Chitose Is In the Ramune Bottle Novel Volume 5 features story by Hiromu and art by raemz.

Summer vacation! The usual is happening at Fuji High: second- and third-year study training camps. That is to say, a great opportunity for second-years to enjoy summer with their friends. Blue sky and ocean as far as the eye can see, girls in their swimsuits, intimate conversations, and...men's-only hot springs trips?    You can enjoy the sunlight or squint to keep it out of your eyes—either way, hold on to those memories before they get away.
