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 Nanakusa。 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 he 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。
