Her hobbies are shopping, desserts... and killing vampires.

One day, a girl transferred to my school and stunned the class with her shocking self-introduction.
She will turn my my dull gray high school life bright red.

A unique coming-of-age love comedy between a "self-proclaimed vampire-hunting gal" and a "high school boy who lives in the shadows"!
