Synopsis
Nazuna needs new blood for her cuddle-buddy business, and Kou is on the case! But he's not the only one wandering the night looking for someone...

Summary
Nazuna earned some money while working as a maid and decided to buy herself some stuff. As she ended up enjoying money, she decided to improve the quality of her cuddle buddy business to make it more profitable. She then sends Kou to go find her new customers. Kou then goes around looking for people who look super tired. He sees a woman smoking on a bridge, who looks super tired. He mentions that she looks super tired and wonders if she wants to chat for a bit and she agrees.

They go to a coffee shop and Kou explains that he wasn't trying to hit on her, but that disappoints her a bit as she got excited for a moment a young boy is interested in her as she was feeling quite lonely recently. Kou explains that he is looking customers for a cuddle buddy business and looking for people who are slept deprived, but explains that the cuddling is done by the business owner. Hearing that he is working part time, she cites the labor law that a person under 18 can't work in after work hours and states she can report them. Kou panics for a moment, but she tells him, she is just joking. She tells him to be more careful at who he picks and that she doesn't like cuddling, but sleeping alone. Kou mentions they are also doing massages, which interest her as she works all day. Kou wonders what she work and she gives him a business card, where he sees her name is Anko Uguisu and is a private detective, which excites him. Anko asks him if he is usually outside at this time and Kou confirms. She then asks if he knows Akihito Akiyama, however, Kou can't recognize the name. Anko then shows him a picture and states his friends call him "Akkun". Kou then recognizes him, but nervous states he doesn't know him. Anko noticed he got nervous and pulls him towards her, asking if he really don't know him. She checks his pulse and hearing his heartbeat, she lets him go. She leaves extra money for the drinks and explains that the change is for him. She tells him to call her if he hears anything about Akkun and to actually try hitting on her next time and then leaves.

Hearing what happened, Nazuna is disappointed and states she isn't interested in doing anything unless she gets some booze. Kou expected that and brought some with the money Anko gave him, which made Nazuna happy.

Mahiru calls Kou and Akira and takes them to school at night, stating he wants they to have fun together. As they jump the fence, Mahiru explains that with Kou stopping coming to school, they may not have met again. By chance they are able to meet at night and he wants to make proper fun memories between the three of them. As they enter school, Mahiru mentions the urban legend of the seven school mysteries. The most famous one is Hanako-san haunting the toilets and wants them to go and verify those mysteries. He makes Akira go in the bathroom and try summoning Hanako, and as she does, he replies in a girl voice, scaring Akira, but she hits him in return. The three then proceed and to verify the other mysteries and have fun and take pictures while doing it. After they are done, Mahiru mentions there is one more mystery of a teacher that disappeared at this school ten years ago and they say that the teacher appears at night at school, but Akira and Kou don't find the story scary.

He still convinces them to go and check it as either way they are already at the school. Upon checking the supposed classroom, they find a person standing in the middle of it. The teacher wonders why are they here at night as its dangerous. He states he was restraining himself and today was his last day, but its their fault for coming. The teacher then jumps on Akira, stating he prefers women. Mahiru tries to pull him away from Akira, while Kou stands still, wondering why is there a vampire here. He then grabs a chair and hits the teacher, pushing him away from Akira. Kou feels something is different and knows he is a vampire, but he looks so unkept and distressed. The teacher tells them to run away before he loses it. Anko then shows up, stating she was on a different trail, but still hit the jackpot. The teacher states he didn't want to run into anyone, but can't hold any longer and wants blood. Anko shows her neck and he jumps at her. She opens her arms and hugs him, letting him bite her, but a moment later, he backs off in agony, stating she taste quite bad. Anko states she couldn't find any leads on him, but now is sure that for the past ten years after he became a vampire, he never once ate properly. He restrained himself for ten years, but today was his breaking point. Kou wonders why didn't he drink blood. Anko states that no one would want to become a vampire and the vampire confirms that he was tricked. Anko tells him she will let him die as a human being and puts a silver ring in his hand, and force him to hold it and not resist. As she talks to him and calms him, the morning comes and he turns to dust.

Anko states that the teacher who went missing ten years ago died today as a human, although he was supposed to die naturally today anyway. She reintroduces herself and states she works on cases that sometimes involves missing people who went missing due to vampires. Kou wonders why she killed him, as she stated he was either way going to die today. Anko asks him if he should have lived a life as a monster. He struggled for ten years not knowing what he became. She tells Kou that he knows nothing about the vampire and won't let him achieve his idiotic dream.
