The next day, the tournament was scheduled to continue as planned.
There was no delay or announcement regarding Ulv Sylvester being dead or having people inspected.
Seeing as Ulv was a traitor, his death was of little concern to The Authority. It was not important for them to waste precious resources trying to find his killer. For them, the priority should be to keep the news hidden as well as to keep everything normal.
Zero's parents recovered and were discharged from the hospital. As their son no longer participates, they headed back home and decided to continue watching the tournament on their TV.
Zero did not stop them and thought that it was best for them to stay in the house. He also called NightShade and asked them to send a couple of Rank-As to protect his parents.
Even when he knows that Ulv Sylvester is dead, he can't rule out the possibility that others people might try the same antics.
