A private detective chases a rumor: a green cat brings luck until it doesn't, until everyone it touches falls apart. The mystery unfolds in quiet dread, the kind that builds not through spectacle but through what the detective discovers about the people around him. Tezuka takes a simple premise and finds something genuinely unsettling in it, the way only a master can with a single episode.
A private detective receives an unusual case: a brilliant green cat has appeared in the city, and everyone who encounters it believes they've stumbled upon a stroke of fortune. But luck, it seems, comes with a price. One by one, those who cross paths with the creature find their lives unraveling in unexpected ways. What begins as a curious investigation into the cat's origins becomes a race to understand the curse attached to its arrival. The detective must piece together fragmented accounts and contradictory testimonies to determine whether the cat itself is the source of the misfortune or merely a symptom of something darker. The atmosphere grows increasingly tense as the mystery deepens, blending noir sensibilities with an unsettling supernatural dread. Each lead raises more questions than answers, and the detective realizes that some mysteries resist simple explanation. This compact mystery rewards viewers who enjoy stories where the answer matters less than the journey of discovery itself, where seemingly lucky encounters hide malevolent truths beneath their surface.
