"Assassin... and Space Ninja."

"Yep, she's a Space Assassin, and I'm an Interdimensional Space Ninja." Naruto answered as he slurped up the most delicious noodles he had in over 6 months, the ONLY noodles he has had in that amount of time, and it was far too long. "... and you are a beautiful, lovely, woman." Naruto pointed to the young girl who had made this delicious meal for him.

"Ah, thank you." Mikan stated, flattered at his seemingly genuine compliment.

"She's just the best, and her cooking is amazing. I love eating Earth food, it's so delicious." Lala absolutely agreed with Naruto's assessment of Mikan and her cooking. Yami was silently eating next to Naruto, while Rito kept a silent eye on both her and Naruto, since he didn't feel comfortable around either of them yet. "You being from a different dimension sounds awesome, you should tell me way more about it. Do you have any interesting animals and plants, I want to tell my little sisters all about your home dimension next time I see them." Lala wanted to ask Naruto so many questions about where he came from.

Especially the science.

"Your sisters like animals and plants huh... would you rather hear stories about the deadly Mountain Leeches, or the rare-"

"Both."

"Sure, I'm always happy to share stories about my home, so long as this little beauty keeps giving me ramen." Naruto laughed as he grabbed Mikan's shoulder and shook her body back and forth. Any woman that could make delicious ramen was a beauty in his eyes, and she made some very tasty ramen worthy of Ichiraku. "... and Rito, I'm sure Yami is sorry about scaring you with the entire assassination thing, I'll make sure she doesn't kill you." Naruto promised the boy.

"If he dies, no ramen from me."

"See, your sister knows the drill already. I'm not about to go killing the people who feed me, and I'm not about to let her do it either." Naruto was punched in the face by a hand made of hair when he grabbed the top of Yami's head, and unlike the elbow to the dick, it had no effect on him. He had been punched way harder before, so he could easily laugh off the love taps he was feeling from Yami.

Yami glared at him for not being affected by her punch.

So she decided to strike low, and she smirked a little smirk when he curled up under the table when she punched him in the dick.

Her eyes crossed moments later.

Naruto gave her a quick jap to the vagina from under the table, and within those moments both of them were curled up under the table holding their hands between their legs.

"You... punched my private parts." Yami muttered winded.

"Heheh, Pussy Punch."

-Days Later-

"Going to the Rito's school library again?" Naruto asked when he saw Yami walking out of the spaceship by herself once more. She really enjoyed learning about Earth culture, while he spent his time visiting the Yuuki house for food, and then going around the planet to see if he could find any cool stuff on this planet that didn't exist on his own home world.

"Yes."

"Cool, don't kill Rito today, Mikan is making me ramen again tonight." Naruto reminded her as he jumped out of the spaceship, and just fell towards the ground. He landed on his feet from a 300 foot drop, and started to just walk it off. Yami joined him after flying down moments later. "Also, Lala is going to call her sister Momo and introduce me to her. Apparently we have a lot in common, and Lala thinks we would hit it off." Naruto waved a 'see ya later' to Yami.

"Any books you want me to find for you?" Yami asked.

"Nope."

They parted ways with that.

-That Night-

"Wow, your life sounds pretty amazing! I wish I could have done even half of that stuff!"

"You have a very, very, smart sister." Naruto stated as he turned to face Lala, who was working on some kind of strange science thing that he couldn't make heads or tails of. Anyone who could understand how awesome he was had to be a pretty smart person.

"Yeah, she's a smart cookie!"

"Oh... yeah... I guess I am." Momo was blushing through the screen. "... and, you travelled through space and time... have you encountered any interesting plants in this universe I might not know about?" Momo asked him, curious since she was always looking to add more fun plants to her collection. If he travelled freely across the universe with an assassin, then he had to have some kind of knowledge.

Naruto nodded his head.

"Yeah, when I visited a club on an asteroid, there were these awesome 4th Dimensional Roses that were used to feed larva, which made the people who ate the larva stop aging. The flowers looked were located not just in this dimension, but on multiple different planes of existence at the same time. They were awesome." Naruto just dropped a thing that managed to stay with him from his 23 years partying at the club, something that hadn't been blurred out.

"... 4th Dimensional Roses?"

"Yeah, they exist outside of the 3rd Dimension, and regular people can't even see them. I can sense things and get visions of them, so I'm able to see things from that dimension pretty easily. The best way I can describe those flowers are... infinite and nothing at the same time. It was like there were infinite flowers stacked on top of each other, but no flowers at all." Naruto could see that he had caught her great interest as he explained the flowers, and Lala stopped tinkering with what she was working on to listen to him explain things about the 4th dimension and the roses that came from it.

Lala tilted her head.

"You can see things that exist on other planes of existence... that sounds awesome!" Lala shouted when it dawned on her that she could now use his knowledge to experience other planes of existence. Now she wanted to build a machine that would let her swap minds with Naruto, so that she could get a firsthand experience for what higher planes of existence were like. It would be extremely educational for her and help her reach new heights in her machine making hobby.

"I want to hear more about the 4th Dimensional Roses and the bugs that eat them! You can talk about other planes of existence later Lala!" Momo shouted at Lala through the screen, before she put on a very sweet smile. "... and... what other interesting plants have you come across, maybe some 5th Dimensional Lilacs?"

"Don't be silly, the 4th Dimensional Roses are just something that exist to be fed to special larva that can eat them. That club was filled with lots of awesome stuff that I can't remember well, but the stuff I kind of remember was awesome. They even had a room where a bunch of science nerds got together to research stuff for fun." Naruto described the party.

He had Lala VERY interested now.

"How much does it cost to get in?" Lala questioned him.

Naruto held up a hand and showed a Zero.

"It's all free, but you won't remember anything you experience the first time you go. Yami can't remember anything she did in the 23 years we were in that party. I can only remember about... well at first I could only remember like half, but now it's getting blurry, so I remember about a 10th of it." Naruto admitted that as time went on, his memories of the place other than select things that interested him had pretty much gone blank, and with each day he lost more of the memories. He made sure to remember the really important stuff though.

"I wanna go! You should take me Naru-chan!" Lala jumped on him.

"I wanna go too, I'll get Nana and we'll head to Earth as soon as we can sneak away from our tutor! I wanna get one of those roses, and I wanna hear more stories about the stuff from your world, like the cannon that blew up the moon you were..." Momo stopped what she was saying.

Something just clicked with her.

It clicked with Lala too.

"Wait... your planet didn't develop space travel, so how could you survive in space... and how did you survive floating in space for 5 months before Yami-chan got to you?" Lala just realized that didn't add up. Naruto clearly had a humanoid body, meaning that he had basic needs. She watched as Naruto turned to face her, and he started to unravel the bandages on his arm.

It looked like an arm.

His arm was the same color as the rest of his arm, but she looked and saw a line was connected to the middle of his arm. She watched as Naruto TOOK OFF his right arm and tossed it to her, and she realized that his entire right arm wasn't real.

Still, when she caught it, it was soft.

"Wow! This feels like skin, and muscle, and... how did you do this?"

"I lost half of my right arm in war, so my friends made me that one out of cells from a special guy. They grafted the cells onto my arm so the arm could connect better." Naruto showed a small surgery scar at the end of his arm where it ended in a flat stump, a perfectly flat part of his arm. "If you have these cells, you don't have to eat or drink, so you can survive without starving to death or dying of thirst. Also, that arm is special because while I can remove it, while it's attached to me-" Naruto grabbed his arm back from Lala.

He placed it back where it belonged.

She watched as the Naruto let go, but the arm stayed firmly in place as if it was connected to him like a real arm was. Naruto slammed his arm against a wall a few times, and it still stayed in place. It really was like the fake arm was part of his body. Naruto started to wrap the bandages up around his arm again, since he didn't really enjoy not having his bandages on even when he was casual.

"Wait, wait... so your people can graft new limbs onto people with such high accuracy and it can stay on, but you can't travel the stars... that doesn't make sense at all. How can such a highly advances society-"

"War."

...

"The answer is war, my people were warmongers who didn't calm their asses down until the last war we had. All of our technology went towards protecting ourselves against threats from the stars. We had no reason to want to travel a universe where he never thought other life was worth finding. Still... pretty cool arm right?" Naruto asked with a grin.

"Can I study your arm... I want to try and make a cool arm like it!" Lala asked as she grabbed his arm and held it close to her body.

While it was still attached to him.

"You... want to borrow my arm?" Naruto asked her.

His turn to be confused.

"I want to see if I can make an even better arm, this arm is really cool, but I know I could make an even better arm if I really tried. I could add lasers, and a cannon, and a vacuum suction function, and a massage function." Lala felt him pull his arm out of her grasp.

That was her answer.

"Sure." Naruto popped his arm off and handed it to her.

"You don't have to give your arm to her." Momo pointed out.

"I'm not giving it to her, I'm letting her borrow it for a few days. I went years with only one arm, I can go a few days without it." Naruto could see her genuine desire to make a new arm for him. Naruto turned back to Momo. "Also, don't sneak away from your tutor just to come see me. I was a horrible student growing up, and it became a pain in the ass to fix-" Naruto started, but Momo was grinning as she hung up.

"Yeah, she and Nana sneak out of their lessons a lot to sneak off and find new stuff." Lala stated.

Teenagers would be teenagers.
