It may make references to canon, but this story will not follow canon. Mostly.

Jaune opened his eyes to a world of destruction. Smoke and dust floated in the air around him, as fire and debris spread out among the fields he lay upon, and he was pretty sure that there was a crashed Airship in the distance as well.

Confusion was the first thing Jaune could think of. Is it over, had they won? This supposed last stand against Salem was supposed to be the end. Jaune remained standing, so what about his friends? Or their enemies?

Jaune eventually forced himself up, grasping Crocea Mors to lean on as he was having difficulty standing. Jaune couldn't help but scan the world around him, the destruction being far more apparent. He moved his feet forward, using the sword as nothing more than a walking stick, the smoke and ashes from the battle obscuring his vision, almost tripping over debris in the process.

"Ren?" he choked out, pausing in hopes to hear his voice. Yet, none would hear Jaune's cries except himself. "Nora? Are you guys okay?" he cried out in desperation. He had hoped that they were fine and they hadn't heard his voice. But the more he walked, the more bodies he found of Atlas soldiers greeted him instead. Jaune started to feel doubtful.

"Hello?! Anybody there? Say something!" he yelled out hoping to get a response.

He immediately stopped when he found a familiar figure. Jaune immediately dropped his sword and rushed forward, "No... Please..." he croaked, immediately checking for a pulse. He found none, "Ren..." he muttered in disbelief. Ren's magenta eyes once full of life, now dull and empty.

Jaune looked around and recognized more of his friends. Weiss, Nora, Yang. All laying, lifeless. Jaune knew they were dead, yet he hoped that he wawa wrong. He went and checked Nora's pulse: nothing. The same for Weiss and Yang. They were all dead, and Jaune couldn't do a thing.

His breathing ragged and tears already starting to form, he forced himself up off the ground, "I can't be the only one left." Jaune started to wander in hopes to find at least someone alive.

He turned back one last time to the corpses of his deceased friends, "I promise I'll give you a proper burial." he said before continuing on.

The further he wandered the more bodies he discovered. One of Tyrian, alongside Blake and Sun. More of Qrow, Cinder and Raven as well. The powers of the maidens already left Cinder and Raven's body and probably transferred to some randoms across Remnant.

Oscar... His body surrounded in a pool of blood. Ozpin now reincarnated and merged with someone else.

"This is the world... That Ozpin promised us?" Ozpin assured them of a better world, but all he could see was Ash, blood, and death. The kingdoms are in shambles. If the Grimm doesn't finish off what's left of humanity, he was sure that humanity would kill themselves instead. Ozpin didn't care about the state of the rest of the world as long as Salem is dead. They were just being used to fulfill Ozpin goals, to put it simply tools, "Ozpin... How many must die until you're happy?"

Jaune of course knew, but he was too afraid to speak out. He wasn't ready to take on the role of the leader, and besides, who would be willing to listen to him? Perhaps Ren and Nora. But who else?

He continued to look around hoping one of his friends were still alive, somewhere. His eyes stopped on a red cape, and his heart skipped a beat.

"No... No, not you too." he immediately rushed to the lifeless corpse of Ruby Rose. A streak of blood inching out the side of her mouth. Red blood seeped into the already red of her cape. His tears fell and splashed on Ruby's pale cheeks, giving the illusion that it was her who had cried.

"You can't leave me here. This wasn't how things were supposed to end." Jaune hugged Ruby's lifeless corpse as he took notice of a collapsed tower. Salem was inside, yet it was obvious that she was already dead, an arm was missing and Ruby's Crescent Rose was plunged deep through her torso.

Yes, it would seem that they had won, but at what cost? All of his friends were dead. And Jaune was too weak to prevent it, and out of everyone, why was he the sole survivor? It should have been him. He was the weak one. Of everyone, he should have died, he faked his transcripts, he didn't even earn his way into Beacon. But alas, it seems fate had decided against him.

They had defeated Salem and her group, with the cost of basically the entire world. Atlas was taken over by Jacques and the SDC, and the rest of the kingdoms in ruins with the survivors living in fear from the Grimm, or bandit attacks. Perhaps in a few hundreds of years from now, Remnant would be restored to its former state, but Jaune wouldn't live to see it.

Jaune looked up at the shattered moon floating high in the night sky. Swearing that he saw some sort of gash with what appeared to be ribbons tied at the two ends in the sky. He couldn't get a good look as it disappeared nearly as fast as he saw it. He kept seeing those for the past month or so, but he ignored it thinking they were some sort of bird or something. Shrugging that out of his mind he picked up Ruby's cold corpse and brought it to the rest of his friends.

"How many graves am I going to have to dig?" he muttered to himself as he placed Ruby down and unsheathed his sword. He stared at his reflection shining from the blade. All he could see were the dirt and grime littered across his face. There were no wounds, his absurdly large pool of Aura made sure of it. He supposed he would have to use Crocea Mors as an improvised shovel.

Jaune circled around looking for a decent place to bury the deceased. His eyes landed on empty plains that's blooming with flowers. Unlike the battlefield that he is standing in, the fields lay untouched, and almost seem out of place compared to the state of the world around him. Satisfied with the terrain, he got to work.

Jaune stuck his sword deep into the dirt and grass and pulled it out, his arms aching while he dug suitable trenches. He was already fatigued from the battle, and cramps were starting to become apparent, but he continued on anyway, ignoring the pain.

First was Ruby, then Weiss, Yang, then Blake. He even put Sun alongside Blake, they belonged together.

Ren and Nora were next. They were together as always. Next was Qrow. Last was Oscar.

When he finished and looked at all the Graves that are lined up. He couldn't help but wonder, Does the world even know of their sacrifice?

The fatigue finally starting to set in, Jaune leaned back and sat down against an uprooted tree, "Was it all worth it?" he whispered to no one.

Jaune stared down at Crocea Mors. What's the point of living now? There was no reason for him to keep on fighting. They already completed their objective, and there's no one else left to grieve alongside him.

No one would know of their sacrifice. No one would understand their struggles, their pain that they've all been through. No one in the world would know, only Jaune Arc. The last survivor of team RNJR. The last survivor of... Everything.

But little did he know, someone was watching. Through the gaps and a little experimentation on the effects of gaps on different dimensions. A certain gap youkai was watching the exchange, watching Jaune bury his friends. Watching him as he grieved.

This was the Youkai of boundaries, Yukari Yakumo.

Jaune Arc and his story was fascinating to her. She pitied him however, no person should have to experience such a tragedy. As for his friends, there was nothing she could do. Sure, she could have manipulated the boundary between life and death, but it worked differently considering this was another world, another dimension. The rules were different and she had no idea of the effects it could have, and even if she knew now, it would already be far too late.

Jaune Arc was a man of potential. He only harnessed a fraction of it. It would be a shame if he were to die now, and knowing that his state of mind isn't exactly stable when going through such a traumatic experience, she can't have him commit suicide either. He needs something to occupy him. He needs to make friends to replace the ones he lost. He needs to have a new purpose, a new reason to live. Therefore, she has decided.

She would send Jaune Arc into the Land of Fantasy; Gensokyo.

It wasn't the best idea she had, considering the dangers of the inhabitants. Youkai such as herself might not be exactly kind to humans or Jaune, as well as other dangers, namely fairies, ghosts, gods, and even vampires. But, Jaune already had to deal with the Grimm of his world so it was perfectly fine, he already knew how to defend himself somewhat, and if magic already exists in Remnant in the form of the Maidens, and the relics, then he should have no problems with people using magic as commonplace in Gensokyo.

Yukari took a step outside and her feet planted on the grass.

Jaune quickly took notice and grabbed his sword, and stood up, nearly tripping over himself in his fatigue, "Who… are you?" he pointed his sword at her. He quickly noticed the parasol she carried, if Neo wasn't an indication, maybe she had a blade hidden within the handle as well.

"Now, now. There isn't a need for violence, I come in peace." she smiled, "I am Yukari Yakumo. Youkai of Boundaries."

"What's a youkai?" Jaune knew that he was outright oblivious at times, but he was sure that youkai was something that he never heard of at all. Not in the fairytales, not from his parents, or anyone at all.

"Ah, of course you wouldn't know what a youkai is. After all, it isn't something from this world." Yukari answered, pulling out a paper fan to help mitigate against heat from the flames of the current terrain, "A youkai would be… how would I say this? To put it lightly, They are supernatural beings."

However, that just added to his confusion, "Supernatural? So like magical?" he muttered to himself, "Wait, how do I know what you're saying is true? What do you mean 'isn't something from this world'? What if you're just making this up? For all I know that… 'thing' you just came out of could just be a semblance."

"Well, maybe it is, maybe it isn't. But I know that you've seen these before." Yukari opened up another gap, and Jaune took a close look.

Jaune noticed that it were the same gashes that he has been seeing, the ribbons and all. "It's… So that's what I've been noticing for the past few months. You've been spying on me."

"Yep, it's true, you've caught me." Yukari covered her smirk with her fan.

"Then… you've seen what me and my friends have been going through. This war… And you decide to show up now instead of possibly helping us?!" he practically shouted that last part, "If you have something like magic, you could have done something, you could have helped us fight against our enemies, why did you wait till now to show up? If you haven't noticed everyone is dead now!" he gasped for breath as he shouted it all in one go.

Yukari, seemingly unfazed simply stated, "It's true that I could have. However, I am not of this world of yours. The rules work differently so there's no telling what side effects could take effect. This is essentially my first attempt at using my gaps across different dimensions. Also, I'm not watching 24/7. I noticed that time flows differently between our worlds. Your world is slower than mine, and I have a life of my own."

Jaune simply dropped his sword and fell to his knees.

Yukari continued, "You have unseen potential. An environment such as this couldn't possibly tap into that locked potential. I'm sorry for the experiences that you have gone through, and I apologize for your friends, but some things cannot be changed."

"So… what is it you're here for?" Jaune forced out.

"I wish to make a deal with you. Your world is not in the healthiest of states, so I can bring you to Gensokyo, it's where I live. It gives you a chance to hone your skills, and tap into your potential. It's a chance to get stronger. Make some new friends. Get a new perspective on life. And maybe, you could come back and take back Remnant, and prove that you're not weak."

To Jaune, it was a deal too good to be true, "What's the catch? What do you gain from all this?"

"Can't I just do it out of the kindness of my own heart? I simply felt pity for you. It's the least I could do for being merely a spectator. Plus, it could make things interesting along the way."

What have I got to lose? Jaune thought, "Fine. Alright. I'll go to… Gensokyo, whatever that is."

Yukari smiled and opened a gap back to Gensokyo, "Great, take this gap, I'll explain things about Gensokyo and what to expect when we get there. So watch your step, and… Mind the gap." that last part being an attempt to liven the mood.

Yang would've liked that pun. Jaune thought sadly, as he went through the gap. With Yukari following soon after.

(A/N): There are little Touhou and RWBY crossovers so I decided to try my hand at it. With Jaune being the protagonist. I hope I got Yukari right. If there's one thing I suck at is trying to replicate characters. I try my best so bear with me please. Touhou is pretty complex and I am doing extended amounts of research, but there may be some that I will miss, so please tell me if I miss something. I only played Imperishable Night. Also, I don't know if I'm going to continue this story. We'll see how it goes.
