The manga centers on the Kuroitsu, an assistant researcher in the superhuman development department of Agastya, a villainous secret organization that battles with heroes who try to save the world. Kuroitsu lives a busy life in Agastya, caught between the absurd requests of her bosses; making presentations; implementing new features into superhumans; and getting results within the allotted time, budget, and spec requests; all without vacation.
