One day, Kaito Kotaro ( L/N Y/N) received an envelope invitation to visit Decelis Academy. There, Kotaro was welcomed by everyone in that school, because of his reputation. Specially, on that day, when a girl named ' Sooha' immediately had a crush on him, her feelings for him never died down. And from that time, everything has change in ' alternate' way, because of Kotaro's appearance. Can Kotaro manage to save Sooha away from the ' First Vampire'- ' Dardan', the one who is blindly wants everything from Sooha???? " I'm may seems like i'm dying, but i won't die." - ( Kotaro's quote)-
