Nobody talks about this one. A single animated short built around a Billain track that treats the music not as background but as the entire reason you're watching. Hideki Inaba animates it with the precision of someone who understands that electronic music doesn't need narrative permission to devastate you. The visuals don't illustrate the song. They move inside it. This is what happens when a director respects sound enough to let it lead. Five minutes that prove you don't need a story to change how someone feels.

Infinite Blue is a single-episode sci-fi music video made for Billain's song of the same name, which also goes by the Japanese title Mugen no Ao. Hideki Inaba handled the animation, pairing his visuals with the track in a short piece built around the music.
