Dusk Maiden of Amnesia (黄昏乙女×アムネジア, Tasogare Otome × Amunejia^?) is a Japanese manga series, written and illustrated by Maybe. It was published by Square Enix and serialized in the Monthly Gangan Joker magazine. An anime adaptation by Silver Link aired between April and June 2012. It has been licensed by Sentai Filmworks in North America.

The story revolves around a first-year middle school student, Teiichi Niiya who had just enrolled at Seikyou Private Academy. When he gets lost in one of the school's old buildings, he meets a girl named Yuuko Kanoe who reveals herself as a ghost with no memories. Teiichi then decides to investigate her death by looking through the school's seven mysteries revolving around her. Throughout the story, Teiichi and Yuuko discover the truth about these ghost stories while helping those who are troubled. It is discovered that Yuuko has no memories as she forced her entire reason for existing into another dark form referred to as "Shadow Yuuko". If she can accept this part of her, she can remember why she still is trapped as a ghost, i.e. her final wish. When they discover 6 of the seven mysteries Yuuko's sister (now an old woman) reveals that there was only ever 6: the seventh one never existed. At this point Yuuko decides to accept her shadow half and she tells Teiichi her reason for remaining on earth; 60 years ago there was a plague in their town. According to popular belief the plague was caused by the gods as Yuuko's family who was supposed to perform a certain ritual for the gods neglected their duties. Due to this the townspeople became very antagonistic towards the Kanoe family. Also the only way to lift this curse was for Yuuko's father to sacrifice that who was closest to him which was one of his daughters. To avoid choosing he planned on leaving the town for a time. However Yuuko's sister was so influenced by the people she believed them to be right. So with a group of people, Yuuko's sister pretended as if she was kidnapped for the sacrifice and lured Yuuko back to the school (Under the school was the shrine which could be accessed through a secret door). There they performed the ritual and threw Yuuko down to the shrine and to prevent her from escaping, they broke one of her legs and nailed the door shut. Only after the ritual did the people, including her sister, realize what they had done, but they did not repent and left her there to die. Initially only scared and sad, Yuuko began to slowly die due to lack of food, water and her leg injury. Finally in anger, she demanded that if she was a sacrifice then the gods should grant her last request which that all those related to her murder would die. Following this, all those except her sister died from the plague or insanity, seemingly in response to Yuuko's dying wish. However, the plague did not vanish after the ritual. In despair her father committed suicide and out of regret, her sister opened the door only to find Yuuko's corpse. But Yuuko's ghost then attacked her sister but could not bring herself to kill her. She ran away and in her sadness tore away that part of herself.
