A/N: Yo! This is the first installment of my challenge fics! It is the Itachi-sensei and His student challenge.

Here are the guidelines for it:

This takes place in the shinobi war. Naruto and Itachi, instead of separating, go after Madara (impersonation). While there, they end up Kamui'ed to a new universe.

Rules

1. Naruto must have the Eternal Sharingan due to Itachi and the Kyuubi's meddling.

2. Naruto/harem, Itachi/harem, and Kotaro/someone. Naruto must be paired with Eva, Chachamaru, Fuka, Fumika, Ku fei, Makie, Nekane, and others. Itachi must be paired with Shizuka and others. Negi does not exist so Negi's sister comes as a student.

3. Itachi must teach Naruto.

4. Itachi must room with Shizuka, Naruto must room with Eva and Chachamaru. From there on, it's obvious how they get together.

That is the challenge and this is a possible first chapter for it. It takes place right after Nagato uses Chibaku Tensei (Is that right?) and instead of Itachi stopping it, he casts Kamui as his last ditch effort...

Story starts now...

Groan "Itachi-san, where are we?" asked Naruto, who could only see the bright lights.

Hmm... I suppose my Kamui sent us somewhere, probably a different dimension, and if my guess is right... "I believe we are in a hospital," Itachi thought then said.

"Oh, great! Your up! I shall inform dean Konoemon!" Said a girl with greyish hair dressed in a nurses outfit, before she rushed out of the room.

"Who?" Naruto asked.

"I believe that he must hold a position of power around here, judging by her reation. Probably comparable to the elders, Kage, or Daimyo." Itachi mused out loud.

"How did you figure that?" Naruto asked.

"The girl was running off to tell him we were up like me and the rest of the ANBU were told to do by the Sandaime Hokage." Itachi explained, before gasping.

"Hmm, what is it, Itachi-san?" Naruto asked.

"Y-your eyes. They have a sharingan and a Rinnengan!" Itachi explained. "But how!"

That would be my doing, a giant voice rumbled. After all, I modified yours into an eternal and gave Naruto the means to achieve that level of power, as well as unlocked his Rinnengan, which was the bloodline of the Uzumaki. I have also released your full mental capabilities and gave you both the ability to use, what the people here call, 'magic'. However, you shall both need training in it.

"K-k-kyuubi, how are you speaking like this?" Itachi questioned.

I am using the connection my host and I now share from the release of his powers. If your pathetic questioning is over, I am going to sleep. The Kyuubi finished before cutting the connection.

They would have woken Kyuubi back up, had it not been for the door opening to reveal...

An old guy with a long beard!

"Greetings, I come in peace, take me to your leaders," The old guy said as even Itachi facefaulted.

"We're not aliens!" Naruto exclaimed.

"Well, in that case," the dean started, "how about you date my granddaughter?" He asked before getting hit in the head with a mallet that appeared out of nowhere.

Naruto would later swear he heard a girl's voice saying, "Oh grandpa!" right after it struck.

After explaining their tale to the dean, the dean said "hmm, I suppose I could set you up at this school as the new english and gym teachers. You could also teach homeroom class 2-A. Please get me Eva, Chachamaru, and Shizuna."

A few minutes later the door was opened by a blonde haired ten year old, a green haired maid with pointy ears, and a tall blonde girl with "F-sized cups!" Naruto exclaimed.

Everyone looked at him weirdly at that, so Naruto explained himself, "My old mentor was a huge pervert who had an obsession with breasts, and often forced me to find the largest ones and guess their sizes."

"What did you call us here for, old man?" the blonde ten year old asked.

"Now, now, Eva-chan, the reason I called you here is so that you can take your new roomates home. Naruto will be rooming with you and Chachamaru, while Itachi will be with Shizuna." the old man explained while pointing his finger at each one as he said the name so that they wouldn't get confused.

Done, I may make this like Evil Guy's fantasies or I may just make this challenges, you decide!
