Nobody talks about this one. A single perfect artifact: Suisei's voice moving through space that feels both infinite and intimate, animation that doesn't fight the song but dissolves into it. The planetarium isn't a place you're watching, it's the inside of something alive, turning slowly while she sings directly at you across the dark. Five minutes that cost nothing to experience and everything to forget. This is what happens when a musician and a director understand that the song doesn't need proving, just witnessing.

Planetarium is a single-episode animated music video made for the song of the same name by Hoshimachi Suisei. saino directed the piece, which sets animation to the track. As a music release, it is a short visual companion to the song rather than a full story told over several episodes.
