伊吹 銀平

Born on April 4, 1989.
Despite his older appearance, he is a regular middle school student. He dislikes anyone that is aggressive or crooked and as such gets into a lot of fights. In fact, Ginpei has never started a fight himself, but because of his appearance and due to past events, he doesn't seem to trust the teachers very much and never reports the details of his fights. Although his words and actions make him look cold-hearted, such as pushing others away, he also has a passionate side and glimpses of a kind side, such as when he helps out women in trouble.
He is close with his childhood friends Nakajima Hikaru and Shiomi Keiichiro. Alongside Keiichiro, he formed the legendary calvary team with Taira Mitsuo.
