[@Savato]
Considering the fact that Satsuki is able to rip apart entire buildings with the shockwave caused by a single swing of her sword..... her strength is so much beyond sam's that they're not even in the same league. And again, it's impossible for him to even harm her without using two swords and using them like scissors, a weakness so arbitrary there's no way he'll figure it out. While he might be able to outmatch her in speed, there's no indication he's superior in skill. Combat experience I might grant you.

First hit Satsuki lands, she's going to go straight through the Vibrosword, and straight through everything behind it. The only question is whether he'll be able to have his blade uselessly strike her before she annihilates him.
