Rias was unsure.

Naruto gave her 30 minutes to come up with a plan, before they would go out into the forest alone without alerting anyone to the fact that they would be disappearing. She watched as he walked with his arms crossed in front of her.

"... Usually, we would spend a few days looking for-"

"I gave you 30 minutes to prepare yourself Rias, because every second we waste is a second the others could be targetted. The more I thought about it, the more I realized this needs to be taken care of as soon as possible." Naruto stated to her, and interrupted her. The longer they waited, the stronger the enemy would become. "Right now, the enemy is as strong, or even stronger, than Sairaorg is with his Balance Breaker. Can't you sense that?" Naruto asked Rias with a raised eyebrow.

She looked down, before she nodded her head.

Even she could sense the absolute strength inside of the forest, the dark and hateful power that existed. Rias looked at Naruto, and she saw him take his yo-yo out and hold it firmly in his hand.

It changed shape.

"That is why we are going to end this tonight while the number of victims will only be 1 person." Naruto stated to her coldly. He gripped Excalibur in one hand, and he glanced towards her as she stared at the sword with knowledge.

The aura of the sword alone made her skin tingle and take damage.

"We need to take Tsubasa-"

"Tsubasa is going to die tonight, I'm not going to try and keep her alive." Naruto stated to Rias with a sharp tone. Rias' eyes widened in shock, and her warm blue eyes came in contact with Naruto's eyes. She saw nothing but determination and drive in them, a white hot emotion in them, hidden underneath the cool blue. "Don't be an idiot, I'm going to kill her painlessly. She didn't pick this path, the least I can do is make sure she doesn't suffer." Naruto's compassion held up.

Rias gripped her fists tight, before she unclenched them.

"... Yeah... I understand."

"This sword is the only Holy sword that was not forged by God. This sword was forged by the planet itself. This sword is the wishes of humanity itself, stored and tempered in the core of the Earth. It is the crystalization of the prayer called glory, all warriors know this blade and feel... by holding this blade in it's true form, I'm sure that our target will be attracted to it like a beacon." Naruto stated as he held the sword up above his head.

Rias looked at it.

"Excalibur was split into 7 swords-"

"This is the original, I can assure you. Anyway, I need you to be my backup. Stay back, and use your magic to watch my back. Will you be able to do that?" Naruto asked her without looking at her at all. He just needed to know if he could put his faith in her, and that was all he needed from her.

Confirmation.

"Ye-"

"Know that you WILL be assisting me in killing Tsubasa tonight, your friend's servant!" Naruto stated to her loudly.

"Yes, I will watch your back!" Rias gave him the confirmation that he needed.

-Fate/Grand Order Ost: Wind of Karma-

"UZUMAKI!"

Naruto smiled when Rias was shocked, Tsubasa's demented voice shouting out as she came flying at them from the air. Rias was shocked to see the changes that Tsubasa had gone though, almost nothing but the base looks of the previous girl inside of her was left. All that remained in her eyes was a desire to kill, and her skin was darkened to match.

"EXCALIBUR!" Naruto shouted as he swung his sword down.

Naruto wasted zero time in unleashing his strongest attack, and he aimed it right at Tsubasa. Naruto was willing to completely obliterate Tsubasa if needed be. The wave of flaming light he sent out destroyed everything in the general direction that he fired it in, and he turned over half of the forest itself into a crater with his first attack of the fight.

A strong holy power appeared in front of them.

"Excalibur MORGAN!"

"... I see, so that is who our opponent is." Naruto stated as black light erupted out of his golden light and cancelled it out halfway through it's destruction. Naruto frowned to himself when he saw that Tsubasa was still alive, but she was standing in the middle of the crater holding a black and red version of the sword in his own hands. "Rias, stand back further and charge up your magic. Our opponent isn't Tsubasa, prepare to kill Tsubasa when I give the order. Your one attack will be the difference between victory and loss." Naruto stated to her.

Excalibur Morgan?

There should only be 1 Excalibur, but if there existed a second Excalibur, a blackened Excalibur, then Tsubasa could have only gotten an Evil Holy Sword from a single possible place. A place that she had absolutely no access to on her own.

The planet Earth itself had forged Excalibur Morgan and given it to Tsubasa.

"Uzumaki!"

"Start charging Rias-" Naruto rushed forward with one massive leap into the crater. He was already mid-swing and his blade clashed with Tsubasa's blade. He made eye contact with her, and he could see a lack of intelligence in her gaze. "-because it seems the planet is going to give it her all to kill me." Naruto punched Tsubasa in the face.

His fist was part of his body, and he only needed one hand to hold a sword, and while he needed both hands to fully unleash Excalibur's power, right now he needed versatility more than raw power.

'Gotta keep it up then.' Rias thought to herself as she put her hands close together, and began to charge her magic up between them. She needed to gather as much of her inner power as quickly as possible.

Naruto grinned.

He saw 2 swords coming at him, even though he could only see a single sword. Naruto blocked the sword that he saw, before he jumped backwards the second he felt the second blade pierce his skin. A light cut appeared over his stomach, and Tsubasa pressed her advantage and rushed forward in the same stance.

No, she changed stances.

"I see... of course, the planet that has recorded all of human history, can give a warrior knowledge of all human weapon styles." Naruto saw the rapid change in style. The first attack had started off with an unknown style, and once he escaped it the style changed into La Verdadera Destreza.

Naruto kicked his foot into the ground, before he ducked under her sword. He ripped his foot out of the ground, and with it he smashed a boulder towards Tsubasa's body. She destroyed it by attacking it with the flat of her blade.

She switched back to the style he didn't know, and she unleashed three attacks similar to the first one that she unleashed.

"Die Uzumaki!"

'Damn, this is a scary attack, I can see my head flying from it... but I'm starting to understand it.' Naruto thought to himself as he defended himself only against the attack that would have cut his head off. He took a cut to his ribs and belly again, and avoided fatal wounds by stepping backwards.

The strongest swordsmen technique was a technique even he didn't recognize, and it seemed Tsubasa was pissed that he had survived it again.

"Impossible, you survived twice?"

"Oh? Yeah, but do the same attack, I've seen it twice now... I've about got it figured out. You aren't swinging your sword three times, are you? Tell me, what swordsman created this technique you've stolen?" Naruto asked with a grin. He readied himself for the attack to come a third time. He sensed no magic from the attacks at all, nor was any mystic forces being put to play.

Tsubasa rushed towards him.

All three attacks were launched at the same time, perfectly the same time. It was a physical impossibility that the three attacks could be launched at the exact same time with no delay between them. On his third time seeing it though, Naruto was able to see with his own eyes what was happening.

Naruto ripped one of his ribs out as he jumped into the air.

With Excalibur he blocked one blade, with his ripped out rib he blocked another sword, and he jumped over the third sword while blocking the two blades. With both of his feet Naruto kicked Tsubasa in the middle of the chest. He sent her flying with blood coming from her nose and mouth, the dual kick a normally instantly fatal attack when done by somebody with his level of strength.

"Naruto!"

"Gather magic Rias, this much is nothing! One or two ribs can be put back and healed later! My attack isn't strong enough to finish her, KEEP charging!" Naruto ordered Rias. He had a large hole in his side from where he ripped his rib out, but the bleeding wouldn't be enough to slow him down much.

A black energy beam shot towards Naruto, and he swung his sword upwards when it got the perfect distance from him. With his own sword beam, he redirected her attack towards the sky so that their combined attacks destroyed the clouds. A second beam came, followed by a third and a fourth.

She wanted to unleash a barrage of attacks at him, and try to exhaust him as he was forced to redirect all of the attacks. He wasn't able to counter attack, because the non-stop barrage of beam attacks was taking all of his attention.

"I've gathered as much as I can safely-"

"Gather MORE than that, that level of power won't even scratch her!" Naruto shouted as he redirected seven more attacks into the air. They started to come at him faster and with more force between them.

Tsubasa had black energy from the planet shooting from her surroundings and into her body, giving her more power to amplify what she was using. She could see that Naruto was defending his surroundings and Kuoh behind him, while also protecting Rias while she charged energy. She could attack endlessly using the energy of the planet, but Naruto had to defend against her while protecting everyone in the city behind him.

The Uzumaki would die.

"Huh?" Tsubasa asked with shock.

Excalibur was 2 inches from her face.

Naruto threw Excalibur at her while he had been redirecting attacks, and to avoid getting her head cut off by the thrown sword she dodged and cancelled her next attack. She watched as the sword stabbed into the ground behind her.

"Naruto-"

-Fate Grand Order Ost: Absolute Demonic Front-

"Come on Earth, or Gaia, or whatever you want me to call you! My weapon that you should be afraid of isn't Excalibur, instead of creating Excalibur Morgan to fight me, you should have created a way to counter THIS!"

*CRUNCH*

Naruto's fist smashed so hard into Tsubasa's face that the air around them distorted, and the crater they were standing in got even deeper in the ground around them.

"Even more than Excalibur, it's my body, my fists, and my burning human soul that you should have created a counter to! You might have ALL of human history's past in your hands, but unlike you, I have the past AND the FUTURE packed into these fists!" Naruto grinned as he lectured the planet itself. Naruto slammed his foot down on Tsubasa's foot to stop her from being sent flying by his fist.

She swung her sword at him.

"You've lost-"

"Rias NOW!" Naruto gave the order. "Aim your attack at us, full power!" Naruto demanded as Excalibur Morgan pierced his shoulder and started to cleave through his flesh. The sword stopped when Naruto flexed his shoulder and caught the blade using his muscle fibers and his bone.

Rias was stunned.

Naruto punched Tsubasa in the face a second time, and she responded by punching him where he had ripped his own rib out. Rias watched as Tsubasa was forced to abandon her sword completely in favor of being forced to challenge Naruto to a fist fight.

"You, the last Uzumaki, will die!" Tsubasa raised her hand up, and forced a shadow snake and gripped it in her fist. Her fist was cloaked in the snake shaped energy, and in her other hand she formed a energy cloak in the shape of a rooster.

Naruto took one of the attacks to the chest, and the other attack to the chin.

Tsubasa was punched in the center of her chest, and all of her ribs broke.

"Compress it further... aim to only hit Tsubasa..." Rias started to compress all of the magic that she had gathered into as small of a ball as she could.

She was pushed back when fist met fist.

She gasped when she saw Naruto smiling.

"Cut my arms off, and I'll kick you to death!" Naruto shouted as he kicked Tsubasa in the hip while still using his other leg to keep her attached to the ground. Naruto lifted his other foot off the ground and allowed Tsubasa to escape his grasp. Before she could escape though, Naruto sank his teeth into her armor. "Cut off my legs and I'll bite you to death!" Naruto shattered the armor she wore with nothing but his teeth.

Tsubasa looked at him in shock.

She looked him in the eyes.

'He's... having fun right now?' Rias didn't know how she should think.

"If you cut off my head, I'll glare you dead." Naruto's fierce gaze got Tsubasa to back away, before more enery from the planet entered her body and her wounds healed slightly. She got more powerful than before. "Just know, that you will never kill me, because I'm going to beat you. Keep sending corrupt warriors after me, and none will ever kill me. I don't even care why, because I am Uzumaki Naruto... and I am this planet's KING."

Rias saw Naruto grab Tsubasa by the shoulders.

She launched her attack, a small ball of the Power of Destruction that was all of her magic condensed into a ball the size of a yen coin. She launched it when she saw Naruto glance back at her, and she knew exactly what she needed to do.

Her attack pierced right through Naruto's back, came out of the front of the right side of his chest, and then pierced right through Tsubasa's heart.

"Yo-you... cheated... Uzumaki... don't... I made sure... I m-" Tsubasa collapsed on her back as her body started to return to normal. The light left her eyes as she was laid to rest in a pool of her own blood.

"... Ow..."

Naruto had a yen sized hole in his chest, going right through his lung. Yeah, that was what he had intended for Rias to do once he was able to line Tsubasa up for a shot. He didn't have the physical strength to actually do any fatal damage to Tsubasa, so he needed her magic to unleash the shot himself. Her Excalibur Morgan was a Holy Sword capable of cancelling out his Excalibur.

"I'm so sorry!"

"It's fine Rias, it will heal. This is why I like to take care of these things as soon as possible. Sometimes, when you give your enemies time, they just gather their forces. I like to stop small problems before they become big problems." Naruto still didn't know exactly why the planet wanted him dead, since clearly Tsubasa had targetted him during the fight, but that didn't really matter. "I can survive with one good lung until I get to Asia and she heals me... and helps me put my rib back in my chest." Naruto looked at his bloody rib on the ground.

That was going to suck to put back in, it might suck even more than when he ripped it out. Naruto reached up and grabbed Excalibur Morgan that was in his shoulder.

"By the way, don't tell Kiba you have Excalibur-"

"Didn't plan on it, anyway, would you stop being an idiot already?" Naruto asked Rias as he turned Excalibur Morgan into a yo-yo and put it in his pocket. He walked over to where Excalibur was stuck in the ground, and he pulled it from the dirt and turned it into a yo-yo as well. He put both the Evil Holy Sword and the Holy Sword in his pockets, before he walked over and grabbed his rib from the ground.

Naruto saw Tsubasa twitch, so he kicked her in the head.

*SNAP*

He broke her neck for good measure.

"Not dealing with that again." Naruto saw all of the life leave her eyes. Naruto used his free hand to pick up Tsubasa from the ground and tossed the corpse over his shoulder. "Now come on Rias, and stop being an idiot." Naruto stated to her with a deadpan tone.

Naruto looked at the dirt.

"Eh? Tsubasa is dead now... how am I still an idiot?" Rias asked as she looked away from what used to be the servant of one of her best friends. How was she going to tell Sona that she had been a part of the reason that Tsubasa died?

Sure, she turned super evil and all, but she still pretty much killed her.

"We killed her quickly and painlessly you idiot, and she doesn't have her Rook piece in her anymore. She died a human."

"What does that..." Rias stopped herself when she put two and two together. Her eyes widened, and she looked at Naruto with her jaw dropping. "SONA can revive her!" Rias palmed the side of her head.

She forgot.

Tsubasa had been turned back to human before she died, meaning that she could be brought back to life by the Evil Piece again. She had forgotten the part about Tsubasa turning human, or rather she remembered but she still considered the girl to be a devil under Sona in her heart. Now that Tsubasa was dead, the corruption had left her body and she could be brought back to life.

"You hear that planet Earth? Corrupt as many people as you want, but they will all just die and be brought back. Don't even bother trying again, the outcome will just be the same as this." Naruto threatened the planet.

He knew the planet could hear him.

"... You're taunting the entire planet?" Rias deadpanned at him for once, her arms crossing under her chest.

Naruto raised an eyebrow.

"I plan to become King of the entire planet, so I'm just letting the world know I'm boss now. Anyway, I'm going to die from bloodloss if we don't hurry up. You take Tsubasa back to Sona, I'm going to go-" Naruto forcefully shoved his rib back into his body and rearranged it so that it was about in the right spot for it to be healed. When Asia healed it, the magic would fix it right up anyway, but the rib did need to be in his body for it to work out properly.

Naruto closed his eyes and sucked in his breath.

That hurt.

A lot.

Chapter End!
Please Leave Me Lots of Nice Long Reviews, But No Flames Please!

Yes, the theme of "Absolute Demonic Front" will be the Naruto's battle theme for when he is honestly going to give it his all during a fight. I thought it would be most theme fitting.
