Kokoro who was once an Olympic candidate of Judo, starts working in the major publisher - Koto Kan. Assigned to the editorial department of Vives - a weekly comic magazine, she starts learning the basics of editing. Along with the deputy chief editor, Iokibe, she goes to a meeting with the most popular cartoonist of Vives - Mikurayama. Although she is excited by the real comic production at first, later Mikurayama rises turmoil by telling that he will take all of his submitted work back from the publisher. Through her work as an editor, Kokoro begins to feel as fulfilled as when she used to play Judo. Their mutual goal is to make a comic that can get reprinted, in other words, make a sleeper hit. With the help of her colleagues and cartoonists, Kokoro strives to make a "sleeper hit". -- TBS
