This is a chibi spinoff that exists purely to let you hang out with the idols when they're at their smallest, silliest, least concerned with stardom. The comedy lands in the spaces between cuteness and absurdity, where a tiny idol can derail an entire scene with one deadpan reaction. If you've ever wanted to watch these characters when nobody's watching and they stop performing, this is it.

The idols of 765Pro already lead hectic daily lives, and things get even busier when a group of tiny, very cute creatures called Puchidolls appears at the studio. Each Puchidoll resembles one of the idols in appearance and personality, and many have odd quirks, such as one who multiplies on contact with water and another who fires beams from her forehead. This episode 0 OVA adapts the Petit iDOLM@STER four-panel spin-off manga and introduces each idol alongside her matching Puchidoll. It is a lighthearted comedy with a slice-of-life feel and a musical backdrop, and it was bundled with an issue of Dengeki Maou magazine.
