Chapter 1

Lab rat and the escape

The boy was sitting in his apartment's bathroom washing his face with cold water and clenching his fists, trying to ease the never-ening pain.

He was the only survivor of Orochimaru's latest experiment; no one knew his real name so he was named after the project: Rikudou. Orochimaru burned his village, which he of course found out much later by eavesdropping on two jounins conversation, and then came to him offering protection, which he really needed at that point. He was put through torture beyond belief, surprising Orochimaru with his pain endurance and sheer will. That ended up being a bad thing when Orochimaru put him through his newest and most dangerous experiment.

That was a week ago, at that moment the pain felt almost impossible to bear, making the torture look child's play. Imagine Orochimaru and Kabuto's surprise when he, of all the 50 subjects was able to survive and actually USE the powers the experiment granted him! He didn't know much, except that the experiment gave infinite chakra called "Youki" and, although not part of the plan, also gave him some strange eyes that, although made him much more powerful, enraged him to no end!

As a kid, everyone stood away from him because of his purple eyes and now they went ahead and made frickin' circles on his eyes. The only kid that ever played with him he met two weeks before the experiment. "Those were the first times I really smiled of happiness" he thought remembering…

Flashback

The sun was shining brightly, too brightly if we were to ask a certain slave and his "classmates" that were carrying a boulder up a mountain.

The officers said this was training, but everyone knew it was just torture, but that didn't stop them in the least, the ones who were alive were used to harder especially a certain purple-eyed carbon black-haired teenager, the "Purple-eyed freak" as they knew he was called before. He actually felt more at home here than in his village, here they were all strange- no special as Orochimaru said.

Although they were used to doing this, many started feeling tired, this hill was bigger than usual, 20 times bigger as-a-matter-of-fact so many were about to fall. What they heard next was what always sounded strange but they were getting used to it:

-Leave the boulder to me guys, go rest! the purple eyed freak said with a grin that was turning in a smile. Although he said it smiling they knew it wasn't a request but a command, and they were happy to oblige, at least until a girl came to them mumbling something around the lines of "I see"..

-I'm pretty sure this was a task for all the slaves, so there is nothing you get if you do it alone and out of all the higher ups I'm the only one who thinks about this, let alone come all the way up here to see it, so why do you do it? It makes no sense, you get nothing out of it, and only helps you look weak because you'll be panting like you ran for 4 hours straight, so why do you do it?! She exclaimed waving her hand like she was giving an emotional speech.

-So you must be the girl that's been stalking me for the last 2 days? He said eye-smiling, her widened eyes were enough of an answer. You are Guren-san sister, aren't you? When Garon-chan, the girl who's crystal jutsu is more powerful than her sister's and who has the potential to become more powerful than the all the kages at one place stalks me I should feel honored. And besides, I need to become powerful and this is good training.

The girl was completely taken aback by what he knew and blinked a few times when he talked about her abilities, she had no idea what he was talking about, sure she beat her sister lots of times, but she was no where near Orochimaru's level, let alone the kage's especially all at the same time, or so she thought. "I never saw Orochimaru-sama fight though…" , maybe she was overestimating him? The last part of the boy's speech left her frozen though, he saw the kid doing what he was doing now two days ago and watched him, pausing only to sleep, that was for way to few hours as it was anyway, and now she discovers he knew the whole time? She couldn't believe it, she expected her sister to see her, not only did they think the same most of the time but she was always watching her, so when she asked her last night she responded that he was strange and different "maybe a little handsome too…" she shook her thoughts away, she didn't know where that came from and didn't want to know.

She went back to wondering what was wrong with her, she knew all the jutsus the clan had and invented some of her own, mastering each of them in a few hours, but now she hit a wall, she didn't know what to do next, she wasn't improving no matter what training she would do, and what was left to improve anyway? She was already doing them without handseals or having to shout them, so she was pretty much a master over crystal, maybe a slave was more creative than her...

-Could you please help me with my training? I'm not too creative and since you train a lot you might be able to help me. Ahhh…

-It's Rikudou, and sure Garon-chan I'd be happy to, and I have a few ideas anyway!

Flashback End

After that he trained her to use her crystal by studying the Ichibi's sand control, needless to say Guren and Orochimaru were scared out of their mind when they saw how easy the crystal was flying around her. One day, she defeated Guren in a few seconds before challenging Orochimaru. He tried to attack before she could get in position, but crashed head-on in a crystal wall, which strangely fell over him covering his hands and restraining him while the girl held 2 blades from crystal she could decapitate him with in a second. The poor bastard actually lost the battle and would have been killed were it a deathmatch. He was heavily praised by the losers and so he continued training her. He taught her the basic tree and water walking, and used the chakra paper to learn what her affinity was, apparently water.

The experiment happened the next day, and during the next week, even if he was in a critical condition, he taught her all he knew about suiton jutsus including two of those: Water Prison Technique (1) and Water Clone Technique (2). In that time she also helped him develop his new eyes power, called the Rinnegan(3).

The Rinnegan was doing well, the youki however was simply wild, and also heavily reacting to emotion seeing as he somehow grew a tail when he found out that Orochimaru was intending to take Garon's body as his next host and kill Rikudou as he was getting too powerful. So they decided to escape . Before making an escape plan he told her about his training before he met Orochimaru .

-My family had this huge jutsu library, it contained hundreds of scrolls, but since I learned kage bunshin and had an amazing chakra level, I simply created a thousand clone in a day, and the memories I got from them I put in practice. It took me 3 full years but I was able to learn them all, mastering at least one of each. Afterwords I began training my taijutsu, I practiced from 5:00 am until 10:00 pm with only two breaks, someone called me the "new Maito Gai" but I never got to know what that meant, but I heard he was a guy who trained with weights so I made some chakra seals myself. Sealing was natural cuz' my grandgranddad made 3 important scrolls for Konoha that it still has. As I was telling you, I also got combat experience from fighting m-my Ka … Kage … Bunshin …He started babbling when an amazing idea hit him: A diversion made by Kage Bunshins helped by some well-placed explosive tags and a few seals would be able to draw Orochimaru's attention for a few hours and kill hundreds of his Oto-nin's in the meantime, heck with a well done strategy he could make Orochimaru flee and save the slaves! He turned his eyes to the girl, frowning before giving her a description of the plan.

-Garon, Here's the plan: I will use an army of kage bunshins for which I'll need identities so I need to get an encyclopedia with personalities, Orochimaru must have some, just tell him you're curious and give it to me as soon as you get it, I'll make a copy of each strong guy I find and get my clones to learn their jutsus, the Oto guys won't know the difference, and then we will set off explosive tags all across the hideout, They won't know what hit them, we will strike tomorrow, meet me here at dawn, take a backpack with everything you need, which musn't be too much. He added remembering Orochimaru told him that girls of her age tend to take dresses and make-up as needed in life-or-death situations.

Getting the idea, she threw him a glance which made the old saying "If looks could kill" way worse than imagined.

-I'm not some stupid fan girl! (¾ of Konoha's woman population sneezed)I'm as trained as you baka! She exploded, sending shivers through every living being on 1 mile distance. I can pack only what's need alright! She said clearly forcing herself to calm down

He just sighed; he will probably have to live with this girl for the next few years and he hoped he will slowly begin to understand how she can turn from cold-blooded to banshee and back in 5 seconds.

-You better not alert Guren-san, I know it's hard but we are on enemy territory, and we have no friends that wouldn't sell us out for a nice bed. He said sadly. He knew they never had friends but Garon always had her sister, which she was now forced to leave, knowing her only support might be killed in the crossover. He wasn't going to force this issue further, for it would only hurt more, and even if it wouldn't he didn't know what to say. He heard of girls forced to leave their sisters, heck he could count at least 10 girls of that kind he met, bet they were usually hated or charring corpses so the girls were getting past it; put this wasn't so easy. She loved her sister, and even if ordered wouldn't be able to kill her, let alone leave her in an S-level battle she had no chance of winning, especially when she could stop it with one word: "no", that was all that would be needed to convince him to make a different plan, where no casualties we're involved

-Don't worry, she won't know until it's too late. She said trying to look confident.

"I won't back down, besides she can take care of herself, right…?"She thought, her confidence fluctuating. Should she try to stop him? No, that would not only force them to waste time planning but they also couldn't save the slaves any other way, and it was good payback losing all his soldiers for what he tried to do, maybe he could actually be killed in the attack!

-Then you should go pack, then take that encyclopedia, I will need time after all! He said careful not to sound too comenting, he had to pack too!

She carefully left, showing an evil smirk on her face, that snake was sogoing to pay for this, she decided to place some diamond seals in his lab, it's not like she could do much with a seal that had a thermal sensor and threw spikes all over the place, she was going to make it look like she fought to the death, and that stupid snake will believe it.

Only then did she notice she was going to her room mumbling and with an evil grin like she killed someone and no one had any proof it was her. She shook her head; she was way too ruthless, no matter what they'll do after this, even most missing-nin killed everyone they fought, they tortured, robbed and raped of course, but they usually did it cause they were in a bad mood not because that was in their nature. The thought of "what we will do" came only now, and she was actually wondering, "Will it be we? Will we just go to the nearest village and disperse? That would be ruthless but he did spend 4 years as a slave under the most ruthless madman didn't he ?And under his tutelage after his second year nonetheless!" She thought gulping, he did endure worse, but she didn't! She will die in a few days without him and his street-wises! "He wouldn't do that, would he? And if he won't I will be a burden, maybe he will need me as a bodyguard! Or will pay me to assassinate and so on! That would be enough for a living…"Her evil smirk became a shocked look, followed by a sad one and finally a sad smile. She quickly packed some clothes, took quite a sum of money from her sister, something around 10.700.000 ryo, not that she knew how much that was, but it sounded enough for at least a month with as much food as she needed to get.

She then ran to Orochimaru's lab, which wasn't something new, so nobody got any suspicions. As she entered she decided she might as well ask her sister since the snake was in the middle of an experiment:

-Guren-nee-chan, where do you think I could find an encyclopedia with personalities? Rikudou-kun wants to teach me some history and said I should learn some important characters. She said, she only called him "-Kun" when near her sister, "I can't call him like that directly, though he calls me "Chan", I just am not bold enough"

- Just take one from over there Garon. She said bluntly, she was embarrassed of the difference in power between them. "It's strange that Garon, who wouldn't open a book if her life was on the line, was convinced to study by a kid she met 3 weeks ago." She thought frowning. There was something about that kid that gave her a bad feeling, but she chose to ignore it.

Garon gave the book to Rikudou and left to sleep, she had some long days ahead of her.
