The sextuplets' ability to derail any narrative is the joke, and a quest for a wish-granting fruit is the perfect setup for that chaos to unfold across a whole movie. Their comedic timing as a unit, built across six seasons, means every brother's failure compounds the last one in ways a standalone would never land. What saves this from being just another gag-structure adventure is that these six have already earned the right to waste your time being stupid together.
The sextuplets set out on a big adventure to find a fabled fruit, one said to make the deepest wish of whoever eats it come true. The movie is an adventure comedy spun from the Osomatsu-kun gag manga by Akatsuka Fujio, turning a treasure hunt into a vehicle for the brothers' brand of silliness. It is the first of two theatrical projects announced to mark the sixth anniversary of the Osomatsu-san anime, with a second film planned for the following year.
