Having spent most of her life in Africa, Rinku Aimoto returned to Japan to pursue her education at Yoba Academy - a prestigious institution renowned for its exceptional DJ units composed of skilled singers, dancers and DJs. It was there that she met Maho Akashi, an aspiring DJ who introduced her to the art of DJing. The captivating performance by the academy's legendary DJ unit, Peaky P-key, was a source of inspiration for Rinku and Maho, spurring them on to create their own group. Muni Oonaruto, a childhood friend with exceptional artistic talent, and Rei Togetsu, a kind and introverted pianist, were quickly recruited by Rinku and Maho. Together, they formed Happy Around - an unstoppable unit that had their sights set on becoming one of the top DJ units in Japan. The group utilized each other's strengths, cultivating newfound friendships along the way.
