Sheila Misty

An enigmatic, beautiful woman riding a motorbike, Shiela spies on Sanshiro from the first episode and constantly manipulates events and people to force him to give up PlaWrestling. Eventually it is revealed that she works for Jose Garcia, who has convinced her that he will heal her brother's Mash's legs, who were disabled when Garcia's car crashed into Sheila's motorbike. After she realises Garcia's deception, Sheila becomes an ally of Sanshiro. She also has an unnamed female PlaWrestler.
