1 Forbidden Jutsu: Fukurokuju

"There's no time left, we must hurry."

A cold and heavy voice emerged from a boy with natural blond hair. He had a tenseigan, a Jogan, and a short temper.

Boruto Uzumaki. In his current-prime. (15 not bloody 20.)

He was currently in the middle of doing innumerous hand signs. Despite the chakra control he had inherited, he still needed an unimaginable amount of hand signs to perform the following forbidden jutsu.

He and another similarly aged boy were in a brightly lit cave. A dancing flame illuminated the cave in a wild yellow hue.

Kyoto Uchiha who had an appearance extremely similar to the young Izuna Uchiha had an uncanny amount of sweat streaming down his figure. He had never been worried in the slightest before, so this was quite odd. He had two mangekyou sharingan and was wearing ragged black robes. His chest was revealed showing off a toned body and a criss-cross pattern of white-skin patches. They were Hashirama cells gifted to support his mangekyou sharingan.

"Boruto, how much longer will we need? I sense something coming. It is extremely far away but enclosing on us faster than I can calculate."

His voice was as raggard as his robes. Unlike Boruto he was far outmatched in the current era of planet-devouring aliens. The two were far from relative.

Boruto remained cold and stoic as he grumbled.

"A couple more minutes..."

His hands were still going at the hand signs without breaking. They had long become blurs.

Kyoto was impressed by the show of hard work. He rarely needed more than 7 hand signs for ANY Jutsu.

Not that he used many jutsus in combat. His Susanoo and mangekyou abilities had proved to be far more than enough for his common enemies.

Kyoto currently had a loose man-bun and a lazy look on his face.

He was currently sending out chakra waves to detect Shibai, the otsutsuki God, who would reach them any minute now.

"We have a minute at most."

The cave shook.

Dust fell from every corner.

Boruto cursed bitterly.

"How long can you hold him off?"

Kyoto tousled his hair ambitiously.

"Although I can cast Dosojin and partially corrupt him with cursed stone, he is far too strong for a mangekyou Jutsu to affect him. The best hope I have of fighting him would be my Susanoo."

Kyoto laughed nervously. He was quite pitiable as of now.

"But even then, Shibai smacked Otou-san's Susanoo to the side like a fly.

Boruto sighed.

"I'm done. Ready the Yata Mirror. This process cannot be undone."

Boruto wasn't done at face value but he would be done in no more than a minute. His hands were still rushing the signs perfectly.

Boruto's tenseigan had gone dull. His monstrously high chakra levels were deteriorating within him. The Forbidden Jutsu: Fukurokuju used so much chakra that it felt like he was throwing buckets of water into a desert.

The two enclosed each other.

Kyoto put two sweaty hands together in a meager clap.

"Susanoo."

A strong air of rumbling rose.

And with it, an entirely black Susanoo formed. White lines crossed over it wondrously. It wasn't a perfect Susanoo but it had developed armor.

It carried the yata mirror which had been dyed black and it also carried a devastating black flame.

"Put that black-flame launcher away. It's wasting chakra. And make sure the pain doesn't affect your mind."

Kyoto laughed cheerily.

"It's a package deal and don't worry, I took the drugs."

Boruto shook his head moodily.

"You sure you wanna do this? There are no turn-backs."

Kyoto's face went blank.

"Shibai is here."

Boruto cursed, instantly speeding up his hand signs.

A man veiled in shadows appeared at the front of the cave. Although the cave was packed with a huge skeletal titan, the man was far from nervous.

"The Yata Mirror? I think I'll enjoy that in my collectio-."

Kyoto roared as his left eye opened in unimaginable pain.

Blood had gathered and red slits formed all over his eye.

He was not holding back the smallest drop of chakra.

"Dosojin."

A black-light engulfed all that was in Kyoto's line of sight.

A black light halted just before Shibai. No matter how hard Kyoto pushed his chakra into his left eye its powers were limited by his mortal body.

The entire cave soon came crashing down as its stone was cracked and corrupted. The effects of Dosojin were taking place.

Through the rumbles, only Kyoto's Susanoo stood tall.

Boruto screamed as he sprinted towards Kyoto.

"QUICK. KYOTO."

The two leaped for each other in the air, Kyoto left his Susanoo behind.

A black figure shot out at a speed faster than light, ready to intercept the two.

Kyoto sensed it with the chakra waves he was constantly sending out.

"Damn it."

Shutting his left eye firmly he braced himself.

Boruto was still sprinting, only a few meters were left between them.

"Dosojin."

The nostalgic sound of the sharingan ran out. Kyoto's left eye felt like it was being pierced by metal needles.

Soon, the black light spread throughout the land which was no longer blocked out by cave walls.

An expanse of hazel stone turned into a sea of cracked rock.

The figure going at light speed briefly halted to stop this destructive Jutsu.

"Send me away Boruto."

Boruto had a look of animosity in his eyes as they darted to Shibai's arrogant figure.

"For Kawaki."

"Forbidden Jutsu: Fukurokuju."

Boruto had been performing hand signs the entire time.

Soon, a pillar of pure ethereal white descended with a boom.

BOOM.

The white light bounced off the ground and flew off in all directions. Everything it touched was turned a shining white before disappearing without any trace.

Boruto was left panting on the ground, his tenseigan flickering in and out.

"Good luck."

And the figure of Shiba descended in a calm attitude.

A sense of calming that became frustration.

"It doesn't matter. He won't survive that chakra density."

Shiba realized that Kyoto had indeed gone through with the Forbidden Jutsu.

For a short instance, rage devoured Shiba's eyes.

The entire mountain expanse was turned to dust particles in an instant. The price of Shibai's short trance of rage.

Shibai's figure looked around in a mix of hatred and confusion.

"They escaped?"

"With my yata-mirror?"

Shibai felt like stomping out half of the puny planet he was standing on.

It was then that a faint purple apparatus started growing larger.

Shibai looked to his right in frustration.

"That Susanoo-."

Boom.

A perfect purple Susanoo covered in armor and exuding power crashed down like a comet.

Its remains burnt into pure chakra as the figures of Sasuke Uchiha emerged.

"Stay back, Shibai. This World is not yours for the taking."

Sasuke who was wearing his usual black cloak had aged with time. But with age came wisdom and power.

The eye of Sasuke had returned. The fabled rinnegan was back.

Shibai chortled. {Why is Shibai back in the third dimension? Because he just is 🤷. Deal with it hobos.}

"Human. I care so little for you that I'll let you have this item. I'll be taking it back in a minute."

Shibai chucked out an entirely black blade.

Sasuke instantly took a liking to it.

A vortex of space swirled open, distorting the natural world.

"No, I don't think you will be taking it back in a minute."

Pop.

Sasuke Uchiha was gone. Disappearing into a rift of space-time, he had gotten away with far more than he had imagined.

Shibai let out a wicked smile. This planet was quite amusing.

"Fuck."

In a deserted area of desert deep in the land of Wind, Kyoto Uchiha was lying down panting.

His eyes turned back into normal 3 tomoe Sharingan before swirling into entirely black eyes and the sweat on his skin intensified due to the blazing sun.

It looked like a tornado had just hit and despite the devoidance of trees in the desert tree trunks, bushes, and rock clusters were scattered all around the desert.

The shinjutsu had hit a few unidentified targets.

Kyoto Uchiha felt like death was taking its time really slowly.

He had exhausted most of his chakra in only a few moves.

He had never used Dosojin on an entire mountain expanse and it had been a futile attack anyways.

The man bun of Kyoto had become disheveled and disarranged.

A lonesome desert bird soared over Kyoto's laid-down figure.

"Caw."

Kyoto sighed.

"Where did I even get transported back to."

His hands formed a telescope.

"Well, I should be near the village hidden in the sand. That or in some random desert."

"Time waits for no one."

Kyoto yanked himself up and began strolling north.

Going with the flow was all that he could do in this situation.

Aiming his hands upwards Kyoto did some frail hand symbols before opening his mouth as wide as he could. His lips felt dry and compressed.

"Water style: Water fountain Jutsu."

A silvery and sloshing fountain of water rose from his hands into the air. It soon fell into his mouth lavishly.

"That's the stuff."

Kyoto wiped his mouth and rolled his shoulders back.

There was truly no end in sight. Just a blue sky that seemed to go on forever.

Kyoto ambled on and on until his distraught figure met upon an Oasis.

Making himself at home, Kyoto assigned himself a small home consisting of a bundle of sticks assigned in a spiral.

Leafs formed a bed.

The sun had already fallen by the time Kyoto was done.

"Happy fifteenth birthday, me."

And with that, the journey to save the world began.
