After lunch they took Sara to the hospital of the Hidden Leaf. It was the first time Sara got to take a look in a small part of the village with such typical bright colored buildings. When she past the police station Sara stopped for a second. "Police station?" Sara asked out lout. She was told there was no police force in this village and yet there was a station named like one.

"Ah yes, we had a police force in this village a few years ago. It was founded by the second Hokage. But it took a downfall. It's been empty since." One of the two shinobi told Sara who was escorting her to the hospital. Sara decided not to ask about it. A story for another time.

People on the streets looked curiously at Sara. Even though she wasn't in her police uniform anymore, they still looked at her like she didn't belong here. Perhaps everyone already knew she was new here, or it was because she got guiduance from two shinobi guards. However Sara was relieved to see these people, especially because they weren't dressed as ninja's for a change. So there were actually normal people living in this place. Probably the people that the shinobi needed to protect.

It was only a short walk, but the fresh air did Sara some good. Sara got new energy and felt exited when she was waiting in one of the examination rooms of the hospital. She knew they were going to test her chakra, whatever that was. But something told Sara it was the source of Yamato's wooden jutsu powers and why that kid was walking on water. Would she be able to do such things as well in this world? How cool would that be?

A young woman walked in and introduced herself as Sakura. She will be guiding Sara trough all the test they wanted to do on her. She seemed nice. "Don't worry, none of the test will hurt. It's just a few simple tests to examine if your body is any different than the people in our world and some test to examine your chakra usage." Sakura explained.

Sara already learned that her chakra level was very low, but apparently these people were convinced she had at least some chakra inside of her.

"What does chakra do?" Sara asked Sakura.

"You don't know?" Sakura was confused for a moment. "Of course, I forgot you are from a world were people don't use chakra. Inoichi told me some things about it. It's hard for me to imagine."

Sara thought about it. "Actually, I have heard of it, but more in a spiritual way. Like something that doesn't really exists. At least no one in my world can use it for walking on water. Is that what chakra does in this world? Is it a form of energy that allows you to have crazy powers?"

"I see you figured out a lot already. Yes it's a form of energy. Depending on the chakra nature, the amount of chakra and the level of chakra control, shinobi can use different type of skills." Sakura explained.

"Chakra nature..? Ah never mind, thanks. I think I understand a bit. The rest will follow some other time." Sara gave Sakura a little smile. She needed to accept that there were a lot of things she wouldn't understand yet. It would take to much time to learn it all in one day.

Meanwhile in Tsunade's office Inoichi reported his findings. "I compared her test results with the average shinobi, since she's like a shinobi in her world." Inoichi explained while Tsunade read the report with scores on different aspects of Sara's psychological test.

"Hmm, her scores are pretty good." Tsunade sounded surprised.

"She has very stable emotions, keeps functioning in high stressful situations and past events shows that she learns quickly from her mistakes. If she had any talents, she would have been ANBU material with these scores." Inoicho said dead serious.

"Are you sure?" Tsunade asked doubting his conclusion.

"Like all psychological tests it should be wise to test this out in the field of course."

Tsunade kept reading. "analyzing skills and intelligence are also very high. These are Kakashi's level?"

"Correct. But her lack of knowledge about this world will still give her a big disadvantage." Inoichi pointed out. "Besides, this all won't matter much since her chakra is so low. Her skills might have been enough in her world.. but in ours, she won't last very long. Not without her gadgets that are now al broken or empty."

Tsunade agreed. "So far she got lucky. I wonder what Sakura's test will teach us about her chakra usage. Perhaps she'll have another surprise for us. Otherwise we'll need to find her another purpose in her new life."

"Might be for the best, even if she would train every day, she'll never get to the level of other shinobi on her age. She's too far behind."

"You're probably right." Tsunade sighted. "Oh and Inoichi, before you go. Did Sara ask you about how to get back to her world?"

"Surprisingly no. She seemed to have dropped that subject for now."

Meantime in the hospital Sakura started her tests on Sara.

"Well I must say I've never seen anything like this." Sakura told Sara while looking at the scan monitor showing Sara's chakra flow. "Your vitals are normal, you're healthy and yet your chakra is extremely low."

Sakura thought about what test to do next. "Uhm lets see. I think it's best to go to the treadmill first. See how much chakra your body uses in the first place."

"Uh okay." Sara wasn't looking forward to run on a treadmill, but luckily it didn't take very long.

"You can't run very fast considering you do seem fit." Sakura said, "but you didn't use any chakra while doing so."

Sara was offended, "didn't... run... fast?" she said out of breath. "I really... tried.. you know?"

"Even a novice shinobi could run all day in your speed." Sakura stated.

"Do you guys use chakra when running then?" Sara asked, her words coming out normal again. She always restored fast after work-outs. Ready to face the next ordeal.

"With that speed only a little, but always some. For example if I had your chakra level, I wouldn't even be able to walk.

For Sara it was hard to imagine how that felt like. "Will that happen to me if my chakra will get lower?"

Sakura picked up the chard that obtained all her notes. "We are going to find out next."

A little later Sara was hooked up to the same machine as the first one that could show her chakra flow. Sakura explained. "I have the ability to transfer chakra. I will slowly drain you and watch the monitor at the same time. If you start feeling sick, you'll have to tell me."

"Alright." Sara couldn't wait about what would happen next. The idea of having chakra which made her able to do special things made her curious and restless.

Sakura laid her hands softly on Sara's hands and concentrated by closing her eyes. A faint bluish light became visible from her hands. Apparently chakra had a blue color. For Sara it was weird seeing it in a visible form.

For her this was proof that it really existed. She waited for something to happen. But nothing did.

Sakura focused on the monitor and asked, "do you feel anything yet?"

"No, not really." Sara replied. The monitor didn't seem to show any differences either.

"I took only a little chakra so far, but I'll take some more."

Sara kept quiet, making sure she didn't break Sakura's concentration. Sara focust on the monitor instead. After a while she started to see a difference on the monitor. The chakra flow grew thinner. Sakura saw it as well.

"How does that feel?" She asked.

"I'm not feel any different to be honest."

After a while Sakura broke the chakra transfer by letting go off Sara's hands. "It seems like it had no effect on your vitals at all. Huh oh.." Sakura was surprisingly looking at the monitor.

The flow of chakra that grew very thin a moment ago was back to it's normal flow. "And your chakra's regeneration rate is very fast. It's completely back already."

Sakura added more notes to her chart. Sara wasn't sure what this all meant. But she figured that it was a good thing.

Sakura stood up when she finished her notes. "We are done here. Lady Tsunade awaits us at the hokage's office. We'll discuss the results there." Surprisingly Sara didn't see any of the shinobi guards when walking back to intelligence center. Apparently the hokages office was right next to it.

Sara followed Sakura through the long hallway of the hokage building towards the door that would lead to the office where Tsunade was waiting for them.

Sakura knocked on the door and immediately someone shouted. "Come in!"

Sakura greeted Tsunade by giving a small bow. She told her that she was done testing Sara. Sara however was distracted. She expected to see Tsunade in here, but she was not alone. Right next to her desk was also the silver haired Kakashi. Somehow it felt awkward for Sara to see him again. He just gave a little nod with his head as a greeting.

"Eh hello." Sara greeted them both and then looked down. Ashamed about the fact she felt this shy.

"Good." Tsunade replied to Sakura, "So? What are the results?" Tsunade seemed impatient.

Sakura read the summary of her chard. "Sara's body and vitals are normal in every way. She's healthy and fit. Only her chakra is something else, nothing like I've seen. She doesn't need any chakra to function normally. She has a very low chakra level, but if she runs out, she doesn't even notice. Next to that she has a very high regeneration rate."

"How fast?" Tsunade asked

"A second. Perhaps two, from zero to a hundred procent."

"That is fast. I mean it ain't much chakra, but it's still fast for someone with a low chakra level and considering she's not trained in using chakra." Tsunade concluded.

"Alright good work Sakura." Tsunade then turned around and stared out of the window. It was only for a few seconds, but the quiet in the room lasted so much longer for Sara. She felt tense about what will happen next.

Suddenly Tsunade turned around and spoke towards Sara. "Sara?"

Sara, startled from the sudden attention, straightened her back and answered. "Eh, Yes?"

"You are probably wondering what this is all bout." Tsunade already knowing Sara's answer continued. "We have no idea why you ended up in our world, but we do know a few things about traveling through other dimensions." For a brief moment she glanced to Kakashi when saying that. Like if he was the expert on this matter. "It's clear to me now that it wasn't you who could have done such a jutsu. It's takes immense chakra to make such a portal."

She walked a few passes through the room towards Sara. "We know it wasn't Kakashi either. No one we know off at this end of the world could have done such thing. It's already a very rare skill to teleport towards a travel dimension like we call it. But next to that, each jutsu user has it's own travel dimension. How you ended up into Kakashi's dimension is a mystery. We think it might have been someone in your world who made that portal that somehow corresponded with Kakashi's travel dimension.

"It must have been that criminal from my world." Sara concluded herself. Had there really been someone in her world that was capable of using these kind off powers?

"That would be my guess. Which would mean that this criminal is the only one being able to travel between your world and Kakashi's travel dimension."

"So you are saying I'm stuck in your world?" Sara asked, trying to figure out if there isn't a way out somehow.

It was Kakashi who broke his silence. His voice subtle, like if he wouldn't want to hurt Sara with his words.

"That criminal probably send you to my travel dimension in his panic when you cornered him. It was me who took you into our world. That criminal probably doesn't even know this world exists." Kakashi paused for a moment to make sure Sara could follow his thoughts.

Then he continued. "I never thought the travel dimension could be connected to another world somehow, but chances are that the criminal doesn't even know he send you into it. You could say you won a one on a trilion lottery running into me."

"So, my chances to get back to my own world are also close to zero?" Sara said disapointed. Realising what it meant she felt silent.

"Are you alright Sara?" Sakura asked after it had been silent for a while.

"I will be." Sara gave Sakura a little smile. "I just need a minute. It's a lot to take in."

It was Tsunade who took the conversation back to business. "We'll have to find you a place in our world. I think you'll best be suited a job as a shinobi. But with your chakra level and lack of experience that might not be an option. However seeing that you have such an exceptional high chakra regeneration rate, I want to give you a chance to proof yourself."

Sara wasn't really interested in what job she would get in this world. Her mind was with her brother, who will be worried about her. He would have no idea what happend to her. Probably thinking she was missing, searching for her right now. She could only hope he wouldn't try to hard.

Her few friends will forget her over time, they'll be fine. They probably only wonder why she wouldn't reply to their messages and be angry about it. Her cat would go to an animal shelter. But he's a nice kitty, he'll find a new and nicer home in no time. Her colleagues, she wouldn't miss at all. Sara wondered if they would even feel guilty about the fact they couldn't keep up with her in the first place. She hoped not though. To be honest, she would miss her bank account the most. She had been saving all her life and now it was all for nothing. She wanted to use it to travel the world. It was probably going to her brother over time. At least that could make him a bit happier. He did like money.

"Sara?" Tsunade broke Sara's thought calling her name.

"Sorry what were you saying?" Sara put her memories away for a later time.

"I was saying that I've arranged a room for you to stay in our local inn. It'll be on our cost. You can stay there until you can find a place of your own. In return I want you to start training. I'll give you a chance to show me your skills as a shinobi. Unless you rather require a different profession?"

"Do you have websites in this world?" Sara thought about all the things she was good at before working for the police.

"No."

"Photoshop is probably not a thing either?"

"Eh no.."

"Then yes, it's a good idea to try this shinobi thing..." Sara smiled. Then she added. "Thank you... It does mean a lot to me." Realising it would mean she was going to learn to use awesome powers and such. How could she deny herself such things? She should be more thankful for this opportunity. She was just a stranger for them after all.

"Very well. You'll get one day off tomorrow. After that you'll be training everyday. Make sure you will be ready the day after tomorrow at 7AM. Someone will get you at the inn lobby."

Sakura showed Sara were she could find the inn and made sure she got everything she needed. It was only a short walk from the Hokage's office.

Kakashi stayed behind with Tsunade. "Why do I have the feeling this training is going to involve me?" Kakashi asked.

"We'll have to find a way to trigger that girls chakra somehow and it won't be easy. Kakashi I'm counting on you, figure something out. She's got one week. Use tomorrow to find out what triggers her." Tsunade ordered.

"I thought tomorrow was her day off?" Kakashi asked hoping for a day off himself.

"She thinks it is. Use it to your advantages. You know I don't just give away free days. I'm paying for her stay after all. I could have been gambling with that money tonight."

"Technically this is a gamble. Like all other gambles of yours it's likely to turn into disappointment." Kakashi pointed out. He had been curious about this new woman. But even he had to admit her low chakra would be a problem. Besides how was he going to trigger her chakra if she never used it before? And even if he succeeded, what good jutsu could she use that would only use so little chakra?

Tsunade replied with confident. "I only lose when plain money is involved. I have a good feeling about this. She must be here for some reason."
