What is the plot?

At the school, Lilysa learns that she is the only student in her class failing every subject, a blunt academic reality that hits her on top of everything else going on with cosplay and club life. Around the same time, the manga club's situation at school reaches a turning point: Mayuri tells Okumura that the principal and student council president approve of his and Lilysa's desire to go public about their activities, but they want the club to keep it secret anyway so Lilysa is not exposed as a possible target for bullying.

After that decision is made, the student council president lays out the practical rule that follows from it: the club may keep using its room, but it cannot keep any risqué material at school. This preserves the club's physical base while forcing them to hide the more suggestive parts of their cosplay work, and it makes clear that their activities will continue only under strict secrecy.

The episode then shifts into recognition of Lilysa's growing presence in the cosplay world. A famous cosplay photographer, Mr. Camera, the same man credited with helping create the Four Heavenly Queens, acknowledges Ririsa as one of the "Five Rising Stars," marking her as one of the newest noteworthy talents in that scene.

By the end of the episode, the central state of affairs is established: the club can remain together in its room, but their cosplay must stay hidden from the school, and Lilysa's reputation outside school is beginning to rise even as her academic struggles and the need for secrecy at school become more severe.

What is the ending?

The ending of Episode 12 is a quiet victory with a hidden cost: the Manga Club keeps its club room, but their cosplay activities must stay secret. At the same time, Lilysa learns a harsh school reality--she is failing every subject in class--while the story closes on the sense that the club has survived, but only by narrowing how openly it can live.

In the final stretch, the episode brings the club's situation to a close by confirming that they do not lose their room. The good news is that the Manga Club can remain together in that space, which means Okumura, Lilysa, and the others still have a base for their activities. The bad news arrives immediately afterward: their cosplay work is no longer something they can do openly, and it has to remain hidden.

Earlier in the episode's ending movement, the story also shifts to Lilysa's personal situation at school. The episode reveals that she is the only student in her class failing every subject, which places a private problem beside the club's public struggle. That detail leaves her ending in a precarious academic state rather than a triumphant one, even as the club itself is preserved.

By the end of the episode, the main characters are left in these positions: Okumura remains with the Manga Club and keeps his role in that shared space; Lilysa remains part of the club, but her cosplay must be kept secret and her school performance is poor; and the club as a whole survives intact, though under stricter limits than before. The episode closes on that balance of relief and restriction rather than on a full resolution.

Is there a post-credit scene?

Yes. Episode 12, "Five Rising Stars," does have a post-credit scene.

In the scene, the story shifts to teasing the next stage of the cosplay arc: Ogino tells Okumura about Mr. Camera's ranking of the "Five Rising Stars," and the episode uses that reveal to set up new attention on Ririsa and the other standout cosplayers rather than resolving everything completely inside the finale itself.

The available episode listings and synopsis confirm that the finale centers on the manga club keeping its room while continuing cosplay in secret, and the post-credits beat functions as a transition into the broader "Five Rising Stars" competition and the next set of rivals and opportunities.

I don't have a source here that gives a frame-by-frame transcript of the post-credit scene, so I can't describe every shot with certainty. If you want, I can still give you a spoiler-heavy, scene-by-scene summary of the full episode based on the available sources.

How does the manga club manage to keep their club room in Episode 12, and what is the catch that comes with that victory?

In Episode 12, the manga club receives good news: they are allowed to keep their club room. The catch is that their cosplay activities must remain a secret, so their win comes with a strict condition that forces them to hide what they are really doing.

Who are the "Five Rising Stars" mentioned in the episode title, and how do they affect Ririsa’s goals?

The episode centers on the idea that Ririsa is competing in the cosplay scene where the "Five Rising Stars" are an important ranking or recognition group. The episode description and related materials indicate that she is trying to break into that top tier, and the situation creates pressure around who is being recognized as one of the standout cosplayers.

What role do Ogino and Magino play in Episode 12, and what information do they reveal?

At Summer Comiket, Ogino and Magino encounter the group and tell them that Mr. Camera has revealed his second- and third-place rising stars, specifically identifying twins among the highlighted cosplayers. Their reveal helps frame the episode's competitive cosplay focus.

How does Okumura react to the club’s situation in this episode, especially compared with Ririsa’s cosplay ambitions?

Okumura remains tied to the manga club's practical concerns, especially the need to protect the club room and keep their activities secret, while Ririsa is focused on cosplay success and recognition. The episode places them in a tension between secrecy and public cosplay competition, with Okumura more concerned with preserving the club's stability.

Why is Episode 12 important for Ririsa’s place in the cosplay world, and what specific achievement is she chasing?

Episode 12 positions Ririsa as a contender in a bigger cosplay hierarchy, where recognition as one of the top rising stars matters. The official series materials connect her and other cosplayers to a larger competition context, suggesting she is chasing status among the most notable newcomers rather than just participating casually.

Is this family friendly?

No -- this episode is not especially family friendly. It carries a MA15+ rating in Apple's listing, and Anime News Network tags the series with ecchi, harem, and "fetishy" cosplay/modeling elements, with significant objectionable content noted overall.

Potentially objectionable or upsetting aspects for children or sensitive viewers may include: - Sexualized fan service / ecchi content - Revealing cosplay outfits and fetish-leaning posing/modeling themes - Romantic tension and harem-style humor - School setting with secret cosplay activities, which may include suggestive framing rather than purely innocent comedy - General mature anime content consistent with a MA15+ rating

I can also give you a spoiler-free "age suitability" recommendation by age group if you want.
