Karin is a reverse vampire - instead of sucking blood, she injects it into her victims and fills them with vitality! Concerned about who will protect Karin when she awakens as a full vampire, Anju collaborates with renegade vampire Noel to test Kenta's loyalty. Noel bites Kenta, draining him temporarily of his usual responsible, dedicated, and hardworking tendencies. While she's at it, she hypnotizes him and instills in him the idea that vampires are humans' enemies - including Karin! Suddenly, Kenta's behavior towards Karin changes dramatically, and the hapless blood-increasing vampire has no idea what's come over her sweetheart. To complicate matters, a cute college girl researching vampires has joined the waitstaff roster at Julien and is pumping Kenta for information about possible Vampiric activity in Shiihaba.
