The film is set in a typical Tokyo High School following the story of a perpetually teenage vampire named Monami (Yukie Kawamura) who falls for her classmate, Mizushima (Takumi Saito), who happens to already be the reluctant boyfriend to the vice- principal/science professor's daughter, Keiko (Eri Otoguro). The ensuring love triangle leads Monami to seek the assistance of her father who, unbeknown to his daughter, moonlights as a Kabuki-clad mad scientist with the school nurse as his assistant. The pair experiment on students in the school basement hoping to discover the secret of galvanising corpses (akin to the work of Victor Frankenstein). Their hopes are answered when they discover a solution of Monami's blood holds the properties to bring life to dead body parts and inanimate objects. The story begins to unfold after Mizushima carelessly accepts a honmei choco spiked with Monami's blood, causing him to become a vampire as well. When Keiko discovers their secret, she attacks Monami but accidentally throws herself off the school roof in the process. Her premature death leads to her father using the blood solution to transform her into a vicious Frankenstein's monster. From then on Monami and Keiko battle each other in the pursuit of winning Mizushima's heart, regardless of his feelings towards either of them.
