Kaneki in this form can only avoid Hertza, while Alita, as you described, can negate his kagune. She either detonates it upon first physical contact or neutralizes its power, as you described earlier.
Their heightened senses overlap.
Their instinctive actions overlap.
Their analytical prediction and information analysis overlap.
Their accelerated perception overlaps.
Kaneki's advantage in reaction and attack speed and Alita's skills overlap.
Hertza, which Alita relies on completely in battle, completely overlaps Kaneki's regeneration.
So, we have Kaneki with no advantage in this fight. You mentioned LS, but to use it, you need a hit, which, from what you've written, is impossible without being hit by Hertza. Moreover, you said that she can somehow neutralize his power.
