Once again, Rin was carelessly losing control over his flames, blasting them in any and all directions to attack whatever hurt his friends. The ever taunting Amaimon had summoned one of his strongest demons to attack Rin and his friends – to provoke him into exposing his powers once again – out of mere boredom. The exorcists in training had been sent out on a simple mission and were supposed to be back in class three quarters of an hour ago. Mephisto was growing more and more amused with each burst of power that flared from his half-brother.

"Without the ability to tame Satan's power, he's still as useless an opponent as he was during our first encounter." Amaimon spoke to Mephisto. His voice barely showing any hint of emotion.

Growling ferociously, like the hybrid demon he was, the blue flames grew some more around him, his teeth growing longer and sharper, his face scrunched up more in hatred. This time, Rin didn't even appear to have any human emotion left in him. His blade easily sliced through everything it came into contact with. Suguro, Shima, and Kamiki were all badly injured on the ground. Rin felt he had no choice but to eliminate this creature before it could harm anyone else.

Mephisto told Amaimon to end this at once. For Mephisto to call something off, a demon who based his life on gambling with chance and fate, that meant something serious. And as much as Amaimon didn't want to, he listened to his brother and called his demon off, but only after he, himself, had gotten close enough to Rin to land a forceful blow to Rin's face with his fist. Having the last hit meant he would have won, in his mind anyway. The blue glow lit up a huge area of the forest where Rin had landed. Amaimon sighed and his creature disappeared with a snap of his fingers. His dull expression now aimed at his brother's more than amused one.

"What happened?"

"Things just got a lot more interesting."

Cocking an eyebrow, Amaimon asked, "How do you mean?"

"Can you not feel that another demon is here, coming to attack the source of all that power? Not to mention that faint glow of pink over there falling from the sky above him that will surely make this night one to remember."

Now interested, Amaimon looked back towards where Rin had fallen, and then above him to where a tiny light that was growing bigger the closer it got, was falling. Biting his dagger-sharp nails, Amaimon waited atop a branch of a tall tree in anticipation to see what would happen next.

"If they're falling for Okumura's sake, just think of how much fun this will all be!" Standing proudly, his arms in the air and his expression darkening, Mephisto packed up his chair and all of his tea and desserts into his hat before teleporting back down to the earth. Strolling towards the ruckus while spinning his umbrella, the demon principal couldn't keep the smile off his face.

"It's here!" Mephisto called out, smiling. He had made sure the other exorcists were safe at bay before allowing this fight to continue. Yukio, Konekomaru and Shiemi had all shown up just in time to help treat their friend's wounds while the Mephisto was distracted.

Rin was back up in the air, jumping from tree to tree, looking for Amaimon. He was mid-jump when he was hit with a gale of wind that was stronger than any demon he'd ever fought before – Satan excluded, but then again he hadn't actually fought him, but merely survived an encounter.

Another heavy gale of wind knocked him about. Rin had collided into a few large trees, bringing them all down with him. Blood was pouring out of the teenager like there was no tomorrow. He had only just managed to stand back up when he was hit full-force by another gust of wind. It had sent him back a fair distance, slamming into more tree trunks as he flew back out of control. He was caught before he hit the largest tree that wouldn't have even budged on impact. Rin was already unconscious and was laid down gently by the other, a glowing ring placed around his neck. Before they had left him, a whispered hymn was spoken and then, they were gone from the scene. The demon that had found something to possess in Assiah followed the newcomer like nothing else mattered. Originally set on Rin, it couldn't pass up the chance to have a spar with that pink flame.

"Rin!" Yukio called out, running to his aid. His gasp silencing everything but his heartbeat thudding in his ears when he saw what had been placed on his brother. Checking his twin's pulse, he was relieved to find it beating strong. "Why must you always be so reckless?"

Back at True Cross Academy's infirmary, Yukio was keeping a close watch on Rin's vitals until he woke. Mephisto had suggested it and that was one of the few times Yukio would do as his half-brother said. Yukio was still concerned about the ring around his brother's neck. He could not remove it, no matter what he tried. Mephisto had also mentioned there was no point in trying as the only one who could remove it was the one who put it there. Yukio had asked Mephisto if he knew anything about it, the demon principal had told him to just wait until Rin woke and not to stress.

Unfortunately, that was easier said than done, and Yukio wouldn't listen to him about that.

"Rin..." Yukio held his brother's hand tightly and rested his head on his twin's. "I hope you're okay and whatever this thing is, isn't doing you any harm."

I've never written for any other fandom (other than Kuroshitsuji) before. Just thought I'd see how I'd go XD Any feedback is welcome.
