Which is where some of the points below come from. Yang was held at gunpoint for injuring Mercury. Not only the guards showed up right after the event but so did the paramedics meaning there are procedures in case of a major injury. There's also the fact that a person doesn't need to lose their entire aura to be eliminated. A reasonable 15% is when the match is decided. What other reason for this than to prevent major injuries?

But why are there not referees to prevent one person from killing their opponent?

Simple. Because that's against the rules. In the real world EVEN if there is a referee these people don't have the strength to stop two real fighters. So why are they not trained for such? Because that's not their job. It isn't supposed to happen. It's clearly illegal!
