Heya guys, here! I just discovered Blue (Ao no) Exorcist like a bit ago when there were four episodes out in dubbed. I've seen it all, from the dubbed to the subbed and the OVA with Kuro in it. I think it might be my knew favorite anime. Rin is just awesome~!

Now, I came up with this story from a mixture of things. One of them was the song "Save Yourself" by My Darkest Days (Hence the title name, I own nothing!) mainly because the first line is "I'm the devil's song straight out of hell". It's definitely a Blue Exorcist song. I love it. So, I came up with this story thinking about my own OC and wondering why Satan only had sons (You'll find out in the story :D)

So, this is the first chapter, I didn't want to say "her" name yet, but I am sure you can guess what's going on. Please review, I'd love to hear what you guys think all the time~!

!

Songs I listened to (I've been doing this with some of my other stories): "Save Yourself" by My Darkest Days (This one will probably be on every chapter)
"Crush" by David Archuletta (For Yukio)
"My Heart Will Go On" by Celine Dion (Oh this song... yeah, it was one I listened to, you'll find out)
"She Will Be Loved" by Maroon 5
"Can't Forget You" by My Darkest Days
"Trying Not To Love You" by Nickelback

Yukio looked at the address scrolled on the paper once more, making sure he had it right before he walked up to the door. Twenty-one years old and he was still nervous to be around her, think about her, and see her. It's been the same since five years ago. He'd already seen him, now he wanted to see her. It's been way too long without hearing much of her voice even if they did work with each other before.

Time changes things.

He walked up the uneven cement path and to the worn front door. A couple toys were scattered in the small yard. He smiled, thinking of his own childhood with his own twin brother. Their father may have adopted them, and his brother may be the son of Satan, but Father Fujimoto was the one both Yukio and his brother claimed as dad. Unfortunately for him, Yukio wasn't back at the monastery where he and Rin had grown up. He was close to it, but he wasn't there. Instead he was there to see someone else; someone who was close to Rin.

He knocked on the front door, waiting for sounds of someone coming to the door to see who it was. After a few noises and someone, he was sure it was her, talking, the door opened a little.

Yukio stared at the twenty-one year old girl. No, woman. Her beautiful blonde hair was up in a messy bun. Her eyes were still that bright sapphire blue like Rin's. When she saw who it was, a current high-ranked exorcist, her friend, she opened the door more, revealing her filled figure. She'd changed so much and subtly over the past five years that Yukio was blown away. Even with a big hoody on, he could still see her large bust and curves that defined her now. She was quite the looker in school when he was teaching her and Rin; now, she was a stunner. He vaguely wondered if the demons she went after would just give up themselves for her to kill. But, no, demons aren't like that.

"Yukio, what are you doing here?"

Yukio smiled, trying to hide the real reason he'd come. "I was in the neighborhood on a mission, I thought I'd stop by and see you and the boys."

Boys. He'd nearly forgotten she had two of them. They had to be entering school by now; being near about five. Her face or curves certainally didn't show the stress of raising two boys. Then again, you wouldn't have thought the same about Yukio's father.

She smiled, leaning against the door. "You wanted to see us?"

Yukio smiled wider, his eyes closing, trying to make himself irresistible to say no to. "Of course, I want to see you three. Otherwise, I would have seen you at the exorcist meeting."

Even if she was no longer as active as she once was, she was still an exorcist. A damn good weapons specialist at that. She lowered her head, looking sad.

"Oh," she said, somewhat disappointed.

Yukio pressed further, denying himself the permission to touch her like he had throughout the years he knew her. "Can I come in still?"

"As long as you dont mind the mess. The boys...well, the one...can get a little rowdy sometimes," she said, opening the door more to let him in.

He smiled to her, walking in. "It's fine." He scanned the living room and around him. The place was straightened up. For a mom of twin boys, the place was the cleanest place he'd been in with kids. "Nice place you have here."

"Thanks," she said as she disappeared to tend to something. "Make yourself at home."

Yukio looked around the place she'd bought after the twins were born. She refused to stay with Yukio, or live at the monestary where him and Rin grew up. Of course she wouldn't raise her boys there, Rin's presence would be all over the place. Yukio sat down on a couch and looked to the end table beside him, taking in a few pictures. He remembered a couple. One was of her and Rin during the end of one of their successful exorcist missions together, and he'd snapped the picture because both of their smiles shined so brightly. Another was when the twins were born. With that memory, since he was there, Yukio's smile faded a little. He remembered that day all too well. His gaze fell on another one of her and the boys. Clearly it was their first day of school. He smiled at the uncanny resemblence, but cringed internally for the same reason.

How could she look at those boys? Especially the one who looks so much like him?

"Can I get you anything, Yukio?" she asked as she wiped her hands on a towel.

Yukio perked his head up, looking to the blonde bombshell. "Water is fine, thanks."

Just like that, she disappeared again, grabbing a couple bottles of water. When she returned, she handed him one. He promptly took it with a nod as a thanks and opened it, drinking it. He took note that she was still wearing her gold ring on her right middle finger, a silver ring on her right pinkie, and a silver band on her left hand. Yukio shook his head from the thought that it was the one Rin had given her.

"How are the boys?"

"Fine," she said plainly, obvious to Yukio that she wasn't thinking about the answer too much. Of course he knew that answer was going to come from her. She hated it when people worried about her. "Growing up fast."

Yukio couldn't help but to smile. "How have you been, truthfully?"

She sighed, knowing Yukio would press further until he got the truth from her. He often did the same to Rin. "Honestly, overwhelmed. I am not sure how Shiro did it and kept his sanity. I know he was a paladin, and the man was brilliant, but how the hell did he manage to keep his sanity?"

Yukio shook his head. She must be talking about her one twin, the one I suspected would be just like him when he was born.

"I've asked myself the same thing more times than you'll...well...I am sure you know." Yukio looked around again, looking for the one thing he thought was missing. "Where're the boys?"

"Nap. They should be getting up soon."

As if it was rehearsed, Yukio soon heard the quick, heavy steps of five year old boys running down the hall toward her.

"Momma!" one boy cried. He was hearing glasses similar to Yukio's as he threw his hands in front of him, grasping his mother's leg. He was a firm build for a five year old; built like his uncle.

Yukio already knew he was touched by a demon. After all, look at his father.

She smiled, her hand going to the back of her twin son and the other hand running through his hair. "Hello there, Shiro, did you sleep well?"
The small boy nodded happily, causing Yukio to catch the boy's name. Shiro. So she did keep his name Shiro for Rin. He vaguely tried to remember what she named the other boy. After all, he was there when they were born. But that night...was just a roller coaster of emotions for both of them. Yukio just hid them a little better.

"Good, I'm glad, son." She sounded just like a mom would. So caring, compassionate. It was hard to believe how rebellious she was with Rin a mere six years ago. "Where's your brother?"

Shiro shrugged, causing Yukio to chuckle and annouce his presence in the room. "Who is he, Momma?"

His mom smiled looking toward Yukio with that soft smile she gave when she was pregnant with them. "That's your uncle Yukio. He's a great, high-ranked exorcist."

The boy's eyes grew wide with interest and wonder. A great exorcist? His uncle? The boy stepped to his uncle with wonder. Yukio smiled even if all she would know him as a friend and Rin's brother. Damn, that boy. He looked weak now, but he'd grow up to be strong. He just knew it.

"Why, hello," he said, leaning toward what looked like a reflection of him at that age. But the boy had his mom's golden hair instead of brunette like Yukio. Even the hair style was like his. He held out his hand for his nephew to shake. "My name is..."

"Uncle Yukio," the boy finished, catching Yukio off guard. He was smart, too. Throwing his arms around him in his version of a hug. Yukio hugs him back, trying not to engulf the boy too much. "Momma's told us about you."

Yukio looked up to her with question, which she responded with a shrug. Yukio knew why she did it. After all, she was alone while his father had help. Of course stories of her exorcist cram school days and as an exorcist would come up. It was nearly all she knew.
"She did?" Yukio asked, earning a rapid nod from him. Yukio smiled, wanting to hear what she'd put down for their last name. "What's your name?"

"Shiro," he said. Yukio felt the stab of disappointment when he didn't say his last name; he just had to know. He held up his hand, fingers extended as wide as they could go."I'm five!"

Yukio chuckled basking in the hallow glory of being right about the twins' age at least. "Nice to meet you, Shiro." He tried to ignore the nagging memory of the man he knew as Shiro. After all, Rin had personally come up to him and asked to name one of the twins after their deceased father. For her, Yukio would have agreed to anything.

Yukio watched from his peripherals when a second boy came out, rubbing his eyes from sleep. He looked so tiny, tinier than Shiro. "Ma?"

She bent to him, giving him attention. Her fingertips disappearing into the boy's hair like she had with the other twin. There was a small flicker of sadness in her eyes. Yukio could see it from where he was sitting with Shiro. "What is it?"

"I had that dream again. The one where that guy sees me."

The boy opened his eyes all the way, having removed his tiny fist after rubbing the sleep out. His bright sapphire eyes, much like his parents, illuminated against the light. His deep raven hair fell in a messy, layered, rebellious mop. He looked so much like his brother that Yukio had a hard time, at first, deciphering between who was his older, but smaller twin brother and who was his kid.

She brought him close. "I'm sorry, honey." She ran her fingers through his hair and running her fingers down his jawline and under his chin to comfort him, leaving Yukio to wonder. "Did you talk to him this time, or try to kick his butt?"

Without a beat, the young boy said almost excitedly, "Kick his butt. He let me, then wanted me to tell you something."

She sighed a little, like she was used to it. Yukio just wanted to know more. Like who it was. "What was it this time?"

"He wants you." God, that kid had said that so innocently. For all Yukio knew, it was Satan himself and he wanted to use her like he had used Yukio.

"I'm sure he does." She sounded so unamused.

"Momma? Why did he want you?"

Her expression faded into a smile. "Because I am a strong exorcist with an even stronger exorcist on my side," she said seriously letting the tone fade into an almost song-like tone.

This sent both boys into a fit of giggles, leaving Yukio to smile and shake his head. She and I haven't seen each other since about the time the twins were born. Glad to know she still considers me a friend after all that's happened.

The smaller of the twins, the one who'd just woke up with the raven hair. The one who reminded Yukio of Rin, saw him sitting on the couch. He pointed to him with his tiny hand. "Who's this?"

Yukio fought the dangerous tone his nephew tried using. To him, it sounded like a Rin doppelganger from when his brother was five.

She looked over at Yukio with a smile, completely wiping away what her son had said about his dream like usual. "Don't sound so hostile. That's your uncle, Erin."

"Uncle?"

"Yeah, Yukio. You remember telling me about him." Her hand was on the back of his head, rubbing it.

Yukio couldn't help but to beam a little more, glad she mentioned him to her sons. Yukio held out a hand. "Hello, what's your name?"

The boy merely crossed his arms, earning a nudge from his mother. He stepped toward his uncle with a scowl on his face.

"Come on, you can tell him," she urged as sweet as she could.

The boy growled, looking down as he uttered, "Erin Okumura."
