As much as I would like to simply start with the story, I need to explain the setting first since I don't want to begin when Shin moves to Konoha. That's 'Legendary Ninja Shin-chan 0'.

I use the FUNimation cast because I'm more familiar with them. Only Shin-chan, Masao, Bo (all 12) and Himawari (8) go to academy. Honestly, I just don't want to create too many new teams. Bo is quiet but not retarded here, Masao still easily scared and you will read about Shin often enough.

After becoming close friends with Shin-chan, Naruto lives with the Noharas. He got secretly adopted by them but he still goes by his original name.

Shin-chan is as infamous as Naruto in the village but both have friends and are generally happy. I won't say anything about the relationships with the other classmates, only that some big incidents happened.

Also, in Shin's favorite TV show Action Bastard is a really strong ninja.

Legendary Ninja Shin-chan: Shake in laughter before him

Chapter 1: You are the Nine-tails?!

Naruto sat on a swing, depressed by his failure. He watched all the happy graduates who were praised by their smiling parents. If he had passed, the Noharas would have done that with me, too. He sighed deeply. Looking around, he spotted Misae, Hiro and Himawari but Shinnosuke wasn't with them.

"Shin-chan! Where are you?" They shouted several times. However, Shinnosuke didn't come. "I wonder where he is. I doubt he already went home."

"Maybe I should search, too." A quiet voice said behind Naruto.

Naruto sighed and muttered to himself. "Yeah. It's better than moping around." He continued a bit louder. "Shin."

"HERE!"

Naruto jumped up, surprised by the sudden shout from behind. He tried to turn around at the same time but with the swing between his legs, Naruto lost his balance and fell on his back. He looked up at Shinnosuke who laughed at him.

"Shin, why aren't you over there?!"

"It looked like you were having fun." He told Naruto with a straight face.

"How can you get the idea that I was having fun?! I failed! I want to be alone!"

"Oh." For a few seconds, there was silence. "How about now? Wanna play ninja?"

"NO! Aaargh, .." Naruto stood up and ran past him.

"We can play hide and seek, too."

Misae, Hiro and Hima came over to Shinnosuke.

"Was that Naruto?" Misae asked.

"Yeah, Mitzi. We are playing hide and seek. By the way, I think he has his special days."

"Only women get these days, Shin-chan. What happened to Naruto?"

Shinnosuke shrugged. "Not much. He only failed again."

"Poor Naruto-niichan."

Shinnosuke was still searching for Naruto, even though his family told him that Naruto should be left alone for a while. Oh, and that Naruto WASN'T playing hide and seek with him. But that was stupid. Playing hide and seek was far more fun than feeling sorry for yourself after all.

Suddenly, Shinnosuke heard Naruto's shout. "Hey, Shin." He was obviously far happier than before.

"Found you! Now, you have to find me!"

"Huh? It doesn't matter." Naruto continued happily. "Mizuki-sensei gave me another chance. The only thing I need to do is to steal some scroll and learn one technique from it."

"So you don't want to play anymore? Then you have to say the magical words!" Shinnosuke got closer and whispered into Naruto's ears. "It's 'Please release me, master.'"

"What?! I will never say something like that! And stop reading those orange books of dad!"

"Ah, well." Shinnosuke shrugged. "Can I join you?"

"No. He said that I have to do this on my own."

"What if I only followed you and you did everything on your own?"

Naruto pondered a bit. "Okay, but be quiet."

"I'll be as quiet as a mouth."

"You mean a mouse."

After having knocked out the Hokage with his Sexy no Jutsu, Naruto was searching for the forbidden scroll Mizuki mentioned.

Meanwhile, Shinnosuke was searching for interesting stuff at Hiruzen Sarutobi's home. He moved to Hiruzen's study. He sat down on the revolving chair behind the desk. "Comfy." He spun around a few times, yelling 'Woohoo'. However, he became dizzy soon. In this state, he got up and tried to walk away. When he lost his balance, Shin tried to grab the edge of the desk. Instead though his hand reached to the big stack of paper.

Shinnosuke gulped at the mess he made.

"Shin! I've found the scroll. Let's go!"

"Uh, one moment!" "I have to think fast. Ah, that's it." Shinnosuke giggled to himself. He wrote a small note and left.

"Nothing happened, hahaha!"

"Okaaay. Then why are you telling me?"

"Just because."

A few hours later in the woods …

Shinnosuke was leaning against a tree, still exhausted from one attempt at the Shadow Clone technique. In contrast, Naruto was still going on without a break.

That's when they heard a scream from the distance.

"Was that the old man?" Naruto asked.

"He sounds like he woke up from a nightmare." Shinnosuke added.

"SASUKE UCHIHA!"

While Naruto was confused, Shinnosuke began giggling.

"You should hurry up, Naruto. The old man will come looking for you."

"You are right."

Shinnosuke stood up and walked to the tree a few meters in front of Naruto. He dropped his pants and underwear and began to pee. Naruto looked to the side with a twitching eye but he continued to practice the Shadow Clone technique without complaining. The next thing, however, he couldn't let pass.

"Go somewhere else!"

"Why?" Shinnosuke was squatting on the ground with his butt out.

"I don't want to see you doing it!"

"But -"

"NO! I don't want to see, hear, smell or anything else about your poo!"

Shinnosuke stood up and pulled up his pants and underwear. He turned his back towards Naruto. "Are you happy now, Naruto?"

Naruto rolled his eyes at his dramatic act. "It's more relief than happiness."

"Don't come looking for me." After saying these words, Shinnosuke ran off.

Naruto shook his head, but a few laughters still escaped his mouth. Finally, he resumed his training. "Just this one jutsu. Then I'm going to be a ninja."

After taking a dump, Shinnosuke looked around him. "Nothing but trees here. How do I get back to Naruto?"

Thirty minutes later, Shinnosuke had still not returned. Naruto began to feel worried about him. He managed to complete the Shadow Clone Jutsu in the time Shin was away and now he wanted to surprise him with it. He was leaning against a tree when someone appeared in front of him all of a sudden.

*****The following parts is only a slightly shortened version of the same part in the manga******

"I found you!"

"Are you going to test me instead of Mizuki-sensei, Iruka-sensei?"

"What kind of -"

Iruka had no time to complete his question as he had to intercept the kunais that flew towards Naruto. Injured by several kunais, he looked up at Mizuki who was standing on a tree.

"Naruto, give me the scroll!"

Confused, Naruto switched between looking at the calm Mizuki and bleeding Iruka. "Hey, what's going on?! Hey!"

"Naruto! Don't give him that scroll even if you die! That is a dangerous scroll that has forbidden ninjutsu sealed within it! Mizuki used you in order to get his hands on it!"

When Naruto tensed, Mizuki stared at him intently. "Naruto … there is no point in you having it. I'll tell you the truth."

"NO! DON'T!"

"12 years ago … you know about the demon fox being sealed right? After the attack, a new rule was created in the village. However, it was never meant to be told to you."

Naruto listened to each word with wide eyes.

***** new part here *****

Mizuki started to laugh to himself. He was going to enjoy the last moments of the demon and decided to draw this a bit out. "Can you guess what it is?"

"What … kind of rule is it?"

Mizuki could barely contain his laugher. "The rule is …"

"Oh, oh, I know the answer! I'll be the new candidate, Shinnosuke Nohara!" Suddenly, Shinnosuke appeared between Iruka and Naruto. The light dimmed except around Shinnosuke and Mizuki.

"Let's hear your answer then, Nohara-san!"

"It's something that Naruto mustn't be told about … and there is only one answer to that. If anyone told Naruto about the huge ramen sale in the Shirakawa mall on the third friday every month, he would only eat ramen since you get 100 packs for only 50 Ryo!."

"Wow, how cheap!"

In reaction, Iruka slapped his forehead.

"Unfortunately, that's the wrong answer. The rule is that nobody is allowed to talk about the fact that Naruto is the demon fox that -"

Shin cut him off. "Okay, next question."

"Right. What are the three magical numbers of Tsunade of the Sannin?"

"Hmm. Her bust is definitely over 100 -"

"WAIT! This isn't a quiz show! I'm about to kill Naruto!"

"Then, you really suck at this. You shouldn't play quiz show host in the middle of killing someone." Shinnosuke stated.

"That's your fault!" Mizuki yelled back. "Ugh, where was I?" He thought aloud.

"Oi, what happened to the evil fox demon?"

While Naruto's shock turned into depression, Mizuki resisted the urge to shout at Shinnosuke again. Since the question was related to what Mizuki was planning to say, he decided to answer it.

"Naruto is the demon fox that killed Iruka's parents and destroyed the village. It means …"

"STOP IT!" Iruka shouted.

"you were sealed up by the Hokage you admire …"

"STOP IT!"

"You have been lied to by everyone! - Didn't you find it odd how everyone hated you? Iruka is the same! He actually hates you!" Mizuki aimed his large shuriken at the shocked and depressed Naruto. "Nobody will ever accept you! That scroll was used to seal you up!" He threw ...

"Whaaaat!? -"

… and missed completely. "Dammit! Stop interrupting me already!"

Shinnosuke turned towards Naruto. "You are the Nine-tails!? But you …"

"You are realizing it just now!?" Was the thought, the two chunin shared.

Naruto looked at Shin with empty eyes. "Now, he will hate me too."

"… have only one tail and it's shorter than mine."

Naruto's eyebrows twitched. "It's no wonder if you pull on yours all the time."

Shin started to act shyly. "So … you are looking at me … I thought you loved Hinata. I -"

Naruto sputtered. "It's nothing like that! I swear!" He waved his hands in front of him. "I'm straight! And Hinata-chan is only a friend! Nothing else!"

"I love you, too, Naruto-niichan." Shinnosuke turned towards Mizuki again and glared at him. "No one's going to hurt my brother and get away with it! Except for mom when he is an idiot! But she usually punishes me for some reason!" Shinnosuke glanced over his shoulder at Naruto who joined him at his left side. "Let's kick his ass like Action Bastard!"

"Yeah! Let's kick his ass!" Naruto raised a fist in the air.

Mizuki wasn't sure what happened in the last few minutes but there was no turning back. It was three against one now.

"Good luck, Naruto. You are on your own." Shinnosuke took a few steps back.

… or maybe not.

"Come back! I thought we would beat him together!"

"This is your test, remember? I mustn't interview."

"Interfere. And he lied. So it's okay if we work together."

"You know … if you can beat a chunin on your own in a real fight, you must be good enough for genin."

"Shin ..." Naruto drawled.

Iruka had watched everything from the sideline. Honestly, he was prepared to protect Naruto with his life but somehow Shin's … Shinness, that was the only word he could think of to describe him, stopped Mizuki's attack. However, Shinnosuke wasn't simply a goofy child with the sex-drive of a hormon-crazed teenie if you looked past ... well ... actually … nearly everything. Yeah, he truly cared for Naruto but this -

"You can beat him, Naruto. When you do, you get Iruka's headband and he is going to treat us to ramen."

"Hey! I haven't agreed to anything!"

Naruto looked at Shinnosuke again and nodded.

"Pfff. Like one academy student can beat me, no less you." Mizuki sneered at Naruto. "I'm going to kill you!"

"BOOOOO!"

"Maybe not one, but maybe a thousand. Shadow Clone technique!"

Suddenly, Mizuki was surrounded by thousand Narutos. They rushed at the panicked Mizuki and beat him up.

"VICTORY DANCE!" Shin shouted. "GANGNAM STYLE!"

Naruto and his clones shrugged and started to dance along with Shin.

Iruka sweatdropped. "How could this ever become popular?"

Later at the Hokage Tower …

Shinnosuke, Naruto and Iruka returned the forbidden scroll to the Hokage. He told them that they acted correctly and gave them the payment of a B-ranked mission though Iruka gave his part to the other two.

Shinnosuke held his hand out to Naruto. "You, too."

"What?! I beat him while you watched me!"

Shinnosuke pouted. "You are really greedy, Naruto."

"That's what I should say about you."

The Hokage coughed to get their attention.

"Need a cough drop, old man." Shin asked.

"No. I have some good news and some bad news to tell you." The Hokage looked at Naruto. "First, congratulations Naruto, you pass and become a genin of Konohagakure."

"Really?" Naruto asked with tears forming in his eyes.

The Hokage nodded with a smile. "How could I not let the future Hokage pass."

Naruto glomped him while saying 'Thank you' over and over.

Iruka smiled and clapped.

Shin began to whistle. "And now kiss."

Immediately, Naruto separated from the Hokage with a red face.

Iruka punched Shin on the head. "It was nothing like that."

"But that's what happened in the last episode of 'The scret love of Matsumoto' when he came back from a mission and cheated on his wife with his sensei."

"It was his older teammate. How can you even watch this?"

"Dad taught me how to crack the codes of the child safety device when I was five. How do even know so much about this soap opera?"

Iruka swallowed. "…"

The Hokage cleared his throat.

"Are you sure you don't need a cough drop?"

The old man sighed. "I'm getting too old for this." "I don't. Shin-chan, you will clean up the mess you left in my study. I want you to sort all requests, formulas, draft bills and other things by type and urgency."

"But it was Sasuke. I've even left the note that said so after knocking the stack over."

While Naruto slapped his forehead and Iruka facepalmed, the Hokage gave him a flat stare.

"But the stack was huuuge." Shin whined.

"That's your problem."

"Okay, I'll deal with it like a man." He puffed his chest and sent the Hokage a defient look. "Naruto?"

"Oh no, you do it on your own." Naruto crossed his arms. No success with Iruka either.

At this moment, a man entered the room with a large stack of paper.

"Hey, you, are you good with paperwork?"

The man blinked at this question. "I'm the Hokage's personal assistant."

"How about some extra cash for doing my paperwork?" He waved his bundle of bills in front of him.

"Okay, I will -" Then, he noticed the Hokage's look. "Erm, I mean, I have many other things to do like …"

The Hokage interrupted him. "I'm sure you were very eager to help Shin-chan with his punishment." "Huh?" "So you can watch over him. Make sure he does everything correctly and answer his questions."

The assistant sent him a pleading look but bowed his head in the end. "Yes, Hokage-sama."

"I potty you."

"It's pity and it's still your punishment."

"That's what you think."

OMAKES

Omake: Alternate chapter 1

Mizuki stood on a protrusion of a house near the Hokage Tower as he watched Naruto run away with the forbidden scroll. He smirked. His plan went nicely. Actually Naruto got the scroll much faster than he expected him to. But that wasn't a bad thing. "It just means that I can move on with my plan much sooner. Heh heh heh, he has no idea that he has shortened his own life because I will get rid of him sooner. Nothing can stop me now. Bwahahahaha..."

"Hahahahaha..."

Then, Mizuki noticed the second laughter next to him. He stopped laughing and looked at the person who laughed along with him.

"So what's so funny?" Asked Shinnosuke.

"Oh I just thought of a funny joke, hahaha." Mizuki laughed. "Damn you kid!"

"Wow, tell me!"

"I can't tell you."

"Of course you can, this is already rated M. Oh, that was a random rap!"

"That's nice." "Now leave me alone. I need to spread the word that Naruto stole the scroll so that I can make it look like he disappeared with it."

"Say why are you even here, Mizuki?"

"That's what I want to know, too, Shin-chan."

"I'm plotting my next step of my great revenge for everything Naruto has done to me and everyone else." Shinnosuke answered with a serious face."Naruto wants to have all the fun of his mission for himself." Next, his face lightened up. "What about you?"

Mizuki's eyebrow twitched. "Aaargh, this kid is so irritating." He tried to come up with something else but his mind drew blank. "Same here." He answered reluctantly.

"What's your plan?"

"As if I would tell you." Mizuki snorted.

"You know I would have left if you had just told me your lame plan."

"It's not lame!" Mizuki shouted. "I'm going to spread the word that Naruto stole the forbidden scroll and then I -"

"Told you. Lame." Mizuki's eyebrow twitched. "But I'll help you."

Mizuki tried to stop him but Shin-chan vanished with a Substitution. Then, he noticed a horrible stench that made him nauseous. He held his nose and looked down. "He substituted with a pile of shit?!"

Mizuki tried to find Shin with no luck. "Now, he is going to tell everyone that Naruto stole the scroll... wait, I was planning to do that anyway. With two people, this piece of information is going to spread twice as fast."

Wow, he is good at calculating. Unfortunately, this is Shin-chan we are talking about. So it's going to be different…

"Mizuki planned to tell people that Naruto stole the forbidden scroll."

First ninja. "Naruto stole the forbidden scroll?! I must tell the Hokage and the others!"

"Mizuki planned to purple that Naruto stoned forbidden scrolls."

Second ninja. "What the hell?! Naruto stoned forbidden scrolls? He is destroying valuable information. But what about Mizuki and purple."

"Mizuki planned to forbid Naruto from stroking purple scrolls."

Third ninja. "Stroking purple scrolls? What could that mean?" Then, realization hit the ninja. "Ahh, Naruto strokes his dick … no, no others too … and Mizuki knew about it but he wants to forbid others ..."

Thud.

"Mizuki plants forged purple scrolls and strokes Naruto."

Fouth ninja. Gasp. "That's why he never dated me. He makes his own own penises for … for … and poor Naruto. I need to tell the hokage."

A few hours later …

"I haven't done anything to Naruto! I hate Naruto! I hate him! I hate him! I hate him!"

"He must have forced Naruto into his sick sexual pleasures."

"In the end, he got jealous of other people and wanted him just for himself. In his twisted way, he loves Naruto."

Snap. Enough was enough. Mizuki wanted to endure the false accusations but, no, he couldn't take it any longer and spilled his great plan and Shinnosuke's meddling with it.

Later at the apartment of the Noharas …

RIIIIIING

Shinnosuke was told to see who the visitor was and opened the door.

"Who are you?"

"My name is Ibiki Morino, head of the Torture and Interrogation department. I've heard of what you did to Mizuki, quite impressive I must say. Would you like to join as an interrogator?"

"Hmm. Are there any hot babes there?"

"Some, but they are eccentric and have special tastes."

"Kinky. Okay, Shinnosuke Nohara is going to be an interrogator!"

In all prison cells, prisoners ceased whatever they were doing as they collectively felt a shudder run down their spine. One prisoner voiced what all of them thought. "Something horrible just happened."
