Vampires cannot be harmed 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.

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

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...

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.

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.

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.

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

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.
