Luna Knight

Luna Amano, a high school student, has no memory of the past five years. Her older sister had pledged to help her create new memories, but disappeared without explanation. Left alone, Luna manages the family flower shop, hoping her sister will return. When her yakuza landlord threatens her, she comes home to find the shop destroyed by fire. The incident triggers fragmented memories, and in an instant, Luna transforms from a passive observer to someone capable of lethal violence. She wields a gun with skill she cannot explain and becomes determined to seek vengeance against those responsible for the fire.
