I stumbled upon this gem on Reddit about a few hours ago and I was pretty hooked.

The story follows Yamori Kou, a run-of-the-mill nihilistic teen who stopped going to school because it was boring. He's pretty introverted in the beginning until he meets our second main character, Nanakusa Nazuna who tells Kou about the fun of "Night Walking." The two have fun throughout the night and it eventually gets to the point of Nazuna inviting Kou back to her house. Now, you might be thinking: "I've seen enough hentai to know where this is going" but no. Instead, Kou is alarmed when he sees that she sucked his blood. Surprised, she tells him that she is a vampire and that his blood tasted the best. With his newfound rebellion against sleep, Kou asks Nazuna to turn him into a vampire; the catch being you have to fall in love with the vampire that bit you to become one.

This story might sound like a cheesy run-of-the-mill romance about a vampire and a teen boy but it's really not. Each of the "arcs" are about different people encountering these two and them being taught the "art of Night Walking." It's a pretty relaxing manga all things considered, some of the characters I even wound up relating to. It's definitely a niche title, but give this one at least 5 chapters to see it's for you.

Overall: 7.5 or 8/10 - Not outstanding by any means but I will definitely read more
