Maybe I add a flashback , lady nagant on a rooftop Shooting some criminals, then in the rooftop appears keiko wearing black pants, boots, a red hoodie, his hair loose and sunglasses, she shoot him but he catches the bullet with his hand, that scared her, she’s about to fall but he catches her and , she ask why he saved her, and he said that he could feel it, the fear, the hatred, she is not a bad person.
And he disappears
