An oddball group of friends has come together around Endo Yasuko, a beautiful high schooler who just so happens to be a vampire! Her long, unliving history is starting to catch up to her: figures from her past are popping up at school, and not all of them are friendly. With girls mysteriously vanishing in gloomy Yomai town, Yasuko will do whatever it takes to protect the one friend she cares about most: her roommate Shizue, her main food supply (and maybe her main squeeze)!
