Hello! This is my first fanfic, so I hope you enjoy it and I hope there aren't too many mistakes ^_^; I haven't written anything creative in a while so I may be a bit rusty . Anyway please review if you have time as I really do want to improve my writing skills :)

Ryuji Suguro stood at the front of the classroom with the rest of his peers. Kamiki had just summoned her two demon spirits and now it was Bon's turn. No one was particularly paying attention to anyone else at the moment as everyone was focusing on summoning their own demons. Bon held up his piece of paper with the summoning circle on it and frowned. There was no way this would work, he was training to be an aria and a dragoon after all. He sighed. 'Oh well, no harm in trying' he thought as he pricked his finger with the needle and let the blood drop onto the paper.

"By God's will, grant me the power to defeat Satan" the words flowed smoothly and Bon was surprised at how easily they had come to mind, the phrase was short and memorable. Not that Bon had any trouble with memorising, he had most of the Bible memorised by now anyway, so a few extra lines really didn't matter.

He waited, frowning again as his initial excitement died down. Nothing was happening.

Blue flames suddenly erupted from the ground in front of him and Bon stepped back in shock as the blue flames continued to burn bright. A figure was crouching in the flames. The whole class was watching now, with a mixture of expressions, ranging from fear to shock.

"Everyone, move back!" Mr Neuhaus cautioned as the figure started to rise from the flames.

Everyone stared as the flames began to dwindle and the demon became visible.

"'Sup. you summoned me?" A boy with spiky blue hair, and even brighter blue eyes stood in the flames. He was roughly the same height as Bon, if perhaps a little shorter, wearing black fitted jeans, a plain, dark blue t-shirt and converse shoes. His tail flicked in the air behind him. The boy scratched his nose and slouched slightly, waiting for a reply impatiently.

"Uh...yeah." Not Bon's most eloquent of lines but considering the situation it wasn't too surprising.

"Cool. The name's Rin Okumura. Son of Satan" Rin grinned stretching out his arm for a handshake.

It was at this point that Yukio entered the classroom and joined Neuhaus, raising their guns to point at Rin.

"Move away from him Mr Suguro!" Yukio warned across the classroom, taking the safety off his gun as he did.

Bon moved backwards quickly, but not quick enough as the demon named Rin leapt forward and grabbed the paper with the summoning circle from his hand and turned himself and Bon so that Bon was shielding Rin from any bullets that could come his way. He gripped Bon's wrist in his hand so as he couldn't get away.

"Hey bro, how 'bout dropping the weapons? After all it wouldn't look too good if you shot one of your own students."

Yukio made a noncommittal noise, but after a few seconds he lowered his gun, and Neuhaus soon followed his lead.

"What are you doing here Rin?" Yukio asked, getting straight to the point as usual.

"I was summoned by this student of yours, didn't you know?"

"Tch. Why you specifically? Surely you would want a lower class demon to do your dirty work for you?"

Rin shuffled, letting his grip on Bon's wrist loosen slightly. "You have to judge me so harshly don't you? Don't you remember back when you looked up to me as the best big bro ever?"

"Answer the question, demon!" Yukio had long since destroyed any such feelings to his older brother, his heart knew only resentment now. A look of pain passed through Rin's eyes, far too quick for anyone to see, pushed down and hidden beneath his joking facade.

"Calm down, calm down. Sure, I coulda sent a lower class demon, but I was getting bored, and this dude wants to defeat Satan, I totally want in on that!" Rin laughed, using one of his hands to scratch the back of his neck.

Yukio narrowed his eyes. "Why would you want to defeat your own Father?"

Rin raised an eyebrow, obviously trying to get the point across that Satan was Yukio's father too, causing Yukio to clench his teeth in anger. Satan was not his father. Only Father Shiro could claim that title.

"Let's just say I owe him some pain." Rin muttered. Finally letting go of Bon, knowing his brother was placated enough to not shoot him immediately as he would have before.

He was right. Bon moved away and Yukio came close, keeping his gun lowered, deciding Rin was safe enough for now.

"So what contract have you made with my student?" He demanded, staying just out of arm's reach of the demon boy.

"Same as any other contract, four-eyes. I do what he asks, as long as he doesn't turn out to be a weakling, and in the end I get to kill Satan."

Yukio growled at the four-eyes insult and pushed his glasses up his nose.

"Nothing else? No secret way to bypass the rules? You're not planning to harm my students? Or anyone else for that matter?"

"Not unless punk reject boy asks me to, no." Bon frowned at this and called out.

"Hey! Don't call me that!" Bon stepped closer again, less afraid now that he'd seen this demon was not planning on out right murdering him. "Why'd you answer my summon? Why did you think I was worth the effort from the son of Satan himself?"

Rin turned towards him as he replied "you might not be worth it to be honest, but it's worth a try, and it gives me a chance to stretch my legs at least."

Rin turned back to his brother to ask a question.

"So can I stick around? Be this dude's summoned demon? Or not?"

Yukio pushed his glasses up again. "Come with me, this needs to be addressed by the Grigori."
