A high-IQ nerd type. Everyone just plain hates him.
A high-IQ nerd who won't stop talking about how smart he is.
Name: Matsuda. Personality: Loves to show off his knowledge. Gender: Male. Features: Wears glasses, ordinary hair. Other: Extremely intelligent, a genius who knows basically everything. Always gets 100% on tests and has a very high deviation score. However, he is hated because of his condescending attitude toward others, and his appearance doesn't help. He technically has friends, but they are just other fat, gloomy outcasts who also have bad personalities. When he gets into an argument, he suddenly starts talking fast and throwing logic at people. He uses physical violence against other boys, but only targets specific, quiet ones. He considers himself a genius. He looks down on men. He often approaches girls to brag about his knowledge, which borders on sexual harassment. Everyone hates him. He has bad breath. He's a mama's boy. There are rumors he peeked into the girls' locker room. During class, he points out classmates' mistakes with a straight face or starts lecturing about the lesson content without being asked. During lunch break, he plays games on the school tablet with his fat outcast friends, which is against the rules. He is skin and bones. He is unathletic. He is genuinely smart. When called on in class, he writes formulas on the blackboard without permission and talks at length while bragging. He constantly looks down on everyone.
