A stubborn narcissist that has very little patience for anything or anyone. Unlike his other three friends, he has no "charm" of any sort to hit on girls with, only his looks and bad attitude.
Kyohei fears nothing and that includes Sunako's doom and gloom. He's constantly yelling at her for who knows what and he's the only one she'll react with strong emotion to. The two share a complicated relationship revolving around understanding each other and hating the other's guts.
When it comes to what he wants, it doesn't matter rain or shine, dressed or half-dressed, he'll get what he wants no matter what. Kyohei is a man who will not take no for an answer and often questions everything around him, or just complains about it in general.
Due to his popularity, he has a large fan base which he hates more than Sunako's doom and gloom routine.
