The middle-aged man, who was assigned to facilitate this match, did not mind being shouted at as he stood at the center of the stage.
"Stand behind the line…" He said to the two as they needed about 15 meters of distance from each other.
After he confirmed that the two were already in position, he continued…
"There is no time limit in this match. If you left the stage, it's considered a surrender and I'll end the match. If you were put unconscious or I think that you're about to die, I'll stop the match and it will be your defeat… You're allowed to use any weapons of your choice but any external assistance once the match started will result in disqualification and be considered a loss. Do you get it?" The man asked the two on the stage.
"Yes!"
With this reply, he immediately announced the start of the match!
