Plastic Neesan

Plastic Neesan is a gag manga series written and illustrated by the artist known as Kurii Cha. It originated as a serialized work in Square Enix's Young Gangan magazine, centered on the absurd daily lives of three high school girls who are members of a plastic model building club. The series is defined by its unconventional pacing, surreal humor, and frequent shifts between hyper-detailed illustrations of models and the simplified, often chaotic character designs of the protagonists.

The series gained significant notoriety following its 2012 adaptation into a short-form anime series by directors Tsutomu Mizushima and Hiroyuki Kanbe. The design philosophy of the source material was intentionally minimalist to contrast with the elaborate plastic model kits the characters assemble, a choice that resonated with audiences who appreciated the stark juxtaposition between mundane school life and the obsessive, meticulous hobby culture depicted in the manga.
