I read the chapter and think that she didn’t try to kill him. She makes only one attack and the VA was servile because he doesn’t attempt to fight her and wait till her time is up. If Hancock intends to fight Momonga seriously he won’t have a change to win this fight in my opinion.
Well first let's say this turning into stone does in fact KILL you as opposed to just freezing you indefinitely.
I don't understand how you would think Boa did not try to attack the VA. Momonga stabbed his own hand to prevent himself from being affected by her DF power while all of the soldiers kept lusting for her, therefore turning into stone.
The VA doesn't attack her because he is under order to bring her in to help fight, what good would attacking her do? It will just drive her to even more not want to fight in the war.
He must not return empty handed so he even decided to wait 2 days in the calm belt for her.
You say the VA will lose against her, what evidence do you have of this speculation?
