I don't own anything but the plot and stuff…

Hope you guys like it….

Chapter one

A yawn escaped the young man's lips as he rubbed his left eye with a gloved hand. Three nights with no sleep had passed since he had found something in his project. He knew he was getting close, but sleep was beginning to overtake him and slow down his progress.

Slowly, he picked up a rack of test tubes and carefully moved them to another work table to begin his new chart for the data inscribed within the tubes. One by one, he carefully took a bit of the contents with in the tubes and placed a small portion on slides and under a different microscope for each.

He bit his bottom lip as he moved from one to the other and wrote the information he saw. After writing down the last bit, he sighed and sat down on a near by chair. All that was left to do was wait and hope that the new cells would react the way he wanted them to. Unfortunately, it was up to the tests themselves to come up with the answer he was searching for.

About half an hour had passed when the scientist got back up. With a slow intake of air, he picked up a new chart and began to look into the microscopes and record the data for each, one by one.

"First test, results. Negative. Cells have rejected the vitamins." He put an x on the small box for results and moved on. "Second test, results…" He paused for a bit and moved the lens to get a better picture. The cells on the slide looked alive still, but appeared to be struggling. Some were a fading pink while others retained their bold red color. "Results, possibility , but need to be redone. Some cells have remained while others appear to be trying to maintain life. Experimental drug needs to be retested, possible positive outcome." As he moved onto the other two, they came out negative as well.

"Tests show the new drugs all failed but test drug two. Percent possibility of success, 38 percent. A second experiment will be performed on the drug. Unknown outcome for now."

With a yawn, the young man stretched. Three nights with no sleep could make any one tired. He carefully relabeled the tubes and put them into a freezer and cleared the work area. He looked at his watch and sighed. It was 2a.m. With a final yawn, the young man walked out of the lab and turned off the light. He slowly made his way up the stairs and was greeted by a very annoyed face.

"Three days." The other figure slowly walked up to the young man and repeated the same line. "You stayed in there for three days Zero! Why did you lock me out!? I could have helped, or at least given you food to keep you moving! But you stayed locked in that damned lab of yours for three whole days running that same experiment and living of off energy bars!"

Zero put his head down. "I'm sorry, but it was such a huge discovery that I had to test it as soon as possible Ichiru! Do you have any idea what could happen if I find a way to heal, or at least slow down leukemia on both children and adults!?" Ichiru kept his arms folded over his chest as he scowled at Zero. He let out a long sigh as he looked at his older brother's tired, yet happy face. "Just, next time, let me help, al right Zero? I was worried about you when you didn't come out. Besides, the hospital called and said they needed you there as soon as possible when your vacation ends."

Zero smiled at his brother and nodded. "I'm going to bed, I haven't slept in a while, and Ichiru?" The younger twin looked at the older. "Thanks for worrying about me. I wont leave you out anymore ok?"

The younger twin nodded and walked beside Zero. "You look like a zombie Zero. Let me help you to bed before you die from lack of sleep." With one swift lift, Ichiru had picked Zero up like baby and carried him to his room "Why you little-" and dropped him on his bed as gracefully as a sack of potatoes. "Sleep tight bro. I'll see you in a few hours."

Zero sighed and leaned back. As soon as the covers were over him and his head was on his pillow, his eyes were closed and he was in dream land.

Ichiru smiled as he watched his brother's even breathing. Zero was too young, like himself, to be working so hard and pushing himself. For crying out loud, Zero graduated at 15 and began college a month later. He received his degree at 23 and began working only weeks later. Ichiru was amazed at his brother. They were the same age, but in different leagues.

But, there was one thing that Ichiru was always better at than Zero. He knew the world. Even though Zero was smarter than anyone Ichiru had ever known, he was naïve and innocent. Zero was still pure and didn't find any one interesting in that way. He always shied away behind Ichiru when he didn't understand something about life. Just like a child, Zero found something that peeked his interest. That being science. Sure he loved being a surgeon, but he also found experimentation fascinating.

As hours passed, Ichiru had also gone to bed and awakened much later. It was one of his off days. He was an assistant forensics anthropologist. He had about a month until he received a full degree and was already getting offers at certain areas of the country to become the head of the team. He stretched and began to make food for himself since he knew Zero wouldn't get up for a couple more hours considering he hadn't slept in so long.

With a glance at the clock on the wall, Ichiru looked out the window. It was about 10 in the morning and the weather was slightly chili since the temperature had begun to go down to tell everyone that autumn was slowly turning into winter. The trees outside danced to their own music as their long limbs reached up towards the heavens. Ichiru noticed that almost all the leaves were gone and only a few stragglers remained.

A few birds could still be heard as they scavenged the ground for some food before parting for the cold winter months. With a slow yawn, Ichiru grabbed his coat and walked outside. A small jog should do him good and wake him up.

As he began down the streets, he noticed that there weren't that many people around. It was strange, usually there were many outside on days like that one. He guessed it must have been the cold weather that had kept them inside on a Sunday morning. A small yawn escaped his lips as he looked around. He reached into his pocket and pulled out his ipod and began to run once more.

About half an hour later, Ichiru slowly walked up the steps of his and Zero's home. It wasn't big, but it wasn't so small either. They could afford their own place if they wanted to, but preferred to live together. Besides, they were each other's halves in a way considering the fact that they were twins.

After entering the house and putting the light jacket up, Ichiru made his way to the living room as he blew hot air onto his cooled hands. He flopped down into the living room couch and grabbed the blanket that he had left the day before beside the couch.

He snuggled into the warmth the blanket offered and turned on the TV. After flipping through a few channels, he left it on HBO where a movie he liked was going on. As he watched with interest, he didn't hear the rustle of sheets across the hall. His eyes focused solely on the scene unfolding on the screen. As the climax neared, Ichiru was tackled. With a startled yell, he came to the realization that he was being pinned down by none other than his own flesh and blood.

"Had a good nap?" He tried to sit up as Zero sat on his stomach, but with no avail. "Yeah, it was good, but you know, I didn't really like getting dropped like a sack on my bed. So, I'm feeling like taking a little payback." Ichiru's eyes widened when he tried to get away from under the other. Zero's thin fingers began to dance around Ichiru's rib cage. His muscles shook as Zero tickled him.

They both knew they were too old for childish games, but they played them anyway. No one ever said they had to act like adults all the time. After all, they were kids once as well.

"Ahh!!!! I give damnit!!!" Ichiru had tears in the corner of his eyes as he pushed Zero off with one final shove. He shakily took in slow breaths. He could still feel those fingers tickling him to almost death. "Damn-hehe-you! You know I'm sensitive as fuck!"

Zero laughed as his brother shivered. He leaned back onto the floor as he looked up into the ceiling. "I'm gonna go make some food okay?" Ichiru nodded as he watched his brother walk into the kitchen. Zero was an almost expert cook. He was gifted in many ways. He could tell if a fruit was better than the other with a single look.

A few minutes later, as Ichiru laid curled into his blanket, the phone rang. He groaned as he reached out of his warm cocoon and answered the phone with a professional voice.

"Hello, this is Kaien Cross from Rose Hospital, am I speaking with Zero?" Ichiru looked over to where Zero was occupied with making his brunch as perfect as possible. "He's busy right now, but I can take a message." The man on the other line clicked his tongue. "Alright then, tell him to be here tomorrow by 6 am. His schedule has been changed. He'll know what I'm talking about. Well then, that is all." And so, the man on the other line hung up.

Ichiru stood up from his little nest and walked over to Zero and sat across him. "You got a call." Zero looked at Ichiru as he put a piece of his scrambled eggs into his mouth. "Cross called to tell you that your surgery schedule has been changed and to be there by 6am." Zero swallowed his last bit of egg and drank some of his juice before speaking. "I see." He sighed and leaned back into his chair with a sort of relieved look on his face.

Before Ichiru could ask, Zero began to tell him. "I'm going to perform surgery on a little girl. About 6 or 8. She has a weak heart and it has taken almost two years to find a perfect match. I was supposed to do the surgery a week from now, but it looks like the organ made it here faster than we were expecting." Ichiru smiled. "That's great."

Zero shook his head and put it on the table. "If anything, and I mean anything, goes wrong, there's a probability of the kid dying. Since her heart is so small and weak, almost anything can go wrong. From blood loss to cardiac arrest. We have to make sure to keep her breathing properly or we might loose her."

Ichiru moved around the table and hugged his brother from behind. "You'll save her Zero. Why else would they trust you with such a life? It means that they believe you can save her."

Zero gave Ichiru a small smile and stood up. "I hope you're right. I'll try my hardest to get this done perfectly for her."

Uh…..I hope it was alright…And no, Zero and Ichiru don't have a sibling thing going on…like…no incest….nothing against it though. Sorry for them being OOC but this is Au so...yeah...it'll get better!!!

So, what did you guys think? Good, bad, ok, so so?
