He works as an editor for JUMP and is best known for his role overseeing Gintoki's serialization. Gintoki first encounters him in episode 100. Fans often note that he's a running joke in the series—constantly ribbed by the cast for his short stature. Before landing his editor gig, he'd actually dreamed of writing for fashion magazines, which occasionally gets played up for laughs when his more refined sensibilities clash with the chaos of managing a shonen manga.
The character is a nod to Kohei Onishi, a real JUMP editor who worked on both Gintama and One Piece.
