Osomatsu-san Movie

Following a disheartening reunion with peers who appear to have achieved conventional success, the Matsuno sextuplets retreat to their familiar, somewhat aimless lives. A night of heavy drinking leads them to an unexpected and disorienting experience: a journey through a collective landscape constructed from shared high school memories. This ethereal realm forces them to confront not only their own pasts but also the regrets of those around them, including former classmates and friends.

The sextuplets must unravel the mystery behind this unstable world – and the specific source of its origin – if they hope to escape. As the memory landscape deteriorates around them, they grapple with the potential consequences of failing to resolve a past transgression before being permanently lost within the echoes of adolescence. The series explores themes of regret, identity, and the lingering impact of formative experiences.
