Tsukuyomi: Moon Phase

Freelance photographer Kouhei Morioka heads to a castle in Germany to capture evidence of paranormal activity for Hiromi Anzai, an occult magazine editor. Inside, he encounters Hazuki, a strange young girl in a white dress with cat ears who quickly fixates on him—only to reveal her true nature as a vampire, biting him in an attempt to make him her obedient servant.

To Hazuki’s surprise, Kouhei isn’t controlled by the bite. Desperate to get away from the castle and her possessive butler, Vigo, she coerces Kouhei into helping her escape, aided by his exorcist cousin Seiji Midou. Hazuki soon makes her way to Japan to search for her mother, and Kouhei finds her unexpectedly living in his home, leaving him little choice but to let her stay. As Hazuki tries to carve out her freedom, other vampires begin tracking her down.
