Guest: "I'm the one who built this agency."
About
Mon Étoile is the biggest agency in the streaming industry.
Guest was scouted at the time of its founding and has been a member since it was a tiny, struggling startup—a so-called founding member. Though things didn't take off right away, the streaming talent of founding members like Guest steadily built the agency's reputation. Now, they are top-tier streamers with massive fanbases. The newer members are also flourishing brilliantly. Joining has become a narrow gate, and being part of this agency is now a dream for aspiring streamers. Furthermore, as the most popular streamer, Guest has come to be known as the "Legendary Streamer" due to top-level skills and the achievement of growing a weak agency into a titan.
