Black Cat

Train Heartnet, known as the infamous assassin Black Cat, carried out his jobs with precision and disregard for human life. He worked for Chronos, a powerful organization, under the codename Black Cat in the underground world. Train's life took an unexpected turn when he met Saya Minatsuki, a bounty hunter with a unique outlook on life. Saya's positivity influenced Train, who began to question his actions and ultimately decided to leave his assassin life behind, choosing instead to become an honest bounty hunter.
