Servamp, Vol. 1

A Vampire Cat Serves Only One Master\
\
When a stray black cat named Kuro crosses Shirota Mahiru's path, the high school freshman's life will never be the same again. Kuro is, in fact, no ordinary feline, but a servamp: a servant vampire. While Mahiru's personal philosophy is laissez-faire, he soon becomes embroiled in an ancient, altogether surreal war between vampires and humans.
