Teriyaki Yoko

Teriyaki Yoko is a diva. They debuted in Um Jammer Lammy and are the Teacher of Stage 6: Taste Of Teriyaki. Yoko comes off as ill-tempered when first met to emphasize their diva/idol status, having roses appear behind them when shown in full view. Yoko is negotiable and expresses gratitude and praise if you pass. When it is clear Lammy is not Rammy - the one supposedly accompanying their gig - they simply roll with letting Lammy do the gig as the show must go on. Due to the mystery of where you are, Yoko comes off as unpredictable with their powers. They are only shown to control electricity in-game. Alternate media such as the guidebook imply that they are able to seduce or control other people via mind control. Their entire stage being an entirely new dimension (Hell) also plays into 4th wall breaking with the credit roll and failing their stage results in them saying that Lammy should be banned from every game. In other words, Yoko, their manager, and Lammy are aware of the 4th wall's existence. According to the Japanese Um Jammer Lammy Guidebook, Yoko hates to be referred to as feminine (or at least the concept of idols needing to be feminine) and goes by multiple nicknames. Specifically, they are referred to as both 'Yoko-chan' and 'Yoko-sama.' When discussing them, other characters will use gender-neutral pronouns.
