It was a, relatively, peaceful day in Konoha. They were still recovering from Pein's attack, but most of the village had been rebuilt. Right now Naruto was slurping down a bowl of ramen at Ichiraku's. It was then that he heard Sakura's voice calling for him. "Naruto!" she called out.

He quickly finished the bowl, and set it on top of a pile of others before paying, and leaving. Sakura quickly spotted him, and ran over. "There you are Naruto." she said, "I've been looking all over for you. Lady Tsunade wants us."

"Bahh. What does she want this time?" he complained.

"I don't know, but it sounds like a really important mission." she told him. At that he perked up.

"An important mission?! Let's go then!" he announced, running off to see Tsunade.

Celestia sat, thinking about what the upcoming days would soon be like. She had hired ninjas to protect her pupil, and her friends. Needless to say they didn't take it too well, and Twilight felt as though the Princess didn't trust them enough. She hadn't told them the exact nature of the guards, just that they were special, and that made it even worse.

It may not have seemed like a big deal to Twilight, and her friends, but it was a big deal to Celestia. She had even invited them to meet the new guards, and watch them be tested once they arrived. She trotted out onto her balcony, and looked up at her sister's beautiful night sky. She let out a sad sigh as she remembered the last time she'd seen a ninja.

Flashback

One thousand years ago a dark mare threatened to shroud all of Equestria in an eternal darkness. Celestia wielded the Elements of Harmony, hoping to defeat her, but Nightmare Moon wouldn't be taken down that easily. Having once used the Elements herself, she knew how to counter them.

Without the Elements to help Celestia it turned into a battle of sister against sister. Only the more powerful of the two would win this. Unfortunately the dark night was giving Nightmare Moon power, and Celestia was wearing ragged. Her breaths came in short, shallow gulps.

Celestia had given all she had, and it hadn't been enough. Finally she collapsed, accepting her fate. Nightmare Moon's horn glowed as she gathered up magic to finish up Celestia for good, and become the one, and only, ruler of Equestria. Celestia was only able to watch as Nightmare Moon unleashed the beam, sending it right towards her.

It was then that a unicorn jumped in it's path, and absorbed it. Nightmare Moon reared up in surprise. "Impossible!" she yelled, "You're just a lowly unicorn! How could you stop my attack?!" Princess  Celestia was amazed. This unicorn had just stood up to one of the most powerful spells in Equestria! Not even she could do that! Who was this pony?

Her thoughts were cut short as Nightmare Moon charged towards the mysterious pony. "Watch out!" she called to him with the last vestiges of her strength. He just looked at her with purple ringed eyes that made her shudder. Suddenly he disappeared, and reappeared right behind Nightmare Moon.

He then gave her a buck that sent her flying. She skidded across the ground, and stopped when she crashed into the mountain with enough force to form a large crater.. Celestia stared wide eyed at the scene. He then let out a shout, "Planetary Devastation!"

Suddenly the ground started shaking violently, and large chunks of earth ripped up from the ground, floating into the sky, and forming a large sphere. Soon even the mountain Nightmare Moon had been launched into was sucked up, along with her. Soon it's mass grew too great for the planet's atmosphere to hold, and in a great display of power the unicorn launched it out of the planet's orbit.

He turned, and walked to Celestia. "I have just created what shall be called the 'moon'." he said, "And I have trapped her in it. She will be back in a thousand years though. She will be significantly weaker though. Goodbye." With that he started walking away.

"Wait! called Celestia, making him turn back to her. "At least tell me your name?" she asked. He started at her with his purple eyes, once again causing her to shudder involuntarily.

"You may call me the Sage of Six Paths." he told her, then trotted off never to be seen again.

End of flashback.

Celestia let out another sigh as she stared up at the moon. "I just hope that these ninja are strong too." she whispered.

Naruto burst into the hokage's room where she was sitting behind her desk, and Kakashi was already there.. "We're here Granny Tsunade." he said, a tad unnecessarily.

"Ah. Naruto, Sakura, you're here. Now we can get started." said Tsunade, "I have already briefed Kakashi. You three shall be going on an S rank mission."

"An S rank mission?! Yes! I'm so excited!" Naruto said, pumping his fist into the air.

"Shut up and let her talk!" yelled Sakura, slugging him.

"Sorry Sakura." he said, on the ground. Tsunade cleared her throat.

"Ahem. Yes, well as I was saying. You all probably know the tale about the Sage of Six Paths visiting another world." she continued, "Well I have just found out it's true. I have just gotten a letter from the ruler of one of the planet's countries. Her name is Princess Celestia, and you will be guarding her pupil, and her friends."

"Wait a second." said Naruto, "What do you mean another world?" Tsunade let out a sigh.

"As I just said Naruto. You will be going to another world where the dominant species are ponies." she told him. This didn't surprise them unduly. After all they'd seen talking toads, and slugs before. "You will have to disguise yourselves though." she told them, "Fukasaku, and Shima will lead you there. Dismissed."

With that she dismissed the three to set off on their mission. Once they were gone Shizune asked the question that'd been itching at her the whole time, "Isn't it a bad idea to send Naruto off on a mission right now?" Tsunade gave a wry smile.

"Actually I think it'll be the perfect hiding spot." she said.
