On the surface, Agastia is a company that specializes in entertainment and is well-known for its theme park. However, under such an outward appearance is a massive secret: Agastia is one of several highly advanced evil organizations aiming for global dominance. Despite its genuine character, the organization offers enticements that make the work atmosphere worthwhile. Agastia, led by its outstanding leader Akashic, has recently emerged as a pioneer in achieving the shared aim of its fellow organizations. Touka Kuroitsu is a researcher with Agastia's Monster Development Division who mostly does fieldwork owing to the peculiarities of her seniors. Kuroitsu's day-to-day tasks also involve making sudden presentations and proposals, satisfying unrealistic demands for monster designs, and escorting those creatures to their doom.
