The Beginning of The End

-XXX-

Seven hours ago Jaune and his team as well as team RWBY had been called in and were asked assistance of the two teams. He accepted readily... but why did that decision sound wrong? Maybe it was how the other occupants in the room looked.

He shrugged it off as just them getting psyched for the mission. But, then why did Ozpin and Glynda look the same?

His mind flared with worry until he felt Pyrrha's hand on his shoulder... and a forced smile on her face...? Now he knew that something was wrong, and that he wasn't privy to it. But, this was his team and friends and he trusted them with his life.

How wrong he was to do such a thing.

It happened so quick that he couldn't even understand how he missed it - how his friends missed it, oh, they didn't. It was they all along. After he arrived on the battlefield, something felt wrong (Four years on a team with Pyrrha, Nora, and Ren, being friends for all that time he could internally sense something was wrong.)

He noticed that the others were oddly fighting as if they hadn't meant it - it was weird. He also noticed that more and more of them were leading the Grimm away from him - no that wasnt right they were running away? He shook his head of such thoughts, as they were his friends, friends that would never abandon him, right?

But, as evidence there was Pyrrha's spear Milo sticking out of his left-shoulder, his eyes widened as his mind and mouth were unable to form anything... Then he felt a bullet tore open his right-shoulder. He shook his head as he thought he was just imagining it but there Machines stood in place of the Grimm?

Turning around he saw that the place they were fighting in was Emerald Forest, but how? The mission sent them far south of Vale than where Emerald Forest was, but here the red trees stood. In addition, there stood his team - friends, countless other people he did not know.

Shocking of all had to be Headmaster Ozpin, Glynda and the other teachers standing there. All looking at him with... shame? Guilt? Were they regretting doing this to him? Suddenly his face met the ground in a loud thud. He gasped in shock, and screamed in pain when a hand was shoved into his backside.

It freaking hurt!

Was the only thought Jaune could think of as he suddenly realized what THEY were after, what he as the weakest brother would never expect to have inside him. He knew that if it fell into the wrong hands it would 'cause destruction, even in the hands of someone good. He would never experience an incident like ten years ago!

Reverse gripping Crocea Mors he swung at the person on top of him, the person evading with grace and speed. The person he was swinging at was Weiss?! He saw how her eyes widened as a new scar was now on her right-cheek.

He wanted to feel guilt at what she had done, but the thing inside him took precedent at this moment. He took out Milo and threw it at the ground. He also noticed that the Atlesian soldiers who had stood behind the teachers started to draw their weapons.

"The only way I would be revealed was if my father and sisters had a hand in this. Where are they?"

No one said a thing.

Suddenly a vortex of pure wind picked him up and was literally now thrashing him in the air. He fell to the ground with sickening crunch that could be heard by everyone.

Yup, Jaune's left arm was now officially broken.

When Jaune stood up again he saw Team CREM (Cremation) there, with the leader Cinder Fall's eyes glowing in a orange colour? There stood Mercury, Emerald, and Rika Neopolitian.

And was he imagining it but was it magic he was sensing?

He stood up with one broken arm and knew that he had to get out of here - away from them who sought to use what was inside him. So, he turned and ran. He pushed his body for as long as it could... but alas all things come to an end.

His chest was pierced by a block of solid ice, the only thing keeping him alive inside him, slowly leaking magical power. He stood up with the ice in his chest.

Only a few more steps! Once I get to that cliff I can get away.

Gritting his teeth as he limped the last few steps, he was stopped as his feet was frozen in place. Looking down it was engulfed in ice. When he saw Weiss Schnee walk infront of him he could see the Guilt coating her face. Her pale white hand reaching into his chest.

He resisted giving up the thing that changed his life ten-years ago.

"My family is dead, right?"

Weiss nodded her head.

Tears fell from his eyes.

All he could do was try to convince them that this would only bring chaos and destruction.

"Stop this! You all have no idea what is gonna happen when this thing's seal is released! The World you all know will fundamentally change."

A small voice in his head wanted them to experience what he went through.

'Let them feel it.'

'Let the Chaos engulf their entire being.'

'Let them feel the Despair you felt.'

They ignored it, and now there stood Ozpin holding the cursed chalice.

He would never know if what he did was out of fear to tell them what he went through, or if he wanted to let them feel the pain. But, he was a hero of Justice just like his older brother...

"This grail will only bring Destruction and Anguish. I was there, I know. This thing will be the end of all Mankind! Please... I am utterly and truly begging you all to stop this..."

"I am sorry Mr. Arc but if there is a chance to eliminate the Grimm it's worth it." Ozpin spoke, his hands clenched unto his cane and a serious expression on his face.

...

At first Jaune looked at the Heavens as if he heard something, suddenly he started to yell, "A-Alaya? I-I accept! I give my soul and body willingly! I WILL BECOME YOUR COUNTER-GUARDIAN!" Jaune screamed, as tears fell from his eyes.

-THEN HEREBY JAUNE EMIYA I ACCEPT YOUR WILL AND DETERMINATION.-

A Voice boomed from nowhere as everyone looked around and couldn't find it until a Blue Sphere materialized infront of Jaune Arc. All of a sudden, white strings started to attach to Jaune Arc, his severed hand as well.

Turning around Jaune glared at the people who stood there with that chalice of despair, intending to destroy the chalice he was being forcefully pulled back. Glancing back he saw the strings pulling him into a vortex of sorts.

"No! That thing has to be destroyed Alaya!"

...

"I-I can't Alaya... That thing has to be destroyed."

...

In that brief instant Jaune was shown various alternate realities where he saw that whatever he did, whatever he said would not matter, it would just lead to the same outcome...

Hell.

When Jaune looked back at the Grail and all the people he understood that what Alaya said was true, these people are too far gone to listen to reason. Was this how scared the Humans were of the Grimm?

But, he had far more pressing matters then one World. Alaya had made him a Counter-Guardian that was meant to protect all the Worlds. He was made for the purpose to stop Leff Lynor Flauros, the Demon God from destroying everything.

Jaune's body started to become enveloped in a light as his body started to dematerialize. Everyone saw as Jaune turned to dust and flew into a blue portal.

"This is the wrong choice..."

-MANKIND IS SAID TO LEARN THROUGH EXPERIENCE. THEREFORE, I WILL NOT INTERVENE IN THE SIXTH HOLY GRAIL WAR. I PRAY FOR YOU HUMANS."

/

Five Years Later

He had spent countless hours searching for the place where he knew it would begin again - and he found it. Currently Jaune, or now known as Archer was currently standing atop one of the various spires above Beacon Academy.

Down below him was various people, Faunus and Human alike all chatting with each other. He was currently tracking Leff Lynor Flauros the target the World assigned him. Suddenly a portal of blue light appeared behind Jaune as a boy and girl stepped through.

Glancing back, he saw Mash and Fujimura Ritsuka; his friends in his endeavour to stop whatever Leff was planning. Suddenly there was a commotion on the ground as Faunus and Humans ran to the front gate.

"What's up?" Fujimura asked, as Mash and Jaune started to focus on the front gate. Jaune with his eagle eye he could fundamentally see that it was more refugees. After the previous Holy Grail War the only thing that relatively still stood was Beacon, the Grimm destroyed all the other Kingdoms as the Grail War already had a massive impact on the world.

Jaune looked at the civilians, as they were rode in and somewhere in his heart a flutter of guilt coursed. This was his fault. If he just downright destroyed the Grail when he had the choice... Instead he followed Alaya's instructions. Nevertheless, if he didn't he would've never had saved the two standing behind him.

"What are we exactly doing here?" Mash asked, hefting her giant shield beside her. Jaune just simply looked at the entrance leading to the Auditorium and replied.

"All Alaya said was that something wrong was going on here. Let's go." Then all three jumped off the roof. Luckily, no one was on the ground who could see them. All except a raven staring at them from above.

/

While free falling Jaune had materialized different clothes for him, Mash, Fujimaru, and himself as means to blend in. The clothes that were created was finely detailed as it had dirt, blood and a few gashes on it.

He could create more than just swords so why waste that abilities he borrowed from his brother.

When Jaune, Mash, and Fujimaru arrived at the Auditorium many people were gathered around small makeshift beds, some lying on blankets handed out by Beacon staff and students. Jaune's teeth clenched as he saw the people who had betrayed him all those years ago - the people responsible for ruining this world.

A fear gripped him as well as rages until a hand was placed on his shoulder, looking back it was Fujimaru who looked at Jaune with a "No" clearly expressed on his features.

All of them had changed; far beyond, he could even remember... No! What was he saying?! They were the bad guys...

Quickly Jaune recovered from his anger as he saw how his former team and RWBY were handing out blankets and food rations. And then their eyes widened when they saw their target - Leff Lynor Flauros, there he stood talking to Ozpin.

It look like that Magical Dampener Romani made was working.

While Leff looked like any ordinary Human Jaune knew that he was a Demon, the one responsible for the Destruction of Gaia - Mash and Fujimaru's home world. And now here he was on Remnant, but for what? Jaune was broken out of his concentration as someone handed him a water bottle.

Following the hand to its face, his breath quickened, his eyes dilated and his body tensed. The feint feeling of a sword piercing through his chest was felt. He broke out into a cold sweat as he saw "Her". The emerald green eyes that gave him nightmares and the crimson red-hair that always flashed in the nightmares.

"Here." The crimson-haired woman said.

He couldn't even take the bottle if his life depended on it, focusing on the ground more than the beverage. Suddenly someone stepped infront of him - it was Fujimaru as he took the water bottle and explained something about why Jaune couldn't take the bottle.

Jaune sighed in relief as Pyrrha looked at him sadly before moving on. His legs gave out as he collapsed against the wall, all the while his breathing calmed down. He saw a flash of pink hair in his peripheral vision, looking up he saw Mash with a worried look on her face.

"Are you alright?" She asked, her hand on his own, and wait was it shaking, yeah it was shaking erratically. Fujimaru also appeared in his vision with a worried look and handed him the water.

"Here, drink." Fujimaru offered.

How strange the same bottle who that demon offered was now his rescuer? After a few minutes of drinking and breathing Jaune began to think more clearly. When he finally got his bearings behind him he stood up and offered a "Thanks" to both of them.

He noticed Team RWBY, NPR, and the various teachers along with Leff were missing. They probably went to the lower levels of this building he presumed. His Trace ability let him Trace almost anything, with buildings it showed what was used, what era it was built its integrity and level of floors.

It must be because of that, that Rin, Ilya, Sakura, Mash and Fujimarua always lost against him, all except his brother - EMIYA or now known as ARCHER V0.1 where as he was V0.2 as EMIYA could finally get his rest. After all, he was the youngest adoptive brother of Shirou Emiya, the other child who survived that HELL.

His true name once upon a time was Jaune Emiya, son to Kiritsugu Emiya, and like his brother, he also found his father's Ideal AWESOME! Yet, he couldn't follow it at that time... Being the vessel of the Holy Graii hadn't afforded him anything, infact it had made his life sheltered, whereas Shirou could follow his Hero of Justice Ideal, Jaune had been forced to be protected all his life.

Before the death of Kiritsugu he placed a magic on Jaune which would send the Grail away. It failed when Kotomine, alongside Leff activated it, bypassing the Magic, and starting the Fifth Holy Grail War. That's where Jaune bore witness to the second time the calamity the Grail possessed. He saw his brother gain a new power, and learned of his Fate, the fate that his Ideal would one day bring...

Yet when the World asked whose life's power he wanted. Jaune knew that he could and would only choose one person's power.

That person was his brother - Shirou Emiya - Archer.

But even still, Jaune knew that even if his life was gonna be hypocritical... it was a life where he wanted no one to ever cry, and he couldn't help but admire that Ideal. An Ideal that destroyed a life, but ultimately still proved that it was a dream worth chasing. A dream he and Shirou both promised to keep!

When he gained the power of Archer his attire was almost the exact identical except his were yellow and white respectively against red and grey he wore. His bow was even Yellow.

At the end of the War where another Victor hadn't been confirmed, yet again, the magic activated and transported Jaune to another World. A World where he met a family of Mages who didn't know of the Holy Grail War, a family who hadn't experienced the War at all.

The Arc family.

Yet, despite his warnings, fell for Leff's plan hook line and sinker. No, everyone fell for it and this was the result. It was a miracle Leff wasn't dead yet, killed by Ozpin and his people.

He sensed all of them deep down below in the basement.

/

When Jaune finally regained some sense of his surroundings he teleported to where the Grail was stored, deep underground. When they all arrived down in the area all could see that it was a deep catacomb which was likely created by Leff as a means to store the Grail's power. Jaune could feel the magical properties inside the wall; most likely, it was a barrier.

"So, this is where they stored the Grail, right? I feel magic resonating from within, and it's far stronger and potent than anything I've sensed thus far." Fujimaru stated the obvious, Jaune and Mash nodded as they traversed deeper into the cave, "Almost the exact same place where Saber and Archer was protecting it in Fuyuki?"

Walking in deeper Jaune, Mash, and Fujimaru saw a huge crater in the middle of the room and a eerie darkness radiating from within. Suddenly Jaune had his two blades materialized; Kanshou and Bakuya, ready to deflect the Gunshots. Mash deployed her shield to protect Fujimaru and Fou.

Glancing around, Jaune came witnessed to Teams RWBY, NPR and Professor Ozpin, Glynda, Qrow and Ironwood intending to charge in. Realizing that Jaune and his two friends were cornered Jaune took Mash and Fujimaru and teleported away.

They appeared a few feet away with Jaune who had to react quick as a red blur suddenly appeared infront of him, trying to chop his head off. With speed unlike the girl who was attacking him Jaune blocked and then successfully countered with his twin swords. The teen girl was shoved a few feet away as she gripped her Scythe.

H-He couldn't do this! That day... That day had messed him up as he still had nightmares, but... what Leff would wrought was gonna be far worse. So, he just had to put on a brave face and get through this, even if he was terrified of them... Even with all this power, their visage still scared him deeply.

Mash and Fujimaru knew this and they quickly tried to intervene. Jaune gestured for them to stay back as a last line of defence. He was a Hero of Justice like his older brother, and a Hero doesn't get scared.

"Who are you?" Ozpin asked, his cane at the ready, no - wait, everyone's weapon was ready. This was exactly like that day Five Years Ago.

"That does not concern you. The only thing you need to know is that I've come for the Holy Grail and Leff Lynor Flauros." Jaune explained, "You all know the devastation of the Grail. Why not hand it over?"

Everyone's eyes widened as they heard a seeming stranger talk about what lead to the fall of the other three Kingdoms.

"How do you know about that?" Ozpin asked, his form glowing. At one point he'd have been deathly afraid of the Headmaster of Beacon Academy, but no more.

"What did Professor Leff do?" Ruby asked, her eyes shining with pure innocence, innocence that would've fooled anyone else, but not him.

"He... He ruined my life! Everything and everyone I ever cared about is dead because of him! That Monster is gonna pay whether or not you are in way." His two blades were pointed at the group infront of him.

With inhuman speed Ruby Rose was flying through the air crashing into wall, all while Jaune had a deathly serious look on his face. Weiss and Yang charged in with Weiss using her Time Dilation glyph (Which had no effect on him by the way) and Yang's eyes glowing red.

Clearly they were trying to end this rather quickly - why? When they were nearly at Jaune he blocked Weiss' rapier and Yang's fist with both swords. He spun in a circle with both of the sword's handles making impact on their waists.

And, they met the same thing Ruby met - a face full of concrete.

Jaune's senses noticed something coming at him with speed - it was Blake. He blocked and countered, he saw as Blake's body flew back, but also as one, Blake sped through the shadow aiming for his throat. Blocking the sword with his swords in an X position, he kicked Blake in the stomach and quickly followed up.

He had to tire Blake out and go on the attack; it was the only way to go. He could counter but that would give the others time to advance. By the time his thought was finished Blake was already on the ground.

Hearing a war cry Jaune knew exactly who came bursting in through the air. He spun around and threw Kanahou and Bakuya at Nora who couldn't dodge. Luckily, his blades didn't slice as he hammer blocked the sharp edges, but the force at which he threw still slowed her down.

"You're weapon less."

Jaune heard a familiar voice, his eyes widening as he imagined a spear sticking out of his shoulder. He quickly regained his composure and jumped in the air a huge yellow bow forming in his hands and a sword in the other, which he would use as the arrow.

He saw Pyrrha's eyes widen as she called her shield to the front (it wasn't gonna help.) Jaune could quite literally feel the air get knock out off Pyrrha as her shield (Which although held together) still reeled from the arrow's impact, her shield arm might have been broken indicated by the scream of pain.

It wasn't actually a surprise that Jaune had a smile on his face at the pain he inflicted on the person who betrayed and attacked him, on the people who attacked him and killed his adoptive family.

And, so he fell to the ground relatively alright with his Yellow Bow and regarded the teachers with at least a bit of wary. Suddenly clapping could be heard coming from the crater where the Holy Grail's magic was coming from.

"My, my... so very good to see you again, Dear boy, Demi-Servant, and 48th Master potential. How have you been?" The target, Leff Lynor asked, a sadistic smile playing on his features.

"You!" Mash and Fujimaru screamed in anger, Mash taking stance side by side with Jaune, "You'll pay for what you've done to Olga!" Fujimaru yelled.

"I am quite frankly surprised you all managed to Rayshift into another Universe, but with Alaya and Gaia's lapdog here it must've been no trouble at all." Leff surmised.

Everyone's eyes widened as they heard the same name the teen they betrayed say all those years ago. Who really is this silver haired man? And why is Leff acting so unlike himself? If they didn't know better, they would assumed he is Evil like the silver-haired man was saying.

"To think Jaune Emiya would once again be standing in my way..." Those words sealed it as Teams RWBY, NPR and the teachers eyes widened. That... was Jaune? The person they all tried to kill to obtain that wretched Chalice of Despair.

"So you know who I am. What of it? My only mission is to kill you and destroy that Chalice." Jaune spoke, his grip on his bow tightening as a sword appeared in his right hand.

"But, can you? The last time we met, you couldn't even put a scratch on me, even with the Counter-Force helping you it'd be extremely hard. Also what good would that do if you kill everyone in here?" Leff said matter-of-factly.

"Actually, I don't actually care if "They" die. The only two I really care about is Mash and Fujimaru." Jaune said, placing the sword in the bow readying to fire.

Pyrrha and everyone had to say that it was as a steel knife had been thrust into her their heart, Pyrrha expected something else from Jaune, but she should've known that had to be it. They betrayed him and nearly killed him so this was the only way it could go.

Jaune pulling back the string was stopped as Mash stepped in the way, and with a stern face looked Jaune in the eyes.

"This isn't right..." Mash whispered, her arms spread out to signal "No". Jaune sighed, as he realized that Mash, Fujimaru and even his older brother Emiya would never resort to that. His sword vanished as his eyes widened when he saw an energy beam head for Fujimaru.

He grabbed Mash by the shoulder and teleported to Fujimaru. The beam of pure energy impacting the shield right after. It stopped after a few moments.

"J-Jaune... is that you?" Jaune heard the meek voice of Ruby from behind him. When he turned around, he saw that she was on her knees, her whole body shaking as she cried. He didn't even acknowledge Ruby as he turned back and saw a new addition beside Leff.

He remembered the girl as the one who used magic Five years ago. He heard one of the teachers call out her name, Cinder? By their expressions, he could see the shock evident on their faces. She was accompanied by a big brute of a guy, a small lean bearded man and one that kept annoyingly laughing.

Then appeared a woman who quite literally looked like a demon? The power resonating from her was the same as Grimm. He heard Ozpin and everyone else gasp as they saw the woman, so obviously they knew who she was, and he did not.

"Meet my partner," Leff introduced, "Salem the Witch." The woman bowed as she greeted them all. Suddenly cries of Grimm could be heard from above. It was at that moments the wristbands of Jaune, Mash and Fujimaru blared with a beeping sound.

Behind Fujimaru a hologram appeared with Romani Archaman.

"Fujimaru! Mash! Jaune! This is bad! Ilya is trying on some new clothes and she's demanding Jaune come and praise her. You'll have to drop wha-! Oh, bad timing?" Romani asked, all while scratching the back of his head.

"You think?!" All three simultaneously yelled.

"A-Anyway, There's nothing else we can do... That World is already starting to incinerate. At the rate its going everyone and everything will be dead in ten minutes tops!" Romnani explained, with a frown on his face, "I'm sorry but more singularities are popping up in Earth's past." Romani spoke urgently, "Chaldeas is barely holding it together, we need you." Romani finished.

Suddenly the cave they all stood in started to collapse.

"Oh, I would love to stay and chat, but Humans to kill and all that, so toodles!" Leff spoke, as him and the others disappeared. Jaune kneeled on the ground and hit the ground with his fist.

"Dsmn it! Another World... Come on let's go!" Jaune said, standing upright.

"We can save them! We have too, Jaune. Everyone else is dead by now... It's our job to protect them." Fujimaru gestured to Ruby and the others. Jaune looked at them with contempt "I'd rather just let them die. But you're in charge so do what you want. One thing, if either of you are planning on betraying us, I'd kill you where you stand, you got me?" Jaune warned, a deathly blue mist wafting around his body.

"Romani, people are here who can help. Can your Rayshift them as well?" Fujimaru spoke to the hologram. Romani nodded "They seem to have Magic circuits so it's possible."

"You guys go on ahead. I'll use the Counter-Force to get there." Jaune said, as he walked to the crater. Fujimaru ushered Team RWBY, NPR and the adults over towards him and then the ground started to glow blue as a light engulfed them all.
