Yosaku  

, 与作

Yosaku is a guy who often pops up wherever theres 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 Kinnikumans 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 Bibinbas 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).
