Author's note: I have only seen three other RWBY Inuyasha crossovers at the time I started writing this. One had some potential during the first chapter, but in the second one, they ruined it(not saying specifics, figure it out on your own)and the other two weren't going anywhere. I wanted one that would actually go places. This is going to be a serious story but I want to write another one that is just a crack-fic. Also, since Miroku sucked up Kaguya in the second movie, he is immortal, at least in theory. In this story, he is. Kagome is bound to Inuyasha, making her virtually immortal as well. Sango is not. End author's note.

Japan

It had been around thirty years since Naraku's fall. After the first few years, they realized that out of the six of them, Sango was the only one that was noticeably aging. They were all worried about her and their children. They didn't know what to do, until one day, two strange men, one wearing a dark cloak and the other wearing a bright cloak, showed up in the village seeking help.

Inuyasha went outside to talk to them.

"We need your help," the one with the bright cloak said.

"Why do you need our help? It seems to me that you're strong enough to handle it yourself." The two strangers looked at each other, than back to the yokai.

"It seems you will need a reason for why we need your help and why we can't do it ourselves," the brighter cloak stated. "Would you get your family please? You will all need to hear this."

"How do I know this isn't a trap? Either you tell me now and let me decide what to do then, or, I'll send the both of you to Hell." He had an angry glint in his eyes. The brighter of the two strangers sighed.

"Very well. I'll tell you. My brother and I have made a grave error. A world that we created will be destroyed by the rules that we put in place because of it. We have taken notice of you and your family. If you save our world, we can make your friend young again and live for as long as the rest of you will," he replied. Inuyasha listened closely and came to a decision. He would have to find out more.

"What is this world called? What is it like? What is the grave error you made? What are the threats? How do we destroy them, and why can't you do it yourself?"

The darker cloak decided to speak. "The inhabitants call it Remnant. They have abilities unique to them that they call semblances. As for the grave error, a very long time ago, there was a woman who would use us for her own gain. She wanted us to bring back a lover of her's. We could not do that because it would have upset the balance of the world. She would not let him go…" he paused.

"So I made her immortal, to learn the importance of life and death. Only then would she be able to rest."

"What is her name?"

"Salem," the dark one replied, "after a few hundred years, she came back with a huge army to try to destroy us, but I ended up destroying them, along with the rest of humanity. After that, we left and let it try to grow once more."

The light one spoke now.

"We were the gods of that world. The threats to the survival of the new people, are the grimm and Salem. She is still alive and trying to destroy Remnant. We cannot intervene ourselves because we put rules in place, stating that we would not interfere with the affairs of the human race or how the planet grows."

"That is why we cannot do it ourselves. Unfortunately, you will have to figure out how to destroy her on your own. Will you help us with our problem?" the dark one asked.

"Are you two fucking idiots? Why would you make someone immortal to make them understand something like that. Obviously it didn't work because you wouldn't be here right now asking me for help." He sighed. "I need to see what the others think of this." He stood up and walked back into the village. The two men waited for several minutes before the man with the silver hair came back. Following close behind him were five others. One was a monk, another was a priestess. The third had two fox tails, the fourth was a small two-tailed cat with strange markings, and the fifth was a woman of about fifty, with silver streaks in her hair.

They all sat in a circle, with Inuyasha at the head of the group.

"We will bring you to a place where we can speak," the two cloaked figures said in unison. They both glowed faintly. The world disappeared and left behind a white emptiness with a slight yellowish tint to it. Inuyasha already had his hand on the Tessaiga, ready to swing.

"Do not worry," said a voice in a calm tone. "You are in the realm between worlds." They looked to where they heard the voice and they saw two figures. Both were very tall, at least twelve feet.

One was golden and the other looked to be a purplish color with black highlights. The golden colored one had large antlers and the other had ram horns. They looked kind of like Muso when he was stealing faces from people.

"This place is beyond time. The time that you spend here will not affect you in your world," the dark one said.

Miroku stepped forward. "We'll do it." He felt a hand jerking on the back of his robes. Inuyasha was pulling him back toward the group.

"You don't speak for the rest of us, Monk. That's my job." Kagome looked at Inuyasha.

"If another world is in danger and we're the only ones who can save it, shouldn't we?" she asked him. He looked toward the gods.

"Of course we should, but, there are two things that I want to know. One, how long will we be gone and two, how will you get us there?"

The god of light spoke.

"In your world's time, you will be gone for no more than the blink of an eye, but in the other world, as long as it takes."

The god of darkness spoke next.

"And as for how we will get you there, there is a slight problem. We cannot bring living things into Remnant from other worlds, so we will have to turn you all into a statue for a little while. Is that alright?" Inuyasha and the rest of them turned to each other and talked about it for a few minutes. They turned around to face the gods.

"We'll do it," Inuyasha said.

"Good," the god of light, "one more thing. Monk, we will give you a form of the Kazaana that will not expand and will not kill you. It will also be unable to pass on and will be completely under your control. Now for our end of the deal." He raised his hand and Sango started to glow slightly golden.

Her age was reversing. The silver in her hair was receding and her wrinkles were smoothing out.

She looked like she was eighteen again. She didn't know what to say. Miroku was looking at her with utter shock. The love of his life would be able to be with him forever. He felt a power from his hand. He opened his right hand and the Kazaana had returned.

Vale Borders

Two soldiers were looking at the scroll as the broadcast just cut out. They heard the growling behind them. They turned around and started firing on the grimm. There were too many of them for their guns to do anything. They had to turn and run for the defense of the city walls. They put the city on alert for the incoming attack.

Ozpin heard this happening in his office. He got out of his chair and walked into the elevator. He set it to the ground floor. The door opened and he stepped out the front door of the building. He was walking past the statue when he sensed something.

That was odd. What he was sensing was coming from inside the piece of carved rock. He looked up at it and something unexpected happened. The sword in the Huntsman statue's hand, pulsed. It pulsed again and it spread across the statue. He watched it closely.

The whole statue pulsed and six figures stepped out of it.

In the City

"We're going to get overrun," Qrow yelled as he transformed his sword into its gun form. Ironwood and Glynda were with him, keeping the grimm off civilians and each other.

"He's right," Ironwood replied, "we can't keep this up much longer." Dozens of grimm were coming at them in a stampede.

A wave of incredibly powerful golden energy suddenly coursed through the horde, enveloping them completely. When it stopped, not even grimm dust was left.

A silver-haired man with cat-looking ears jumped over a building and landed in front of them. "What the fuck are these bastards?" the man yelled.

Beacon

Six figures stepped out of the statue. Three were humans, two were faunas and the final was a giant, flaming, two-tailed cat. They took a quick look around.

"Do you sense that?" one of them asked the others. This one was wearing strange red clothing with a sword on his waist. He pointed into the city. "There's a huge aura coming from that direction. It feels malevolent and there are dozens of smaller ones coming from there as well. They're humans."

He turned to the others, "Kagome, you and I will take care of whatever that aura is coming from. Miroku, Shippo, you get the people out of there. Sango, Kirara, you handle the smaller dark energies in the city."

They all nodded in agreement and took off.

Slightly Later

That Night

Adam leaned over Blake.

"I will make it my mission to destroy everything you care about." Shots were fired nearby. They looked outside. A blonde girl with shotgun gauntlets fired into someone.

"Blake. Blake," she called. Adam looked back at the girl on the ground. The look on her face confirmed it.

"Starting with her." Adam stabbed Blake in her abdomen. She screamed and that got Yang's attention.

"Get away from her!" She fired behind herself and went flying through the air. She was about to hit him, when Adam drew his sword.

Yang felt an arm across her torso and her force was stopped almost immediately, her aura nearly being completely depleted on impact. Adam hadn't even seen it coming. A golden staff had blocked his blade and a man appeared in between him and the person he had intended to kill.

The blonde girl fell to the ground and this new opponent swung around with the force of a boulder and nailed Adam in the face with his fist, sending spiderweb cracks all across his mask, putting him through the window behind him and outside.

"Shippo, he's an enemy," the mystery man yelled.

"Got it. Smashing Top." A gigantic spinning top appeared out of a puff of smoke and drilled into Adam's spinal column.

Beacon Tower

Pyrrha slammed Juane into the locker and set the six-digit code. It started to fly away as Juane was yelling from inside. She ran through the front doors and saw the elevator. A hole had been ripped through the floor and the ceiling.

She stepped inside and activated her semblance. Her soul took hold of the elevator and they shot upwards. She got to the top of the shaft and threw her shield at the cause of all this. The woman known as Cinder knocked the shield away as Pyrrha came flying out of the elevator.

Elsewhere

"Jaune, where are you," Weiss asked him.

"Don't worry about me! Please, you have to save Pyrrha."

"We will. Are you alright?"

Juane screamed as he threw his scroll against a rock. "Please, save her."

"He said she's at the top of the tower." Ruby looked up. "We have to get up there."

"I can help you." They turned around to see a woman on a giant two-tailed flaming cat. "I can help you get up there." Ruby and Weiss looked at each other.

"Alright, I'll go with you. Weiss, you go back to the others and tell them what's going on." Weiss nodded. The woman grabbed Ruby by the arm and swung her onto the back of the cat.

"Hold on tight," and with that, they took off.

The Top of the Tower

Pyrrha had her sword wrapped around Cinder's neck. She had a hold of the blade and split it into three pieces. The dragon roared outside as it crashed into the tower. The roof was cleaved away.

Pyrrha was on the ground as Cinder walked towards her with both swords in hand, an arrogant smile on her face.

"Hiraikotsu!" The two of them looked to where they heard the voice from and saw a gigantic disk spinning towards Cinder at tremendous speed. It almost hit her, but she had just enough time to bring both her blades in front of her to stop the attack, at least, that's what she thought.

What neither of them expected, was the disk that had hit Cinder's swords had stayed in place, sending cracks through them and kept grinding away at them.

Sango, Ruby and Kirara landed. Ruby ran over to Pyrrha and helped her to her feet. The Hiraikotsu disengaged with Cinder and returned to Sango's hand.

"You two," she turned towards Ruby and Pyrrha, "get on Kirara and get out of here."

"But-" Ruby protested.

"Don't argue, you can't help me. I can handle this. Get her to safety." Sango was engulfed in fire. It dissipated and she was standing with the Hiraikotsu in front of her.

"Go!" She pulled Hiraikotsu out of the stone and readied it. "Kirara, take them to Inuyasha." Kirara grabbed the two girls in her teeth, threw them onto her back and took to the skies. Cinder grew angry as her prey flew away. She screamed and sent a fireball at them.

The Hiraikotsu intercepted the flaming sphere and returned to its owner's hand.

"I won't let you get them. You're fighting me now," Sango said angrily. Cinder once again wore that smile of hers.

"Fine then." Cinder conjured her swords again and attacked.

Beacon Cliffs

Kirara landed with Pyrrha and Ruby on her back. They got off and ran towards the others. The people who had come out of nowhere were standing near the air transports. Ruby finally got a good look at them. (Previous Description for Them nonexistent, you know what they look like) Ruby set Pyrrha down with the civilians and ran over to the one in red with the giant sword. He looked at her in slight confusion.

"You have to help your friend." Inuyasha tilted his head at her.

"What do you mean?" he asked the small girl. He looked up and noticed the giant black dragon flying around through the air. He ignored Ruby from that point on. He hoisted the Tessaiga onto his shoulder.

"Kagome."

"What is it?"

"Come on. We got something else to deal with." He ran past Ruby, completely forgetting she was there. He stopped next to the giant cat known as Kirara.

"Where's Sango?" he asked the feline. The cat looked to the top of the tower. Fireballs were flying everywhere. He noticed the Hiraikotsu flying through the air.

"Kirara, go help Sango." The cat roared and took off. Kagome came up next to Inuyasha.

"What's the problem?" Inuyasha pointed the Tessaiga toward the dragon.

"That's the problem. That Dragon is circling the tower and Sango's up there. I sent Kirara back to help her. Shippo!" The two-tailed kitsune took notice of the dragon as Inuyasha got his attention.

"I need you to get Kagome and I up there," he said, still pointing at the dragon. Someone else ran up to him. What was with these people?

"You couldn't possibly take that thing down." It was the man wielding the scythe from earlier. "Even with that energy wave that destroyed the stampede, you won't be able to take it in one shot."

"You ain't seen nothing yet." Inuyasha smiled as the Tessaiga landed on his shoulder.

Earlier That Night

Blake saw the spinning top appear, but she still didn't believe it. The man who had punched Adam through the window knelt down next to them.

"Are you both alright?" he asked them. Yang was still dazed from the impact. Blake was bleeding slightly.

"More or less, but who are you? I've never seen anyone but Ruby who was that fast before," she replied.

"My name is Miroku and I'm here to help. We need to leave here." He turned toward the window. "Shippo, come on. We have to leave now. Let him up." The spinning top disappeared into a puff of smoke. A man with two tails sprouting from the back of his waist stepped through the shattered window. He was wearing armored boots along with a really weird looking outfit.

Adam stood up, and Blake saw him. She was terrified of what she thought was about to happen. Miroku noticed the look on her face and turned around. Adam was already past Shippo and coming at Miroku. He drew his sword to take the monk's head, only to have it stopped by the golden staff again.

"I will kill you for that human." Miroku looked at him like he was stupid.

"No you won't." Time seemed to slow down as Adam felt a building pressure in his gut. He looked down to see Miroku's fist going into and almost through his stomach. He was sent flying backwards and Shippo kicked him out of the air and into the stone floor. His aura had been depleted by the top and broken by the punch to the gut. Now he was unconscious.

Miroku looked to the kitsune. "Shippo, you help them and I'll keep the monsters off you." The two tailed man knelt down next to them and took each girl in one arm and put them on his back. He then wrapped one of his tails around each of them for stability. The four of them bolted from the cathedral. What they saw outside was another horde of grimm on the stampede.

Miroku stood in between the others and the incoming monsters. He embedded his staff into the road and opened the cloth on his right hand. A black light emanated from his palm and a torrential wind ripped through the grimm, pulling them toward the man named Miroku. Instead of hitting him, they just got sucked into the source of the wind.

He closed his hand and the road was now barren.

"Who are these people?" Blake asked herself.

Later That Night

Inuyasha, Kagome and Shippo were flying through the sky on a disk of the kitsune's Fox Fire. They got above the giant dragon grimm and Inuyasha jumped off, the Tessaiga shining above his head with the adamant spears growing all across the blade.

"Kongosoha!" He swung the huge blade down and hundreds of diamonds the size of Ruby started ripping from the Fang and impaled the dragon in so many places so hard that he knocked it out of the sky.

The monster crashed into the cliffs a mile away from the evacuation site and rolled through a large portion of the city. Inuyasha seemingly ricocheted off the corner of the cliff as he went after the monster. The inu-hanyou held his blade above his head and hit the ground with it as he landed. A wave of blistering yellow energy went ripping through the city until it hit the monster.

There was a blinding light as it continued through the buildings. The next thing anybody but Inuyasha knew, the wings of the giant dragon grimm were flying off and disintegrating. Unfortunately, it was still alive.

"Fuuck! Kagome, shoot the son of a bitch," he yelled up at the priestess.

"Right." She readied an arrow, aimed and let it loose. As soon as she let go of the bow string, a beam of white light shot forward. It was at least a hundred feet in diameter. Nobody had ever seen something like this coming from a bow or anything else before. The beam of light struck the dragon and enveloped it. A few seconds later, the light dissipated and the dragon was gone.

Everybody on the cliff was speechless. RWBY looked on at the "battle" and were utterly shocked.

"Awesome!" Ruby.

"Amazing." Weiss.

"Incredible." Blake.

"Unbelievable." Yang.

At the Top of the Tower

Cinder looked down on the destruction of the city below. She couldn't believe what she was seeing. She heard the Hiraikotsu coming in again, and she jumped to avoid it, only to once again get knocked to the ground by the giant flaming cat. She stood back up as Sango came flying at her with her katana drawn out in front of her.

Cinder blocked the first strike, but only barely. Sango knocked the two swords aside. She spun around and knocked Cinder's feet from underneath her. She fell to the ground as Sango caught the Hiraikotsu. She raised it above her and brought it down where Cinder's head was only a second ago.

The Fall Maiden stood and shot a fireball at the Yokai slayer. Sango had to jump back to avoid the shot. She landed on her feet and bolted forward with her katana in one hand. Cinder conjured her blades again and tried to intercept. Kirara landed next to her, whipped around and hit Cinder with her tails. She was sent flying from the force of the giant cat.

"Kirara, back," Sango informed her friend as she donned her poison mask.

"What are you planning now? If you're planning anything that is." Cinder was pissed off, and she was getting sloppy.

"Poison powder." A noxious smoke enveloped the fire eyed woman. She was suffocating from the fumes of whatever it was that was thrown at her. She put her hand over her mouth and nose to try to keep some of it out.

"Hiraikotsu." Cinder could barely see but she knew what was coming. She saw that gigantic boomerang flying at her again, but the gas had slowed her movement, and she couldn't react in time. She felt the bone connect with the left side of her face. A burning substance was on the end of it. What was going on?

Sango knew that her opponent possessed some sort of power that could be caught by her weapon. It was fiery too. It struck Cinder across the left side of her face, burning it almost completely off. Sango had not exactly intended for that to happen.

Cinder fell off the side of the tower. Kirara went after her. She came back over the edge holding the other woman by her left arm. Fire was spewing from the Cat's mouth as Cinder screamed. She could feel the gigantic teeth ripping through flesh and crunching bone, with the heat and flames burning through everything that the teeth weren't already boring into.

The giant cat slammed into the stone of the tower roof. Cinder was sent flying through the air as her aura flared and shattered. Her arm separated from her shoulder as she sprawled across the ground, unconscious. Kirara spit out the severed limb. She had purposefully cauterized the wound with her fire-breath so the attacker wouldn't bleed to death.

"Alright Kirara, let's go." The slayer got on the back of her friend and they flew into the sky.

Beacon Cliffs

Ruby, having just witnessed the most impressive thing this world had ever seen, wasn't really that excited about it for some reason. She was kneeling next to Pyrrha, making sure that she really was okay, when she noticed the woman and the strange cat creature that had helped them, was coming in for a landing.

They touched down as Ruby came to meet them. Sango dismounted her friend and greeted the girl.

"Thank you for saving Pyrrha. Thank you so much," Ruby said as tears started to flow from her eyes. She tried to wipe them away, but they just kept coming. She was so happy that she hadn't lost another friend that day, and that thought made her sad.

Sango grasped the younger girl's hands and smiled at her warmly. "I told you I could handle it didn't I?"

"You did," Ruby replied.

"My name's Sango. What's your's?"

"It's Ruby." She was still crying a little bit, but was now smiling.

"Well Ruby, why don't I meet your friends. Than you can meet mine, okay?"

"Sure." Ruby tugged on Sango's hand as she pulled her toward the rest of RWBY and JNPR.

Author's note:And that's the first chapter. Tell me what you thought of it, leave reviews, favorite and follow. Check out my other stories and go to another writer by the name of David Castro, read his story Let the Sun Breathe Life Again and review it. Why am I doing a promotional segment, I ask myself.

But seriously, go check out David Castro and read his Let the Sun Breathe Life Again story. It is going pretty well so far and he needs more support. As far as I know he just started too, so go read his stuff, and if you're going to review his or my stuff, don't be an asshole about it. Five other people that reviewed one of his stories were being assholes about it and I don't understand it, so don't be an asshole, be nice to each other, because this, this is all we've got.
