SerVamp Vol.3 English Version Manga

School’s out for the summer, but fifteen-year-old Shirota Mahiru has no time to kick back. Not while the clock is ticking on the verge of a Servamp war! He and Kuro have more questions than answers, especially about the secret group known as C3. But one thing is dead certain: the evil Tsubaki is still a homicidal monster with Shirota and Kuro in his sights.
