It's OK. You don't have to remove it.
Seems like nobody is replying. All right, I'll post my part.
Editing in progress.
Jonathan slashed and hacked at the horde of skeleton summoned by Johann, but each time he cut down one, two more would rise. This is not good, thought Jonathan. I must defeat Johann first, else they'll only keep coming. But Johann was protected by his impenetrable layer of Bone Walls.
Concentrating his power, Jonathan shifted to his demonic form. He grew large black draconic wings, black horns sprouted out on top of his head, and a long slender black tail sprang out of his back. His hair became longer and wilder, his fangs elongated, and his sclera turned black while his red eyes began to glow. His black cloak twisted and hardened, turning into obsidian battle armor. With a single swipe of his sword which was now glowing red, Jonathan annihilated ten skeletons at once and absorbed their energy before they could regenerate into twenty more.
However, with his heightened senses, Jonathan could see that Johann was also changing. On his back was a pair of great skeletal wings, gray bone-like horns grew on his head, and a bone tail was writhing to strangle the next living creature it touched. Johann's sclera turned dark gray, and his gray cloak transformed into a macabre bone armor. Johann's form was now almost identical to Jonathan's, except he was a warped clone of Jonathan's dark magnificance.
Jonathan cursed silently. Since Johann was a copy of himself, of course he would be able to transform into a more powerful state. To defeat Johann, Jonathan must use a power that Johann did not have... The power of the Master of Darkness. But he could not afford to go to True Form; inescapable fatigue would claim him afterwards. To defeat Johann but not tire himself out, there was only one thing Jonathan could do: to make a bargain with the Master of Darkness inside himself, and ask him to lend some of his power.
Spreading his arms out, Jonathan formed a solid barrier of darkness around himself, protecting him from the swarm of skeletons. Then, closing his eyes, Jonathan gradually retreated into the depths of his own mind.
It was dark, and Jonathan could not see anything despite his enhanced senses. But such was the nature of his mind: Darkness. Jonathan reached out with his hands.
"Bloodshadow, Master of Darkness," Jonathan called. "I have come to make a bargain with you."
At first, there was no reply. Then, two motes of crimson light glowed in the pitch darkness. Upon closer inspection, Jonathan could see that they were eyes, eyes that were like his own but yet not like his own. They were cold, primal, and dark, and within them was the patterns of the Mark of Darkness. They were Eyes of Darkness, the eyes of the Dark Master.
Do you seek my power, Jonathan? Bloodshadow asked. His eyes glowed, and red energy radiated outward from those eyes. Mixing with the darkness in the room, a black and red demonic mask formed around the Eyes of Darkness, giving the Master of Darkness a face. Sanguine flames leaked out of the mask's mouth when it opened.
"Yes, Bloodshadow. I cannot defeat my own clone without your powers, because our powers are equal. As for now I am unable to call upon your powers at will, and thus I ask you to lend me your strength."
We are one and the same, Bloodshadow answered. My power is always yours, but you will need to learn to properly wield such power.
"Yes, I understand that," Jonathan said impatiently. "However, I do not have the time right now to master your powers. I will do it eventually, but not now."
Bloodshadow mused. Very well, he answered. My power is yours, but this time I will not take control of your body to help you wield my power. Use it wisely.
The mask burst into crimson flames. Then, it twisted and enlarged, until it resembled the head of a colossal black dragon. The obscuring darkness around Jonathan evaporated, and Jonathan could see a massive serpentine form before him. When the shades fully disappeared, Jonathan looked up in awe as he beheld the magnificance and glory of his own True Form.
The dragon opened its jaws. Streams of red and black energy, along with streaks of dark lightning, began to gather in its mouth, until it formed a roiling sphere of darkness. Opening its mouth wide, the dragon launched that great sphere of energy at Jonathan, who opened his arms in welcome. The dark energy made contact with his form, melding into and becoming one with him...
In the real world, Jonathan's body began to change again. His black armor became thicker and scalier, and it merged with his own skin; within moments Jonathan's entire body was covered with obsidian dragon scales. His body began to grow larger, gaining more power and musculature; his wings became even wider while his tail thickened and grew a long vicious spike on its end. The horns on Jonathan's head grew longer while his fangs became more prominent, while his eyes turned into the Eyes of Darkness; then his face elongated and grew scales, his red hair turning into a wild mane, until his head resembled the head and muzzle of a black dragon. Right now Jonathan was in the form of a humanoid black dragon, similar to his True Form; but this time, it was his own mind that controlled his body.
Jonathan looked at his blade, which had grown into something entirely different. Its black hilt guard now resembled the head of a vicious black dragon, with glowing red eyes; a blood-red jewel was set into the blade's pommel; and the blade itself became a glowing red claymore, with sinister black sigils carved into its sides. This weapon was no longer the Vampire Gladius; it was now the weapon of the Dark Master, the Soul Eater.
"Soul Carnage," Jonathan raised his blade. A massive blast of pure darkness shot forth from his blade, decimating Johann's entire Bone Wall in one blow.
Finished.
And about that mask... At some point in the future, Bloodshadow is going to forcibly take over Jonathan's body, because Jonathan cannot continue the fight without killing himself. This is probably going to happen in the next fight with Mavros, in which Jonathan wanted to defeat Mavros with his own efforts. When Bloodshadow takes over, that demonic mask is going to appear on Jonathan's face.
Those of you who read/watch the manga/anime Bleach, you'll know that this scene resembles the scene where Ichigo Kurosaki was briefly taken over by his inner Hollow, and the Hollow mask appeared on his face.
