Hey guys, this is going to be my first Crossover fic. So I hope you enjoy. I just want to make some quick notes. 1. Masamune will have his SW4 outfit and weapons cause it looks the most badass to me. 2. His horse will be the Iron coat, cause it kinda matches his armor a bit. And finally 3. I want some opinions here. You guys are free to give me some suggestions. Anyway, I do not own RWBY as it belongs to Rooster Teeth and Samurai Warriors as that belongs to Koei co. Anyway lets' get Started

Chapter 1

"Fire!" Yelled Masamune as he pointed his Saber while riding on top of his steed. Cannons shoot through the air, sending many of the Toyotomi troops flying through the air as many were now corps. "Now Charge!" He lead his men to the forest to help out both Kojūrō and Magoichi while Kaji was occupying troops to the west. 'I'll show that monkey that a dragon is the true ruler of Japan.' Masamune said to himself as he was slashing his sabar at the enemy troops that were either trying to fight him or were running away from him.

As what seemed to be a easy victory towards the young ruler of Oshu quickly became a easy turn as the Toyotomi soldiers they were chasing triggered a trap. as a bombardment of cannon fire took them by surprise. As the cannon fire increased, the men of the Date retreated. "Fools don't you dare retreat when we have the upper hand!" He told his men but they did not listen to him as he was killing the Toyotomi soldiers. "I Said-" But he was cut off as a cannon ball exploded near him making Ironclad whine back as he tried to take a hold up the reins but failed to do so as he fell to the ground with his back first as the landed make him unconscious as the last think he saw was a white light.

As Masamune awoke, he quickly got to his feet and saw that he was not in Oshu forrest. "Where am I?" He said to himself as he checked himself out to see if he was shot or stabbed anywhere while he was knocked out but found no such thing as his armor was in one piece. 'Maybe the men came back for me and had to carry me away from the battlefield. But it doesn't explain where I am.' Straightening himself up and checking his that he still has his saber, two flintlock pistols and two full bags of gold coins as he walked thought the forest. "Kojūrō! Kaji! Magoichi!" He called out but no response was heard. "Damn it where are they? Unless... no, there is no way they could be dead, they are too tough to be killed, especially Kojūrō." Soon he came across some red eyes behind the bushes as a pack of wolves with white masks came out. Masamune quickly drew his saber and stood his ground, soon one of the wolves came charging at him with it's claws, however the young lord cut off the claws and slashed diagonally as the wolf was split in half. After that two other wolves tried but they ended up being killed as well then Masamune took to the offensive as he took down two more wolves with his saber, making the others want to retreat. "That's right, run." He shouted to them as he sheath his saber as he kicked one of the beasts with his foot. "Never saw an animal like this one. Could I be Kai? Or Am I in Echigo province?" Then gun shots were heard not too far from were he was. "If someone is firing then that must mean I'm close to a village." He raced himself to where the noise was coming from.

As he got closer the gunfire, he then noted two woman around his age looking at each other with two bears that looked like the wolves he was fighting with earlier. One of the girls was a long haired blonde with a tan vest, a yellow low cut crop top, with what looks to be gauntlets over black gloves, black shorts with a tan like skirt that covers the back with long brown boots and a orange scarf around her neck. The other girl had long black hair with a black bow on top of her head, black low heel boots with matching stockings that goes to her hip and black ribbons both of her arms, a white sleeveless undershirt with a small black buttoned vest with coattails and white shorts and what appears to be a short sword behind her back.

"I could have taken him." Said Yang.

"I'm sure you could." Replied Blake. "I just wanted to get a kill for my own."

'What are these two and what is with their clothing?' Masamune thought to himself. 'They don't look like peasants, but not like ninja's either. They should know where I am, maybe they saw my army. But what if they're the enemy and they are with Hideyoshi. It's a risk I have to take." Getting out from the bushes and headed towards them. "Hey, you two!" He shouted as he got their full attention.

"Who is that?" Yang asked. "I didn't see him on the launching platform."

"Me neither but he dresses very odd." Blake said being a little on guard.

When Masamune was foot away from them, he began to question them. "Have either of you seen the Date army around?"

Both girls looked confused to his question.

"Who?" Yang asked.

"The Date army you fool." He asked again more demanding.

"What did you say you pirate!" Yang getting angry.

"Pirate!? I'm a Samurai!" Masamune yelled angrily almost to the point that he drew his saber.

"A pirate Samurai?" Yang asked more sarcastic than serious.

"NO!" Masamune getting more angry. "I'm the Lord of Oshu!"

"Gazuntite."

"He said Oshu, not Achoo, Yang." Blake corrected her.

"Oh... where is that?" Yang asked.

"Actually I never heard of it myself." Blake looking at the one eyed warrior.

"How can you not know! It's-" Before Masamune could say his next words he then realized what they said. 'Wait a minute, they never heard of Oshu? Then they are not with Hideyoshi, Plus they don't even look Japanese. I have to ask them, right now.' "Am I in Japan?"

"Nnnope." Yang said with a stupid grin on her face.

" You're in the Emerald Forest outside of Beacon Academy in the city of Vale." Blake explained.

"Great, first I'm in a battle being ambushed, next I wake up in a Forest far from who knows where." Masamune mumbles to himself as he kicked the dirt. 'That may explain those weird wolves that came after me. But how did I get so far away from home? Could it be when I got knocked off my horse that strange light did something to do with it? It's best to have these two with me weather I like it or not.' "Hey, if you don't mind, I want you two to take me to the nearest village."

"Sorry, no can do, we're kinda in the middle of something." Yang said scratching the back of her head.

"That's fine then, I'll join you, it's better then getting ambushed by what's out there. And you can tell me more of where I am and more about this land." Masamune pointed out to them.

"I guess you do have a point, and I do have some questions." Blake thinking this though.

"Alright, Just try to keep up Mr. Samurai Pirate." Yang going on ahead.

"I told you before, I'm not a pirate you peasants." Masamune said annoyed.

"If you don't want me to call you that then you better tell me your name." She said. "I'm Yang Xiao Long and this is Blake Belladonna now what's yours."

"Masamune, Masamune Date." He said. "Seventeenth head of the Date clan and the One- Eyed Dragon of Oshu."

"That's a mouthful but let's get going Masamune." Yang said.

Without another word said, the three of them started to walk though the forest. The tense air around them didn't help as much either.

"So Masamune, what kinda land is Japan like?" Blake breaking the silence.

"Right now the country is at war with itself." Masamune said in distaste.

"Wait your country is at civil war?" Yang asked slowing down her paste.

"Indeed, a civil war to see who is right to rule the land. It all Started during my grandfather's time, Harumune Date, the land is ruled by an emperor but he has little power and is only a figurehead, the one with the real power over the land is the Shogun. The previous Shogun, the Ashikage was a weakling and so my grandfather and many other clan members rose up against him."

"That's very interesting, so did anyone succeed?" Blake looking so interested.

"One person did but he died shortly afterward. His name was Nobunaga Oda, many called him the demon king for he was one of the first feudal lords to use firearms. He was not the Shogun but he pulled the strings of his own until he was betrayed and killed by one of his own generals. And now there is this monkey called Hideyoshi Toyotomi who is slowly taking control of the land but he won't get too far once I come back to my army and take the land for myself."

"So let me get this straight, your telling me you plan on taking on a big army and plan to succeed?" Yang asked taking it all in. "That's either you're an idiot or you're pretty gutsy guy."

"Like you're the one to talk." Masamune responded back to her. "I told you the story of my land, how about this land here?"

"It's not easy to describe but I should start with the basics." Blake said. "The World of Remnant is in habited by humans, faunus and creatures of grimm."

"Fanuse? Creatures of grimm?" Masamune trying to get a hold of it.

"Creatures of Grim are like those bears me and Blake killed. As for the faunus they look like humans but may have an animal characteristics for example animals ears or a tail." Yang breaking it down for him. "Not much is known about grimm expect that they take on the form of animals and that they are lured to negative emotion."

"So I have to think of positive thoughts?" Masamune asked.

"Wish it was that easy but no, unlike normal animals, grimm adapt and and choices to feed instead of needing to feed. So they made the schools for Hunters and Huntresses such as ourselves go to."

"So it's your job to fend off these beast as best as possible." Masamune asked.

"Yep and we are keeping it like that." Yang said.

After a few minutes of walking, they reached what looked like a ruin.

"You think this is it." Yang asked as Blake gave her a side glance and walked forward as she follows with Masamune close behind them.

"So this is the place? What so important to be here?" Masamune asked as he saw small pillars with chess pieces.

"This is what we are here for, it's a test from out professor." Yang answered him. "And it looks like we're not the first here." Seeing missing chess pieces.

"Then I guess we should pick one." Blake said looking around with Yang and Masamune.

"How about a cute little pony?" Yang asked holding the gold knight piece.

"Sure." Blake rolled her eyes as well as Masamune.

"You came what you wanted now can we go to the vill-" He was cut off by the sound of a loud scream. "What the hell was that!?"

"It sounds like some girl is in trouble." Yang sounding worried.

"Heads up!" A younger female with a red hood yelled falling from the sky as she collided with a blond by who also flew out of nowhere and both landed in a tree.

"Did your sister fall from the sky?" Blake asked.

But there attention was interrupted by a ursa getting attacked by Nora and Ren.

"It's broken." Nora sounding sad at the dead ursa.

"Nora...please...never do that again." Ren pleaded out of breath. But the orange haired girl was at the relic and picked up the golden rook.

"I'm queen of the castle, I'm queen of the castle." She jumped in joy.

"Nora!"

"Coming Ren." She giggled as she skipped to him.

"Did that girl ride on a bear?" Masamune not sure if he was shocked or confused. But soon his attention was distracted again by a red haired girl being chased by a giant scorpion.

"Ruby!"

"Yang!" They said about to hug each other

"Nora!" Nora coming out of no where then saw Masamune. "Who's the pirate?"

"Yeah who is he?" Ruby asked both her sister and Blake.

"I'm not a pirate, I am a samurai!" Masamune yelled at both of them while Pyrrha.

"Then you might want move." Ruby pointed to the sky as Weiss was falling from the sky with as Jaune tries to catch her but he falls and she lands on his back.

"Good we are all here." Yang said gladly.

"Not if I can help it." Ruby charged at the Scorpion. As she uses her Scythe rifle to speed up and hit the monster only to fail and recoil. She then decided to run and dodge the attacks it gave only to get her hood stuck by the giant monster birds feathers. She tried pulling on her only to it was not working. Then the giant scorpion made it's way to her as it stinger about to strike her. But the blow was stopped by Masamune's saber. Everyone was amazed at what they just saw. "Fool don't just stand there, get yourself out!" He took out his pistol and shoot the feather that was holding her as she joined the others.

"Ruby, thank goodness your alright." Yang hugged her sister.

"Yang, I'm sorry, I-"

"Hey" Weiss walking up to them. "That was pretty reckless of you, you could of gotten yourself killed. But I'm just glade your alright. But if we're going to get thought this, we need to work together."

"Thanks Weiss." Ruby smiled. "Now lets get out of here while the samurai holds those things things off, but first." She walked over to the relic and picked up a gold knight chess piece while Jaune picked up a rook. "Alright let's go." As the all ran off.

"Masamune, Come on!" Blake yelled at him as he kept the scorpion at by.

"I'm coming!" He said to her as he cut the beasts pinchers and made a run for it. 'this would be a lot better if I had my horse.' He ran after the group and caught up between Blake and Yang. As they were running the monster bird flew past them and blocked their way. Now they were sandwiched between the giant bird and the scorpion. "No where to run and no where to hide." Drawing out his saber as the others used theirs. "Listen up first off one of you concentrate on distracting the bird! Then the rest will go to higher groups and the other two attack the scorpion.

"I'm on it." Nora saluted and used her war hammer and turned it into a grenade launcher and fired at the bird. While Blake and Ren attacked the scorpion, giving the other a chance to run. As the they were running Masamune and Pyrrha took turns firing at the scorpion making it to a narrow bridge as it couldn't cross. However their luck turned not so well as the bird slammed itself at the bridge, destroying it. Ren, Blake, Pyrrha and Masamune where on the other side firing at the scorpion as it was swinging it's pincers and tail at them. Them Nora swing her hammer at the ground on the other side as Jaune was send flying with her as she slammed it at the beast and recoil as Blake fell off the edge.

"Blake." Masamune shouted and dove in after her as he grabbed her.

They saw the giant bird coming after them and Blake used her weapon to turn it in to a mini scythe and throw it at a pillar as they both swung in the air as they came close to it the both jumped on it as the both of them slashed at it while running down its tail and both landing on a pillar and was close to Weiss, Ruby and Yang.

"It's tougher then it looks." Blake told them.

"Then let's give it all we got." Yang said as all five of them ready their weapons. and started firing at it. As it was getting hit with all their blows slamming itself to the building as they all jumped from pillar to pillar.

"It's not working." Weiss sighed as she just landed on a piece of a steady bridge.

Both Masamune and Ruby landed on at the same bridge and looked around. "You thinking what I'm thinking." She asked the one eyed warrior.

"Yeah, let's hope it works." Masamune said.

"Alright lets do this. Weiss Cover us" She said as they both jumped to the opposite direction of each other. While they were fighting the bird Jaune, Nora, Pyrrha and Ren were fighting the scorpion and winning as Pyrrha throw her shield at the stinger, landing on it's body and Nora flew into the air and hit the stinger like a nail and making everyone else fly to the other side as the beast fell into the edge of a misty pit.

Yang stood on the pillar firing bullets at the bird as one of them hit it's face making it wince and come after her as it opened it beak and she held it open. "I hope your hungry!" She said between shoots as it got weaken she hopped out of it's mouth before it hit a cliff.

Weiss ran passed Yang and headed towards the bird as it tried to take flight but couldn't as she stabbed it with dust, turning it into ice. "Now do it!"

With that Blake tossed her mini scythe to Yang as she held it onto another pillar making the strong ribbon tight around it as Ruby and Masamune jumped on to it as Weiss pulled the ribbon back using her dust.

"I hope this works." She said as they both got catapulted towards it. Ruby used her scythe and propelled herself towards the birds neck as Masamune used his saber and vertically slashed on top of it's head putting a lot of force into it as it was decapitated in two as they both landed on the edge.

"We did it!" Ruby jumped in joy.

"So we did." Masamune said whipping the blood off his blade.

"Hey I never got the chance to say thank you for saving me back there so thanks.

"It's nothing to worry about. But can you at least take me to the nearest village or castle." Masamune said with a bit of annoyance in his voice.

Ruby looked at him oddly as she titled her head. "I don't know about a village or a castle but I know a someone who can help you."

"As long as he can get my home, I could care less." Masamune grunted.

"Then follow me." Ruby said leading the way as the others climbed up walked in her direction as he followed them.

Once they reached Ozpin and Gilda waiting for them, they each of them gave him the chess pieces. "Very good students. You did great with the exam." He said as he noticed an extra person in the group. "And Who exactly are you."

Masamune walked passed the group as he was face to face with Ozpin. "My name is Masamune Date, Lord of Oshu. I was told that you can help me get back to Japan."

Ozpin looked at the one eyed warrior and examined him. "I can not say that I can help you as I never even heard of this Japan." He said as he sips his coffee. As a noise was heard in right in the back of him as they saw a black and gold armored horse with a bright red mane and tail trotting their way.

"Iron Coat." Masamune whispered as he approached the stallion and patted the animal. "At least I see one familiar face around here."

"I assume this is your animal?" Gilda said to the Samurai. "I would suggest you take better care of your animal."

"It's not my fault. I was in the middle of battle and I was ambushed and the next thing I knew I was in the forest and met them!" Masamune raised his voiced as he pointed to the group.

"Wait, did you say you were in battle and you were attack and the next thing you knew you woke up in the Emerald forest?" Ozpin asked. Did you remember anything?"

"Yeah, I was shot by cannons and was knocked off my horse. Next thing I knew I was falling off my horse and then a white flash happened." Masamune explained.

"I see." Ozpin thinking of the what he heard. "Follow me, we have a lot to discuss." He said as he also turned to his students. "You're dismissed." As they all went there own ways and Masamune got up on Iron Coat and followed Ozpin to where ever he was heading too.
