Yosaku

Classification: Human
Homeland: Japan
First Appearance: Manga Chapter 5, Anime Episode 1

Yosaku is a guy who often pops up wherever there's a TV camera, doing an impromptu naked fan dance.

In the anime he is known for appearing just about anywhere and performing numerous jobs, most notably working at Kinnikuman's favorite gyuudon place. He also will often fill in as announcer with Nakano-san.

He appears frequently throughout the series as several different character, including Bibinba's father Horumon Yaaki, and had a longer tenure than the more recognizable Nakano-san.

His nickname is "Be Anywhere Do Anything Yosaku-san" (何処にでも出てきて何にでもなる与作さん Doko ni demo Detekite Nani ni demo naru Yosaku-san).
