Main characters at a glance

Yanineko is the main character in Chainsmoker Cat. The official profile lists the Japanese name 佐藤ヤニ子, age 21, and Yuko Natsuyoshi as the Japanese voice actor.

Yakuneko is listed as 越司丸益子, age 20, and is voiced by Misato Matsuoka. Imoko and Landlord Otani connect Episode 1 to family and rent, while Yakuneko widens the cast in Episode 2.

The cast reference below keeps the official Japanese identity beside the alias, age when published, species, credited performer, first appearance, and profile link.

Official Japanese names and English search spellings

The anime site publishes the character aliases and Japanese personal names. English renderings on this site help readers connect those official profiles with English-language searches, but they are not labelled as licensed spellings without a publisher or service source.

This distinction matters most for Yakuneko. The official profile gives 越司丸益子; Yakuko Etsushimaru remains visible as a historical URL and search spelling rather than an official English full name.

Yanineko follows the same evidence order: 佐藤ヤニ子 is the official Japanese personal name, while Yaniko Sato is the English rendering used in page titles and search context.

Open the Yakuneko character and voice actor profile for the full name note and Episode 2 context.

How the ensemble creates the comedy

Family concern, unpaid rent, streaming culture, manga deadlines, drinking, and bad advice give each character a different source of pressure.

The relationships are more useful than a flat name list: Yanineko and Imoko are sisters, Otani is the landlord who has to enforce the building rules, and Yakuneko looks to Yanineko as a senior despite Yanineko's poor judgment.

Episode guides connect those traits to the scenes where the relationships become important, while individual profiles stay focused on the character rather than repeating a full episode recap.

Begin with the Episode 1 recap or continue to the Episode 2 guide for Yakuneko's introduction.

Japanese voice cast

Yuko Natsuyoshi voices Yanineko (佐藤ヤニ子), and Misato Matsuoka voices Yakuneko (越司丸益子). The official cast page also credits Yurie Funato, Ayaka Shimizu, Shiori Izawa, Rina Honnizumi, Riko Akechi, and Tetsu Inada.

Use the individual links in the cast table when you want the role behind a name. This avoids treating a changing database profile or fan-posted list as the source for current credits.

Read more about the lead credit on the Yuko Natsuyoshi voice actor page.

Find the character behind the name

Searches for this cast can use an alias, a Japanese personal name, or an English rendering. The official anime profiles are the reference for the Japanese aliases and personal names, while the English spellings on this guide help connect those pages to the ways English-speaking readers look for them.

For the lead, Yanineko is the character alias and 佐藤ヤニ子 is the official Japanese personal name. Yaniko Sato is an English rendering used on this site. For her junior, Yakuneko is the alias and 越司丸益子 is the official Japanese personal name; Yakuko Etsushimaru remains visible only as a historical URL and search spelling.

This page keeps the names next to the credited performer so a reader can move from a search spelling to an official identity without treating an unlicensed romanization as a confirmed English release name. The character profiles explain those distinctions in more detail where they matter.

Use the Yanineko profile for Episode 1 context, or the Yakuneko profile for the Episode 2 name note.

Choose the right cast page for your question

Start here when the question is broad: who the main characters are, which Japanese actor voices a role, or when a character first appears. The reference list and voice-cast matrix give the fastest route across the full eight-character group.

Open an individual profile when the question is about one person: Yanineko's family and apartment pressures, Yakuneko's Episode 2 introduction, or the official name attached to a particular alias. Those profiles keep the facts close to their story context instead of burying them in a long list.

Use the episode guides when the goal is to avoid spoilers. Episode 1 introduces Yanineko, Imoko, and Landlord Otani; Episode 2 adds Yakuneko and the group around her. This route lets a new viewer identify the cast without jumping ahead of the broadcast order.

Follow the Chainsmoker Cat episode guide for the story-order route.

A spoiler-light way to learn the cast

Start with Yanineko, Imoko, and Landlord Otani if you have only seen Episode 1. Their pages explain the family and apartment relationships without requiring Episode 2 details.

After Episode 2, move to Yakuneko, Hameneko, Kansaineko, and Aruneko. Each profile keeps the official Japanese name, performer, and first appearance close to the story context.

When the official profile leaves part of a character's history unclear, the page preserves that limit instead of turning a theory into a biographical fact.

Use the episode guide to stop at the episode you have already watched.

Use the cast reference for the question you actually have

Use the cast reference when you need to match a name in a search result, a credit, or an episode discussion with the same person on the official anime site. The alias is usually the quickest label to recognize, while the Japanese personal name and credited performer make the match more precise when several spellings appear together.

When a search result gives only a performer name, use the full table to match that credit with the alias and official Japanese name before opening a profile. That keeps a voice-actor search from being mistaken for a separate character page.

Choose the Yanineko profile for the lead's official identity, Episode 1 setting, and Japanese voice credit. Choose the Yakuneko profile when the question begins with 越司丸益子, Yakuko Etsushimaru, or her Episode 2 introduction. The individual pages add context that a cast list should not repeat for every name.

Use the episode guide when the first-appearance field matters more than biography. It keeps the early cast in broadcast order, then points toward the wider group after Episode 2. That route helps a new viewer identify a character without reading ahead through a later profile or treating a search spelling as a separate person.

Continue with the episode guide when you want the character order before a detailed profile.

Supporting characters and additional cast

The eight official character profiles remain the core reference. Recent anime episodes also identify supporting roles including Penpen Neko, Sato Shizue, Nishi Shunran, and Jikaki Neko / Kaku Eiko.

Penpen Neko is connected with the Episodes 6–7 housing storyline, Sato Shizue is identified as Yanineko and Imoko's mother in Episode 7, and Nishi Shunran is Kansaineko's younger brother with an earlier anime appearance and a larger role in Episode 8.

Episode 10's eyecatch artist Ai Kago also confirms voice-performance participation, but the official announcement does not identify her role. Episode 11's eyecatch was created by Necry Talkie.

The compact supporting-cast reference above keeps these names and credits together without presenting them as replacements for the eight core profiles. Episode pages list additional credits where they are relevant.
