Kataoka Yue has spent two years working her way up at Pythagoras Productions, and now she manages two of its top acts: Marginal#4 and Lagrange Point. A new group called Unicorn Jr. is about to make their debut at Universe Fes, and just as the introductions are done, the company president pulls Yue aside with a larger problem: she has six months to organize Pythagoras All Star Fes, a showcase featuring all three groups. She can only manage one act during prep. She has to choose.
