Titled Nyaa no Imouto-chan wa Motemote Nya (ニャーの妹ちゃんはモテモテにゃ), the episode combines several separate disasters: Yani's bathroom-related trouble, Imoko's school life and a strange application obtained by Yaku Neko that completely changes Yani's attitude toward smoking.

Episode 9 Preview and Key Visual

Episode 9 Returns After a One-Week Special

Episode 9 marks the return of the regular story after the August 27 slot was used for Kyou dake Kirei na Yanineko Tokuban instead of a new episode.

The special featured Yuko Natsuyoshi and Tetsu Inada, with Tenshin Iida serving as MC. It looked back on the anime's earlier episodes and included behind-the-scenes discussion about the production.

The official Episode 9 materials now confirm that the series is continuing with a normal episode on the September 3 schedule.

Imoko Gets More Attention at School

One of Episode 9's main threads returns to Imoko, Yani's younger sister and the far more responsible member of the family.

At school, a girl described as having a princely image secretly develops feelings for Imoko and gives her a present. In typical Yanineko fashion, however, what sounds like a straightforward romantic setup quickly becomes connected to the episode's bathroom-related comedy.

The public synopsis does not explain how Imoko responds or how far this relationship will develop, leaving that part for the full episode.

Yaku Neko's App Turns Yani Into an Anti-Smoker

Another segment focuses on Yaku Neko, who gets hold of what the official synopsis calls a common-sense alteration app.

The application radically changes Yani from a heavy smoker into someone with an extreme dislike of smoking. That immediately flips one of the character's defining traits, since cigarettes have been central to nearly every part of Yani's daily life since the beginning of the series.

One thing remains untouched: her cleanliness. The synopsis specifically jokes that the change in values does absolutely nothing to improve the way she lives.

The Preview Packs Multiple Disasters Into One Episode

The Episode 9 preview indicates that the story will move through several different comedic situations rather than one continuous scenario.

Alongside the Imoko storyline and the common-sense app, Yani's bathroom problems cause trouble both around a station and inside her apartment. The footage keeps the deliberately crude and chaotic tone that has defined the adaptation since its opening episodes.

Because the preview itself is the central new video material for this update, it also serves as the main visual source for this article.

Takashi Aoshima Scripts Episode 9

Takashi Aoshima handles the Episode 9 script, while Natsuno Momoko is credited for the storyboard. Episode direction is shared by 尋田耕輔 and Naoaki Shibuta.

Riki Matsuura and Chika Noumi are credited as chief animation directors. Matsuura also serves as the main character designer for the TV series, with Bibury Animation Studios handling overall animation production.

Across the series, Taku Kimura serves as director, Keiichi Suzuki provides the music, Wasureranneyo performs opening theme Nanmonee and Necry Talkie performs ending theme Kemuri to Blue.

Broadcast and Streaming Follow Different Schedules

TOKYO MX and BS11 air Episode 9 on September 3 at 24:30 JST, using the late-night broadcast notation common in Japanese television schedules.

Streaming through Netflix and other services begins rolling out at 25:00 JST. AT-X carries a later broadcast for Episode 9 on September 19 at 24:30 JST.

The official site also notes that selected Yanineko episodes have both a standard On-Air Version and a Jaryu Kaiho-ban, which preserves material according to the production's intended presentation. Availability differs by service and episode.

Why This Matters

1) Imoko gets another storyline outside Yani's apartment

Episode 9 gives Imoko more material at school instead of using her only as the responsible sister dealing with Yani's problems.

2) Yani's defining trait is flipped completely

Turning a heavy smoker into an extreme anti-smoker creates a premise that directly contradicts the character's core identity.

3) Regular episodes resume after the special

With no new episode on August 27, Episode 9 is the first regular installment since Episode 8.

4) The official preview provides clear video context

The new footage covers multiple Episode 9 segments, making it directly relevant for both the article and Short/Reels coverage.

Closing

Yanineko Episode 9 returns to the series' mix of everyday character interactions and absurd escalation, this time giving Imoko additional attention while forcing Yani to experience a version of herself that suddenly despises smoking.

The episode airs on TOKYO MX and BS11 on September 3 at 24:30 JST, followed by streaming from 25:00. How long Yani's altered values last and how Imoko's new admirer develops remain unanswered until the full episode arrives.
