Hayato Takenaka

When Kanzaki receives a letter from Mari Setogaya asking to meet in their school's PE storage room during the lunch break, he believes he will be receiving a love confession. He turns up eagerly, only to be attacked by his supposed admirer. The beautiful girl tries to knock him unconscious, but when she fails miserably, she explains that she is a vampire and had wanted to feed on him. Feeling pity for her hopeless state, Kanzaki reluctantly yields and allows her to drink his blood. As it turns out, Mari cannot stand the taste of raw blood but will perish without the nutrients it contains. Kanzaki is quick to find a solution, offering her a different bodily fluid to consume—and Setogaya instantly falls head over heels with this new flavor. The two soon start meeting regularly, and as time goes by, their relationship evolves into something more than just casual "meals" spent together. (Source: MyAnimeList)

A series of short stories, based on the erotic manga by Emily, involving high school students and their love lives.

Independent stories based on the adult manga by Toruneko. The first episode is about the boobs of a popular girl in school. The second takes place in a houshold with two siblings.

When Kanzaki gets his first love note from a cute girl in another class, he's not sure what will happen. But the last thing he expects when he goes to meet his admirer is to get kicked in the face before he even says hello. It turns out that his admirer, Mari Setagoya, is a vampire and not a very good one, at that. After knocking Kanzaki out and trying to suck up his blood Mari admits that she can't handle the raw taste of blood very well. But she needs to drink life energy to survive, and one bodily fluid is as good as the next when it comes down to it. Kanzaki is all-too willing to oblige, but Mari has another secret. Along with a thirst for life energy and impressive leathery wings, Mari has another special ability, one which is about to awaken thanks to Kanzaki.
