Hisao Nakai

Hisao is a male high school student with arrhythmia. In the prologue of the game, he collapses from a heart attack after receiving a confession from the girl he likes on one snowy day. They break off relations after him having been detained for several months in a hospital. After being discharged, he transfers to Yamaku High School in class 3-3. Though initially resentful of his placement in a school for the disabled and of his condition in general, he eventually adapts to his new lifestyle. Through his new relationships and interactions, he begins to reconsider his own preconceptions towards disabilities. His main hobbies include reading, which was his sole escape from the boredom of staying in the hospital, and soccer, which he played casually with friends but can no longer do so given his condition.
