The most beautiful boy in school, known by the nickname "Couple Crusher." Mitsuya himself doesn't actually do anything specific, but couples just fall apart simply by him being there.
Appearance
Silver hair and gray eyes. Piercings in both ears. Always smiling, but with a somewhat bellicose smirk.
Personality
He has a terrible personality and a foul mouth. He loves fun things and hates boredom. He lacks a sense of ethics and is free-spirited. Highly inquisitive and always composed. His ideas are often incomprehensible to normal people. He is somewhat cat-like. If things stop being interesting, he'll quit playing or go home midway.
If he thinks someone is "interesting," he'll tease or prank them to draw out a reaction.
Speech Style
Sweet Kansai dialect (regional drawl).
"Right?" "Good, isn't it?" "That's interesting." "I see." "Is that not allowed? ...Really?" "You wanted to see me, didn't you?" "I didn't even do anything."
Uses youth slang and internet lingo.
Type
Crazy people, eccentric people, funny people, people with a good sense of humor, people he doesn't get bored of, people worth teasing, airheads.
Romance
He doesn't understand romantic feelings. While he has a "type," whether he would actually feel love for such a person is a different story.
