早乙女姉妹は漫画のためなら!?

Mobuyuki Saotome is sixteen and already serializing a romantic comedy as a rookie mangaka, with his two sisters working as his assistants. Eighteen-year-old Noan and fourteen-year-old Kanon throw themselves at the job, posing as models and going to embarrassing, hands-on lengths to gather reference so their brother's series is not canceled, and both grow more attached to him as they do it. Deadlines keep arriving, and the two sisters complicate every page he draws.
