DICLAIMER: I do not own Blue Exorcist or Rin Okumura. I only own my OC (Grace Berlitz). Please don't be harsh. This is my first fanfic. I'll upload each chapter when I can. It'll have only one chapter for now. Maybe two. I'm making Rin 16 in this story. *WARNING: This story contains sexual contact, language, violence, and gore.* You have been warned. Any Questions?

NOW ON TO FRIGGIN' STORY! 

It  was a nice, sunny day. The sun was shinning, the bird sang, but what ruined this nice moment was lovely couple. Not just any couple, it was an odd couple. A blonde girl with long straight hair and green eyes named Grace Berlitz age 16, was dating a 16 year old Rin Okumura. The son of Satan. Half human and half demon. Now this couple have been dating for two years, they were childhood friends before they dated. They known each other since kindergarten. They were on a mission together to look for a demon. 

They found a demon in the middle of the forest, Rin tried talking to it but it didn't listen and attacked Rin. Rin fought it but the Kurikara got cracked badly; it almost broke. He fell to the ground, screaming in agony. His tail was fractured but one of his arm was bent in the wrong way, his wrist had been broken, there was a big gash; trying to heal on his stomach, his bottom lip was cut and there was a tiny cut on his lip. Many other wounds and broken bones were everywhere on his body. 

Rin breathes deeply as his eyes closed before he coughed up blood. The demon was long gone after this and went to move on to another victim in Assiah. Grace screams as she saw a motionless Rin on the ground; not moving at all. Grace's scream brought a lot of people's attention and the group ran to her. Yukio called 911 after they got out of the forest. Since his wounds were way too bad for Yukio to take care, he needed to go to the hospital. 

Soon, the ambulance came and picked up Rin and drove him to the hospital to preform some surgeries on him. A few months had passed and Rin gone out of the hospital. Mephisto came around the corner as Grace was in her dorm, not knowing Rin was out of the hospital. Yukio called her. "Hey Grace, Rin's out of the hospital and he's all healthy again." He said, with a happy tone to his voice. Grace jumps in joy looking around to see Mephisto grinning. 

"So, now that you know Rin's a-okay, you're happy now. Now then, Rin can't use the Kurikara again until it's fixed. If it's broken, his flames will consume his human heart and turn him into a full demon. Don't let that happen." He warned her as he poofs away in some pink puffs. Grace nodded and went off to see Rin. 

After a few days had passed the Kurikara somehow got fixed again and they ran into a different demon this time while on a mission. Rin battled it and defeated it. But the Kurikara got cracked and he went berserk. Meanwhile Grace was going the wrong direction Rin went to and she got lost. She saw Blue flames in the sky and ran towards where they were at. They lead her to a demon Rin. 

Rin was growling and snarling at nothing but he was setting trees and the ground on fire. He noticed Grace and cut the tree behind her down, she moved out of the way before it hit her. Rin growled at her and roars. His tail flickered as the flame at the tip got a little bigger. He ran towards Grace as the Kurikara was next to her. (He threw it at her earlier off screen. :P ) His sharp claws and fangs glistened in the fire. The blue flames soon consume the trees around them as he pounces on her. He pins her down as he drools. He looks at her as one of his hands went for her head to keep it in place.
