Ok, here some quotes regarding what i said previously.
Ikki's speed was so great that no one in the stadium could see him move, not even Muroto (who is a former A-League Blazer). Even stating that Ikki's movement surpassed even the A-League. Even thinking that Ikki was using Ittou Shura.
> "Indeed, Ikki movements could not be seen, even by the people in the commentator's booth watching the match from afar. He had simply disappeared all of a sudden, and before anyone realized it, had passed Moroboshi by and cut him down."
>ÒÇîMuroto-pro. Do you know something about this? Is this, in fact, the Worst One's rumored Ittou Shura?ÒÇì
>ÒÇîN-No, this isn't Ittou Shura. There was no change in the amount of magic power Kurogane was using. That… was pure swordplay! And while there are differences between two-sword and one-sword styles, I have seen that sort of untrackable instant acceleration of body and blade once before….ÒÇì"
>ÒÇîWhere on earth could that be? Don't tell me, it was in the A-League!?ÒÇì"
> ÒÇîYou can't find it in that place, because… this swordplay belongs to someone whom every country has given up on capturing due to her outrageous strength. This is the swordsmanship of the world's greatest swordsman, and its most wanted criminal in history—Twin Wings Edelweiss!ÒÇì"
Yuudai who previously was easily able to fight Ikki was completely blitzed once he used Edelweiss Swordstyle.
> "What… is this? I was cut!? But I couldn't see anythin'…."
> "Having said this, he vanished from Moroboshi's sight. He disappeared…!. He did not in fact disappear, of course, but having skipped the acceleration process and achieved maximum output upon stepping forward Ikki got off to a rocketing start that Moroboshi's motion perception simply couldn't follow."
> ÒÇîAah! He's been hit again! Moroboshi is letting Kurogane get into range too easily! He's completely unable to follow his movements! Once again, Sanrensei has struck the empty air!ÒÇì
>ÒÇîIt can't be helped…! Kurogane's extreme highs and lows in acceleration and overwhelming speed is something that even we cannot catch from long range, what more when it happens in front of one's eyes! It's more than likely that the Seven Stars Sword King can no longer see the form of the Worst One!ÒÇì"
> "Something impossible was happening before Moroboshi's eyes. He could hear them. The sounds of any number of slashes, and of footsteps moving at a dreadful pace. His opponent was unmistakably close to him, and yet—What is this, what is going on!?—no matter where he turned to look, there was no one there."
During the fight with Bloody Davinci he fought against a Fake Edelweiss who was as strong as the one who fought with him previously.
> "ÔöÇÔöÇThat was because of the performance of the fake was lower after all. Wrong. Ikki could tell as he clashed swords with her. At least, fake Edelweiss could not be weaker than the time he fought against her at Akatsuki Academy in the past."
Ikki can now fight with her without Ittou Shura, something imposible to him previously
> The sword flash of pure white and darkness intersected. They collided, and sparks immediately scattered as the gales of steel clashed. That's right. Ikki clashed with her. He had to rely on Ittou Shura in the past, but he could finally keep up with Twin-Wings's swords!
After learning Edelweiss Swordplay he obtained a huge increase in his basic battle strenght, so now he can fight with Ittou Shura level opponents while in base.
> Even so, to be able to match up without Ittou Shura... (That's just how much stronger I have become!). He had obtained Edelweiss's sword technique from Blade Steal. And the brain signals for battle that he switched in order to execute it. He obtained a large amount of experience from that one fight. Thanks to that, Ikki's basic battle strength had increased tremendously compared to that time. Even without relying on Ittou Shura, he could already keep up with the battle in that territory!"
After he defeated Fake Edelweiss his opponent created four copies of himself, each of them using Ittou Shura.
> "Purple Caricature, Another One!!!!". With a drawing speed that could be even faster than Ikki or Edelweiss's swords, she created a fake Ikki. What's more ÔöÇÔöÇ four of them.
Ikki the defeats the four of them (he had the advantage of completely knowing their strenghs and weaknesses though)
> Ikki immediately recollected his confused mind from seeing the fakes, and decapitated one of the four fakes that challenged him with Ittou Shura, rendering it to paper scraps. On his second breath, he easily cut down another one. However, that's also obvious. Since his opponents were none other than Ikki himself. What he was good at. What he was poor at. What would be coming from that posture. His advantages and disadvantages. His habits and tendencies ÔöÇÔöÇ he knew them all better than anyone. Those half-heartedly made fakes would not be a match even if there were four of them at the same time, no matter how close to perfection they were."
About the clones strenght, in the previous round she used one against Kuraudo (who had trained a lot in order to defeat Ikki) and Kuraudo barely defeated it. The clones strenght are not bellow Ikki's, just that they do not think as much as the original (so no tricky tactics).
