Still not quite sure about the prior information and what not, so idk
AoE, isn’t all that much, but if combined with a Conductive Interr. as shown in the gifs, it can expand to be quite a bit. I’m sure that Akame wouldn’t have a problem dodging it, the thing I’m trying to point out is that Crashbolt is a very useful defensive tool to ward off Akame’s dangerous sword skills, not talking about it as an attack. Couple this with her teleports, competent sword skill in her own right (fighting someone 114+ years older than you gotta say something about your skill), and her defense is pretty air tight.
Gotcha
And Gotcha, still sticking with my defense argument from above, coupled with range (attacking is a form of defense you can say), so Blade has like, 4 layers of defense, Range, Crashbolt, Sword Skill, and Teleport. You can argue that Akame can fight all of those individually, but Blade can do it all at the same time.
Blade’s lightning is quite possibly the strongest thing in the verse right now, next to like Asimov I guess. A casual shock outright one shotted a guy who stomps the verse’s 3.1 Megaton feat, since that feat was casual, with the whole “Hmph! Is that all you’re capable of” anime thing and everything just to make that point. It’s safe to say that once Akame gets hit by one, she’s gonna be like “oh shit she strong her swings are devastating yo”
