To do so, he leaves his work at his father's publishing firm and joins Marukawa Publishing. Instead of being sent to their literary section, Ritsu is assigned as the rookie manga editor for the Emerald editing department, a staff that works under incredibly tight constraints. There, Ritsu meets the famed editor-in-chief Masamune Takano, a hardworking man who demands results.
