A single episode that trusts silence more than explanation. Namiko Ishidate and Ryokuoushoku Shakai built something that doesn't announce itself, doesn't demand your attention, just sits with you until you realize you're crying. The kind of short that proves you don't need runtime to change how someone feels. This is for people who hear a song and suddenly see a whole world inside it. The music isn't decoration here. It's the story.

Himitsu no Hana no Niwa is a single-episode ONA music film from 2023, directed by Namiko Ishidate with music by Ryokuoushoku Shakai. It was made as one of five collaboration shorts for the TOHO animation Music Films project, which brought together artists and anime creators to mark the tenth anniversary of TOHO Animation. Its genre labels are drama, music and the supernatural.
