ZKK was destined not to happen because Zoro is weak. An individual who prefers the life of his idiot captain over his dreams and his own life. An individual that his dream is actually a promise, ie, not exactly what he wants but yes an obligation. An individual who, when defeated by the WSM, in addition to promising the man or himself that he would never lose again, promises his boss as a subordinate. This is Zoro, a subordinate who neither the right to be vice captain nor right hand has officially won. This is Zoro's place, in the gutter with Sanji.
It is not my wish for this subordinate Roronoa Zoro, whore of Joyboy, to defeat Mihawk.
Understand, this manga is from the MC and only him.
