A retail guide for Japanese bookstores lists a planned anime adaptation for the Itsuka Tenma no Kuro Usagi light novel series by Takaya Kagami (The Legend of the Legendary Heroes/DenYūDen). The "reverse school fantasy" follows an ordinary high school boy named Taito Kurogane who is given a "poison" by a female vampire named Saitohimea, thus changing his life.
