Roommate Might Be A Thief, Or He Might Just Be A Demon From Hell

[ KILLUGON ] Killua's roommate, Gon, is a demon from Hell attending a religious college and Killua is determined to get to the bottom of this.

Problems arise when Gon refuses to return to Hell, and thus spawns the Unholy Trinity: Hisoka, Chrollo, and Meruem. They arrive to drag Gon back kicking and screaming if they have to-but not before cleaning up the mess Gon left behind as he was learning how to be human.
