A single perfect moment frozen in animation: two people at a summer pool as the evening light turns everything gold, and that's the entire story. Ai Niina animates what Tatsurou Yamashita actually lived, not what a screenwriter invented, so it carries the weight of real memory translated into color and movement. The song rebuilds a feeling you've already had without knowing it, that specific ache of a day ending too soon, of being young with someone who mattered. It's 3 minutes that understand summer better than any 12-episode show ever will.

Ai Niina animates this music video for Tatsurou Yamashita's song Sayonara Natsu no Hi, made to mark thirty years since ARTISAN, his tenth studio album. The track is a freshly remastered version drawn from Yamashita's own high school memory of visiting an amusement park pool with his girlfriend as the sun went down. Told entirely in Niina's animation, the video centers on time and the fragile, risky nature of youth, pairing summer longing and teenage sentiment with a modest hope about growing up.
