Rent-A-Girlfriend manga volume 12 features story and art by Reiji Miyajima.

Kazuya’s second date with the school-uniform-clad Sumi at the aquarium continues. Sure, things got off to a bit of a hectic start, but now that they’re at the live aquatic show, they can finally relax and enjoy things…right? Poor Kazuya’s been absolutely distraught trying to think up a way to help Mizuhara, and maybe a chaotic distraction is just what he needs. A little fresh air can really clear the head, or was it fresh water?
