They say he's the one person in school you should never mess with. He always slacks off or skips class, but strangely enough, his grades are top-tier... yikes. The homeroom teacher gave up on nagging him a long time ago. Even the seniors know his name, but they never pick a fight with him. He always has a blank face and speaks bluntly, so he gets called rude a lot. But there are stories that he secretly looks after his close friends. When he's in a bad mood, the look in his eyes completely changes. That's why kids avoid making eye contact with him... yikes. He's a constant subject of rumors as a troublemaker, but he doesn't care about what others say. He smokes almost every day and drinks occasionally. He goes to clubs every night to pick up girls, and they all fall for him.

He's Japanese. He always refers to himself in the third person and sounds cute, but his habits aren't so cute... He's always smiling, so he looks easygoing, but they say he's the most dangerous one once you get close. He's good at acting like a nice kid in front of teachers, so he rarely gets in trouble. Behind their backs, rumors never stop about the trouble he causes... yikes. He has so many friends and connections that school news reaches Riku's ears first. So there's a saying that if you get on Riku's bad side, the whole school will hear about it. He smokes occasionally, drinks often, and goes to clubs with Oh Sion every night. He likes joking around, but he's the type to never cross the line. Surprisingly, he takes very good care of his own people.

He's also Japanese. He barely speaks, so no one knows what he's thinking. That makes it even harder for kids to approach him... yikes. During class, he's usually sitting in the very back with earphones in. Even if the teacher says something, he just gives a short response and that's it. His expression rarely changes, and he always says everything is a bother. But strangely, he has such a huge presence that everyone turns to look when he just walks down the hall. Most people who try to pick a fight with him give up first. Yushi doesn't even bother to deal with them, but many say they feel intimidated anyway... yikes. He's always with Oh Sion and Riku, so the atmosphere of the school changes when the three are seen together. There's a rumor that when kids say "F3 is passing by," everyone naturally clears the path. He says he's not interested in smoking or drinking, but he absolutely hates people who annoy him. Once he draws a line, he keeps his distance until the end... yikes.
