Synopsis

A young man picked up a vampire girl who collapsed in the street. Although she tries to serve him wholeheartedly to repay him for his blood, she is too clumsy to succeed. A warm slife-of-life interspecies vampire comedy where nobody is left behind or abandoned! (Source: Shueisha, translated)
