Rent-A-Girlfriend manga volume 6 features story and art by Reiji Miyajima.

At Chizuru’s request, Kazuya agrees to go on a “practice date” with Sumi-chan, who’s trying to make it as a rental girlfriend despite her crippling shyness. It’s an opportunity for Sumi-chan to practice being social, building confidence and earning power—or it’s supposed to be, until who should butt in but Mami-chan! And she has a bombshell to drop… A practice date quickly turns into an all-too-real battle!
