Call of the Night. Volume 3: Kotoyama

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...

Nazuna isn't the only one who thinks Ko is a delicious snack. And Ko isn't the only one who gets jealous. When Ko draws the attention of four other vampire girls with nefarious intentions, he must fight for his life-even though he wants to give it up to become a vampire. But only to a certain special someone. Unfortunately, there's a time limit on being "turned," which raises the...uh...stakes. Then, Ko follows some dating advice that backfires. Undeterred, he tries to help another vampire and mortal mend their love/hate relationship.
