Toribi: Prelude is a pretty clichéd story about a boy (Hum) and a girl (Maria) who are childhood friends. One day, Hum reveals to Maria that soon he will be moving away to the countryside to go to boarding school there, and that the two of them only have seven days together before they will be separated. In this game, you play as Maria in her final week with her best friend.
