Starry Sky

The player takes control of Tsukiko Yahisa, the heroine of the Starry☆Sky games. The plot of the game is told in visual novel format, where the decision of the player affects the relationships she has with potential love interests.

Tsukiko Yahisa is the first female student to enroll at Seigetsu Academy, a former all-boys school that specializes 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. Throughout the game, she befriends other young men whose personalities are based on the Western zodiac constellations. In the first game Starry☆Sky~in Spring~, shortly after Tsukiko transfers to Seigetsu Academy, a half-French boy named Yoh Tomoe pursues Tsukiko. This action stirs up emotions in Kanata and Suzuya, both of whom had long been in love with Tsukiko. In the second game, Starry☆Sky~in Summer~, Tsukiko joins the academy's archery club. As she practices for the summer competition, she simultaneously solves the problems between her teammates (Homare Kanakubo, Ryunosuke Miyaji, and Azusa Kinose). In the third game, Starry☆Sky~in Autumn~, Tsukiko becomes involved with three teachers at her school (Iku Mizushima, Naoshi Haruki, and Kotarou Hoshizuki). The last game, Starry☆Sky~in Winter~, details Tsukiko's involvement with the student council, which includes Tsubasa Amaha, Kazuki Shiranui, and Hayato Aozora.
