The Finale Goes Out Swinging
The promotional materials went out on the day of broadcast. Japanese anime news site Otaku Souken published advance stills, a synopsis and an online trailer for episode 12 on September 24, confirming that this is where the run stops.
The synopsis reads like a list of small disasters. A serialization gets axed, someone gets fired, and there's an unreasonable hole-digging part-time job. The residents of the apartment building hit their limits one after another. A battered Yani-neko finally turns on the building's unbothered landlord, and the fight escalates until microwaves are flying in what the official text bills as the largest brawl in the apartment's history. The same text then admits that the people who wrote it aren't entirely sure what they're describing.
The episode is titled "Nyā wa Saishūkai demo Yani o Suu nya," roughly "Even in the final episode, I'm still smoking, nya." Series scriptwriter Takashi Aoshima wrote the finale, and director Taku Kimura drew the storyboard.
The preview copy attached to the stills stays in character: everyone is way too stressed out, nothing much happens, but everyone is still alive, so let's call that good enough.
A Viral Comic That Made It to Twelve Episodes
Chainsmoker Cat (ヤニねこ) takes place in a world where humans and beastfolk live side by side. Yani-neko is a beastfolk who smokes constantly and does very little else. The official description runs through her qualifications: no money, no life skills, nothing redeeming, and manners she threw out along with the cigarette butts. The series follows her and the deadbeat cats orbiting her through days that are grubby and, by its own account, faintly encouraging.
NyanNyan Factory's manga went viral on social media before Kodansha's Weekly Young Magazine picked it up, and the anime's promotional copy treats the adaptation as a stunt it might not get away with. The official work summary includes an apology in advance in case the show can't be broadcast.
That apology was not purely a bit. BS11 carried an edited version of the series while AT-X ran it uncensored, so which cut viewers got depended on the channel.
Bibury Animation Studios produced the series, with Taku Kimura of Studio Lemon directing, Riki Matsuura on character design and Keiichi Suzuki writing the music. Yūko Natsuyoshi voices Yani-neko, Misato Matsuoka plays Yaku-neko, Rina Honnizumi voices Imoko, and Tetsu Inada is the landlord on the receiving end of the finale's flying appliances. Shiori Izawa, Yurie Funato, Ayaka Shimizu and Riko Akechi round out the apartment's residents.
For a series built on a cat who cannot quit smoking, twelve broadcast episodes plus a steady drip of mini-anime shorts on the official YouTube channel is a reasonable haul.
Looking Ahead
Netflix has been streaming Chainsmoker Cat in select countries and territories since the July premiere, and the series also streams via OceanVeil, so the finale is reachable outside Japan rather than locked to the TOKYO MX broadcast.
English readers have the source material too. Seven Seas Entertainment publishes the manga in English, with the first volume out in December 2025, and NyanNyan Factory's original is still running in Weekly Young Magazine. The manga has more story left than the anime adapted.
The Otaku Souken report covers the finale and nothing beyond it. No continuation has been announced.
