Call of the Night, Vol. 12

Antisocial, dorky boy seeks fun-loving, sexy vampire for blood-sucking and transforming into her minion.
One sleepless night, Ko slips out to walk the streets. Life after dark is a revelation!
Especially when he meets flirtatious Nazuna. Except that she’s a vampire. That’s okay.
He wants to become a creature of the night too. But transformation doesn’t come that easily…
Our human friends are attacked by a mysterious male vampire. Luckily—or unluckily, depending on your point of view—Ko’s half-vampire mode is growing ever more powerful. Who turned the attacker, and what is he after? No sooner are these questions answered than new ones arise as a second attacker arrives on the scene—and she’s targeting both humans and vampires!
