Chanto Suenai Kyuuketsuki-chan

Luna Ishikawa arrives at school with all the cool mystery expected of a vampire and quickly becomes the center of attention. Tatsuta Ootori, an ordinary classmate who assumes she is far beyond his reach, barely expects to speak with her. A shared cleaning assignment changes that when he discovers the secret behind Luna's carefully composed image: she is terrible at drinking blood.

Instead of laughing, Tatsuta offers to become her practice partner. Failed attempts and a growing supply of bandages gradually strip away Luna's intimidating facade, revealing someone shy, clumsy, and far less confident than everyone imagines. Their unusual training turns mundane school days into a gentle friendship in which Luna can finally stop pretending to be flawless.
