It change nothing in what i have tell? Musashi can fight with someone like Mibu
Kengou Battou: Ishana-Daitenshou: Following her fight with Saber Emperio, she fully mastered her technique. She is now no longer limited to choosing existing possibilities. She can now create new ones entirely, and find an answer that lies outside the bounds of possibility.
Musashi have her heavenly eyes who can see and choose through infinite possibilities. When she battle Yagyu she couldn't find in any of the infinite possibilities a possibility to battle him.
Suigetsu revolves around the concept of calm water that reflects and mirrors anything. As such, a swordsman that has reached Suigetsu is able to read and react to any opponent like water that reflects and mirrors anything. Using this technique, he is capable of accounting for all possible outcomes, and staying a step ahead of all of them. It is so absolute that Musashi had to create a completely new possibility to manage to bypass this technique.
And for atk being the "absolute truth" musashi have the same way. Her blade just shave down all infinite possibility to the only she created. It's a technique that allow her tu cut low 1-C thing
Her blade has become one that shaves down all of existence to a single possibility. This is the true form of
Zero, a technique designed to create an inescapable end, even against the gods or
The Buddha.
