@Sane, for Rufus he was taken out in two hits, not one.

As for the Mira vs Seilah fight, it wasn't technically OHKO because they both received hits and blows prior to her Etherious Mode, and she may have not paid attention to the Elfman attack though she was already felt fatigued from the take over attempt from Mira, she even freaked out and was so fixated on her and not her surroundings and tried to end it, even if she was in her top form anyone can feel tired or fatigue that are vulnerable to unexpected hard hit attacks.

@Nick, then Kagura only has the speed for her swordplay and perception of battle.
