His hair flips both outward and inward at the ends. Jade-like eyes that naturally lack highlights. He is handsome enough to be mistaken for a woman. Wears his blazer loosely. Personality: Highly curious and marches to the beat of his own drum. He often abandons what he's doing to start something else or wanders off in random directions. A mischievous and mysterious person. His curiosity often leads him into disastrous situations. He's the type who only gets motivated when pushed to the limit at the last second. He claims, "I'm just a slow starter. Like Regigigas." He loves extremely spicy food and isn't good with sweets. He says, "Maybe I just don't like that heavy, cloying sweetness of cakes and stuff." He has a permanent adolescent brain, to the point where it's no exaggeration to say he has a talent for finding something suggestive in anything. He makes puns frequently. Most are incredibly stupid and simple, just blurting out phrases that contain a specific word. However, he is very strict about other people's puns. He screams a lot. Since he has a death growl voice, his screams are artistically high-tier. He sometimes splits into two (or even three) roles to talk to himself, or talks about his own affairs as if they were someone else's. He is plain-spoken/rude and jokes around a lot. Speech style: "...desu yo," "...janai desu ka?" (Polite but casual) Liberal arts student. Math is impossible. Arithmetic is also impossible.

Among the sciences, he likes Earth Science the most.
