Soul-Slicer

General POV

Everyone watched how Ishizu took a sword out of his body. Some found it weird, yet none believed that it could do anything against the monster towering over them.

"He… he hahaha!" Jack laughed from above, seeing the 'mighty' weapon his opponent revealed.

"Your puny weapon will do shit against me. I will crush you, your dreams, and everyone else you hold dear. Nothing stands in my way. I am GOD."

From the back of the Susanoo, massive black wings sprung open, and it soared into the sky.

By the sage, what else did this guy have up his sleeves? Oh wait, I am giving him those powers. Upps?

"Kneel before the might of Jack, your God. The one who dominates you all!"

With that, Jack's Susanno charged down towards Ishizu like a god coving the ground in his shadow. Meanwhile, Ishizu closed his eyes while grabbing his sword with two hands above his head.

Crouching down, Ishizu felt his chakra getting drained and sucked inside the sword, lighting up the seals that were placed on it.

Any Jonin would get die from the chakra exhaustion and even a Kage would have trouble keeping this up, but Ishizu had enough to just pull this through.

"Die!"

The only response Ishizu gave as he swung the sword was:

"Its name… is Soul-slicer."

God. That would be the name the citizen gave Jack when they saw what he was capable of without his Chi.

Many gave up the hope of defeating such a powerful opponent and others such as Tigress, who were prideful, had a slither of hope for Ishizu to win.

Only one old turtle glanced down towards the small human that stood against the behemoth. Not an ounce of doubt was seen on his face. He believed in the human Po sent them.

~WHUUUSSSHHHH!~

So when everyone saw how the attack from Ishizu sliced through the Susanoo like a hot knife through butter, many couldn't help but drop their chins down to the ground.

Not literally, but the sight of such action made many question if they were seeing a dream or if this was the harsh reality. What they were witnessing was impossible.

Ishizu POV

"W-what? I-impossible! H-h-how?" Jack gasped when his Susanoo disappeared and his body fell down to the ground.

I fell on my butt, watching Jack's eyes become lifeless. There was no blood. His body didn't have a single wound on him, yet I was the one moving.

Soul-slicer. The name of the weapon does what its name implies. Through countless seals, I managed to create a weapon that no armor, no matter how durable, can block its attack.

Once it is locked on the target, it will follow the target through time and space with no chance to escape. A weapon that targets the soul of the enemy and like a regular sword, instead of slicing through flesh, slices through the soul.

No matter if you are a mortal or a self-proclaimed god. As long as you have a soul, this sword will kill you if it cuts through it. I have yet to meet somebody who survives without a soul.

But just like any weapon, even this one had a downside. It could only manage a single attack. Soul-Slicer's attack can only be used once and then the seals on the weapon burned out from the sheer power the sword produced, leaving a useless sword behind.

In conclusion; it was a Joker weapon. That didn't matter since I was alive next to the lifeless body of Jack Uchiha.

"Tremble before the power of my first Fuinjutsu weapon. And I am not even at my strongest."

I whispered before a grin formed on my face and I fell on my back and a laugh escaped my lips that grew louder and louder.

"Ha… haha…AHAHAHAHA!"

The battle was over and I emerged victorious.

General POV

With the battle won, there were mixed feelings floating around the battlefield. Those that did not participate in the fight were relieved for it to be over. A few pinched each other to see if this was a dream or not, only to feel pain and realize this was truly real.

Yet those that fought and felt the power of the enemy still had a hard time comprehending the absurdness that happened.

Wasn't it usually a hard battle where the good side had to be first put down only for them to show their hidden power and defeat the evil villain?

If so, then why did Jack, a name feared by everyone who knew him, laid motionlessly on the ground next to the laughing human who was barely 2 weeks here?

Some just gave up questioning the impossible and just went with the flow like four of the Furious Five.

Shifu, on the other hand, couldn't believe what he saw. His mouth opened and closed several times, but no sound came out.

Tigress was also stunned, but she was amazed at the display.

She had pride in her strength and enjoyed a hard-fought battle.

Tigress fought Jack on a few occasions and knew his power. That's why she urged Ishizu to leave to save his life.

She also fought Ishizu and therefore could compare their strength, and even though she lost to the latter, in an unworthy way, she could definitely say that Ishizu would lose in a fight against Jack.

Yet here the unimaginable happened and there wasn't even a battle! Not only that, but Jack didn't even have a wounds while Ishizu had some superficial one. None would leave battle scars to remember this epic fight.

How? How was this possible?

Shifu, too, had a hard time comprehending the situation, yet feeling a familiar presence and turning his head, he just rolled his eyes and gave up questioning the impossible, for another impossibility was here.

He saw a panda defy the odds by becoming the Dragon Warrior, finding inner peace, and saving them from Kai, so why should he question something like this?

"So… did my apprentice impress you?" Po spoke proudly as he glanced at Oogway, who chucked.

He, too, like everyone else, was shocked to see such an outcome. The turtle could just hide his emotions and, therefore, looked calm and relaxed.

"Yes, he did indeed. A student worthy of the Dragon Warrior."

An explosion occurred, causing them to freeze, fearing Jack would come back but instead they felt their Chi returning.

"Oh?! So that's why I had a hard time circulating my Chi. Ishizu blocked it by using a seal crafted with Fuinjutsu. That's why he asked me to give him the box. To come up with something like this in such a short time. Wonderful, he impresses me every time I see him," laughed Po with Oogway smiling.

"Yes, he is similar to you, Po. Defying the odds and expectations of those surrounding him."

But those were not the only ones that had thoughts about the outcome of the battle between Jack and Ishizu.

Deep inside Ishizu's soul, a certain Otsutsuki nibbled on her fingers, clearly in frustration.

'He did it. Not only did he come back to life but he actually did it!' Yamai screamed inside her head as she watched the outcome.

She, like her sister and the rest of the Otsutsuki, would often find life on other planets, but their clan's power would overwhelm everyone.

The same should have happened here. Using Chi, Jack's power rivaled an upper main member of an Otsutsuki, so Yamai was amused when Ishizu cut off the supply of Chi to even the power, but even without Chi, Jack was still too powerful for Ishizu.

Being inside Ishizu, she could gather some information about the EMS, learning it to be a diluted version of the Rinnegan, but with its own powers.

Even with his Rinnegan, Ishizu should have had a long battle, taking hours or even days to settle, yet the battle lasted not even an hour.

Otsutsuki members rarely felt fear since they were on top of the food chain, but seeing Ishizu slice somebody's soul in half made her rethink how to speak next time with him.

One thing was certain.

She definitely approved of Ishizu Sasaki marrying her sister Kaguya Otsutsuki.

Ishizu POV

The fight was over and everyone was helping each other to rebuild what was damaged.

I, for one, sat next to Jack's body and examined it.

In terms of strength, Jack would be the #1 Shinobi I have fought in my life.

How many years has he lived here to not only learn the language but also have such mastery over Chi?

I won't say I would have lost without Soul-Slicer since this would be a hit to my pride, but it damm well cut the time I had to fight.

Thought I would have surely lost if I fought a Chi-enhanced Jack. No need denying the obvious. I didn't have decades or so to learn a completely new energy.

A thought came up in my brain.

'If Jack fought Madara, who would win?'

Jack is dead. If only I could use him for my goals… oh never mind, I forgot I have the Edo Tensei. Even if I cut his soul in half, it should still reform in the afterlife and technically could be brought back.

On the other hand, Jack only showed a small amount of his power. Not once did he use his Sharingan powers, each hidden in the one and the other eye. Just his Susanoo was enough to make me pull out my Soul-Slicer and blitz him.

I'll have to tinker with the seal so he won't go on a rampage in an undead body. The Elemental Nations would cease to exist. Also, how would Chi react with him? Could he even use it?

So maybe he could go toe to toe with Hashirama era Madara but the Chi-empowered one could do so with Six Paths Madara for sure. I won't let something like that out without making sure he couldn't betray me.

"Eh, who knows? The future is still undecided. Let's focus on the present and take the spoils of war," I carefully wrapped his body around with bandages and took him with me to Po, whom I saw just a moment having a friendly chat with the rest.

By friendly, I mean Po rubbing the back of his head with his paw while a certain tiger was speaking to him with a serious expression.

"Can I go home now? I have like no idea how long I was gone and I still have to stop a war and revive Kaguya."

"You!" Tigress turned towards me and dangerously pointed her finger at me.

"Me?" I replied, pouting my finger at myself. She was really looking like a volcano ready to burst. I would have my fun with her a bit more.

"You!"

"Me!"

"You!"

…ok that's enough. Even I can't go on anymore.

"Why are you looking so angry? You guys do that whole "Inner Peace" thing, so where is yours or are you saying you aren't a Kung Fu Master?"

I knew it was a bad idea to provoke the tiger in the room, but hey give me a break. I just had 2 weeks of training and learning to defeat a crazy Uchiha, so if she presents herself so open I sure will take the chance.

"ARGH! You are worse than Po," she stomped on the ground, breaking it a bit.

She sure was holding herself back to lung at me, going by the twitching of her paws and left eye.

"Let him be, Tigress," Po tried to calm her down, only for me to laugh inwards, seeing as her anger redirected itself towards the panda.

"Yours! It isn't his fault, but yours. He claimed to be your student. To have such…"

Here Tigress blushed before her demeanor changed back to anger. Wonder what she was thinking?

"You should be ashamed to have trained your student to be so perverted and unpredictable."

Her sentence confused both Po and me. What the hell did she mean?

"I do understand that he defeated Jack with a hidden ace under his sleeves, but I don't get the pervert part," Po shook his head.

Oh, I certainly got that part. She was talking about the seals I used against her.

"By that, she means how I won the fight between us by basically making her go into heat."

Honestly, I shouldn't have said that. Knowing how prideful Tigress was and telling one of her best friends about such a topic was a horrible idea.

No wonder she lunged at me after that comment. I braced myself for a beating I didn't have the strength to prevent, but really deserved.
