Legends surround everything, especially old school buildings. The Private Seikyou Academy is not an exception. It is rumored in the said school that sixty years ago, there was a girl that was left to die in the old building. Dusk Maiden of Amnesia focuses on Teiichi Niiya, who, for some reason, is able to see the girl's phantom. Now he is, perhaps, the only person to reveal the mystery of Kanoe Yuuko's death.
