After getting his shoulder bitten off, Ren already lost consciousness. Usually, the other incarnations wouldn't care if the current incarnation dies in battle, but it's a different matter altogether if it's against the ORIGIN. Even if it's just one of its seeds, they can never lose to the ORIGIN.
So after Ren lost consciousness Edge Regius took over Ren's body. Among all the incarnations who have too overpowered techniques hat Ren's current body can't handle, Edge's style was created so that even the weak could use the sword to become powerful.
...
After cutting one of Fean's arms, Edge started to assess the current condition of Ren's body. The right shoulder was still working but the rotation was not to his liking. The left leg was experiencing severe muscle trauma that could slow down his movement. A few ribs have been broken and the lungs were being squeezed by some of the broken ribs.
The blood flowing from Ren's head was flowing towards his right eye making his vision blurry. His jaw was slightly dislocated, and his eardrums were booming. Overall assessment Ren's body could only handle a few more minutes of battle.
...
While Edge was assessing Ren's condition Fean took the arm that was cut off and reattached it to his body. He just placed it back to where it used to be and it reattached itself, Lance was surprised to see this, Silika, on the other hand, already knew that would happen.
Back in the final battle against the agent of the ORIGIN that also had a seed of the ORIGIN. Silika saw the agent regenerate any body part that was cut off, even beheading him didn't work. For as long as he had mana he could regrow any body part.
Though it seems like this one had a weaker version of that skill. Seeing as he needed to get the dismembered body part and reattach it. The one Silika and the others fought back then could grow the body part back.
Aside from that Silika also noticed the change in Ren's demeanor. It was only a slight change but Silika was able to notice it since she has always been watching him. The one facing Fean right now was no longer Ren. Instead, it must be one of Ren's many incarnations.
...
Edge saw Fean reattaching his right arm and sighed. He wanted to finish this quickly but seeing Fean do what he did made Edge think that this fight was going to end a bit too close for comfort.
Right now with Edge's skills, he could've won against the current Fean with little effort that's if Ren's body was still in tip-top shape. But now that Ren was hurt all over this battle became a bit more difficult. Still, this just made Edge feel even more excited.
After Fean reattached his arm he once again charged at Edge with a speed greater than before. It would seem the longer the battle lasted the more in sync Fean becomes with seed, which greatly increases his abilities.
Fean who was now in front of Edge was going to attack but then he saw Edge was no longer in the same spot. Edge had already passed by him. It was at that moment Edge's voice echoed in everyone's ear. It was not loud but for some reason, everyone heard what Edge said.
"[Moon Edge Style- Moonlit Dance]" After Edge passed by Fean with but a single stride, Fean's whole body began to separate. Edge was able to cut Fean's whole body into a hundred pieces.
Once again no one was able to see Ren draw his sword. Yet he was able to cut Fean multiple times. Lance thought that this should finish the berserk Fean, but before the pieces of Fean's body severed from each other, they bonded together again.
Edge had already guessed that might happen so he was waiting ready for it. Edge once again used Moonlit Dance and cut the already sliced pieces of Fean's body into even tinier pieces.
Yet even though Edge cut everything into even tinier pieces, Fean's body still seems to be trying to reattach itself. When Edge saw what was happening to Fean, he decided to see what happens when he finishes reattaching himself.
After a few seconds of waiting Fean's whole body was fully repaired. But Fean was now breathing rather heavily. It would seem that by trying to reattach his severed body parts, Fean had consumed a lot of stamina and mana.
Edge now knew that there was a limit to his regeneration. He then smiled the same vicious smile as Ren and all the other incarnations.
"Since this is the first battle I had in ages, I'll allow you to witness the pinnacle of the Moon Edge Style."
Edge's Spirit Aura covered Ren's body in a smaller layer than normal. The ground Edge was standing on started to crack and looked like a spider web. He then slashed at Fean, which confused Lance and Silika. Fean was at least ten meters away from Edge, and the sword he was using wasn't that long.
They thought Edge made a mistake, but then they saw Fean trying to block from his left side. This move of Fean was also confusing since Edge was obviously aiming for the right side.
After hitting Fean Edge changed the position of his sword. He placed it near his chest and held the hilt in a reverse grip. Same as the first move Lance and Silika weren't able to see Edge unsheathe the sword but they were sure that Edge attacked using it.
Fean who tried to block the attack had his blocking posture break instead, he was now off-balanced. Edge then started charging forward and as he got nearer to Fean his body multiplied and there were now seven Edge's surrounding Fean.
At first, Lance who was watching thought that the clones were after images or fakes, but then when Edge started attacking from all sides Lance knew those clones had a physical form.
Fean's animal-like stance was broken by that move. As Fean stumbled about, Edge released a massive amount of mana and channeled it into his sword. Once the mana gathered was sufficient enough Edge swung the sword down at Fean disintegrating Fean's body.
That was the Moon Edge Style's final form. It was a series of moves that made defending practically impossible.
Moon Edge style (final form) first stance [Earth], was used to confuse the opponent's senses.
Moon Edge style (final form) second stance [Heaven], was used to break the opponent's guard.
Moon Edge style (final form) third stance [Unity], was used to break the opponent's stance.
Moon Edge style (final form) last stance [Eternal Moon], this move was another variation of [Silver Sword], a move used by the hero Shun another one of Ren's past incarnations and Edge's past life. [Silver Sword] was a move that gathered every ounce of mana you had into your weapon and unleashed a final strike. [Eternal Moon] was a weaker version of that. Instead of pouring all your mana for a final move, this move was made to control the output, so that you won't faint after one usage.
