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

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.

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.

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.

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.

Boredom drove Ko into the night. Boredom drove Ko’s new acquaintance to killing time in her own way. She and Ko seem very similar… perhaps TOO similar for comfort.

Nazuna needs new blood for her cuddle-buddy business, and Ko is on the case! But he’s not the only one wandering the night looking for someone…

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...

The night feels distant. Ko isn’t sure how to close that gap.

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

When can you start calling someone a friend? What even IS friendship, anyway? As Ko reconnects with a classmate, questions arise he isn’t sure he knows how to answer.

Seri is extremely popular, but popularity isn’t all it’s cracked up to be when one of her human paramours develops feelings she isn’t ready to deal with.

What does it mean to be a vampire? Why does Ko want to become one? A chat with a friend reveals Ko’s lack of answers to these all-important questions.

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.

Three’s a crowd when Ko invites Akira to hang out with him and Nazuna late one evening.

A chance encounter with a stranger introduces Ko to a nocturnal life. Ko follows her and why shouldn’t he? The night is still young.

How can you fall in love with a vampire when you can’t even track them down!? Nazuma remains frustratingly elusive, but Ko may have a nostalgic solution to this new problem.

Ko doesn’t need a mirror to see his reflection. It’s staring right back at him in the form of Nazuna’s latest client.

How does Nazuna make money, anyway? Ko is about to get the inside scoop on her (very suspicious) business, but first he’ll need to make sense of his complicated emotions.

Ko thought he had all the time in the world, but the revelation of an unexpected deadline changes everything. Hopefully his friends (new and old alike) will have some advice.

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.

It’s not all sparkles and hearts at the maid café where Midori works. Someone is creeping on a certain maid, but uncovering the interloper isn’t as easy as it looks…
