Honestly, they're still calculating the XX-Burner feat, so I can't say for sure how far into 7-A he is.But they might be using his X-Burner feat for all of their stats as of now. I'd have to ask them.
Yeah, but her shockwaves can be blocked by Hibari's needle spheres. Hibari's chains can also grow to great lengths, of the exact number I'm not sure. But these scans should provide a good estimate of the distance.
The temporarily blinding might work, but Hibari also has his cloud flame radar as a hard counter to such techniques. Hibari has faced illusionists within his verse, so not being able to fully trust his eyes is nothing new to him, and the cloud flame radar was used specifically to counter illusions. He'd still be able to locate and adequately fight Satsuki.
Okay, so it's possible for him to break them, as Adelheid's castle was of a similar durability, though, admittedly, it would be unlikely that he would be able to break them, he'd be more than capable of simply blocking them.
As it stands, for me, it's like this. Satsuki, while having some long range attacks, is primarily a close range fighter. The same can be said of Hibari. However, he has more tools to maintaini a mid distance fight than Satsuki, and could likely wear her down his his needle spheres, handcuffs, and chains before she got too close. Satsuki still needs a way to continously deal not only with Hibari and his three styles, but also with the needle spheres, which will be trying to skewer her from every angle Not to mention that Hibari can control their size with the cloud's propogation attribute, and even mix them into his own fighting style, giving him more variety. I just don't see a few AoE blasts being enough to stop Hibari's constant pressure.
