The moment the people heard what Kuragari just said to the strongest person on earth, they didn't know how to react at all.
On the other hand, Zane was looking at Kuragari's smiling figure with an ice-cold expression.
If it was anyone else, he would have killed them without hesitation, but the situation was a bit more complicated with Kuragari.
He knew him the best. He was like a ticking time bomb, which could explode at any moment. Even a small spark could be enough for him to turn the whole Arena upside down.
Also what made Zane hesitant was two things. One was that when Kuragari disappeared after their fight, no one knew what he did and how much stronger he became. He became stronger than before that's for sure because if not, he wouldn't have just used a priceless treasure as a bet in a wager.
