A single song about finding happiness in the smallest thing, a bag, and it means everything because the animation trusts the music to do the work. There's no plot to chase, no tension to resolve. Just a child discovering that comfort isn't complicated, rendered in the kind of soft watercolor palette that makes you remember why you loved animation in the first place. It's five minutes that feel like they were made for the exact moment you need them.

Shiawase no Kaban is a single-episode music video made for the song of the same name by Becky♪♯. The video appeared on Minna no Uta, a program aired by NHK, and it stands as a standalone music release rather than a story-driven series.
