Based on a manga series by Mayu Shinjo.
Due to the popularity of the anime, a real live group called Lucifer was formed. The members of this group took the names of the anime's characters, except for the lead singer, who called himself Makoto. They released several CDs & singles, as well as a concert DVD, before breaking up around 2003.
Sakuya is only half Japanese so he has blue eyes.
The series was never released on DVD in Japan and is only on VHS.
