Kuromu’s true identity happened to be Crocell Keroli from the Misfit Class! The more Keroli talked to Iruma, the more she became jealous about how popular he is, and she ends up collapsing. There was no way that Keroli could continue with the concert, but she had a reason she could not cancel the concert. In order to somehow still make the concert at Makubari Dome a success, Iruma and his friends do something rather surprising!
