Not only is this my very first crossover but it's also my very first FMA and D. Gray Man fic. I'm feeling very accomplished because of it. :D So anyway this take place almost directly after Edward joins the military and a few months after Allen turned Mana into an Akuma. They are both twelve. So yeah sorry for any OCCness blah blah R and R blah blah you know the rest. Enjoy~

Oh and one more thing. The chapters will be switching between Edward's and Allen's point of view. So next chapter will be Allen then Edward again and so on and so forth. You get it.

Edward Elric heaved a sigh as he gazed out the window wishing he could be anywhere expect for the place he was in now. Dammit Roy... I joined the military for one reason and that was to get Al and I our bodies back. I don't see why I have to sit through introduction. The twelve year old thought bitterly. Sighing again he tried to focus his attention on the man in the front of the room. It was hard though because Edward could feel the stares of the other rookies watching him trying to figure out why a kid so young was in the room. That and... what this man was saying was boring. The man was going on about something along the lines on what a noble choice these men had made by joining the military blah blah follow orders blah blah be heroes blah blah. All Edward could say about this introduction was that it was more like a motivational pep talk to get rookies to feel good about whatever it is they would be ordered to do than anything else. He felt his gaze shifting back to the window wishing he could be out there like Al was right now. He wished he could see Al from here but unfortunately this was a back window and all Edward could see was the alley between this building and the next. Al would be waiting in the front. Maybe. It was getting a bit late so Al might have already headed back to their room or perhaps went to find someone to talk to. Something else had just grabbed his attention though. A person had just stumbled into the alley and collapsed in exhaustion next to the garbage. Concerned Ed stood from his chair and hurriedly made his way to the door.

"Mister Elric is there a problem?" The man giving the introduction asked obvious annoyance written on his face and constrained in his voice.

"Um yes actually there is a problem. And I really have to go." Edward said hoping the man would be satisfied with that answer and just let him go without incident. For once things actually went as planned and the man let him go. It helped that he had never wanted to have Edward sit through his speech to begin with. He hated kids.

Edward didn't waste any time getting to the where he had seen the person fall not even stopping to get Al. He only stopped when he was next to the person. White hair... he must be an old homeless man. Please don't be dead! Edward thought as he turned to person over on his back.

"What the..." Ed said shocked. This was a kid! The kid groaned in his sleep before peaking his eyes open slightly. When the kid saw Ed leaning over him he reared up surprised and startled slamming his back against the wall.

"Wow! Hey calm down!" Ed said concerned.

"Who are you?" The kid demanded suspiciously.

"I'm Edward. Who are you and why are you sleeping on the streets?" Ed asked. Thankfully the kid relaxed a little at the straight answer.

"That's a little direct, and not to mention personal, isn't it? My name is Allen." The boy said slightly defensive but at the same time friendly enough to let Ed know that he wasn't truly offended. Just guarded. Edward could understand that considering that's how he was too. That didn't stop him from playing along however.

"Your the one sleeping on the streets not me. I could offer you some food and a place to stay but, it's your choice if you would rather stay out here..."

"Wait!"

Ed grinned smugly. That had done it the kid wouldn't refuse now.

"Well... I suppose I could tell you a little about myself, if that's what you want to know..." Allen mumbled uncertainly but the temptation of food proving to be to much for him.

"Alright then. But we'll talk over a hot meal ok? I can't say that the food here is the best I've ever tasted but you look like you could eat just about anything am I right?" Edward said happily. It felt good to be able to help someone, even if they had just met. Allen offered him a shy grin.

"I suppose that's true." he said. Edward offered out his hand and helped pull Allen up.

"Wow... one of the things you have to explain is that eye of yours." Edward said just noticing the scar. Allen flinched slightly at the remark before countering with one of his own.

"As long as you explain your hand. I could be wrong but it feels like it's made out of metal."

Now it was Edwards turn to flinch lightly mumbling a excuse.

"It's a long story..."

"So is mine." Allen said evenly. Edward gazed into the gray eyes and suddenly he wanted to hit himself. How could he have forget the law of equivalent exchange? Alchemist practically live by that law.

"Alright I'll exchange your story for mine." Edward said.

"Deal."
