Music video
'Kingyo Hanabi' is a simple video that shows Otsuka singing underwater and on a small island during dawn/dusk. While Otsuka is on the island, she holds a firework in her hand that emits golden sparks, which then rain down around Otsuka who is under the water. Otsuka sits on a veranda looking at a man and reaches out tentatively, but he moves away before she can hold his hand. She then slowly falls to the ground and cries before disappearing.
