Hoshiguchi Jun

A male student attending Minkei Academy and is Ryuu's classmate. A short and weak four eyed boy. He has a sarcastic and show-off side but is usually an earnest guy. It's easy to tell when one hits the mark with him as it shows on his face. It seems he's not aware of this habit of his though.
His zodiac sign is virgo and his hobby is taek wan do. It seems like he likes Kurisu Kanu, but he denies that.
He witnessed the masked woman committing manslaughter during the Mirokujima investigation, and later he was swallowed by the hydrogen bomb explosion.
