I do not Own Blue Exorcist.

Before the attack, Yukio had paired Rin up together with Izumo on a mission, but suddenly as they were in the middle of a battle, there was an attack at the dormitory. At first, Yukio was taking care of the demons well by himself but when things got too out of hand, all the students started to retreat afraid that they would be killed by all the demons that were being sent out from every corner they ran to. So then when one of the students made it far out enough to Rin, he told him about the massive group of demons tearing the whole dormitory apart, and just as anyone would expect, Rin went back to fight alongside Yukio, weary that his twin brother may be killed alone. But there was too much. There were too many all at once. No one knew where or how they were coming out but they knew they couldn't kill them on their own. Everywhere Rin would turn, he was sized up with one after the other, and with Izumo by his side, he couldn't get much done.

Rin fought off as many as he could with his Blue Flames emerging from his body and his sword in hand. He tried looking for Shiemi but she was nowhere to be found, so every dead body he came across he flipped over to check their face. Izumo used all the power that she held to keep herself from being murdered, and she made sure not to run off without Rin. She was prideful but she was no fool. She knew Rin was her only hope of making it out alive.

As the sun came to set, bringing nightfall, the battle was yet to die down. Bloody and nearly torn, Rin still did not give up. He did not give up looking for Shiemi nor did he give up letting the demons overpower him and take over all that he knows. As the fight continued, restlessly through the darkness of the night, the dormitory began to crumble unable to take the damage being given by not only Rin's explosion of Satan power, but also the numerous raging demons lurking around. Izumo grew weak and tired, dragging her legs across the ground to keep up with Rin. He leaped in the air, his sword rising high above the head of an eighteen-foot hog demon. He swung down and sliced the beast in two as if his body was made of Jell-O.

Blood flew out, splashing against Rin's face, and the taste of the demons blood entering his mouth. There was nothing better.

"Rin" Izumo called out as he hit the ground. "We can't do this, there are too many"!

"I don't care" Rin growled.

"Then you'll be killed and I can't let that happen" Izumo said, stomping over to him and grabbing ahold of his arm. "I can't let you fight yourself dead, Rin"

"Don't touch me" Rin ripped his arm out of her grip and glared into her eyes. "Leave, Izumo"

"What"?

"Leave"!

"If you even for a second think im going to leave her without you then you're crazy! I understand you don't want to leave, Yukio, behind but it's our only choice to survive"

"I won't leave until my sword has every last one of their blood stained upon my blade" Izumo could see in Rin's eye that no matter how hard or long she was willing to try, he wasn't going to budge. The furies in his eyes were speaking words for him, and no man on earth was going to be capable of talking him down from saving the dormitory. It was one thing to exorcise a demon from an innocent soul but these demons were out in the open, looking to murder. And the fact that they had Yukio and may have killed Shiemi made Rin's veins pulsate with anger.

"You can't do this alone, Rin. We have to leave" Izumo tried.

"Don't" Rin said. Stepping backwards, moving away from her. "Don't try and stop me Izumo…"

Izumo eyes grew wide as she noticed the demon rising behind Rin. She shook her head violently and screamed for him to move out the way but when Rin turned around it was too late. The beast let out a great roar, echoing through the starry sky, and brought back his hand..

"Rin"! Izumo shouted as she sprinted towards him.
