Naruto: The Template System

Konoha.

Third Training Ground.

"Come on, Uncle Red Hair"

Naruto shouted loudly, cheering for Kozuki as the exciting fight started.

"Idiot, my big brother would win."

Sasuke bragged about Itachi as there was no way he could lose.

"Here I go"

Kozuki smiled hearing the voice of Naruto and then said while looking at Shisui and Itachi in front.

The expression on the face of Itachi and Shisui also became serious as their eyes turned red with three tomoe spinning in them.

Whoosh...

Boom...

Kozuki disappeared from his place, leaving the cracked ground underneath as he appeared in front of them, his sword slashing at them horizontally.

Shisui and Itachi were prepared as just when the sword was about to reach them, they flashed back, avoiding the attack, and their hands weren't idle.

"Fire Style Fire Dragon Jutsu"

"Wind Style Wind bullet Jutsu"

A Fire dragon sprouted out from the mouth of Itachi as it roared towards Kozuki.

Shisui didn't want to be left behind as fast wind bullets rushed towards Kozuki.

Kozuki didn't back down as he kept moving forward, and with his sword, he quickly deflected the bullets, and the fire dragon suddenly seemed to be hit by something extinguishing.

Kozuki appeared in front of them as two consecutive slashes drowned them.

Poof...

But they suddenly burst into smoke as Kozuki heard wind cutting sound and saw two big Fuma Shurikens with flames around it cutting towards him.

Clang...

Poof...

Kozuki easily deflected the first one, but as his blade touched the other, it burst into smoke as Itachi appeared in front of him and his eyes had a different pattern.

"Tsukuyomi..."

Kozuki suddenly found him bound as the world around him changed, and the sky turned red.

"I win Sensei"

Itachi appeared in front of Kozuki as his face had a victors smile on it.

Itachi naturally didn't want to torture Kozuki as he just wanted to make him immobile.

"Oh, really"

Kozuki didn't seem nervous being bound as he suddenly smiled, and Itachi suddenly had a bad premonition.

Kach...

A powerful red aura suddenly shot out from Kozuki, and cracks began to appear everywhere, and soon the world broke apart like a mirror.

Shisui and the rest of them who saw Itachi Kozuki motionless for a while were stunned as Itachi suddenly sprouted out a mouthful of blood.

"Good Jutsu, but sadly it won't work on me."

Kozuki said while looking at Itachi, who stood up after wiping the blood from his mouth.

"As expected of you, Sensei."

Itachi wasn't much surprised as he knew there was no way defeating Kozuki could be this easy.

Whoosh...

Shisui appeared beside Itachi, and then both of them looked at each other and nodded.

The eyes of both of them spun as immense Chakra erupted from them, and around both of them, red and green Chakra appeared.

Both of them increased the output of the Chakra. In the unbelievable eyes of Naruto and the other genin, soon two massive monster's tens of meters long appeared around Itachi and Shisui.

"Big Brother is so strong"

Looking at the Susanoo, with a colossal gourd and a shield, Sasuke was shocked.

The Susanoo of Shisui was also around the same height as Itachi, with two long swords in both hands.

"This..."

Feeling the power of Susanoo, both Itachi and Shisui were surprised.

In the past, they could take their Susanoo to this level, but their eyes would bleed, and they won't be able to maintain Susanoo for much longer.

But now, there was no sense of discomfort, and they could use Susanoo as long as their Chakra didn't run out.

"So, it's still not Perfect, Susanoo"

Kozuki was a bit disappointed as he had expected that with the help of Pure Gold, they might reach Perfect Susanoo.

But even so, their strength had increased a lot; just maintaining this form of Susanoo without blindness was a massive boost for them. (Around the level of Itachi during his fight with Sasuke)

Shisui and Itachi tried to put more Chakra in the Susanoo, but it didn't change anymore, and they were also slightly disappointed.

It seems their eyes haven't reached the next level, Eternal Mangekyo told by Kozuki.

"When did they get so strong?"

Kakashi was confused as he couldn't understand the reason behind the sudden increase in their strength.

He has seen the Susanoo of Shisui before, but he could hardly use it for a minute before his eyes would bleed.

But now Shisui seemed totally fine, and the same was for Itachi.

Finally, Kakashi looked at Kozuki as he guessed that he may be the reason behind their sudden increase in strength.

"Be careful, Sensei"

Shisui reminded Kozuki as he swung one of his swords right towards Kozuki.

Boom...

Kozuki jumped up, dodging the giant sword, but suddenly, a shadow over his head saw a red shield striking down on him.

Boom...

Kozuki brought his sword in front of him, blocking the attack, but he was shot down by the force of the shield.

Flipping in the air, Kozuki safely landed on the ground, but a green sword once again came into his vision.

This time, he didn't back down as his sword suddenly turned dark, and crackling red lightning flashed around it.

The small sword collided with the giant sword, but the small sword cut right through it.

"What!!"

Shisui was surprised and wanted to attack again, but Kozuki suddenly appeared before him, and the blade with red lightning crackling around fell on the Susanoo.

Like Paper being ripped apart, Susanoo made a similar sound as it was cut open and a blade was placed on the neck of Shisui.
