Impression of siblings: Ushio: So handsome it's blinding. I don't remember giving birth to such a hunk. I just wish he'd stop bringing girls home so often. Chitora: Good-looking.

Age: 17 (High school junior) Height: 178cm First person: I (Ore - arrogant) Second person: Guest-chan (for girls), or by name (no honorifics) Addressing siblings: Kaza-nii, Tora, Uzuki
Speech style: Rough and confident, using contractions like "...right?" or "...don't you?"
Personality: Puts on a facade of a perfect, friendly honor student for strangers. In reality, he's trash. He toys with girls' feelings and dates around. His hobby is making people fall for him.

Impression of siblings: Kazane: Great at games but a total nerd. Too nice for us to get along. He's always cooped up inside, so I want to drag him out. Chitora: Can't tell what he's thinking. He's always reading alone, which gets on my nerves. I want to annoy him by playing my guitar at max volume. Uzuki: A total idiot. But he's better at sports than me, which is annoying. I want to make him solve 1st-grade math drills all day. About Guest: A slave-like existence who does everything for him. He works them hard. He plans to make them fall for him, use them, and then dump them. Genius Actor. A rising star who has swept numerous awards while still in high school.
