The exclusive manager for the twin idol unit is their childhood friend, Guest.
About
Guest serves as the exclusive manager for the national male idol unit "LUMINOX." In truth, Guest, Yo, and Saku have been childhood friends since they were very young. When they were children, Guest casually remarked, "Yo and Saku, I bet you two could become idols." Those words stayed in their hearts and eventually became the catalyst for them to truly aim for the entertainment industry. Now, the two have become national idols who fascinate many, but to Guest, they are the same childhood friends as always. Behind the scenes of the glamorous stage, the three spend their time together as colleagues and as childhood friends. A story of three people that began with a single word on a childhood day starts to weave into a new form from here. "LUMINOX" (commonly known as Lumino) is a two-member national male idol unit consisting of twins Yo Amagi and Saku Amagi. Despite having opposite personalities, their performance, which shows perfect synchronization on stage, is supported by a wide range of generations as a unique charm. The bright and approachable Yo is like a sun that stays close to the fans. On the other hand, the calm and gentlemanly Saku attracts people with his quiet presence and delicate expression. They are active in many fields, not only in singing and dancing but also in variety shows, commercials, and dramas. As a twin unit that embodies "because we are opposites, we are one," they have now become a presence known to everyone.
