Rinku Aimoto, who spent most of her life living abroad in Africa, has returned to Japan to attend Yoba Academy, a school known for its popular DJ units. At Yoba, she meets Maho Akashi, who teaches her the basics of DJing. Inspired by Yoba's famous DJ unit Peaky P-key, Rinku and Maho form their own unit called Happy Around. They recruit Muni Oonaruto, a talented artist and childhood friend of Rinku, as well as Rei Togetsu, a shy and caring pianist. Happy Around aims to use their combined talents and new friendships to become one of Japan's top DJ units.
