Naruto the next demon king

chapter one

Naruto Uzumaki was sitting on the swing after failing the graduation exam for the third time. "Hey Naruto." A voice said this voice was Mizuki. "There is another test you could do."

Timeskip two hours.

Naruto was reading the scroll trying to figure out the shadow clone jutsu. "Why can't- OW!" Naruto yelled as his thumb was cut and in a flash of light a bundle of clothes around a black  Katana and a piece of paper with his name on the envelope.  Naruto grabbed the note and began to read.

'Naruto I know not who you are but all I know is that you are my successor for the demon king. My name is Akuto Sai and I am leaving you the blade of the demon fox made from demonic metal. Also I am leaving magical library to you it's housed in your blood. The clothes are for coolness the jacket is made from my dragon Peterhausen's scales so it can protect you from alot of shit. Yours truly the demon king Akuto Sai.'

"COOL!" Naruto said as he picked up the bundle he tried the shadow clone jutsu and succeeded. Naruto popped them. He was battered and bruised because the clones fought back.

Iruka walked up to see Naruto. "Naruto what is going on!?" He yelled Naruto handed him the note.

"Some dude named Akuto Sai left that and this in a blood seal the note is addressed to me." Naruto said. "Mizuki told me about the second.... The fucker lied!"

"Oh good job Naruto you caught me." A voice dripping with venom said as a huge shuriken came toward them as Naruto was shielded by Iruka. As Iruka's blood hit Naruto's face. Naruto's body began to pulse magical energy Naruto pushed the giant shuriken out of Iruka as he stood up his upper clothing was disintegrating. "THE DEMON AWAKENS!!!"

Naruto stayed silent as he stuck out his arm the sword of the demon fox flew at him to where the handle was in his hand in a split second. A large magic circle appeared at this all jinchuriki look towards Konoha. 'the King awakes.' they all thought for no reason.

"Mystical fire devastation." Naruto said as a huge fire ball launched itself at Mizuki at supersonic speeds. At this moment Mizuki knew he fucked up.

"Oh shit...." Mizuki said as he tried to dodge it keyword tried. The fireball was faster than what Mizuki could move. The night air filled with screams of pain as Mizuki's legs was burned off. Naruto was about to pass out when the Hokage appeared.

"Sir Mizuki was the one behind Naruto stealing the scroll then Naruto stopped him. Naruto passes in my book." Iruka said.

"Eh." Hiruzen said.

"Try the Kage Bushin for paperwork..." Naruto mumbled. Hiruzen blinked then was banging his head against a tree the commanders of the Anbu joined him.

"Take Iruka to the hospital. Do what ya want to Mizuki before taking him to the T&I department." Hiruzen said as Kakashi appeared.

"I can't..." Kakashi said as he looked at Naruto. "Find Naruto..."

"Kakashi take Naruto to the Hokage tower." Hiruzen said.

"Yes Hokage-sama." Kakashi said as he grabbed the blonde and took him to the tower.

Hiruzen grabbed the black bundle and the sword he went to the tower.

In Naruto's mind.

"Oh come on!" Naruto said. "Damn. Fucking. Sewer."

"Damn kid." A dark voice said Naruto chose a random direction.

"What is that damn fucking voice." Naruto said as he came to a cell. "The fuck?"

"You have a very nice friend in your head." A calm voice said. "She is quite cute to."
