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.
