Kinose Azusa

Azusa represents the Sagittarius. Although he is a newcomer to the archery club, he has met Tsukiko before and inspired her to become better at it. He is cocky, confident of himself and he declares himself as a natural genius. Azusa often flirts with Tsukiko and his actions annoy Ryunosuke a lot. He is a first year.

Spoiler

He is in fact insecure of his abilities as he can't put his heart into anything.
