Call of the Night Vol. 4
Nazuna can't let her guard down for a second now that a flock of hot vampire chicks are interested in Ko's hot blood! And when she takes a shift at a maid café where the customer is always right, it turns out the vampire is always wrong. Meanwhile, Akira meets the girl Ko rejected before meeting Nazuna, and Ko meets a private detective searching for someone he knows. Then, a late-night visit to Ko's school to ghostbust spooky legends leads to a new perspective on giving up your humanity...
