The Twilight Maiden and Amnesia

There are many creepy legends at Seike Academy, and almost every one mentions a ghost named Yuko. The school has even created a club for the study of the paranormal, where the main role is played by 13-year-old psychic Taiichi Niiya, who knows how to communicate with spirits. He is supported by Kirie Canoe, a high school student with spiritual abilities, and Momoe Okonogi, the energetic secretary of the club. But the president of the club, the mysterious Yuko Canoe, is invisible to everyone except Teiichi and Kirie. It turns out that Yuko is the very ghost of the school. She does not remember how she died, but she feels that her death was terrible and could threaten her descendants. Together with Teiichi and the others, Yuko hopes to uncover the truth about her death through mysteries and urban legends.
