The series focuses on Eiri Kurahashi, a college art student who works in an antique shop. One day, he sees the image of a girl in an antique glass. To his shock, she appears to be moving and living out her life before his eyes. He becomes infatuated with the girl, and one night at midnight, he somehow makes contact with her. He learns that her name is Cossette, and that she was an aristocrat's daughter during the 18th century. She reveals to him that her spirit has been entrapped within the glass because the artist Marcello Orlando murdered her. She tells Eiri that, in order to set her free, a man must be willing to take upon himself punishment for the sins Marcello committed. As the series progresses, Eiri is tortured mentally and physically by Cossette, who demands that he prove his professed love for her. It is revealed that Eiri is the reincarnation of Marcello, and that Cossette is becoming as infatuated with him as he is with her. Also depicted are the efforts of the women in Eiri's life—relatives, friends, mentors, and the girl who secretly loves him—to free him from what is becoming apparent to them as a self-destructive path.

Reception
Anime News Network's Theron Martin described it as "an artsy, stylish supernatural horror story about love and obsession. Its dramatic visuals, exceptional artistry, and sumptuous musical scoring make watching it quite an experience, and the story isn't half bad, either." However, he noted that the storyline of the first two episodes was "fairly predictable" and the secondary characters were "underdeveloped and underused". Reviewers at Mania Entertainment praised it as "a love story that's almost devoid of happiness, with a style and presentation that makes it engrossing, and yet not exactly easy to watch" and "an easy recommendation for those looking for something more mature from their anime."
