About Pieyon
Pieyon is a masked fitness influencer famous for brutal workout videos and his chicken-like mask, which he never removes on camera. Hired to train the new B-Komachi, he pushes Ruby, Kana and MEM-cho through punishing dance boot camps. Behind the comedy, Pieyon is a shrewd professional who understands exactly how stars are built, and what their bodies and minds can take.
Appearance
Pieyon is a powerfully built fitness instructor who is never seen without his mask, a cartoonish chicken-like headpiece that covers his entire face. Under it he is, by all evidence, extremely muscular; over it, he is a brand. His workout clothes are bright, tight and camera-ready, and his whole presentation is engineered for thumbnails: huge gestures, huge voice, huge energy. Nobody in the story has ever seen his face, and Pieyon treats that mystery as sacred.
Personality
Pieyon is loud, theatrical and relentless as a trainer, and quietly one of the most professional people in the series. He never breaks character on camera, never shows his face and never confuses his persona with a personality, which makes him an oddly honest teacher for three girls learning to live inside idol images of their own. His boot camps are comedy; his standards are not.
Background & Story
