Starry Sky in Spring

Tsukiko Yahisa is the first female student to enroll at Seigatsu Academy, a former all-boys school specializing in astronomy. She is closely watched over by her childhood friends, Kanata Nanami and Suzuya Tohzuki, who often protect her from the male student body.

Not long after Tsukiko transfers to Seigatsu Academy, a half-French boy named Yoh Tomoe follows suit to pursue her. This action stirs up emotions from Kanata and Suzuya, both of whom had long loved Tsukiko.
