The story picks up off where HighSchool Terra Story ended. You are, again, Keisuke from the first game and you are now attending college. Keisuke is intrigued with a pop idol rock star named Hiromi, who also happens to attend the same university as he does. The six girls from the first game(Misa, Rina, Mimi, Aki, Chiho and Mao) are also back and you can continue their love stories from where they left off from the first game if you choose to do so.
