A day had passed since Naruto arrived in the city of Rimuru.
Now that he knew he could return to his world in a matter of days, he felt more relaxed and decided to take advantage of his time in that city to explore a bit and learn more things about that world.
As he walked through the streets of the city, he couldn't help but compare it to his home, with the only difference being that there were no humans and no ninjas either, but if Souei's power was of the caliber he showed during their fight, then he could tell that there were surely more people equally powerful or even more.
"If that nation was in my world, surely, it would have become the sixth nation." thought Naruto.
"I think so too. The power emitted by both Lord Rimuru and some other people here is very great. I'm beginning to think that, if another war were to happen, it would be this nation that would be declared victorious." said Kurama.
"I think so too. Although I wonder what Rimuru is really capable of. If he's on the same level as a bijuu, then he'll have a whole arsenal of abilities." thought Naruto.
"All the more reason not to fluster him. At best, he could lock you up and at worst, kill you with the worst of deaths." said Kurama.
"Oh, come on. When have I ever pissed anyone off?" asked Naruto.
"Do you really want me to answer that question?" asked Kurama with a bead of sweat, causing Naruto to chuckle slightly.
It was then that Naruto noticed something out of the corner of his eye and turned his head to see a certain girl with horns.
"Ah, Shuna." said Naruto catching the young kijin's attention.
"Oh, hello there, Naruto. I've already heard that you are now a guest of the city. I'm glad for that." said Shuna.
"Thank you. The truth is, it wouldn't have happened if you hadn't helped me when I arrived. So, if you need help, you can count on me." said Naruto pointing a thumb at himself.
"Really? Thank you very much. Now that you mention it, I could use your help for one thing." said Shuna.
"What is it?" asked Naruto.
"Follow me and I'll tell you." said Shuna.
Shuna led Naruto to a store and upon entering, the jinchuriki saw various outfits ranging from kimonos to normal or combat attire.
"Well, here we are." said Shuna.
"Why are we in this store?" asked Naruto.
"Oh, I'm sorry if I didn't tell you, but I'm in charge of most of the garments in town." said Shuna.
"Huh? You made all this?" asked Naruto.
"Well, not all of it. I had some friends help me, but most of the designs are usually my own doing." said Shuna.
"Wow. You certainly have a lot of talent." said Naruto with a smile.
"T-Thank you." said Shuna slightly blushing.
That's when she noticed a playboy bunny outfit on a mannequin on the side of the store.
"Hey, Shuna, who is this outfit for?" asked Naruto.
"Well, for Lord Rimuru." said Shuna.
"For Rimuru?" asked Naruto completely confused.
"Yes, we usually make him dresses and suits for him to try on. It's so cute to see him dressed like that. In fact, we have many models for him to wear." said Shuna pointing to a section that included maid costumes, sailor costumes, even a magical girl's costume.
Naruto was completely taken aback by the revelation before puffing out his cheeks in an attempt to contain his laughter.
Though that wasn't the case for Kurama, who was rolling on the floor as he burst out laughing.
"HAHAHAHA. Rimuru, the leader of a powerful nation, a being who is as strong as a bijuu, treated like a doll! HAHAHAHA." said Kurama laughing out loud.
"H-Hey, Shuna, would you mind letting me know when you are going to dress Rimuru. I'd like to see it." said Naruto trying to hold back his laughter.
"Sure. We could use an outside opinion." said Shuna with a grin.
"Oh, man. I'm going to burn that memory into my mind for years." thought Naruto with a mischievous grin. "Anyway, what do you want me to help you with?"
"You see, I was thinking of a fashion line based on Souei and his squadron members. I was thinking of asking them for it, but you showed up earlier, so I thought you could help me out a bit." said Shuna.
"Sure. No problem at all. I know a few things about ninja fashion. I hope I can be of service to you." said Naruto.
"That will be more than enough." said Shuna.
For a while, Naruto was giving Shuna ideas about ninja clothing designs and even agreed to let her take his measurements.
He also met Shuna's designer friends which consisted of a trio of dwarves.
There was a moment when the three of them started talking about a new design for Rimuru and Naruto couldn't help but give little opinions to make the design better (and more embarrassing).
Later, Naruto was walking around the city until then, he ended up in some kind of training camp.
There he saw an older man with horns with several people with green skin and gray hair.
All of them carrying wooden swords.
The hobgoblins lunged at the older kijin with all their might, but then…
In less than a second, the older kijin was in another part of the field and a second later, the hobgoblins fell to the ground unconscious.
"Unbelievable. It went so fast I didn't even see it." said Naruto in surprise.
That's when another hobgoblin, a big-headed one with a big nose walked stealthily behind the older kijin with a wooden sword.
When he was close enough, he leapt towards him with sword raised high, ready to attack him while he was oblivious to him.
Or so it seemed, for in another swift move, the older kijin struck the hobgoblin and sent him crawling across the ground to stop at Naruto's feet.
"Hey, buddy, you okay?" asked Naruto.
"Easy. They usually tell me I have a lot of stamina." said Gobta.
"By the way, who's that over there?" asked Naruto.
"What? You don't know master Hakuro?" asked Gobta standing up abruptly.
"Well, I've only been here for a day and I don't know everyone." said Naruto rubbing the back of his head.
"Oh, well, that's understandable. Anyway, it's about master Hakuro. He's a great swordsman, having trained Benimaru, the commander-in-chief and Lord Rimuru himself." said Gobta.
"Wow. He's certainly a great warrior if he trained them." said Naruto.
"Thank you, young man. I'm just doing what I have to do." said Hakuro approaching them.
"Still, you have good moves for an old man." said Naruto with a smile.
That made Gobta's expression of horror as Hakuro's eyes glowed red.
A second later, Naruto's cries of pain could be heard even from a distance.
Soon after, Naruto was on a bench with bandages on his face and a pained expression as he held his side.
"Hehe. I should have told you that the master doesn't like to be called that, right?" asked Gobta with a nervous smile.
"Yes! You could have told me!" exclaimed Naruto angrily before holding his side in pain. "Ow, ow, ow. Oh my god. That guy's punches make old Tsunade's butterfly slaps."
"Old Tsunade?" asked Gobta curiously.
"She's the leader of my household. She may look like a young woman under 30, but she actually uses a technique that makes her look younger no matter if she's 50-something." said Naruto.
"Ay, it's a pity. There's nothing more pathetic than a woman trying to hide her age through trickery. She's crazy if she thinks people will keep seeing her young like that." said Gobta.
Back in the Hidden Leaf Village, in the Hokage's office, Shizune, Tsunade's attendant and assistant was reviewing some documents when suddenly she felt something behind her and turned around, only to be completely terrified when she saw Tsunade with a large black aura surrounding her and a look of pure death.
"L-Lady Tsunade, w-what's wrong with you?" asked Shizune.
"I feel like someone has insulted me in the worst way and when I catch him, I will kill him." said Tsunade.
"My god, whoever pissed her off like that, I pray for his soul." thought Shizune in fear.
"Hahaha. I think so too." said Naruto.
"Of course, the only women who manage to stay forever young despite age are elves." said Gobta.
"Are there elves in this world?" asked Naruto.
"And so there are! In the Armed Nation of Dwargon there is a bar where the hostesses are gorgeous elves! Just thinking about them makes me feel like I'm in paradise!" exclaimed Gobta excitedly as an image of the elves in the bar appeared in the sky.
"Hehe. That would certainly be a great place for the perverted hermit to go to often." said Naruto imagining Jiraiya looking at the elves with a perverted grin.
"Who?" asked Gobta.
"He was a teacher of mine. He was a very strong one, but he was also a pervert. He was always peeping into the girls' bathrooms to 'gather information' for his perverted novels." said Naruto with a grin.
He may have been a pervert, but deep down, he was like a grandfather to him.
"Really?" asked Gobta before leaning closer to Naruto with one side of his mouth covered with the back of his hand. "Hey, and you wouldn't happen to have one of those novels handy by any chance?" asked Gobta quietly.
"Well… No, but I know someone who has a bunch. If the opportunity arises, I'll give you a copy." said Naruto.
"Perfect." said Gobta with a thumbs up and a wink.
Later in the day, Naruto went to an area of the forest surrounding the city, where he was to meet Souei and his squad.
When he arrived at the meeting point, he saw no one.
"Huh? Wasn't I supposed to meet the others here?" asked Naruto looking around.
That's when he felt something incoming and jumped back in time to avoid some kunais that dug into the ground.
Using chakra control, Naruto landed on his feet on a tree trunk.
"Hey! What was that for?" asked Naruto in annoyance before a girl in a red colored ninja outfit landed on the ground.
"My apologies. Master Souei alerted me to your arrival and wanted to check your skills personally." said the girl.
"What a mania everyone has for testing my skills." muttered Naruto under his breath. "And who are you?"
"My name is Souka, second in command of the Shadow Squad." said the girl introducing herself.
"Ah, I see. I am Naruto Uzumaki." said Naruto introducing himself.
"Hey, how come you're standing on that tree like nothing? Is it some kind of spell?" asked Souka curiously.
"No." began Naruto before lowering himself to the ground. "You see, where I come from, we use chakra and by applying it to our feet, we can walk on various surfaces, including water."
"Really? Interesting. It would be very useful for us to have a technique like that. Do you think we could learn it?" asked Souka curiously.
"Well, I'm not sure if it will work on someone who has magic, but we could try it." said Naruto.
"What other techniques do you know of that can help us on missions?" asked Souka.
"Well, the most basic technique if it comes to spying and gathering information is camouflage, but I developed a technique of my own that allowed me to escape from any situation, I even took down a couple of people with it." said Naruto.
"What kind of technique is it?" asked Souka curiously.
"Prepare to be amazed." began Naruto before he waved his hands, causing an explosion of smoke to cover him and when it dissipated, it was revealed to Naruto that he had transformed into a girl and was completely naked. "Sexy Jutsu!" shouted Naruto as he struck a very erotic pose.
"Oh, right. That way, men are easily distracted and tell you everything." commented Souka.
The next instant, a hand smacked Naruto's head, causing him to undo his transformation.
"Ouch! Why did you do that?" asked Naruto to Souei, who was the one who hit him earlier.
"Don't teach her those dirty things." said Souei.
"Master Souei, does this look erotic to you?" asked Souka in an erotic position.
"Don't even think of imitating him." said Souei.
"Hey, she asked me for advice and that's what I was doing." said Naruto.
"Still, I won't tolerate those kinds of techniques in my squad. Although that water walking technique sounds interesting." said Souei.
"Well, like I said before, we can give it a try." said Naruto.
"Well, let's go meet up with the others." said Souei before he and the others disappeared.
For a couple of hours, Naruto was hanging out with the Shadow Squad, telling the others about some missions he did, as well as various techniques they could use.
They first tried using the technique of walking on surfaces and water, but at first, it didn't work.
However, Naruto suggested concentrating their magic on their feet in the same way he did with chakra and in that way, they succeeded, although they would need training to perfect it.
He also told them about the storage seals, which consisted of a seal that led to a mini pocket dimension where they kept many things.
Fortunately, it was easy to learn, since, with applying magic, the seal worked the same way as with chakra.
Souei mentioned that they could use those seals to carry multiple things with them without any problems.
Later in the day, Naruto was with Rimuru in a room having a small snack consisting of tea and sweets.
"So, how are you doing in the city?" asked Rimuru.
"Pretty good. Everyone is good people." said Naruto.
"As the founder and leader of this nation, I'm glad to hear that." said Rimuru with a smile.
It was then that Shion entered the room.
"Lord Rimuru, this letter has arrived for you." said Shion showing a letter.
"Oh yeah? Let me see." began Rimuru taking the letter and reading its contents, causing a big smile to form on his face. "Wow, what do you think?"
"What? What does the letter say?" asked Naruto curiously.
"It seems that my students wish to see me." said Rimuru revealing the contents of the letter.
"Your students?" asked Naruto with surprise and curiosity.
Omake
Rimuru, in his slime form, was in his little house, enjoying a moment of relaxation.
He was totally calm and sinking into peace until Shuna and Shion stood in front of him.
"Lord Rimuru, can you do us a favor?" asked Shuna.
"Sure. What is it?" asked Rimuru.
"We have a new outfit we'd like you to try on." said Shion.
"*Sigh* The usual routine. Well, the sooner I does it, the sooner it'll be done." thought Rimuru.
"Besides it's a special outfit." said Shuna.
"Special? In what way?" asked Rimuru.
"In that Naruto helped us design it." said Shuna with a smile.
"Ah, I see. In that case… Wait, Naruto?!" asked Rimuru totally surprised.
"Yes." began Naruto suddenly appearing with a mischievous grin. "We put a lot of effort into designing it and it would be a shame if you didn't try it on."
Rimuru had a feeling that he had done something mischievous with that outfit.
He wanted to refuse, but seeing Shion and Shuna's smiles and glowing faces, he knew he couldn't, as it would make them very sad and possibly angry.
"I-It's okay. I'll try it." said Rimuru. "I hope it's as bad as I think it is."
LITTLE LATER
"I was right! It's much worse than I thought!" thought Rimuru who was now wearing a succubus costume that left a lot of skin exposed, covering the breast part in the process, and came with demon wings, horns and tail, as well as stockings, heels and a short foul.
"How cute! It suits you perfect with you Demon Lord title!" said Shion with a smile.
"What do you think, Naruto?" asked Shuna.
The jinchuriki was leaning with his hands and knees on the ground, doing his best not to burst out laughing.
With all his might, he lifted his head to give the pink-haired kijin a toothy grin and a thumbs up.
"Y-You look perfect in it, no doubt." said Naruto.
Inside Naruto, Kurama was laughing nonstop, holding his stomach so he wouldn't break.
Rimuru growled in frustration as he watched the ninja, and, most likely, the bijuu, laugh at his expense.
"Damn you, Naruto. I'll make you pay for this. Boy will I make you pay." thought Rimuru angrily.
