To promote the forthcoming release of the Nintendo Switch version of the BanG Dream! Girls Band Party! rhythm game, the BanG Dream! franchise’s official YouTube channel has started streaming three original web CMs featuring 42-year-old Japanese comedian/bodybuilder Nakayama Kinnikun.
The Nintendo Switch version of BanG Dream! Girls Band Party! is set to be released in Japan on September 16, 2021.
As his name implies (kinniku means muscle in Japanese), he was selling his own muscles for his comedic career.
