Heihachi Mishima vs Hayate and Ayane
The Mishima Financial Empire has been on the radar of the Mugen Tenshin clan for some time. Mainly because its owner, Heihachi Mishima has bought out DOATEC.
When the M.F.E. is found to be sponsoring a tournament (not the Iron Fist Tournament), Hayate and Ayane decide to compete. Hayate goes undercover as Ein while Ayane goes as herself.
But the ever-scheming Heihachi knows who they are. Not having a good match in a while, Heihachi takes them both on in an endurance match.
