Grow Up Show: Sunflower Circus Is the Found-Family Anime Nobody Is Talking About

Every season has a handful of shows that get buried under the sequels and franchise premieres sitting above them on every chart. This season, that show is Grow Up Show: Sunflower Circus, an original anime from A-1 Pictures and Psyde Kick Studio that has been steadily building one of the best ensemble casts of the year while everyone argues about Bleach and Mushoku Tensei.

It deserves better than to be an afterthought.

What the show actually is

Grow Up Show is set in Japan during the late 1950s and early 1960s, at the height of the country's postwar economic boom, back when traveling circuses were still a dominant form of popular entertainment. Rival troupes crisscross the country performing and competing for the chance to appear at the Circus Collection, a prestigious festival that functions as the show's version of a season-ending tournament arc.

The Sunflower Circus, led by ringmaster Maria, is not one of the strong contenders. It is broke, understaffed, and barely holding together when the story opens. Everything changes when the troupe takes in Mizuka Tsurumaki, a circus prodigy whose raw talent gives Maria's ragtag group an actual shot at competing.

It is directed by Kanta Kaimei, with a script from Takeshi Kikuchi, original character designs from Kurehito Misaki adapted for animation by Kazutoshi Makino, and a score from Yugo Kanno. Aniplex produced the series, and Bang Zoom! Studios put together a same-day English dub that premiered on Crunchyroll alongside the Japanese broadcast on July 5.

Why the character writing works

The premise sounds like standard underdog sports-anime shorthand, and in outline it is. What sets Grow Up Show apart is how patiently it lets its cast breathe. Mizuka's arc, in particular, has been the emotional spine of the show so far: a performer who came in with talent but not confidence, slowly learning to trust her own instincts on the trapeze instead of freezing up in front of a crowd. One recent episode built an entire emotional beat around Mizuka finally looking the audience in the eye before her routine, on the advice of a fellow performer, Ouka, to "look at the audience before you fly." It is a small moment, but the show has earned it by spending real time on her fear instead of skipping straight to the triumphant payoff.

Maria gets similar care. She is not written as an infallible mentor figure. A recent episode found her collapsed at the bottom of a staircase with an old locket nearby, clearly overwhelmed by something in her past that the show has not fully explained yet, and it is exactly the kind of crack in an otherwise steady adult character that makes an ensemble feel lived-in rather than assembled from archetypes.

That willingness to give side characters real interiority is what has reviewers describing the Sunflower troupe as a genuine found family, the kind of ensemble a show can spend twenty-plus episodes with and still leave you wanting more when it ends.

Heading into Circus Collection

A video previewing the Circus Collection arc went out on September 5, which signals the show is now moving into its central competitive stretch, the part of the story where all the training and internal drama pays off in an actual performance against rival troupes. For a cast this well-established, that is exactly where a show like this should peak.

Should you catch up now?

Yes, and now is a good time to start. The setup is efficient, the 1950s circus setting is genuinely distinct from anything else airing this season, and the emotional groundwork with Mizuka and Maria means the upcoming arc should land instead of feeling unearned. If you have been skipping it because it does not have a recognizable franchise name attached, that is exactly the reason to give it a shot.
