Tsukiko Yahisa is the first female student to enroll at Seigetsu 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. Throughout the games, she befriends other young men whose personalities are based on the Western Zodiac Constellation.
Tsukiko Yahisa- The main character you play as throughout the game ( Although the Player may change the character's name in the beginning of the game). Tsukiko is a second year student at Seigatsu Academy. Before, Seigatsu Academy enrolled exclusively male students. They recently began to accept female students. Since the academy is in a rural area, she is the only female student. Tsukiko is accompanied by two of her childhood friends, Kanata and Suzuya. She belongs to the Astronomy Department.
Yoh Tomoe- The new transfer student of Seigatsu Academy. He was a friend of Tsukiko when they were children. Being half Japanese and half French, Yoh was bullied. Because of this, he had a hard time opening up to people and learning to trust others. However, Tsukiko always treated him kindly. As time passed, Yoh fell in love with her and decided to enroll in Seigatsu Academy to pursue her. He belongs to the Astronomy Department.
Kanata Nanami- One of Tsukiko's childhood friends. He is a hotblooded guy that has loved Tsukiko since they were young. Despite his tough exterior, Kanata has a serious heart condition that he inherited from his father. He cannot stand being treated as a weak or ill person and often skips out on hospital check ups. He often picks fights with others since it makes him feel alive and less weak. He belongs to the Astronomy Department.
Suzuya Tohzuki- One of Tsukiko's childhood friends. Like Kanata, he has loved Tsukiko since they were children. Suzuya has a gentle personality and watches over Yoh, Kanata, and Tsukiko. He is skillful in cooking and is often compared to a mother. However, he is actually very possessive of Tsukiko and is easily jealous when she is with other boys. He is also very intimidating when angered. He belongs to the Astronomy Department.
