The hour long Asylum Session film is set in a distant future in which society has stagnated. The runaway teen girl Hiyoko, to be voiced by Aya Hirano (Haruhi Suzumiya, Konata in Lucky Star), takes up residence in a tent city nicknamed "Asylum" and becomes involved with the other young residents that launch a street culture festival called "The Asylum Sessions" to counter the plans of profiteer-minded police.
