I hope everyone who's reading this story stays with it. Thing don't start getting serious for quite a few chapters just so you know. And any questions are welcome. I would love any suggestions that anyone has. This is my first crossover fanfic so I'm still new to mixing worlds

I don't own any part of Naruto or Elfen Lied.

Problems and experiments

Tsunade growled angrily, thinking, Why does this have to happen to me. As soon as Naruto leaves all hell breaks loose. I've got every trader in the village, breathing down my neck about their stupid permits. I have the next chunin exams to arrange. I need to have the new construction project approved for Naruto by the time he gets back. And on top of it all, some psycho has started a killing spree. Tsunade fervently wished the Sixth Hokage were here. Even thought Naruto had little experience leading people or administrating, people bent over backwards to make things easy for him. If Naruto were here the only problem he would have would be choosing from the volunteers, who would run the Exams.

It had been a year since Naruto defeated Madara and Obito in the infamous battle with the Allied Shinobi Forces. He had lost his arm and many friends throughout the short, but bloody war. But he had been elevated to cult status. He was hailed as the hero of the world. If you asked anyone... anywhere... who was the most powerful shinobi alive. They would answer "Naruto Uzumaki". It ticked her off that he could sit back and people would scramble to do what he even suggested. If she wanted people to get things done she had to shout at the top of her lungs.

She looked to her right, "Shikamaru, could you possibly find someone to host the Chunin exams today. If you could do that I would be grateful. But Anko is unavailable for Second proctor so you'll need to find two people." He asked, "Where is she then?" Tsunade gritted her teeth, "She is trying to find the bastard who keeps ripping people apart! I can't believe this. The same day! the exact same day that our most powerful and influential fighter leaves, Bang!, suddenly we're dealing with a killer." Shizune said," We could always just request Naruto come back. We could easily get a message to him." Tsunade said, "No... I'll be damned if I ask for help from our 18 year old Hokage. Besides, he needed a break after his breakup with Hinata."

All three of them sighed. No one...in the entire land of Fire knew what had happened between Naruto and Hinata. And to any outward observer it seemed as though the heiress to the Hyuuga clan was still infatuated with Naruto. But everyone in the Leaf also knew that they had dated and then suddenly broke it off. Naruto and Hinata still spoke, they were still very friendly, and they even kissed occasionally. But whatever happened between them, they kept bars and chains over the whole thing. Naruto spoke often of Hinata, but never romantically. That same was true for her. Tsunade didn't know if they would ever get together again. At the moment Hinata was becoming the Hyuuga clan leader. At least it's second in command. Hiashi had admitted once or twice that Hinata was far better at solving problems than he was. And that he missed her advice when she wasn't around.

Naruto for his part had gone off to the land of lightening to train with Killer B and Yugito, The two and eight tailed beasts. His prosthetic arm had regained all the strength of the original and he was back to his peak again. She wondered what he was doing at the moment. Probably training till he drops or stuffing himself silly. That boy never changed.

Shikamaru startled her out of her thoughts, "I think that we should assign more people to the mission to find and eliminate this murderer. Whoever is doing this has the skill to evade Ambu." Tsunade said, "Don't bother. I've already assigned Yamato and Kurenai to it." Shikamaru asked, "Is it a good idea to give this kind of mission to Kurenai at the moment. This will be her first mission since getting pregnant." She knitted her fingers together. Tsunade said, "She'll be fine. I've instructed her to be careful. And with a baby she will be careful."

Anko crept through the abandoned house. It would have been dark, but a string of light on the ceiling provided dim lighting. Still, shadows hugged the floor and it was hard to see properly. The silence of the house was eerie. There were supposed to be five or six bandits living here. But as of yet they had found nothing. Anko sniffed the air and caught the nauseating scent of blood. Behind her Hanna gasped, muttering something under her breath.

The door to her left opened slowly, creaking on rusted hinges. She pulled it open. It had been sealed tighter than it should have. The smell of blood grew thicker. Anko reached in and flicked the switch for the lights. Behind her Hanna swallowed loudly. The single bare bulb illuminated a scene of carnage. Five bodies lay...in various stages of dismemberment. Limbs were distributed liberally over the floor and blood covered every inch of the floor. Not to mention a good portion of the walls. There was no sign of a struggle. It looked like these people had been torn apart before they realized what happened.

The three Ambu entered the room slowly, making sure it wasn't an ambush. Hanna checked the bodies. She said, "Two days old. That man misled us. He said there were screams coming from here last night. Yamato said, "Look here." He was standing in another open door way. Anko entered. There was one body inside. A bandit by the look of him. He was missing both arms and his throat was gone. Anko grimaced. The rest of the small room was seemingly untouched. A twin-size bed was in the corner with the blankets folded crisply. Hanna checked it. She said, "Someone slept here last night. I would say the person were tracking is young and female. "

Yamato asked, "Could a young girl do this. I mean sure there are plenty of kunoichi physically capable of killing six bandits without attracting attention, but how many would kill them and then sleep in the same room with a corpse?" Hanna shivered, "Yeah I hear you there. I'm an Ambu, but I couldn't sleep in the same room with someone I killed." Anko asked, "Hanna can you track her scent?" The Inuzuka sniffed the air. She said, "I can't tell in here with all this blood. Let's go outside."

Outside it was dark and wet. A recent rain had dampened the ground outside. Hanna checked the surrounding ground for footprints then concentrated her chakra in her nose. She took a long sniff of the air. She looked to her left, "This way!" They rushed through the trees. Anko kept to the back, watching their rear. They couldn't afford to be careless. This murder was responsible for many deaths in the area. Granted most of those who were killed were bandits or civilians, but to do this much damage without detection required skill. This wasn't even taking into account the way the victims were killed. Ripped apart, not cut or stabbed or burned. Torn to shreds, disemboweled. Every victim was killed in a similar manner. It either meant that the killer was doing it on purpose...or...he or she had a particular method of attacking that did sever damage to the opponent's body.

It started to rain as the jumped through the trees along the trail after Hanna. She led them on a winding course through the dense foliage. Anko realized that they were getting very close to a small village to the east of the Leaf Village. She prayed that the killer hadn't decided on a bigger target this time.

Thirty minutes of careful tracking later the trail ran cold. Hanna suddenly stopped. She said, "Scent stops dead right here." Anko cursed under her breath. She hissed, "It's like she's teasing us with an easy trail and then dropping off our scanners...right into town. Yamato, Do you think that our killer is still in the village?" Yamato asked Hanna, "How old is the scent right here?" She bent down to examine the ground. She pinched the dirt beneath her fingers and sniffed. She said, "No more than a day. Possible less than eight hours considering this rain." Yamato said, "Then we go into town. I have instructed my wood clone to tell Kurenai to meet us here. She will be here any minute."

A moment later Kurenai landed next to them. She asked, "What did you find? Is she in this village?" Hanna said, "We found that shack just like the man said. Six bandits torn to pieces and one neatly made bed. Out killer killed them and then had a nap before coming here through the forest." Anko added, "We have evidence that supports the killer being a young female. Other than that we still have no clue who it is." The four of them agreed to head on into the village on two groups. Hanna with Kurenai and Anko with Yamato. They entered the village from either side.

Hanna scratch her cheek. She walked through the village. It seemed strange. even though it was raining lightly, there were still many people up and walking around. Kurenai kept an eye out as Hanna questioned a vendor. The old man said that he hadn't seen anyone overly suspicions. However he remarked that people seemed unhappy lately, especially this strange young girl with pink hair. The man said, "I think it's with all the killings that have been happening lately. It makes you wonder who could evade the authorities so long. Perhaps the atkuski aren't all gone...?"

With that disturbing talk over with, Hanna left the small stall. She whispered in Kurenai's ear, "That's the fifth person who's basically said that everyone is nervous or grieving. A lot of people have died. Half the village has had relatives killed." Kurenai said, "I hope Yamato and Anko have had better luck.

Yamato finished talking to the young girl about the same time Anko walked out of the shop. He asked, "Find anything?" "No" Her face was a mask of disappointment. It was becoming clear to both of them that the likelihood of finding their target was small unless she made a move while they were near. Anko asked, "You learn anything from that girl?" Yamato looked behind him. A tall girl with long pink hair walked through the rain away from them. It looked like she was wearing a head band of some sort. He said, "She didn't know anything, but I think she lost someone. She looks like she's all alone. Might have lost her family or friends to the killer." Anko cursed, "Shit! We're stumbling around in the dark." She sighed, "Let's go meet up with the others, maybe they found something.

Hanna and Kurenai were sitting at chairs at an outside restaurant's seats. They looked just as dejected. As soon as they got close Hanna's gaze snapped up to them. Her tone was oddly excited, "You found something?!" Yamato shook his head. She jumped up, "But you must have met out target, you both smell like the bed back at the abandoned shack!" Anko tried to remember if any of the people looked suspicious to her. She said, "I don't recall hearing any implausible stories or meeting any suspicious people. And I can tell if someone is lying to me. It must have been Yamato." Yamato thought, I didn't meet anyone out of the ordinary. And I must have talked to twenty or thirty people on the street, so I have no clue which was our target. He was forced to admit defeat. "I have no idea who it was. They all seemed genuine to me, but I'm not an interrogator."

Hanna grabbed fistfuls of her hair, "Grrrr! Why can't we find one damn person after a month of searching!?"

Back at the Hidden cloud village Naruto was perfecting his latest move. With the aid of Yugito and a rather miffed Killer B. Killer B was miffed, of course, because the concert he had planed had been crashed...spectacularly. B had been preparing for two hours, getting his concert ready. Naruto and Yugito, against their better judgment had come to help near the end. One of B's helpers wanted to see the jutsue that Naruto had been working on. Naruto had agreed to display his new move. Unfortunately things had gone amiss and his demonstration destroyed the entire stage.

Therefore B had dedicated the time he would have spent rapping, teaching Naruto better control. The problem was, that B had good control, but he didn't have any talent controlling nature chakra. Naruto had learned to fashion arms out of his Ninetails chakra shortly before the fourth great shinobi war. After mastering that ability he got the idea of using nature chakra to fashion the same arms without using his own power. But it was a lot trickier in practice than it was in theory. For starters it took a massive amount of concentration to make the nature chakra dense enough to affect the world around him. And then there was the additional problem of manipulating the same chakra several different ways at once. Using nature chakra was almost as difficult as mastering Rasengan.

Naruto sat still, he with two other clones helping. His first clone gathered Nature energy from all around them, funneling it through the second clone. The second clone formed dense, but invisible, chakra arms. Finally, Naruto himself used these arms to move objects. He was not ready to attempt a Rasengan again. Killer B was also training. He had developed his ability to sense Nature energy, but he still couldn't gather it. Yugito developed a training exercise. Killer B would hone his Nature sensing ability by dodging Naruto's chakra arms, while Naruto honed his own skill by trying to catch B.

There was an added bonus for Yugito. She was able to watch B get smacked around by thin air. Because as of yet, he was far better at sensing than dodging. Naruto could manage a maximum of three chakra arms out to a distance of about ten feet without them falling apart. He was learning the hard way that Nature chakra was even more volatile than demonic chakra. At least when he was drawing on Kurama's power he didn't have to worry about the number of plants or animals in the area. If the area they trained in was barren, it made it a lot harder to gather nature energy. Naruto guessed that was because living things had more energy stored in them that inanimate objects.

Killer B dodged his latest sweep of his chakra arms by falling flat. Naruto swung one arm down to smash B, but he was able to roll to the side in time. He got to his feet, grumbling about not being able to see what he was dodging. Naruto decided to end the current fight. All three arms swung in at once. One from either side and one on the top. Killer B thought, Now that's no fair..." WHAM! The impact knocked B flying.

Naruto let his clones disperse and walked over to help Killer B up. The older jinchuriki dusted himself off, saying, "Man Naruto...those chakra arms of yours sure do pack a punch...and now that I've felt them, it's time to have lunch! weeeyah!" Yugito smirked as they approached. She asked, "So how long before you will be able to use those in a battle?" Naruto shrugged. If I use my mass clone training technique...um...I'd say I could have it down in a week." Killer B shook his head, "I still don't get how you can be so legit...and yet still be a little shit...him nope. That doesn't work." Naruto and Yugito looked at each other in amusement as B took out his notebook. He scribbled a note into it and then snapped it close. He asked, "So..uh...where shall we go to eat?"

The Sixth Hokage grinned, "I could always just flash us back to the Leaf for some Ichiraku..." Yugito let out a bark of laughter. "Ha, that's an Idea! How about we do that! I've never eaten at Ichiraku." Naruto waived his hands back and forth, "Wait...Wait! I was just kidding." Yugito said, "Oh no. You offered and we're going!" She saw the look on his face. "Oh don't worry, We will pitch in so you don't have to take us all the way there on your own steam." B said, "Yeah!... ya know Naruto, I really like that girl who works there. She takes the time to listen to my rhymes. What was her name again?" Naruto said, Oh you mean Ayame...!"

B rubbed his stomach, "Well anyway, Let's get going ya fools!"

Just so we're clear. Naruto could flash between the village and the hidden Cloud a thousand times, but he usually uses his own chakra because Kurama still takes a very dim view of Naruto wasting his chakra. Kurama also rarely talks to Naruto except in special circumstances.

Anyway I'd love more reviews so thanks for reading!
