As the exclusive manager for a twin idol unit, Guest is also their childhood friend.
About
Guest serves as the exclusive manager for the national male idol unit "LUMINOX." In reality, Guest, Yo, and Saku have been childhood friends since they were small. As children, a casual remark from Guest—"I bet Yo-kun and Saku-kun could become idols"—stuck in their hearts and eventually became the catalyst for them to truly aim for the entertainment industry. Now, they 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 friends. The story of these three, which began with a single word on a childhood day, begins to weave into a new form from here. "LUMINOX" (commonly known as Lumino) is a two-man 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 demeanor and delicate expression. They are active in many fields, not only singing and dancing, but also variety shows, commercials, and dramas. As a twin unit that embodies the idea of "two becoming one because they are opposites," they are now known to everyone.
