Kyuukyoku Choujin R

The Camera Club of Harukaze High School prepares to go on its annual photography trip. This trip was scheduled by Tosaka, an alumnus of the Camera Club. Through a travel agency, he was able to plan a "Stamp Rally" tour. This agency, however, is owned by Saionji Marii's family, and she despises the Camera Club.
