Angel is a professional assassin navigating morally gray operations, executing targets regardless of guilt or innocence. She employs pragmatic efficiency, sparing individuals like Nami Kumagai upon Yuu Asakura’s request while utilizing memory-erasing drugs to obstruct police investigations. Her decisions catalyze pivotal narrative shifts, notably accelerating Yuu’s moral descent through manipulative suggestions, such as urging him to assault Nami following her father’s assassination. She wields a silenced Beretta 92FS and a Beretta 84, deploying both in critical confrontations and assassination attempts. Her adversarial clashes with Masaki Ichihara—a rival hitman influenced by a cursed firearm—escalate into mutual annihilation when Yuu alerts authorities. Angel’s role fluctuates across branching narratives, with alternate routes omitting her presence or altering her involvement. Certain endings depict her missions persisting through new assassination tapes, perpetuating an unending cycle of violence. Her design incorporates a translucent brown stocking and a cleavage-revealing crop top, aligning with visual motifs symbolic of her profession. Her past prior to becoming an assassin remains undisclosed, with no personal history beyond her professional engagements within the story’s events.
