[Oshi no Ko] Pieyon

One of quirky characters is Pieyon, the bird mask wearing, muscular strength-training YouTuber. He is the top earner of Ichigo Production, the company managing the up and coming B-Komachi. He contributed much to the growth of B-Komachi, firstly by giving Ruby and Kana the exposure for their idol group to his viewer base, while subjecting them to a gruelling physical routine whilst wearing the same bird masks. Later, after Mem-cho joined the group, he was the physical trainer to improve their stamina for their performance, making them sprint up hills and perform numerous rehearsals of their dance routine.

::: spoiler Correction Um actually ... Pieyon did not train the girls. He was on vacation, and it was actually Aqua in disguise that was training them. :::
