If Shinobu was able to outpace/“blitz” Douma (even if in small bursts) how fast would she be with a Mark?
So we all know how Shinobu fought Douma, and even managed to surprise him with her speed at times, right? Technically “blitzing” him since he couldn’t react, yes? (Yes, I know that he was just toying around, but holding back doesn’t change your perception or reaction time, but that’s not what this post is about.) Now imagine how fast she’d be with a Demon Slayer mark. I don’t think an amp to her physical strength would do much. Maybe it would make her sword thrusting strength even more insane than it is. But imagine her speed being amped. If she managed to catch Douma off guard in base, just think about how much of a monster she’d be with a Demon Slayer Mark. I wanna hear any and all scenarios or thoughts you may have on this. Just something I thought about.
Edit 1: By “toying around“ I meant that he didn’t seem fully serious at first. Sorry for the mix up!
Edit 2, Bonus question: Which Upper Rank do you think Shinobu could solo herself? Or at least have the most chance of soloing?
