Nobody talks about this one. A single animated frame stretched into something that feels like a complete argument about what happiness even means, set to a song that refuses to give you easy answers. Ootori built a visual language in one episode that most shows can't sustain across twelve.

Yuu Miyashita's Koufukuron, which the anime Platinum End took as its first ending theme, is the song behind this music video. Ootori animated it.
