Low Rise!!!

Riku left his job of 3 years to enjoy an extended break. One day, his aunt called to ask him to become a producer at her new idol production studio. He did not show much interest at the idea, but she suggested that he come watch a mini concert by one of her idols on the rooftop stage of a department store. There he saw his cousin Rin, who he had loved like his own imouto, giving it her all in a spirited yet amateurish performance. Afterwards, he was named as her producer. With the addition of his clumsy imouto Nono and her energetic classmate Kogiri, the SLG (semi-little girl) idol unit “Low-rise!!” was formed!
