Well, let me just start by mentioning (again) that Heriman is not a human being. Sure, he was once, but he isn't anymore. Herriman doesn't need to recognize Mifune's attack. If there's a chain around your sword, and I throw that chain to the side, I know it's going to balls up your attack regardless of whatever you're trying to do.
Swinging your arm to the side is not an action that takes a lot of time, and there are many animals out in the world (insects, mostly) that can build up tension in their legs like it's nobody's business. Likewise, The sound of muscles rearranging is in no way an indicator of how long it takes someone to mutate. If it took Herriman five nanoseconds or five years, it'd still sound like cracking and squelching. It's not impossible. Let's not forget that the arm was already mutated (because, you know, it was a flail with an extendable chain, the muscle structures are already in place for that sort of thing.
Similarly, raising my sword arm isn't exactly a costly action either. I can swing my other arm and launch the chain while raising my sword-arm.
Unless of course, if what you're trying to tell me is that Mifune can kill Herriman from fifteen feet away before he could even have a chance to raise his arm to the side (just to put things into perspective, I'm a pretty out of shape guy, but I can swing my arm in front of my torso in a full arc in less than half a second, raise my arm from straight down at my side to pointing directly away from towards my side in less than .20 seconds).

. Realistically by the time Herriman got his arm to the side he would be stabbed .
Huh, looks like that
IS what you're trying to tell me. I'm sorry, but I think it's my turn to call OP. If Mifune can pull his sword out of the ground, wrestle with the chain, and still maintain enough goddamn balance to perform a jumping stab attack before Herriman can swing his arm (a time of at most a FIFTH of a second), from fifteen feet away (from a crouching position with his sword embedded in the ground, might I repeat), that's absolutely ludicrous.
