A single character sitting alone in the dark while the chorus builds. That image holds the entire weight of the song. The animation barely moves, but the fireworks behind her fracture in time with every beat, turning stillness into something that breaks open. It works because supercell's chorus doesn't need movement to hit, and the visuals trust that completely. This is what an ending theme sounds like when it actually means something to the story it closes.

Utakata Hanabi is an original animated music video for supercell, whose song was used as the 14th ending theme of Naruto Shippuden. The lyrics center on a woman, now an adult, recalling a summer day from her past when she went to a festival with the boy she loved. As fireworks lit the sky, she snuck a look at his delighted face. While they rested by the side of the road, laughing and watching, she confessed her love and they kissed. She never met him again after that day, and she looks back on that brief moment with regret.
