Chainsmoker Cat: Japanese Fans Decide the Little Sister Is Just as Codependent

Chainsmoker Cat: Japanese Fans Decide the Little Sister Is Just as Codependent

Chainsmoker Cat's official channel posted a short scene where the protagonist's little sister, Imouko, tells her "Honestly, you really can't do without me" — with a smile — and 590 comments later, Japanese fans have decided that smile confirms she's just as dependency-wired as her chain-smoking sister. The second-highest comment (4,258 likes) names the joke outright: one sister addicted to cigarettes, one sister addicted to the sister. From there the thread splits over whether that smile is sweet or a little unsettling, with some commenters digging up a manga chapter title to argue her type is settled either way. A few disagree entirely, arguing she's actually the one who ends up getting hurt.

Chainsmoker Cat's official channel posted a short clip titled “Honestly, you really can't do without me” — the little sister, Imouko, delivering that exact line with a smile. 590 comments in, the thread has decided that smile means something, and it's not subtle about saying so.

A no-good big sister who's addicted to cigarettes, and a little sister who's addicted to the no-good big sister...

タバコに依存するダメな姉と ダメな姉に依存する妹か…

That's the second-highest comment on the video, and it names the joke everyone's been circling: this show already has one character defined by an addiction. The comment section decided in real time that it now has two.

'A no-good big sister addicted to cigarettes, and a little sister addicted to (the no-good big sister)...' So the little sister is a Yani Neko too, meow!!

From there some viewers pushed the theory to its logical extreme, arguing the little sister's whole dating life is basically doomed by the same wiring.

If you're just going to end up with some chain-smoking loser who reminds you of your sister anyway, you might as well stay in love with your actual sister.

Others read the smile itself as the real evidence — not codependency by accident, but something closer to a role she's chosen and enjoys.

A quietly unhinged person who gets a superiority high from playing 'the kind little sister who looks after her useless big sister.'

That reading is also where the thread's actual disagreement starts, and it's the one real fork in an otherwise unanimous comment section. Is the smile at the end of the scene warm, or is it a warning sign nobody in the show is going to acknowledge out loud?

Whether you read that final smile as heartwarming or unsettling is probably going to split people down the middle.

I think that last smirk was completely unconscious on her part.

A few commenters went digging in the source manga for a verdict, and came back with what they're treating as a confirmed reading of her character.

'Honestly, you really can't do without me' — then that smile. → Confirmed: the little sister has a thing for hopeless people.

私がいなきゃダメなんだからからのニコッ →妹子がダメ人間好きであることが確定している

Unfortunately, the chapter where she turns someone down is literally titled 'Oh, it's not that I have a thing for hopeless guys, okay?' in the source material — so it's basically confirmed she isn't into hopeless men in general, she's specifically in love with her sister.

残念なことに振った回は原作では「あっ、ダメンズ好きってわけじゃないよ?」というタイトルなのでダメ人間ではなく姉が好きであることが大確定している

Not everyone buys the manipulator read, though. A reply pushes back with a very different theory about where this little sister actually ends up.

This little sister is the type to keep a hopeless man, tame him until he can't survive without her, and then dump him...

妹子ちゃんは、ヒモを飼って飼い慣らして自分無しでは生きられなくしてから捨てるタイプだ……

I don't know, I don't know — I think it's actually the other way around. She's the one who gets dumped. The hopelessly unlucky type who keeps drawing the short straw.

Off to the side of the whole codependency debate, a few comments just admit the show's signature meow effect got them, one way or another — proof the series can still land a joke on pure sound design alone.

  • The cat-crying voice acting is too good — it's identical to a cat in heat yowling in someone's yard.👍987
  • That Yani Neko cry made my actual cat react for real! This voice actor's performance is the real deal.👍207
  • I've said this before, but Yani Neko's voice has a real Jibanyan energy to it.👍52

And then there's the video's single most-liked comment, which doesn't bother explaining itself at all.

Went straight from what looked like a romance scene into hearing that Yani Neko voice, and just felt despair.

Nobody in the replies asks what exactly triggered that particular reaction — everyone already knows. By the time the thread settles, the running joke isn't really about the little sister anymore. It's the realization that this show can plant its own punchline in anyone, sister or not, the second they start acting a little too understanding.

FAQ

What does the clip actually show?
The official Chainsmoker Cat channel posted a short scene where the protagonist's little sister, Imouko, tells her sister "Honestly, you really can't do without me" with a smile. It drew 590 comments, most focused on what that smile implies about her character.
Why do fans think the little sister is also a "Yani Neko"?
The joke, led by the video's second-highest comment (4,258 likes), is that the show already has one character defined by an addiction (her chain-smoking sister) — and this scene suggests the little sister's attachment to caretaking her sister is its own kind of dependency.
Is there actually a disagreement in the comments, or does everyone agree?
There's a real split. Some, like @わさ-u6q and @しゃもじ-b9b, argue the smile confirms she's drawn to hopeless people (citing a manga chapter title as evidence). Others, like @RX-惑丸, push back and argue she's actually the type who ends up abandoned, not the manipulator.
