Grey handed his white scarf to Rai, "Take care of this, I don't want to get it dirty."
Walking down the arena Grey spoke up "I accept the duel.", making the whole arena burst into cheers.
The opinion of the people was along this line:
"What an insane kid, I thought he wouldn't accept the duel."
"Now I kind of want to see this kid win."
"I can't help but root for this guy to win."
"There is no way a no name will be able to beat the son of the Dirksen family."
"Dirksen is a family of warriors, they are trained right from their childhood. There is no way that guy named Grey is winning."
The whole arena was divided into two, people who were supporting Grey and people who were supporting Killian.
It's in the nature of human's they can't help but support the underdog, everyone wants to see the underdog win.
