Uchiage Hanabi (fireworks ED)

Two voices collide across a shimmer of lo-fi synth and distant piano — a boy and a girl trading lines about a night that feels simultaneously endless and already over. "Uchiage Hanabi" wraps itself in the warm haze of a Japanese summer evening, where fireworks bloom and fade before you can decide whether you wanted to stay or run. The production is deliberately soft-focused, like a photograph left in a drawer too long: drum machines that feel human, synth textures that dissolve at the edges. Daoko's voice is feather-light and slightly detached, as if she's narrating from just outside the moment, while Kenshi's warmer tone pulls her back toward something more urgent. Together they sketch a fantasy — what if we had gone? what if we had chosen differently? — that never quite resolves. The song belongs to the specific ache of adolescence where possibility and loss feel indistinguishable. It became a cultural touchstone because the anime film it accompanied (Fireworks, Should We See It from the Side or the Bottom?) asked the same impossible question as the song itself: can you rewind the moment just before things went wrong? This is music for late-summer train rides, the window fogging slightly, the city dissolving behind you.
