Yani Neko: Anime about a bunch of cat girl smokers

The first thing that reaches you is the smell.Not the kind that lingers in a hallway after someone has passed through with a cigarette. Something denser. Tar soaked into walls, ash ground into the floorboards, the quiet insistence of a room that has stopped pretending to be anything other than what it is. Inside that room lives a catgirl who has already decided that the next pack matters more than the rent, more than the sister waiting outside, more than the landlord who has long since stopped expecting payment on time.

Yaniko Satou — Yani Neko to anyone who has watched her long enough — moves through the days the way smoke moves through a cracked window. She is twenty-one, beastfolk in a world that still measures humans as the default, and every decision she makes folds back toward the same small orange glow, money disappears into convenience stores and Jobs end the same afternoon they begin. When the pack is gone she will pick butts from the street, from the ashtray, from places that should not be named. The apartment fills, the air thickens, she keeps breathing it in.

The manga that first carried her arrived the way certain things arrive now — not through a publisher’s desk but through the open noise of a timeline. NyanNyanFactory, a loose collective of four rotating artists who met inside a Discord server meant for gamers, began posting short strips under anonymity in late 2022. Arai Azuki, Osatou, Mikirou, Kurumizawa Taro. They did not divide labor into writer and illustrator. Each took a chapter whole, drawing and writing in rotation, chasing the same character who refused to improve. The strips were crude, relentless, oddly tender in their refusal to look away. Weekly Young Magazine noticed and serialization began in February 2023. The advance they were offered left them stunned. What had started as a private joke about a chainsmoking catgirl had become something the industry was willing to pay for at scale.

The apartment building itself begins to fill with others who have also stopped climbing. Yaku appears first as the one who still functions, the drug-using neighbor who somehow keeps jobs and still checks on the others when the nights stretch too long.

Hame is the cleanest of all but has one addiction and that is gaming and her own obsession to be a successful streamer one day.

Nishi Kaoruko speaks in thick Kansai dialect, smokes her preferred brand with a certain style, and remains desperately, hopelessly committed to making people laugh even though her comedy never quite lands.

Aruko Sakai college roommate who drifts through most days in a quiet alcoholic haze, sleeping for hours and vanishing to distant places whenever she drinks outside the apartment.

The human landlord, Ouya Otani, watches from the edge of the frame, equal parts exasperated and complicit. He could throw them out, he does not. Somewhere in the background a younger sister Satou Imoko still tries to drag Yani toward something that looks like a future, and the effort itself becomes another kind of comedy — the comedy of someone who still believes the people she loves can be salvaged.

Bibury Animation Studios took the material and refused to sand it down. Under director Taku Kimura the dirt remains dirt. Cigarette ash clings to skin, the apartment is not stylized squalor, it is the specific geometry of a life that has stopped cleaning itself. Character designer Riki Matsuura keeps the catgirl faces soft enough to register as cute while the bodies and the rooms refuse the same softness. Keiichi Suzuki’s score does not comment, it simply sits in the smoke with them.

What the series refuses to do is apologize for the characters or redeem them on a schedule. Yani will try to quit yet she will fail within the same episode. The failure is not framed as tragedy or as punchline alone, it is simply the next beat in a life that has already taught itself the shape of relapse. Around her the other beastfolk carry their own private collapses — addiction, debt, the quiet knowledge that the world outside the building was never built for them. The humor is black and physical and sometimes deliberately disgusting.

The manga’s early reception tracked the same split the anime would later inherit. Ranked high in the Next Manga Awards, noted in Kono Manga ga Sugoi, it found readers who recognized the particular exhaustion of watching someone you care about refuse to change. Others found the gross-out gags and the relentless focus on failure too much to stay with. Sales climbed past four hundred thousand. The collective kept rotating chapters. The updates stayed frequent even as the artists’ own lives shifted around the work. One of them, having quit smoking years earlier, found the habit returning while drawing Yani’s constant need. The fiction and the makers began to blur in ways the series never bothers to hide.

There is a moment, early and ordinary, when Yani sits on the floor of her room with the last cigarette and the knowledge that there will not be another until someone gives her money or she finds a way to steal it. The camera does not rise, the music does not swell, she lights it, the smoke rises outside the window , the ordinary city continues without her. The series never claims that this is resistance or poetry, it only claims that this is what the day looks like when the only reliable thing left is the next drag.

NyanNyanFactory has not yet scattered into a wide catalogue of separate titles. Their energy remains concentrated inside this one ongoing apartment. Individual members have begun other projects — a zombie comedy, erotic one-shots, contributions to anthologies — but the factory itself still returns, week after week, to the same stained walls and the same catgirl who will not stop smoking. The anime, still airing, keeps faith with that concentration. It does not expand the world so much as deepen the texture of the rooms already known.

It is the ordinary courage of continuing to watch someone who has already decided that recovery is not the point. The smoke keeps rising, the landlord keeps waiting, the sister keeps trying and somewhere inside the mess a catgirl lights another one, as if the act itself were the only story left that still belongs entirely to her.
