Because supernatural adolescents are staple features of manga and anime, it’s unlikely that the new Fuji TV drama series, “Koishite Akuma” (“The Loving Demon”; Tues., 10 p.m.), was directly inspired by the worldwide success of the teen vampire saga, “Twilight,” but that success certainly won’t hurt its chances.
Ruka (Hey! Say! Jump’s Yuma Nakayama) has yet to mature into a full-fledged vampire. His canines have yet to fully develop, which means he still hasn’t tasted human blood — or, at least, human blood that he’s drawn himself. In order to get him prepared, he is cast down into the world of humans, where he boards with Jiro (Shiro Ito), the owner of a Chinese restaurant, and enrolls in high school.
