The music doesn't accompany the visuals, it colonizes them. Tsuda's direction moves at the speed of the track itself, cutting faster than your eye can follow, layering meaning into every frame so densely that you'll rewatch it just to catch what you missed. A single episode that feels like a complete emotional argument, not a promotional object pretending to be art.

Betsu Sekai is a music video for the song of the same name by Amane Kanata, also known as PP天使P, with direction by Tsuda. Its genre labels are psychological and romance. The song exists in two versions: the original sung by Amane Kanata, and a vocaloid version with Hatsune Miku on vocals, which was uploaded later, on February 26, 2023.
