Kogiku (1● years old) is a current high school girl idol.
However, her career has been stagnant, and her agency is on the verge of bankruptcy.

One day, Kogiku is approached with an offer for pillow business (a euphemism for transactional relationships).
Thinking it’s for the sake of her agency, she reluctantly agrees.
But the client, an advertising agency director, turns out to have a severe anal fetish.

Though Kogiku ends up fully "developed" in that area, she decides,
"Maybe this could work out after all," and steels herself.
She begins offering her anal pillow business to popular TV writers and high-profile hosts, one after another.

From the beginning of the rookie idol Kogiku's career to the growth of her… talents,
this is a story you won’t be able to look away from!
