It gets under your skin sideways. There's no spectacle here, no chase, just a private detective pulling on a thread until the thread turns out to be a noose: the green cat everyone treats as a lucky charm is quietly ruining every life it touches. That inversion is the whole trick, and it's a strange one even by Tezuka's standards, which is saying something. Nobody in it is a person so much as a piece the story moves, and the plot leaks in a couple of places if you press it, but at one episode you're in and out before that matters. This is Lion Books material, Tezuka in his cold, short-form mode where the moral lands like a slap and then the credits roll. Watch it for the pedigree, stay for the sick little idea that good fortune might just be misfortune with better timing.
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.
