Chanto Suenai Kyuuketsuki-chan

Chanto Suenai Kyuuketsuki-chan introduces Luna Ishikawa, a vampire transfer student whose cool, almost intimidating presence quickly makes her the center of attention in class. To Tatsuta Ootori, an ordinary boy who expects to stay far from that kind of spotlight, Luna seems like someone he would never have reason to talk to. That changes when the two are unexpectedly assigned to cleaning duty together, forcing them into close contact and revealing a side of Luna that few people get to see. Beneath her composed exterior, Luna is not the perfectly collected girl her classmates imagine: she is a vampire who cannot even suck blood properly. Tatsuta, wanting to help her overcome that weakness, volunteers to become her practice partner. What begins as a small act of support soon grows into an easy friendship that brightens their mundane school days. As Luna keeps trying bite after bite, the pair work toward her delectable goal and slowly turn an awkward secret into a bond built on patience, trust, and daily progress.
