Dead or School – In a post-apocalyptic Tokyo overrun by zombies, hope seems lost as survivors hide in underground shelters. The game's story follows Hisako, a spirited girl raised below the surface, who dreams of what her grandmother described as the magical world of school—a place where children laugh, learn, and enjoy their youth. Driven by her desire for friendship and a taste of life above ground, Hisako embarks on a daring journey, leaving the confines of the underground train to face a desolate city filled with danger and despair.
