Shirube is a single music video for the song of the same name by Tokoyami Towa, directed by Nene Futamura. The track also plays as the opening theme of the anime Yuusha Party wo Oidasareta Kiyou Binbou, but here it gets its own standalone animated video. Viewers who know the song from that series, or who follow Towa's music, can watch it as a one-episode companion piece.
