In a city where humans and cat-people coexist but never in harmony, Alba Rose hides his true identity as a cat-person while working as a bartender. He was once a serial killer, a life he abandoned with the support of his fellow cats and the affection of an orphan girl named Nico, who lives with him. Together, they have built a quiet, peaceful existence. But when a new serial killer who targets cats begins to stalk the streets, the city is gripped by fear. This killer, known simply as the Nightwalker, forces Alba to confront the past he thought he had buried. As he investigates, Alba learns that the Nightwalker is responsible for the murder of his close friend Teabird. Driven by grief and a desire for justice, Alba delves deeper into the mystery. His search leads him to a mysterious circus and its host, Francesca, who reveals that Alba himself has a profound connection to the Nightwalker. The truth eventually circles back to his foster father, Ziggy, forcing Alba to reckon with the people who shaped him and the violent history he can no longer outrun. The story unfolds across three volumes of gothic, melancholic fantasy, charting Alba’s struggle between his desire for redemption and the inescapable pull of his darker nature.
