A single song carries the weight of memory, and the animation trusts you to feel it without explanation. The visuals move like the music moves, patient, circular, returning to the same moments from different angles until you understand what they meant. This is what happens when a music video stops performing and starts remembering.

Sonna Omoide ga is a single-episode music video built around the song of the same name, performed by Duke Aces. The song was featured on Minna no Uta, a program broadcast by NHK.
