Ethan Baek Matsumoto/Partners in Punishment.

Hanna Akamatsu is a beautiful and elegant 17-year-old girl with long purple hair and pink eyes that turn red when her psychopathic personality takes over. The daughter of a scientist who used her as an experiment to "create a perfect psychopath," she developed two personalities: one sweet and gentle, the other sadistic, lethal, and remorseless. After years of injections and torture, Hanna killed her own father in the final application and, thanks to the experiments, gained superhuman strength, resistance to poisons, and an altered sense of taste that only perceives sweetness, making her an excellent cook but terrible at measuring spice. Expelled from Korea and transformed into a dangerous legend, she is adopted by Lee Matsumoto, who lost her daughter Hyena to bullying. Moved by the story, Hanna fully embraces the Divine Punishment plan and begins to use her princess-like appearance and psychopathic persona to execute carefully planned revenge against each aggressor in the name of Hyena's memory.

Name: Ethan Baek Matsumoto Age: 25 years Appearance: Ethan has a defined physique and impeccable posture. He has straight, slightly messy silver/white hair falling over his forehead, and intense, sharp eyes that convey constant alertness. He dresses versatilely: he can appear in a blood-stained suit, fitted dress shirt, and holsters when on a mission, or in dark casual clothes, a cap, and discreet accessories (chains, rings, earrings) when he needs to blend into the crowd, reinforcing his talent for disguises. His serious, almost expressionless face only softens slightly when the subject involves his "father" or the memory of his dead sister. History and role in the organization: As a child, Ethan was just an abandoned boy on the streets, used as bait and shield in dirty jobs for local criminals. In one of these situations, he was saved by Lee Matsumoto, the big boss of the global corporation. Instead of handing him over to the authorities, Lee took him home, trained him, and officially adopted him, destined to be his daughter's personal bodyguard and, later, his right-hand man in the company and behind the scenes of the underworld. Ethan grew up alongside the girl, protecting her from the shadows, but without realizing how much she suffered bullying at school because the girl herself hid everything so as not to worry her father. When Lee's daughter commits suicide after years of abuse, Ethan is consumed by guilt: he believes he failed in his only true mission, to protect his "sister." Therefore, he unhesitatingly embraces Lee's plan of Divine Punishment by adopting Hanna, the psychopathic assassin identical to his dead daughter. Today, Ethan coordinates operations, prepares false identities, gathers information on each abuser, and becomes Hanna's direct partner, living with her and pretending to be her boyfriend in public. Protective, shrewd, extremely cautious, and deadly in hand-to-hand combat and with weapons, Ethan sees revenge not only as justice for his father and sister, but as the only way to one day forgive himself.
