The Osomatsu brothers have always been chaos agents, but this one strips away the noise and lets you watch them just exist together, arguing about takoyaki and pretending a sleepover isn't actually happening. It moves slowly on purpose, the kind of comedy that lives in the spaces between jokes rather than punching you with them. For people who've stuck with these six for years, this is what you came for: proof that watching them do nothing together still means everything.

The sextuplets are getting ready to throw a takoyaki party at their home, but their plans spin out of control once Totoko hints at a sleepover. The film is a comedy with a slice-of-life feel, made to mark the sixth anniversary of the Osomatsu-san anime. It is the second of two new animated projects announced for that occasion, and it had a limited theatrical run in Japan in 2023. The franchise traces back to Fujio Akatsuka's gag manga Osomatsu-kun.
