SÅ Akiyama is living with his childhood friend Kaori Sasaki, both attending Uchihama Academy and are members of the Astronomy Club. Along with fellow club members Nagisa Hanamiya, Airi Hasekura and Kenny Osafune, they deal issues of other clubs. After she confessed her true feelings to SÅ, Kaori gets involved in an accident when a bus lost its control. In the credits scene, the Astronomy Club room experiences a earthquake-like shake while Nagisa's black box suddenly illuminates. SÅ then checks the floor above and finds an unconscious girl.
