Weak Gamer in Naruto

Kakuzu had sweat running down his forehead as he saw the gigantic slash on the ground. Turning towards Shinju, he noticed the kid had a bandaged sword with the tip released.

Everything turned silent, with Hidan and Kakashi looking at the cut on the ground, Kakashi had disbelief on his face, while Hidan had annoyance and slight fear.

Shinju grinned as he felt the comfortable feeling of the hilf of his sword, he brought the blade in front of his face and put it on his forehead as he smiled.

"Kakuzu, you better bring everything you have if you want to survive this battle"

Kakuzu groaned in annoyance at being provoked, but he also knew that he did not have a choice now, his back suddenly bulged, and the masks on it floated down.

The skin on his back exploded, and 4 black monsters appeared behind Kakuzu, they all had different masks, with different colours on them.

"Fine kid, but don't say I am bullying you"

Kakuzu looked back, and the fire heart and wind heart suddenly started fusing together, becoming an even bigger monster, with the 2 masks being side by side.

The fire mask opened its mouth, followed by the wind, and it released a huge beam of flames, with wind encircling it, making it hotter and stronger.

Boom!

The air turned red, and Shinju smirked as he dodged to the side, the flame hit the ground where he was, and it exploded into a crater of 20 meters.

Shinju dashed forward, and he flew on his knees, sliding under the flame beam before standing back up, the Lightning mask behind Kakuzu opened its mouth, and it sent a laser towards Shinju.;

"Lightning Release: Laser Cut!"

A screeching sound was heard as the laser flew towards Shinju, with two attacks directed towards him, Shinju jumped into the air, and the attacks followed.

Boom!

A cloud of smoke appeared, and Shnju clamped his hands with the clone, before the clone spun him around at a high speed, creating a cyclone around the 2.

Boom!

Shinju was sent flying towards Kakuzu, and he flew past the 2 attacks as his body flashed toward Kakuzu.

Kakuzu flashed his seals, and a water wall was created in front of it, Shinju sliced it open, along with the water clone behind it.

"lightning style: False Mock!"

A lightning blast was sent towards Shiju, but Shinju caught it with his sword tip, and then he redirected it towards the earth's heart behind Kakuzu.

"Impossible!"

The earth clone was shattered amongst Kakuzu's shout, and Shinju smirked as smoke appeared behind him, stepping on the clone, he jumped at Kakuzu.

Boom!

Kakzu was kicked in the chest, and he was sent flying back, and through a huge line of trees for tens of meters, the fusion heart sent a flame beam towards Shinju, and he cut it in half with his sword.

Shinju was sent flying back from the force, and he flipped in the air as he landed on the ground, the fusion heart kept sending beams at him, and the lightning heart was shooting his laser cut towards him as well.

Body flicker technique, suddenly 5 Shinju flashed around the place, and he surrounded the masks at such speed that they couldn't find the real one.

"Searing Migraine!"

The fusion mask sent a huge beam towards them, and the ground was turned into ash as a huge beam enveloped everything in its path, turning everything to ashes.

Shinju easily dodged the attack, and he flashed towards the Lightning heart, his eyes cold and ruthless as he thrust towards the heart with his sword.

"Lightning Style: Hellish Thrust!"

Shinju surrounded his sword in Lightning release Chakra, and it was boosted even more with the sword turning it into Sage chakra due to its property.

The lightning changed colour, and it turned green in colour as the sword was thrust forward.

A sound akin to glass shattering was heard as Shinju fully extended his hand, the world in front of Shinju lost all its colour for a split second, and then it returned to normal.

But it was different, a hole about 1 meter in diameter, and 2 miles long was in front of Shinju, everything in that diameter was turned into ashes, with nothing remaining.

No explosion was created since nothing exploded, instead, everything turned into ashes instantly, a green light flashed for a moment before everything returned to normal.

The lightning heart was nowhere to be seen, and Kakuzu started trembling as he looked at Shinju, he only had the water heart, fire and wind heart left.

If it goes on like this, He would definitely killed...

Not caring about Hidan, the beasts started flying away from Shinju, following Kakuzu who was running away, his speed faster than lightning as he ran.

"You think I am gonna let you run?"

Shinju sneered, if someone tried to kill him, he would kill that someone first, he would never let an enemy run from him.

His body vanished as he used body flicker, and not only that, his feet were enhanced and surrounded with lightning chakra, increasing his speed to the max.

This was his fastest.

The world seemed to zoom out around Shinju as the forest blurred him, the distance between Kakuzu and him was getting closer and closer until he was right behind him.

"Lightning Style: Hellish Thrust!"

Again, the world turned white, and Kakuzu felt his eyes open wide as he looked down, everything below his neck was gone, only leaving his legs from the knees down there.

In an instant, his mind turned dark, and he lost his life almost immediately. The thrust continued until it met a small hill, going through it and leaving a meter-wide hole inside.

Boom!

Shinju fell to the ground and slid for a few meters. As his feet dug into the earth, he sheathed his sword and let out a breath, releasing steam from his mouth.

Shinju felt his jonin level chakra start to be drained, it was barely a genin amount left as he used his strongest attack 2 times in a row.

He has to balance the natural energy his sword naturally generates, or his chakra would go rampant, and might even injure him, if not worse, turn him into stone.

But it is much easier than Sage mode where you have to constantly balance the 2 energy, he only has to make his chakra stay the same amount as the natural energy from the sword.

Shinju stood upright, and he walked forward while panting, he leaned down and he took Kakzuzu's head into his hand, he could extract information from it.

"You were a worthy opponent, Kakuzu!"
