The primal douche. He's so jock but also a bottom. I guess he fits the category of Tsundere. He falls for Serinuma but over the course of the show he get's literally NO SCREEN TIME with her. I only know this cuz I'm a fucking weeb and I read the manga. Again, mostly looking for quality of voice so don't worry too much. Serinuma ships him with his best friend Igarashi. If Igarashi's voice is romantic, compliment it with something more boyish/manish.
