T7MS - Team 7's Mystery Shop, yep, that sure DOES sound like a cuss word to me!
Story Start!

A dud.

The Ninjutsu that was suppose to bring an end to the Infinite Tsukuyomi was a dud, meaning the Six Paths Sage had been completely wrong about how to end the jutsu. The technique that Madara Uchiha had used the moon to cast had affected the entire world, all intelligent and unintelligent life that wasn't plant life. All life forms were currently all wrapped up in plant tentacles and strapped to the great tree branches that were circling all over the entire planet.

*BOOM*

"Destroying the moon didn't end it either." Naruto said as he looked up at the sky, with his arm raised since he just threw the technique that he used to destroy the moon in the sky. Everyone looked around (Sakura and Sasuke) hoping that would have ended the technique manually, but to no avail. "Sasuke, explain." Naruto looked towards Sasuke, powering down from his Six Paths Sage Mode with a frown.

"The Moon isn't powering the technique, it was the catalyst for it. The Infinite Tsukuyomi uses the moon as a light source to cast the Genjutsu over the entire planet. That was why I was able to save you from it, by using a Susanoo with my chakra to block the light while it shined at it's brightest." Sasuke explained that destroying the moon had been a pointless action. He didn't object to it, because all ideas were on the table. He certainly didn't have the power to do anything about it.

Unlike Naruto, who had recovered over a third of his chakra in the few hours since their final battle, he was still running on what was pretty much fumes at this point.

Sakura glanced at them sadly.

"Out of everything... this is why we fail?" Sakura couldn't help but look at their missing arms.

Naruto missing his right arm, and Sasuke missing his left arm.

Naruto ended the 4th Great Shinobi War, found countless reincarnated shinobi and white zetsu, saved the lives of countless ninja. He fought for 3 days and nights straight, without so much as a lick of food, water, or sleep, all for their sake. He had defeated so many powerful opponents, and even converted some of them to their side at the end. Kaguya, the Alien Rabbit Goddess, had been sealed away forever in her Genesis Dimension. Naruto had befriended the Tailed Beasts, who had already wondered away to where their homes were. Naruto ahd fought and finally gotten Sasuke back for them, their team complete again.

Team 7 was complete again... in a world with no other people.

"Kaguya is sealed, if this was like any normal technique, it sounded have ended... the Infinite Tsukuyomi truly is the ultimate genjutsu..." Kakashi noted with an angry sigh, even he was angry over what had happened. They had gone through so much, but it was because they simply weren't able to end the technique that they had failed.

That was bullshit!

Sasuke made no comment, he just started to go over his new Rinnegan abilities in his head, including the abilities that he had yet to make use of. With his Rinnegan, he had been able to do so much, and he had other abilities he hadn't gotten the chance to use. He had the knowledge of these abilities, but he just physically didn't have the chakra to be able to make any use of the ability to create portals to other dimensions. Yes, he knew of this ability, even if at his full power, he lacked the chakra enough to open the portal itself.

The ability to open portals to other dimensions?

"Naruto, I need chakra... I need more than double my chakra mount." Sasuke gave out an order to Naruto.

"Say please-

"Do it." Sasuke stopped Naruto from trying to lighten the mood, something he was usually really good at, but Naruto's heart just wasn't in it right now either. He had just made that joke out of instinct, but Naruto placed his hand on Sasuke's shoulder, and completely refilled his chakra and then some, pushing him over double his reserves.

Kakashi glanced at Sasuke with a raised eyebrow when he felt Sasuke begin to mold the chakra he was given, and focus it around his Rinnegan eye.

"Maybe the jutsu failed because you two don't have enough chakra to do it." Sakura spoke, so maybe they just needed to wait for them to both fully recharge.

"The jutsu uses Sasuke's Rinnegan, and my chakra that is fused to the Tailed Beast chakra... but it takes so little chakra that isn't the issue. The Super Gramps said he researched the Infinite Tsukuyomi... but even he didn't know for sure if this world would... damnit!" Naruto slammed his fist into a boulder next to him, shattering it with his strength, gritting his teeth as hard as he could.

Kakashi just kept looking at Sasuke.

"What are you doing?" Kakashi asked Sasuke, but was completely ignored.

"Hey bastard, what are you doing?" Naruto asked instead this time.

"Kaguya created over 5 dimensions, but she herself is from a different dimension too. That means there are entire dimensions out there with life out there. One of my abilities is to open portals to other dimensions... but my ability to sense things in far away dimensions is... Naruto, Six Paths Sage Mode." Sasuke looked to the person with the best sensing ability out of all of them, Naruto, the person who was able to sense things across Kaguya's dimensions, and sense Madara's Limbo clones that existed on a higher plane of existence than theirs was.

If dimensions with life existed out there, Naruto would be able to sense it if he put his mind to it.

"Right!" Naruto had a hopeful smile on his face as he powered up to his Six Paths Sage Mode once more, and he started to sense around for anything with a powerful enough energy for him to locate. "... I sense a few chakras like Kaguya that way-" Naruto gestured to a weird up and down direction, before he looked to the right. "... but they feel bad. Over there though, I sense a couple of weaker energies that aren't chakra... when I sense those energies, I'm getting the image of a big dragon and a little girl... neither of them are threats though." Naruto gestured to the left/right dimension.

Sakura and Kakashi were lost, they did not understand what Naruto was gesturing to, but to be fair, Sasuke seemed to understand. He looked to the west, and focused with his eye.

"We're going to go to other dimensions and ask for help?" Kakashi questioned Sasuke when he realized what he was planning.

...

"The Infinite Tsukuyomi only had a single method to end it, otherwise it is the perfect technique, an Infinite Genjutsu for a reason. This world is dying, there is nothing here for us anymore." Sasuke looked at Naruto when he said that. Kakashi and Sakura would see reason, he could even see it on their faces that they understood what he was getting at right away. "Soon enough, in hours... days... weeks, everyone trapped in their happy dreams will be converted into White Zetsu... monsters." Sasuke stared Naruto right in the eyes when he said that.

Even if it were possible somebody in another dimension could end the technique, more than likely, when the technique was ended there would still be nothing worth saving remaining.

Sakura and Kakashi looked towards Naruto, who was now visibly against this plan.

He still wanted to save everyone.

"We should give up on them... we need to save them, they are our friends, family, comrades... people we also don't know, but worth saving anyway." Naruto glared down all three of them. He took turns with each, glaring down anyone who looked like they were all for what was happening.

"Naruto, they're right. You're not this foolish, you can sense that in a few more hours, everyone trapped in the Infinite Tsukuyomi will be done converting." The biggest voice inside of his head spoke to him, Kurama, telling him what he already knew. Something he was aware of, but didn't want to consider.

Naruto's face showed it though, his so easy to read face.

"It's hours, isn't it?" Sakura could read his face better than anyone other than Sasuke, and she could see that by it, their time limit for saving everyone was just a few hours.

...

"It would be merciful for us to just leave this dimension... and for you to destroy this planet. If there are other people like Kaguya, they might use everyone as an army. This isn't killing our comrades, this is a mercy killing." Kakashi knew Naruto and Sasuke could each pull off this feat, but only Naruto woudl be able to do it easily, since Sasuke just used up over half of his chakra to open the portal to another dimension.

"We can't leave the Tailed Beasts behind, or destroy the planet with them on it!" Naruto argued against that too.

That was something they couldn't do.

"The other Tailed Beasts will just respawn wherever their chakra is given enough time, and since you have all their chakra, they will respawn in whatever dimension you are in. I've already asked the pieces of their chakra in you, and they agree to being killed for now." Kurama informed Naruto he was wrong there. Naruto's gripped fist was shaking horribly, because everyone was just giving him reasons why what they were doing would be okay.

Mercy killing one person was fine, kind of, when it was needed.

They were asking him to commit mass genocide against all species, their own species included, and destroy their home planet. They were asking him to shoulder billions of lives on his shoulders, to mercy kill an entire world.

"I'm going to harvest some of Hashirama's cells from Madara before we go, so hopefully I can rebuild you two new arms with them." Sakura sighed and went over to Madara's corpse, using a chakra scalpel to cut off a chunk of Hashirama's flesh from his chest. She took a scroll out, and sealed away the flesh. "Naruto... we failed, the least we can do it stop everyone from becoming monsters... they won't feel any pain. The roots of the Shinju have scattered over the entire planet... the world will be drained of it's natural resources in weeks. We can't save our world anymore." Sakura explained to him as she gestured to the thousands, billions actually, of roots that were all over the world now.

They failed.

Naruto was silent.

"Just go through the damn portal... I'll do it, but I don't want anyone watching." Naruto told them bitterly, his voice filled with anger.

Nobody argued, he had the right to be angry, so Kakashi put a hand on Naruto's shoulder to comfort him, before he walked through the portal. Sakura hugged Naruto tightly, wordlessly, and she walked through after Kakashi. Sasuke closed the portal behind her, and nodded his head to Naruto.

"You won't be able to do this alone."

"I'm more than strong enough-"

"Your heart isn't strong enough to do this alone." Sasuke corrected himself as he stared into Naruto's eyes. He knew Naruto could do this easily, but there was no way that Naruto could make himself do this without support. He just didn't have the heart of somebody ruthless enough to destroy a world, it wasn't in his good nature to do it. Sasuke actually smiled when he saw Naruto send him an appreciative smile.

Naruto powered up, and created a chakra arm to grab onto Sasuke.

In a flash, Naruto flew them so high into the sky, they were able to see the dying planet down below. He opened the palm of his chakra arm, and Sasuke stood in it, as the two of them looked down at their world from the heavens above. They had a few moments of peace, not seeing a dying world, but instead a beautiful one.

"I'm not crying."

Naruto had tears streaming down his face, Sasuke didn't even have to look at Naruto to see that he was crying tears of regret. He gave Naruto the respect of not looking at his face to confirm it though. He felt a shift as Naruto lifted his arm into the air, and a Tailed Beast Ball Rasenshuriken formed instantly above it, a very small looking attack, before he threw it down at the planet without mercy. With massive speed, it across the distance between the heavens and the planet in no time at all, before the white explosion could be see covering a large visible portion of the world. The world started to crack as the explosion pushed it's way into the planets core, before the pressure started to build up with lava spewing from the massive cracks.

The planet exploded.

Naruto raised his hand again, and this time 6 large Tailed Beast Ball Rasenshurikens formed above his head, and he threw them down at the rubble of the planet. Like nothing, even the planet's rubble and leftovers were destroyed, Naruto making sure that there was nothing remaining of their world. Sasuke didn't look at Naruto though, they just floated there for a few more minutes as Naruto calmed himself down, wiping his eyes.

Naruto was a good person... asking him to do this had been wrong of them, but it needed to be done, and Naruto knew this too.

"Lets go." Naruto spoke as he slapped his cheek.

Sasuke nodded and opened the portal.

Time to make a new home.

Chapter End!
