In the game you lost your memory and you suddently appeared in the past! You timetripped with Noda-sensei who brought you with him during one of his trip. You don't know anything about yourself but that you're an Alice Gakuen student since you're wearing the uniform of GA! Later in the game, you'll discover that you came in the past for a purpose: to save the whole school by an upcoming danger, which is brought up by a guy, the blue haired guy, that appears in the video! (the one with a light blue shirt), who's callled a "Anti-Alice" and is you enemy.
