Yeah....Kirito is completely screwed here

For starters, Arbiter has already seen all the outcomes that stem from this battle, as all Sirens have the ability to see through the infinity of outcomes (as shown with Observer gazing through them when talking with Bismarck) and this is really bad because Arbiter would then use her control over causality and possibility to counteract these outcomes (Since Kirito isn't acausal, he gets royally bodied)

Additionally, Kirito can't even incapitate Arbiter, much less kill her due to being reliant on humanity's perception (and due to her being an abstract)

Overall, Kirito loses badly here
