The nightmare that wiped out two thirds of the human race thirty years ago wasn't caused by germs. It was bugs on an entirely different kind of scale: bizarre insects that mutate their victims into half-human creatures that rapidly evolve into rampaging giant monsters!
Yet, as unstoppable as the monstrous insects seemed, humanity is as hard to kill as cockroaches, and exterminators like Kidou now spend their lives stalking and killing the creatures called Cagasters. As the brief still-partially human phase is the best time to strike, however, exterminators soon learn to distance themselves, socially and emotionally, from normal people. But when Kidou finds himself suddenly tasked with returning a young survivor to her mother, he starts to realize that his emotions and humanity may not be buried as deeply as he believed!

Where it came from
Cagaster of an Insect Cage originated as a dōjinshi manga series by Kachō Hashimoto, which she self-published online starting in 2005. Set in a post-apocalyptic world where a mysterious disease turns humans into giant insects, the narrative explores the survival struggles of a young girl and a specialized exterminator. Its transition from an indie web-manga to a commercial anime adaptation reflected a growing industry interest in unique, gritty survival stories that originated in the independent digital space.
The 2020 anime adaptation was produced by Studio KAI and directed by Koichi Chigira. Designed to translate Hashimoto's distinct, rough-hewn aesthetic into a 3D-heavy animation style, the production aimed to emphasize the industrial grit of the series' wasteland setting. Upon its release on Netflix, it was received as a niche but ambitious project that attempted to balance action-oriented insect combat with the character-driven melodrama characteristic of the original source material.
