Rinne Amagi is the leader of the idol unit Crazy:B. Crazy:B is under the management of Cosmic Productions (CosPro for short), and at large, the company Ensemble Square (ES for short). There are three other members of this unit: Niki Shiina (who is Rinne’s best friend), Kohaku Oukawa, and HiMERU. The unit is themed after bees, and all four of them regularly make bee or insect puns to fit said theme. They’re wild and passionate, and often encourage flaws and craziness in the audience. Their songs are usually about being yourself and not worrying about what people say about you, and they encourage radical acceptance.
