Shortly after the group met Naruto, they all entered the mansion, as they were also curious about the ninja and his abilities. Though, of course, Naruto asked for some food first, as he didn't know if he could explain things with how hungry he was.

Asami gladly ordered the servants to prepare some food.

A few minutes later, Naruto had scarfed down all the food.

"Ah. Thank you for the food. I'm satisfied." said Naruto patting his stomach.

"Well, okay, you've eaten. Can you tell us now who you are?" asked Mako.

"And how did you do that mind-blowing technique earlier?" asked Bolin secretly hoping he could learn that technique.

"Are you really from another world?" asked Korra remembering what the ninja mentioned earlier.

"Well yes. I would understand if you didn't believe it." said Naruto knowing that normal people would think such a thing was impossible.

"After seeing what you're capable of, I think you're telling the truth." said Asami.

"Why, thank you, uh…" started Naruto.

"Asami Sato and this is Mako, his brother Bolin, master Tenzin and his children, Jinora, Ikki and Meelo." said Asami introducing the others.

"A pleasure." said Naruto.

"If you're from another world, what's it like?" asked Jinora curiously.

"Well, for starters, regarding what I am, I'm a ninja." said Naruto.

"A ninja?" asked Korra.

"Are there no ninjas in this world?" asked Naruto.

"That's the first I've heard of that." said Korra with a shrug.

"Well, long story short, ninja are warriors trained to perform various missions in a hidden and stealthy manner." said Naruto giving his best explanation.

"So, are you like mercenaries?" asked Mako.

"No. Mercenaries take money from anyone, but we ninja in my world act more like an organization." said Naruto.

"An organization?" asked Asami.

"Yes. You see, in my world there are Five Great Shinobi Countries. The Fire Country, the Wind Country, the Water Country, the Earth Country and the Lightning Country." said Naruto.

"Sounds like the four nations of our world." said Tenzin.

"Four nations?" asked Naruto.

"In our world there are four nations. The Air Nomads, the Water Tribes, the Earth Kingdom, and the Fire Nation." said Korra.

"Wow, that sure is a coincidence." said Naruto.

"Yes, a big one." said Korra agreeing.

"Anyway, back to the story, in every country there are many ninja villages, but there are only five that are the strongest and biggest in the world. I come from the Fire Country, the Hidden Leaf Village." said Naruto.

"Now that you mention it, that band symbol on your forehead looks like a leaf." said Mako pointing to the ninja's band.

"That's right. Everyone who graduate from the academy receive one as a sign that they are ready to be ninja and accomplish missions." said Naruto holding up his sash.

"What kind of missions?" asked Meelo.

"They usually vary from rank. There are low rank missions like helping find lost pets or helping with clean up; then there are bodyguard or escort missions and lastly there are the assassination missions." said Naruto.

"Assassination? You mean they train you to kill?" asked Korra surprised by that information.

"Yes, ninja are basically tools for killing. We've been taught to kill since we started at the academy as children. In fact, when I was 12, I was in situations where any normal person would have died." said Naruto as if it was no big deal.

The listeners were quite surprised. On the one hand, they were surprised to learn that villages trained children to make them ruthless killers, and on the other hand, they were also surprised that the ninja in front of them had been in deadly situations.

"Bah. Don't worry. Just because I've been taught to kill, doesn't mean I like doing it. I only do it as a last resort." said Naruto hoping to calm things down.

"Still, you being trained to kill people since you were children is very cruel." said Asami.

"Well, that's the way ninja rules are. It's not something that can be changed that easily." said Naruto.

"Changing the subject. At that ninja academy do they teach you mind-blowing stuff?" asked Bolin.

"Yeah, like that thing you did before creating a copy of you. How did you do that?" asked Ikki.

"Oh, that was a chakra thing." said Naruto.

"You ninja can use chakra to do those techniques?" asked Tenzin in surprise, since, until now, chakra was nothing more than energy nexus.

"You don't use it to do those bending techniques?" asked Naruto.

"No, the benders have a special chi that allows us to manipulate the elements." said Jinora.

"How do you use chakra?" asked Korra curiously.

"Well..." started Naruto trying to think of the best way to explain about that topic, since theory wasn't his thing. "Chakra is an energy that flows through our body. We ninja use hand seals to manipulate the chakra inside us to use it in various ways, like walking on walls or through water."

"Really? That's amazing!" said Meelo.

"But one of the most basic things about chakra is elemental transformation." said Naruto.

"Elemental transformation?" asked Tenzin.

"Chakra has 5 basic natures. Air, water, earth, fire and lightning." said Naruto.

"Wait, you mean ninja can also manipulate the elements like benders?" asked Mako surprised, as were the others, at that.

"Yes and no. As I understand it, no one except the Avatar can manipulate more than one element, while there are ninja who can use jutsus of one element, there are those who can use jutsus of two elements or more, or even all elements. In fact, there is a ninja in my village who is able to use wood jutsus by combining water and earth jutsus." said Naruto.

All the listeners were amazed, as that meant that any ninja could be the Avatar by manipulating various elements. In fact, they realized the Five Great Shinobi Countries of Naruto's world were based just like his four nations.

"And you? What elements can you use?" asked Asami.

"Well, my chakra only has an air nature." said Naruto.

"Now that you mention it, I remember you did that technique during the fight against those men. Was it an air jutsu?" asked Korra.

"No, it isn't." said Naruto.

"Wait, what technique are you talking about?" asked Tenzin.

To answer that, Naruto created a clone next to him and showed him his open palm. The clone began to make tearing motions over the palm, causing a sphere of blue energy to form, much to the surprise of those present.

"This is called Rasengan, it's a technique created by my father that consists of accumulating chakra and rotating it in such a way that it forms a small tornado." said Naruto showing the technique before making it disappear by clenching his fist.

"Well in my opinion, it looks like an airbending technique." said Jinora.

"Yeah, and it's mind-blowing." said Ikki imagining for a moment doing something like that.

"Are there more techniques like that?" asked Korra.

"Well, yes. First there are the genjutsus, which are illusionary techniques that can fool the enemy; then there are the summoning jutsus, in which the ninja can summon various things from a distance; then there are the taijutsus, which are basically physical techniques; and lastly there are the hidden jutsus." said Naruto.

"Hidden jutsus?" asked Mako.

"They are jutsus that are exclusive to certain ninja clans. For example, my friend Shikamaru, who belongs to the Nara clan, possesses the shadow possession jutsu, which allow them to use their shadows to trap the enemy or Shino, from the Aburame clan, who can use insects as weapons." explained Naruto.

The listeners were more and more surprised. At first, they thought that ninjas were like benders, but now, after learning that they could also create illusions, summon things, use shadows and even insects, it made them see ninjas as powerful warriors.

In fact, if a bender and a ninja were pitted against each other, most likely, the ninja would win.

But Korra was also focused on something else. Despite knowing where Naruto's abilities came from or the various techniques the ninja had, he hadn't mentioned anything about the energy that dwelt within him. That topic was most likely personal, so she decided to leave it for another time when it was just the two of them.

"Wow. You ninjas are mind-blowing." said Bolin.

"Haha. Thanks." said Naruto with a smug grin.

"Come to think of it, why are you here?" asked Mako.

"Well, it all started when old Tsunade asked me to do a mission." said Naruto.

"Old Tsunade?" asked Asami with a raised eyebrow.

"She's the Hokage of the Hidden Leaf Village." said Naruto.

"Hokage?" asked Korra.

"He is the person who is in charge of the village. He is the one who organizes the missions and the squads. Each village has its own Kage and they are all considered the strongest ninja in the world. In fact, I aspire to be the next Hokage." said Naruto smiling and pointing his thumb at himself.

Everyone was slightly surprised, as they weren't able to imagine what kind of power the Kages had to be so powerful, but they were also impressed that Naruto aspired to be one.

"Anyway, she asked me to sort through the files. While doing so, I found an ancient scroll that, for some reason, led me to this world." said Naruto.

"You forgot to comment to them that that reason was that you were too curious and touched what you shouldn't have." said Kurama.

"That goes without saying." thought Naruto.

"So, you have no way to return to your world?" asked Jinora.

"No, but I'm not worried. I'm sure they'll notice my disappearance and look for me. It's only a matter of time before they find me in this world." said Naruto with a confident smile.

Korra couldn't help but let out a small smile seeing how much the ninja trusted his friends.

"I have an idea, why don't you stay here in the meantime?" asked Asami.

"Are you sure? I wouldn't want to be a bother." Naruto said.

"Not at all. Consider it a thank you for saving us earlier." said Korra agreeing with her girlfriend's idea.

Naruto thought about it for a moment. For a long time, he had learned to sleep in the open, so it might be an option in a world where his money wouldn't be worth it. So he saw nothing wrong with sleeping in a normal house, if you could call a huge mansion that.

"Okay, fine." said Naruto accepting the offer, making the two women smile at that.

After that, Tenzin left with his children to his home on Air Temple Island while Mako went to report to Chief Beifong, due to working for the police, everything he had learned from the ninja while Bolin went back home.

Asami offered Naruto a guest room where, as soon as he entered, the first thing he did was lay down on the bed.

"Well, that could be called a day." said Kurama.

"I tell you. Arriving on a new world, saving the Avatar and her friend from mysterious assailants. That's something one doesn't do every day." thought Naruto.

"Looks like your wish for some action has come true." said Kurama.

"Honestly, when I asked for that, I wasn't expecting any of this, but I guess it can be interesting, right?" asked Naruto.

"Still, don't let your guard down. That attack just goes to show that this world has its own conflicts too." said Kurama.

"I know. I know." thought Naruto starting to feel tired. "I wonder what they're doing in our world. Have they noticed I'm gone by now?" wondered Naruto before closing his eyes to sleep.
