Chapter 1 ~ Adapt to a New World

Jio Freed's PoV

I was watching a battle of giant frogs and a fifteen-year-old blonde haired guy (called Naruto) fighting against some guys from an organization called Akatsuki (who all had orange hair and too many piercings) in the middle of a crater which looked like it was made by a meteor. The audience around me consisted of a group of ninjas who didn't help the aforementioned fifteen year old, including my new-found tour guide Shikamaru Nara. As I was watching the fight progress, I was trying to remember how I got mixed up in this whole mess in the first place. Slumping against a piece of rubble, I remembered how it all started …

FLASHBACK

I opened my eyes to see white everywhere. What's going on? I had just gotten rid of Satan and stopped him from taking over both me and the world. Soo, why can't I see a thing? Slowly, the whiteness disappeared, and I found that I was sitting at the edge of a village on a rooftop. Woah, where am I? Was I back on Earth? I don't know this place though. Maybe I'm in Eden? Nah, that's impossible. Lucifer told me that Eden had been destroyed. Ahh, for god's sake, nothing's going to happen if all I do is think. Frustrated and confused, I stood up and tried to get a feeling of my surroundings. Well, thats what I tried to do. The only thing I saw was a village being blown-up by some sort of explosion, and I was knocked of the rooftop by a strong gust of wind. Then everything around me collapsed.

So much for getting a sense of my suroundings. Wait, what the hell just happened? I mean, the entire village that I was looking at had been destroyed, and now all that was left was a thin strip of ruble pushed up against the villages' wall. That's where I was, underneath a bunch of collapsed buildings. It took me a good five minutes to try and get myself out from underneath all the junk. Oo-kay, what have I gotten myself into this time? I guess the real question is what am I going to do now. Most of the people who were in this village should have died. I sighed. What else was there to do? I had no clue where I was, and now I was in the middle of some sort of conflict.

Finally, I decided that I might as well go and see if I could find anyone and then ask them some questions. After checking to see whether I had any life-threatening injuries I stood up, made sure I had my O-part Zero, and started to look for survivors. It was really hard to see because the dust and sand was still blowing all over the place, but eventually I stumbled across a girl and a … slug! Shrugging off the surprise, I walked towards the girl. She had pink hair and seemed to be around the age of fifteen, and also appeared to be in shock. Guess the explosion certainly wasn't expected. But are they ever?

"Umm, hello?" I tentatively called out to her.

"Huh?" Turning around, she caught sight of me. Roughly wiping away tears, she seemed to pull herself together and began asking abunch of questions. "Are you hurt anywhere? Have you seen any people in need of healing? Why aren't you with the rest of the people who evacuated? Do -"

"Woah, hold on." I inturrupted her before any other questions came out. "First of all, yes, I'm fine. Second of all, I was looking for people, and you're the first I've seen." I was surprised at the last question. I mean, evacuation? Did it mean that they were expecting this? Choosing not to answer that question, I continued. "I had some questions to ask. Would you mind telling me what the hell is going on?"

"We're being attacked again." Again! She acts as if I should have known. "As soon as I've taken a look at you, please leave Konoha and wait in a safe place. I'm sure some ninja's will tell you where to go." Turning towards the slug, she asked "Lady Katsuyu, do you have any chakra left? I'll need to borrow some." The slug, which my I add was bigger than the girl, replied, "No, not much. Tsunade-sama has exhausted most of her chakra. I can still give you some of my own, though, Sakura."

Konoha, chakra, ninjas, talking slugs? Evacuation? Attacked again? I deducted that the girls name is Sakura, the slugs' Katsuyu, and that this place is called Konoha. But what about everything else? I decided to clear some things up. "Umm, sorry, but where are we? All I know is that some sort of explosion went off."

The girl Sakura seemed surprise. "So you aren't a civilian? Are you a traveler from another nation of something? You sure came at a bad time. Akatsuki just attacked the village. Our hokage, Tsunade-sama, did everything she could to help us and save people, but this is how things turned out. I'm not so much worried about those with Lady Katsuyu, but not everyone has her and many people must have died in battle before this explosion."

Ahhh, so there was a battle before this. Makes sense. Not really. I was still majorly confused. "How does the fact that this slug is with other people make you worry less? And how can this slug be in so many places at once in the first place?"

Sakura gave me an angry look then glanced worriedly at the slug. "Don't worry," the slug Katsuyu said to Sakura, seeing her expression. Turning her head to me, she explained,"Well, I'm a healer, and during the explosion I absorbed people into my body to protect them from harm. I am originally alot bigger than this, but Lady Tsunade, who is my 'master' I guess, split me with a jutsu so that I could be in many places at the same time. Sakura is saying that if one of me is with a person, then I can help heal previous wounds that they might have had."

Ahhh, that explains everything. NOT. "Listen, I'm not understanding a thing, so if you could just tell me what I could do to help or where to go, I'll just be on my way." I figured I won't get any info on what's happening, so instead I'll find someone who can won't question me and just let me do something.

"Fine. Go find some ninja's and they'll deal with you. If you don't need any wounds healed, then I'll go help people who need it. Let's go, Lady Katsuyu."

"Yes" the slug replied.

"Oh, by the way," the Sakura girl paused and looked at me. "What's your name?"

"Jio Freed, why?"

"If you meet any ninja's, just say that Sakura told you that you could help. You don't seem like an enemy, so I'll let you help around. We're short on hands in any case. Well then, bye!"

Well, at least she looks like she's in a better mood then when I first found her. Hold on a sec, she never ended up taking a look at me. Ah, whatever, might as well go closer to the crater and see what's going on.

This is how I came to meet Skikamaru Nara. Glancing towards the mentioned individual, I wondered if all ninja's were like him. He was sitting and leaning against a piece of a building remnant since his right leg was broken. The fifteen year old had black hair tied back in a high pony tail, wore a green vest and had a piercing in each ear. He also had a band that was tied around his upper arm, which had a metal piece with a strange symbol on it. It was like a leaf with a swirl in the middle.

With him was his father, Shikaku Nara, who was also a ninja and looked almost identical to his son other than the fact that he looked older, had a beard and several of scars on his face. Our third member was Shiho. She was a cryptology expert and part of Konoha's Cryptology Unit. She had messy blonde hair worn in a low pony tail, wore glasses and the same type of lab coat on as did the human Lucifer in his memories. Also, we had two Katsuyu slugs. I learned that they can communicate with the other slugs (Since technically they are one slug). That's how we learned that it was Naruto fighting the Akatsuki guys called Pain. That's also how we learned that Naruto didn't want any help with the fight; because he thought that we would just get in the way.

Since it's not any of my business anyways, I didn't do anything, especially since the Naruto kid was beating one Pain at a time. Shikamaru had guessed that the Pain guys were after Naruto, but he was holding out pretty well at the moment. I decided to stick with Shikamaru for as long as I could, and just observe and see what's happening instead of getting involved more than I already was. After things cool down, I figured there'll be a better chance to sort out everything. Well, that's what I thought until I heard what comments I got from another ninja who saw me.

You see, thing is, all the people up 'till now whom I've meet all had more important things to do than to comment about my looks. I knew that I looked out of place with my long, trailing red scarf, half black half white hair with miss-matched eyes, one being red and the other being blue. My clothing was also miss-matched. Half my coat was black and the other white, along with my shoes. My pants were all black with only a white stripe down the side, though. On one hand, I have a 666 mark from Satan, as well as Ruby's O-Part imbedded in my other hand. The first to care about my looks was a ninja girl named Ino Yamanaka. When she and her group came, the first thing she said was "Hi Shikamaru, there's somethi- What's with the freak beside you?" Great first impression if you want people to like you, right? That's what I thought as well. It took some work on Shikamaru's part to convince her that I'm an ally and that I could be useful. At this point, I vowed to prove her wrong about me being a freak, and make her think that I had a use.

"Speaking of useful, what can you do, Jio?" Shikamaru asked as he turned towards me.

"Well…" I looked around at the group. We now had a group of seven, one whom was unconscious. "Long story short, I have no clue what's going on, so right now I'm planning on doing what I can and helping around until I can understand where I am and how to get back to where I'm from".

Ino's father, Inochi Yamanaka, replied, "We would gladly help you, except you can see the situation that we're currently in. I guess you can help us with some things." Turning towards the group, he started to say what he came here for.

"Shizune," he started to say, while waving towards the unconscious person, "she figured out a lot during the autopsy of one of Pains' bodies. She told us all she knew, but got killed by one of the Pains." Oh, so she was dead. "This is what she figured out: ends up that the metal in each of the Pain's bodies is a chakra receiver, which lets …"

Inochi continued and explained the findings, more than half of which I didn't understand. Chakra, what it can do, jutsus and everything of the like that he mentioned went through one ear and out the other. If they had been talking about O-Parts and O.P.T.'s, angel and demon recipes, or the Kabbalahs, I would have understood. But alas, they weren't, so I just sat down and waited until I could do something useful. I was wondering off in my own world, thinking about Ruby and how she would react in this type of situation. I sighed. If only she were here, I wouldn't have felt so useless. Why can't an eighteen year old like me help in some way?

"I see… so that's how things happened" Shikamaru had said after the complicated explanation was done.

"If we had been more diligent, this would never have …" Ino started to say about Shizune's death, almost in tears.

"We can't let her death be in vain," Shikamaru interrupted her. "We'll unravel the mystery she tried to solve, and find the real Pain. You call whine after this is all over!"

"Shikamaru, can't you say it to her nicer?" his father remarked.

"No, he is right, Shikaku," answered the girl's father. "The way to make ourselves useful is to find the location of the real Pain as soon as possible. "

At this point, they started to talk about jutsus and chakra frequencies and all that complicated stuff again. After finally finding a solution, they turned towards the slug and said "Katsuyu, could you please tell all the able survivors that we need their help to look for the real Pain." Turning to me, Inochi said," You can help us with the search as w-"

A huge pressure came out of nowhere. Looking towards the crater, I saw a beam of red reaching towards the sky, and the Naruto kid was gone, replaced by some red human/fox thing. Water started coming out of the ground at the bottom of the crater, and there was an unconscious girl beside it (At least, I hoped she was unconscious). The red thing jumped away, and after it went the last Pain. Everyone was wondering what was happening. In time, the slugs told us that the village was beyond recognizable (As if it wasn't before, I had thought) and that everyone needed to evacuate.

"This is due to Naruto's Kyuubi power," continued the slug. "I know because my clone is attacked to him."

"He transformed into the Kyuubi, huh. This is troublesome." remarked Shikamaru. Is this Kyuubi another jutsu thing I wonder? And is it a big deal? I mean, Shikamaru thinks everything is annoying, so I'm not quite sure how serious this is.

"But Yamamoto and Kakashi should have should have placed a Sealing Jutsu on him! How did this happen?" Inochi exclaimed. No, it doesn't look like a jutsu. Maybe he has something inside him like I do?

"It was Hinata," the slug explained in a worried tone. So that's who the unconscious girl was. "She tried to save Naruto and was taken down right in front of him. And then Naruto …"

"So that's what triggered the transformation, huh?" Shikamaru finished for the slug.

"Hold on a minute, that Naruto kid has something in him as well?" What was happening to Naruto sounded almost what happened with me. When I got over emotional, I turned into Satan.

"What do you mean, 'as well', Jio?" Shikamaru asked.

I hesitated. I didn't want to say anything about Satan, but It seemed like they wouldn't spill their info if I didn't first.

"Well, I have a demon called Satan, also known as Lucifer, in me. Sometimes when I get emotional I would transform into him and look like him. It sounded kind of what Naruto is going through. Although when I transform completely, I don't remember what happens during that time because Satan takes over my consciousness. But when I just use his powers I simply look like him and have my own mind." After a small pause, I added, "I also transform into him completely when I'm low on spirit energy. He takes the opportunity to take over me.

This proclamation was met with silence and side glances from everyone in the group. I was afraid that I had said something over-the-top when Shikamaru said, "Well, since your situation sounds just about identical to Naruto's, I guess we can tell you a bit about him." Before continuing, he made sure everyone agreed with his judgment, and then continued.

"Basically, Naruto is exactly in the same boat as you are. He has a bijuu sealed in him, called the Kyuubi. When Naruto transforms, he starts to grow tails. After the third tail he loses his consciousness and goes wild. The most tails he's had so far is four. Yamamoto and Kakashi can usually stop the transformation, but they don't seem to be close to Naruto at the moment. Well," Shikamaru said, getting back to business, "all we can do if find all the survivors so that we can find the real Pain. Jio, you stay here with me and Shiho and we'll wait for more news before we decided what to do with you. During this time, I can get to learn more about what you can do and how you can help us."

Everyone seemed in agreement and split up. I sat down beside Shikamaru, readying myself for any questions he might ask. Would it be about my past? Where I came from? My powers? Hopefully, he didn't go too far. I don't need to be reminded of loosing Ruby again. I wonder where Ruby us now?

Steeling myself for the questions, I relazed and said, "Well, you can ask whenever you're ready."

"Well then …"

Authors Rant: I had a great idea for a story, and just started typing it, really. Since this is my first-ish fanfic, I'm trying to stay close to the storyline until I get more ideas.

Please, please review. Constructive critisism is the best. Thank you before hand the people who took the time out of their busy scheduals to read this long, not very-well written chapter. Greatly apreciated.
