It’s not that cinner’s experience is far beyond Kedron, I’m clearly referring to the difference in skill one can cross with Reactive Evolution in Bakuhatsu (Assuming their will is strong enough). Even if Haruka is completely outmatched (Which she shouldn’t be) RE can let her adapt and possibly surpass quickly. Catching Haruka will be extremely hard, especially with Haruka’s own prediction capabilities, again, giving her at least some sort of a helping hand, and there’s also the fact that Cinner can’t predict Haruka’s movements if she decides to switch strategies to counter it, and also the fact that she can move in such a way that she disappears from sight even with equal speed (Already explained in reasoning post, and also from Vol 1 Chapter 7). AND this you are once again assuming Haruka needs to get in close, which she doesn’t need to, given that she can do pretty much the same amount of damage from well outside cinners range.
Stalemated? Asuna outright beat Kedron even when she was starting out at a big disadvantage in skill, speed, power, basically everything, and yet, still won (Though she needed some help from Shizu at the end, but this is still a considerable skill upscale, since Haruka is way more experienced than them both. How come this hasn’t been brought up before?)
