Call of the Night

A new night begins as the other vampires offer to help Ko and Nazuna with their relationship. But what they really want, however, are the deets.

Ko's alarm bells go off when he meets Mahiru's new friend. Mahiru may not know what Kiku is, but Ko does.

A tense confrontation with Anko reveals an alarming secret: vampires have a weakness they didn't know about. Now, they all must decide their next move.

Some patients say Room 307 is haunted, and Kabura warns Ko and Nazuna to stay away. Something's in that forbidden room. Something that might hold the key to the past.

Kabura thought she'd be with Haru forever. But life never goes according to plan, even for vampires. Now Kabura is left with a burden she never asked for.

With Anko closing in, the vampires must destroy the source of their weakness before she can find them. Midori's search leads Ko and Nazuna to someone... unexpected.

When Ko finds the diary of a girl called Kyoko, he discovers that he wasn't Nazuna's first human friend. Nor the first person she ever considered turning...

What began as Kyoko and Nazuna's investigation into a supposed affair led to a life-changing event that altered their relationship forever.

Vampires cannot be killed by conventional means, so what does Anko hope to accomplish by shooting them out in the open? Ko suspects there's a method to her madness.

As the battle between vampire and hunter erupts, Ko finally realizes the full scope of what's at stake. Now he must stop both Anko and Nazuna before it's too late.

Something's wrong. Or maybe too right. Ko isn't a vampire, so why does it feel like his body's ignoring the rules? He and Nazuna need answers.

Growing up doesn't guarantee answers to life. As Ko wonders what it means to be ordinary, he and Nazuna venture through the city. Where will the night take them this time?
