As a nocturnal being, Luna Ishikawa stands out as exceptional transfer pupil. Her composed air has instantly made her the focal point of the class. Ordinarily, it would be almost impossible for Tatsuta Ootori—a ordinary student—to ever get close to her. Yet this shifts when the pair are randomly assigned to a cleaning shift!
When Tatsuta abruptly befriends Luna, his view of her slowly dissolves: she isn"t the enigmatic, poised figure everyone imagines. In reality, she can barely drain blood correctly! Determined to aid her in mastering the skill, Tatsuta offers to become her training partner. Injecting excitement into their ordinary school routine, during late-night study sessions, in the quiet corridors, the pair steadily pursue a tasty objective, honing Luna"s blood-draining technique with each bite over time as they practice.
