Pieyon

Pieyon is a male “masked muscle-training YouTuber” who wears a chick-shaped mask and swimsuits while performing fitness routines on his channel.

Despite his extremely suspicious appearance, he has become the top earner and main money maker of Ichigo Production.

He first appears in the “Dating Reality Show Arc” as a collaborator who helps launch the new idol group B Komachi.

He later reappears in the “First Stage Arc,” indirectly coaching the group’s training through remote guidance.

When wearing his chick mask, he speaks in an exaggerated duck-like voice that has become one of his trademarks.

His videos are especially popular among younger audiences, making him a celebrity in the world of kid-friendly fitness content.

Pieyon is highly professional and does not tolerate sloppiness when it comes to work.

He pushes others hard in training and takes his role as a creator and coach seriously.

At the same time, he openly admits that he is weak against authority.

This contrast between strict professionalism and deference to power makes him quirky and humorous.

His on-camera persona is loud, energetic, and slightly chaotic, filled with over-the-top introductions and catchphrases.

Underneath the bizarre costume, however, he is an experienced performer with a strong sense of responsibility.

Pieyon is affiliated with Ichigo Production and currently stands as its most profitable talent.

His channel is extremely successful, to the point that his annual income is around 100 million yen.

Before becoming a YouTuber, he worked as a professional dancer and choreographer.

This background explains his precise movement, rhythm, and ability to design effective training routines for idols.

He uses his performance experience to blend entertainment with fitness, making exercise fun and engaging for younger viewers.

This combination of showmanship and technical skill is a key reason for his popularity.

Collaboration with B Komachi

In his first appearance during the “Dating Reality Show Arc,” Pieyon is asked by Ichigo Production president Miyako Saitou to support the debut of Ruby Hoshino and Kana Arima.

He becomes the first collaboration partner for the new B Komachi and helps boost their visibility.

Pieyon initially proposes a “wake-up prank” video for the collaboration.

However, Ruby requests a plan that involves as little lying as possible because it is their first job as idols.

Respecting this, Pieyon agrees to a new企画: a “masked one-hour endurance muscle-training exercise challenge, no face reveal if completed.”

The idea is that Ruby and Kana must endure a full hour of intense training in masks; if they succeed, their faces will not be exposed in the video.

Pieyon is prepared to be lenient in editing and cut them some slack if needed.

Instead, Ruby and Kana complete the challenge without needing any favorable editing, impressing Pieyon with their dedication.

Moved by their effort, he sends them sincere encouragement, acknowledging them as true professionals in the making.

This moment helps establish mutual respect between Pieyon and the members of B Komachi.

Training the New B Komachi

In the “First Stage Arc,” Pieyon is announced as the training supervisor for the new B Komachi.

His role is to guide their physical conditioning and performance stamina.

However, during this time Pieyon himself is actually on vacation in Hawaii.

Instead of appearing in person, Aqua Hoshino disguises himself as a fake Pieyon and takes his place in front of the girls.

Aqua uses the Pieyon persona on-site, while the real Pieyon watches footage sent by Aqua from his vacation.

From there, Pieyon provides remote instructions and advice based on the videos, effectively coaching from afar.

Even with limited screen time, his involvement significantly shapes B Komachi’s training regime.

His combination of professional insight and eccentric presence leaves a strong impression on both the characters and the audience.

Pieyon’s content is especially beloved by children in elementary and middle school.

His bizarre chick mask, swimsuit look, and hyperactive voice create a comedic, memorable character that kids instantly recognize.

Despite looking like a suspicious half-naked man in a mascot head, his influence and views make him a dominant figure in Ichigo Production’s business.

Even Kana Arima, who initially dismissed him as a mere gag character, is forced to respect him upon hearing about his huge earnings.

Within the world of Oshi no Ko, he stands out as a symbol of modern creator culture: unconventional, visually striking, and extremely profitable.

He demonstrates how online personalities can rival or exceed traditional entertainers in both popularity and income.

In a special epilogue manga included in the final volume, a ranking of best-selling celebrity photo books is shown.

Second place in this ranking is a photo book featuring Pieyon on the cover, titled “Pieyon’s P!!!,” where he appears in swim trunks and shirtless.

Right next to it, the first-place spot is taken by a photo book of Minami Kotobuki, which has an average star rating of 5.

Pieyon’s photo book, by contrast, has an average rating of 3 stars, suggesting that while it sells well, its content strongly depends on individual taste.

These details emphasize that Pieyon is a polarizing but unforgettable figure.

Even in a world full of idols and actors, a half-naked man in a chick mask can still become a top-ranking photo book seller.

In the anime adaptation of Oshi no Ko, Pieyon is voiced by Taishi Murata.

His voice performance emphasizes Pieyon’s exaggerated duck-like tone and manic energy.

In the live-action adaptation, Pieyon is portrayed by comedian Crystal Noda from the duo Magical Lovely.

This casting underlines Pieyon’s blend of comedy, absurdity, and showmanship.
