A Full Day of Torture

Naruto groaned as he awoke from his bed. He would really have to stop doing those late night practices. Even with the fox in his gut, they took a lot out of him. The fox was even holding back as much of its healing abilities as possible to make him stronger, which he was grateful for, but it still drained him.

'Time for another day of pure, utter, torture. However, I finally got the hang of Sky God Style: Rasenshuriken. Sure it took me like three weeks, but I did it.'

Naruto quickly hoped out of his bed, and rushed to the bathroom. While brushing his teeth he thought back to his old life in Konoha, and how much he missed everyone there.

'I'll never see Sakura again. Nor will I see granny and the perverted sage again. Hell, I can't believe I'm saying this, but I even miss Kiba, and Neji, even though he was more bearable. The one I'm most likely going to miss is Hinata though. I can't believe I never noticed her feelings for me. When people called me dense the most have meant that,' Naruto thought. However, he quickly shook himself out of his negative attitude.

They wouldn't want him to be sad over them. If he was it would be like he was spitting on their memories. He couldn't do that. He still had his ninja way to uphold, and honoring them was the best way to uphold it, or at least how he saw it.

He finished getting ready and slipped into his orange jumpsuit, before running outside of his room. Sasuke had training before he did. Right now he had to reach Kai and get going to his room.

He yawned as he walked down the hallway. Fiore's history was almost as boring as the Elemental Countries'. The only interesting bit was this guy, Merlin, he though his name was, who created magic. He was a lot like the Sage of Six Paths. Heck, even one of his descendents, Zeref the Black Mage, even up going crazy, like Madara, and went out for world domination.

He sighed. Why it was, just his luck that every world he went into had someone who wanted world domination. Hopefully, this time he wouldn't be the sole protector, or at least have a large part of the future riding on his shoulders, but he still wanted a piece of the action. At heart, he stilled loved fighting, which is part of the reason he hated learning about history. However he was excited today.

Kai and Rai said they would start helping them with their secondary and tertiary Magic's after today. He smiled. Learning Energy-Make and Heavenly Body Magic was going to be awesome. He couldn't wait.

Sasuke walked onto the usual platform where he would spar, either with Naruto, against Naruto, or against Rai.

Speaking of the God, he just now walked out of the hallway in front of Sasuke.

"Sasuke," he said.

Sasuke nodded in response.

"We'll be doing something different today. I want you to work on any technique you want. I'll be teaching you a special move of mine that improves speed and defense over a certain amount of time. It's called Lightning Coat. Once you get down those basics we'll be working on something else, however that will have to wait, now get started," Rai said.

Sasuke nodded before coating his hands in black lightning. It was going to be a long day.

Kai looked at Naruto with slight irritation gleaming in his eyes. Why did the boy have to be late, all the time? It was ridiculous! Every single day, back-to-back, he was just late. It was beginning to anger him.

'I'll teach him that technique. It should teach him to not be late on my terms,' Kai thought darkly.

He smiled an evil smile, before opening up a book. He forced Naruto to recite what he learned from his so-called studying from last night, however, as usual, he came up blank.

Kai growled, making Naruto take a step back.

'Maybe I should have studied instead of completing the Rasenshuriken,' he began to think.

Kai sat down on a stool behind him as Naruto opened his book.

"Who was Zeref," Kai asked annoyed.

"Zeref, 'The Black Mage,' or 'The Killing Mage.' He was a master of the Black Arts and created many demons which wreak havoc on the world at present, for example Deliora or Lullaby. He witnessed the deaths of many people around 400 years ago. During this time he became cursed and took all life around him, unintentionally. Supposedly he alighted in the ancient land, causing havoc and making demons. He was sealed away. He's said to be the darkest, most evil mage in the history of the world," Naruto said.

Kai nodded. He was very accurate in his knowledge. However, Kai expected as much. Having learned all about their past lives with Rai it wasn't surprising he knew about he memorized Zeref, after all, the two seemed to know a lot about this Madara character, so why not Zeref. They were essentially the same, in certain aspects. However, both boys admitted that if the two fought mass destruction would occur. They were even unsure who would win.

Kai was glad the two boys had killed him then. From the technique his subordinate supposedly knew, Kamui, if they found a way to open a rift into this dimension it would be catastrophic. Many of the masses would die. Dragon's and God's alike would come to stop the two and, most likely, many would fall. Well, that's what would happen if Zeref wasn't sealed away.

Kai nodded as he kept this up, still teaching his overactive student, who was acting up once in awhile.

Sasuke coated his hands in black lightning again. He was tired, no, exhausted. Calling upon this Lightning Coat wasn't easy. He'd been at it for about three hours, and the time limit for his training session of the day was almost up. He was aggravated at that. He wanted to master this technique, but it seemed he wouldn't get the chance. In all honesty, he hated feeling that weak. However, he vowed he would get the technique before the end of the week.

"Enough Sasuke," Rai called. 'Amazing, after about twenty failed attempts he still has enough Magic to keep going. Lightning Coat is by no means gentle on the Magic reserves. Even when I use it I feel a slight drain, yet to attempt to use it twenty times. It's nothing short of impeccable.'

He stopped his lightning, although from the scowl on his face, he was exceedingly angry about having to do so. As he walked down from the stairs he felt dizzy. He knew if he was back on his first day he would faint right here and now. He did it the first two weeks of being here. Those were ugly scratches he got from falling. However, it made him more durable so he was okay with it.

As he reached the ground he saw Naruto and Kai walk out of a nearby hallway.

"Hey, idiot," he said.

"Hey, bastard," Naruto responded.

He smiled. They still acted exactly as they did when they were kids. Even with the exact same names they called each other. It was rather refreshing. As he and Rai walked past him the two exchanged a nod, smiling all the while, well Sasuke was smirking, before they both disappeared from the other's line of sight.

Naruto walked up the platform, before turning to look at Kai.

"I want you to learn how to heal yourself. All Sky God Slayers can do it, meaning I'm going to be attacking you. Not lightly by the way. It will be brutal. This will help with endurance. Now, to heal yourself all you have to do is concentrate Sky God Slayer Magic onto the wounds and it will do the rest. It may sound easy, but it's a lot more difficult than it sounds. Now, let's get started," Kai said.

And with that, a brutal beat down of Naruto failing to heal himself each and every time occurred It helped with his endurance, however he was so badly cut, dazed, and broken that he literally couldn't walk down the stairs. Needless to say Kai was a lot harsher of a trainer than Rai was, however Rai was much of a stricter teacher on knowledge then Kai. As poor Sasuke was learning at the moment.

Lunch and dinner had both ended, and Naruto and Sasuke were standing on the platform preparing for their brawl. Well, more of a slugfest, as it always ended that with, with Kai and Rai having to stop the fight before the two hurt each other too badly. Not that they didn't already succeed in doing it to their students. The hypocritical actions of it were slightly entertaining.

"Begin," Rai said.

As soon as he said this Naruto took off, dashing towards Sasuke with immeasurable speed. Sasuke was shocked; he had never seen Naruto take off so quickly. He quickly activated his Sharingan, for he knew he couldn't keep up with that type of speed without it. His eyes weren't trained at that level quite yet.

Naruto lashed out with a quick punch, however the raven-haired boy caught it easily, as if he had already saw the move coming. He smirked, before kicking Naruto in the chest, easily sending the boy flying, and crashing into the ground.

Naruto groaned as he stood up. He wouldn't let Sasuke beat him. No way, he was Naruto Uzumaki for a reason. He rushed forward going in with an axe kick, however Sasuke just blocked it with a high block. He lashed out with a reverse punch, but Naruto twisted to the side, pulling his leg free from Sasuke's grasp, and lashing out with a spinning hook kick, straight to the boy's temple. Sasuke saw the move coming, however he wasn't fast enough to avoid it, and as punishment paid the price. He was sent careening into the ground, skidding slightly as Naruto took advantage of this.

Sky God Slayers were naturally faster than Lightning God Slayers as they were built for speed, befitting Naruto. However, Lightning God Slayers were much more bulky. This advantage of speed allowed Naruto to reach Sasuke quickly.

"Sky God's Axe Kick," Naruto roared bringing down his heel, which was covered by black winds.

It slammed down onto Sasuke, however he caught the kick, his hand coated in black lightning.

"Lightning God's Bellow," Sasuke roared, releasing a torrent of black lightning from his mouth and directly into Naruto's chest, sending the Sky God Slayer flying.

'Oh hell no. I'm not losing to this guy,' Naruto thought, before he landed on both feet.

"Sky God's Raging Tornado," Naruto roared, before coating his fist in black winds. He thrust his fist forward, sending out a powerful blast of black winds, however it was deflected by Sasuke with a Lightning God's Raging Storm, but that was what Naruto wanted.

He appeared directly in front of Sasuke, generating a spiral of black winds surrounding his hands.

"Sky God's Boreas," he roared, letting the spiral loose. It caused a massive black whirlwind, launching Sasuke into the air with multiple cuts on his body.

"Sky God's Dance," Naruto roared as he finished up his combination attack. Two giant streams of wind flew from his hands, launching Sasuke even further into the air.

"Not happening Naruto," Sasuke roared as he flipped in midair. "120mm Black Lightning Cannon," Sasuke said. He generated black lightning between his open palms before firing it off as a beam towards Naruto, however, he was just barely able to dodge it.

'Damn it. That was my strongest and fastest spell I know, not counting Chidori. But I want to save that for Rai. But I can't lose to Naruto. No way. It looks like I'll have to take Naruto down with my ace,' Sasuke thought.

Naruto was thinking along the same lines, as all of his moves were read by Sasuke's Sharingan. The only reason he got off those attacks was because he was faster than the Uchiha.

"Chidori," Sasuke roared in challenge.

"Rasenshuriken," Naruto roared in response.

The large amount of lightning Magic Sasuke channeled into his right hand was immense. The high concentration of electricity made the sound of a thousand birds chirping.

However, the sounds response was one of equal magnitude, a loud screeching noise. The black Magic fuma shuriken held countless microscopic wind blades inside of it; so many that even Sasuke didn't know the exact amount even with his Sharingan.

Originally Rai and Kai would have stopped this, however they both knew the two had been practicing these spells by themselves. Plus they could tell they had powered down the techniques to just severely injure, not to kill.

Naruto jumped towards Sasuke, as Sasuke fell towards Naruto. The two opposing spells collided, causing a massive explosion of black lightning and black wind, sending both mages spiraling uncontrollably into the air. They reached the ground with a loud thud, landing on their backs. Both were unconscious. They force of the collision was to great, and their bodies hadn't reached the endurance they used to have, and as such they couldn't take the stress.

Rai and Kai looked at each other, smiles on their faces. They had sure picked interesting boys.

Hey everyone its Kuma Akuma. Anyways, I'd like to point at the next chapter will be the last time you see Rai and Kai for awhile. They will also be working on the secondary and tertiary Magic's next chapter. Also, the Rune Magic change to Heavenly Body Magic was not my idea. It was Emperor of Pandemonium's. Finally I would also really appreciate it if you guys would check out my other story, White Tigers. It would be appreciated.
