"Tease! Rip him apart!" Tyki snarled as the butler lunged at him. The skull butterflies formed and shot forward but did little against him as Sebastian smashed the creatures easily. Tyki's eyes widened as he was kicked again, sending him skidding back. His golden eyes narrowed and he summoned another tease. This time the creature expanded and changed into a glowing weapon that almost looked like a beam of purple light. When the demon came for another strike, he deflected it this time with the new tool then slashed at him. Sebastian leapt back, still getting grazed by the attack and he smirked.

"Looks like you are finally going to fight," he mocked, only pissing off the Noah more. He attacked once again and it soon became apparent that even though Sebastian was fending off the strikes, he was no longer landing many attacks without his own weapon. Focusing on Tyki's movements, he waited for him to attack again. When the chance came, he side stepped, surprising the Noah enough to give him enough time to slam a foot into his side. The attack gave Sebastian little time, but he looked around them. The exorcists looked stunned and torn at what to do. Kanda was helping Grell with Road, but the others watched nervously. Sebastian dashed over to the reaper as Tyki stood.

"So sorry, but I need to borrow this for a moment," he said as he snatched the chainsaw right out of Grell's hands.

"Bassy wait! You can't just-!" The red head shouted, cut off as a razor sharp candle zipped past his head.

"Lavi, help them! Lenalee get the young master away from here. I will take care of this," Sebastian snapped at them. They looked reluctant, but both moved to help. Sebastian landed in front of Tyki, who looked at the new weapon in confusion.

"That's an odd tool…" He said, then looked stunned as the machine roared to life and Sebastian lunged with such speed that he ripped deep into Tyki's chest before the Noah even moved. He gasped in pain, feeling the blood begin to spread down his shirt and his vision began to blur a little. The shadow of a man in front of him moved again and he quickly held up his sword to block it. The force of the chainsaw hitting it was bone-rattling and the glowing stopped as it hacked through the transformed tease and nearly cut off Tyki's arm if he hadn't jumped back in time.
From the sidelines, Lenalee had taken Ciel a few roof tops away so it would be safer. They still watched, but she was prepared to grab him and jump away if the fight moved again.

"Why did you listen to him?" the boy asked, surprising Lenalee. He wasn't looking at her, eyes locked on the fight, and his tone sounded odd, as if he was irritated at her for helping.

"Well it is my duty to protect people, and you are just human…" She said, sounding a little unsure. She really couldn't decide if Ciel was an enemy… he was in league with a demon, but this demon didn't really seem all that… bad. He had helped them a lot and was even fighting the Noah to protect them right now. She looked over to Allen, trying to figure out what he thought, but realized Allen hadn't moved back with them. The white haired exorcist was still on the rooftop.

Sebastian moved in for the kill, ready to slick of Tyki's head when suddenly the saw clashed into another sword. To his surprise and Tyki's, it was the black and white sword of Allen's innocence.

"STOP IT!" Allen shouted over the roar and grinding sounds of the saw. It died and Sebastian stepped back, a little confused. "You're ripping up his soul! There's still someone in there! Before he was a Noah!" the exorcist snapped at him, placing himself between the Noah and the demon.

"Well, that is what happens when someone who is not a reaper wields a scythe… it can cause some problems with that," Sebastian said with a shrug.

"Besides, why do you care? I've been destroying akuma souls since I joined the Black Order," he added and the boy's eyes flashed.

"You destroyed them?!" He snarled

"Well, I do not fight with innocence and am not a reaper. A demon cannot send a soul to the next life. Demons can only consume souls but as I am in a contract, I could do nothing but destroy the pitiful souls," he replied calmly. Allen's temper flared and his silvery eyes changed, becoming a deep golden.

"You traitor! How could you do this?! You lied to us all and killed those people! You are worse than an akuma!" He snarled, remembering how Road had made akuma self-destruct and how painful it was for a soul to be destroyed without innocence. The man in front of him was the opposite of everything he believed it and it was making the exorcist lose control.

"I only followed the orders of my master," Sebastian said, then jerked back as the boy suddenly keeled over with a loud scream.

"ALLEN!" Lenalee shouted as she heard him in pain. Her boots activated instantly and she shout forward, but someone stopped her. Kanda had blocked her path.

"What are you doing! MOVE!" She said, desperate to help Allen but Kanda grabbed her arm and held her back.

"Lenalee say back," Kanda warned, his tone dead serious and almost hinting at fearful. The idea that Kanda was afraid of something was enough to make Lenalee freeze in place and watch from where he held her.

Allen slowly rises again and his friends watch as ashen gray spreads over his skin. A row of black stigmatas break open on his forehead, causing a trickle of blood to run down his face.

"You… must be stopped… demonnn," Allen says but his voice comes out in a different tone, a lower sound that causes Lenalee's blood to run cold. He looks up to the butler with a dead look in his now completely golden eyes.

"You must die."

Note: I really hope you like it! Another user suggested that Neah gets awoken and I loved the idea =3 I hope it all made sense though! If you didn't quite get it, Allen kind of snapped because he has his side for akuma and humans and Sebastian kinda mess up both so he got really pissed. Feedback please!
