Imprisoned without explanation for a decade by a wealthy former schoolmate, Goto now comes to the endgame against his tormentor. If Goto cannot uncover the secret behind the schoolyard grudge, he'll earn his death and the death of the girl he loves - just as his adversary will accept death if Goto can unlock his memories and the meaning behind them. But there's more to the game locked away in memories, and even the end of the game may not mean the end to the war!
