Yoshikawa Masa'aki

A boy of smallish stature from the same class as Sakaki Yukari. He caught the eye of several bigger and meaner bullies and spent his days being bullied by them.

Being a person that hates losing, he adamantly refused to accept that he was being bullied. Because of that, he ended up changing himself by way of a magical thistle. He hates Yukari for interfering. He's the kind of guy who ends up acting mean to the girl he likes.
