On a remote island, Producer comes across a shrine that looks like Haruka-san and suggests a trip to look into the artifacts kept there. Once they arrive, the group divides into smaller teams, each heading off to explore a different site on the island. What they uncover on this outing drives these short comedy specials. Adapted from Akane's four-panel spin-off manga, the episodes were released as bonus extras packaged with the Blu-ray and DVD volumes of Puchimas! Petit iDOLM@STER and with the limited edition of the manga's fifth volume. Expect light, musical slice-of-life humor.
