Transfer student Monami has a secret and a past that has caught up with Mizushima. Deceiving Mizushima into eating a token gift of chocolate, laced with her blood, he is then catapulted into Monami's vampire world of blood, death and love. Jilted girlfriend Keiko has other ideas. With a sudden twist of fate, she is then transformed into the hideous and unforgiving Frankenstein Girl, and the battle for Mizushima's heart begins. 

"Anyone that doesn't like this film is probably the kind of person that stalks old women and kills their grandchildren. Vampire Girl vs. Frankenstein Girl is as insane as you would expect from such a title. It's up there in the camp charm factor with Yo-Yo Girl Cop, Oneechanbara, and Machine Girl. Does it make sense? Hardly, but after the opening scene of faces unravelling/pulled off, and arm swords made from blood, you'll know if this is your bag. From over-the-top satirical attacks on class cliques, to nonsensical fight sequences, this film has all the mad charm you could want. Not to mention, the kind of action sequences that many people would imagine in their heads, and then discard after they thought long and hard about them. Here, the director obviously went with their first instinct. It's fun. Very fun."
