Luna Knight

High school student Luna Amano can barely remember the past five years of her life. Her older sister promised to help her build new memories, but one day, she disappeared. Left with only a few memories to hold on to, Luna devotes herself to running her sister’s flower shop, hoping that she will someday return. Then, after receiving threats from their yakuza landlord, Luna comes home one day to find the shop engulfed in flames. At that moment, everything changes, and long-buried memories begin to rush back. In an instant, Luna goes from seeing red to painting the streets red with blood. She does not know why she is so skilled with a gun, but she knows one thing for certain: she will never forgive the men who set the fire.
