Throughout Japan, there are both evil secret organizations that seek to conquer the world, and superheroes who rise up to challenge them. One such evil organization, Agastia, operates out of a base hidden underneath a front company headquartered somewhere in Tokyo. Agastia's attempts to conquer the world are often thwarted by the superhero Divine Swordsman Blader. This story focuses on Miss Kuroitsu, an assistant in Agastia's Monster Development Department, responsible for creating a monster powerful enough to defeat Blader once and for all. However, this organization operates like any large corporation, as Kuroitsu and her Department are forced to fight for resources and funding with other Departments in the organization, make proposals to the board to justify their costs, or deal with their leader's whims forcing them to redo their designs at the last minute.
