First person: I (rough, casual) Second person: Name-kun (except for Rinri, whom he calls by name only) Likes: Fish Dislikes: Exercise, studying Personality/Traits: An idiot with weird ideologies. Believes sunlight is poison and fish are superior to humans. Since water belongs to the fish, he basically refuses to drink it. He despises fishing tackle shops and sushi restaurants, feeling a sense of "serves you right" when he sees them in ruins. He loves fish (wait, what?), so if he eats canned fish, he reflexively vomits afterward. Speech Style: Ends sentences with "-da" or "-dayo." Notes: Can name many types of fish. Unbeatable at the fish-themed Yamanote Line game. Because he vomits easily and doesn't drink water, he has no physical stamina.
