A/N: Oni means demon. Kami mean divine. Sry if I lack a description for everyone on this chapter. The Agarest warriors are from a game called Record of Agarest war. Most of the rest are O.C's.

Enjoy. :)

Jin Kisaragi fear's if he help those eight men he will suffer a bad burden.

Those eight men are Leonhardt, Landaus, Thomas, Duran, Rex, Vice, Schwartz, and Grey A.K.A Heroes of agarest.

Jin enters the room and tells them something

"I can't help you with this matter. However I'll mention these tree things.

One: Tatsuga is the one that caused your teammates to vanish.

Second: The thirteen kami will help you.

Tree: There castle is located the outskirt of town. All eight of them nod their head and set off out-of-town.

When they were walking somehow Thomas remembers something.

Flashback

"Who are you?' Thomas said.

"Oh my dear knight we will meet again" Tatsuga said.

Flashback ends

He remembers the samurai's attire jet black armor with the kanji death, thorns coming out of his forehead; with a katana that spewed out blood and forged by Muramsa.

Thinking about it made Thomas feel horrified.

Throughout the walk no one said anything.

They just know anger is not the good option.

When they got there they saw a castle surrounded by deepwater standing 1000 ft high.

Vice the tallest of the group was skeptical about it. No one greeted them until a person jump out of the castle.

Eight of them pulled out their swords for when things get ugly. The drawbridge was lowered then the person landed a punch to the ground. That person then replied "Oh you must be the people Jin needed help with, by the way the names Kugen".

Kugen was wearing a fancy brown jersey with armored like pants and shoes. Eyes that is red as blood and hair that's fair black. With the sudden greeting Kugen guided them to the middle of the castle. Kugen told them wait while he tells his family members to join and help; with Kugen doing that the eight men talk.

"Finally we now can reunite with our party members." Thomas said.

"Not quite we will be with them soon." Rex said.

"Hmm I just want to get that fool who jack my mistress." Schwartz said.

"Hmm enough talk they are here." Leonhardt, Landaus, Duran, and Grey said.

"Ah you must be the thirteen kami." Duran said.

"Yes we are, now move!" said Necro.

The agarest warriors moved out the way. They notice the 13 kami did a ritual. A door replaces the center fountain. The details of the door look demonic and had 3 big skulls on the door. When the ritual ended they were order to follow 13 of them.

The person in charge was Kiva who holds 3 keys each corresponding to a skull. The door slid down. Kiva told eight of the warriors a saying. "

This gate way is to crescent valley, a place where the oni's live and coexist with hybrid humans; a place where the moon always shines bright like the sun.

"Now before we move on Tatsuga is the emperor of this place. However some factions are rebelling against him in secrecy."

"Wait then some Oni's are not going to kill us?" ask Rex.

"Yes." said Kiva.

"Enough talk let's move." said Schwartz. They set off in this unexplored dimension. Just when they enter they are stop by a dangerous slope leading to a Church.

"What are you crazy?" Thomas said. He notices the 13 kami slide down the slope hitting a part of the church glass. Thomas was surprised his party mates did the same. He followed their lead. When they landed in the Church they notice vampire's looking at them.

"Thomas these are my allies don't mind them." Kiva said. One of Kiva allies asks her something

"Madam what brings you here with these humans?"

"Our great-grandfather Tatsuga has taken their fellow friends down here." Kiva turns and walks away. In a few minutes Decade, Kiva's boyfriend opens the door to exit the church. It leads to the next faction area brawlers; where Oni's exchange items to one another.

"Kugen and Ryuki it's your guys turn to take lead."

"Okay not like we're fighting anyone anyway." The atmosphere change to a much more Vegas like. However the Church was much more gloomy dark.

Schwartz dozed off looking at the moon. Leonhardt goes to him and pulls back to the group.

"We'll be fighting in the next faction area. It will be fun." Kugen said.

"Kugen hurry and find the gate before the town folks think we are being suspicious. Ryuki said.

Just when Kugen saw it the agarest warriors found the gate.

"Let's not waste time before any thing gets worse." Vice said; when the Kami were walking towards them a tree branch block their way.

"Damn those oni hounds." said Wave. While this happen Thomas group had to defend against the hounds attacking them. Wave pulled out his giant ice blade to cut the flame tree branch. The 13 kami just sprint their way past the tree branch. When they got over the forest the gate closed behind them.

"Great now we are stuck here." said Duran. "Now were in the flame hound faction." said Hina.

"However we killed them accept one we know. But we must be careful. These flaming trees have a mind of their own." said Ura.

"Okay instead of talking freeze those damn trees said Violet.

Hina, Wave, and Ura impaled their weapons to the scorching ground. It caused the trees to stop moving; with due respect they had to travel 400 feet long to reach an altar. "My god my leg is trooping in pain." said Yuka.

"We're almost there guys. Just a few more steps." said Yagi. When they reach the alter they notice a 3 headed dog. It spoke

"Ah what are you 13 kami doing here? Anyhow there is a women not from here she wants to leave. By the way your grandfather Tatsuga almost killed her." this shock Leonhardt, Landaus, Thomas, Duran, and Rex. "Let's hurry up!" Yagi grabbed the woman named Ellis to the alter telaporter to send her back up the surface of the castle. Yagi then came back to the group.

The 3 headed dogs Cebu opened the big gate to the next faction; faction of the undead. 21 of them went on a large boat to go through a blood river filled with corpses swimming. Luna and Shima was in charge of dealing with this faction while everyone rest.

Luna pulled out her custom-made battle sniper. It shots 3 explosive bullets causing anyone to burn. Shima was holding on to a curve like blade that can cut trough any blade. All of a sudden a mob of dead samurai's jump out of the water. Shima side step all their attacks and kill them in one sweep turn. Luna on the other was struggling against dead soldiers shooting at a fair distance.

The soldiers are on flat land. Luna changed her weapon to a Hybrid assault rifle with a light machine gun magazine. Luna got out of her cover and fired all the dead soldiers with deadly precession. With the dead resting in peace they reach dry land.

"Everyone coast is clear." said Shima. But he notices his grandpa Hara. Shima runs towards him asking him something. When everyone catches up they are surprised to see their grandpa was alive. With the greetings aside Hara went forward to end Tatsuga's craze. He sprint trough all the remaining factions.

The faction they are heading to be pure chaos; where fiend like oni's makes illusions to kill their prey. Neo and Violet thought the best combo. When they enter the faction a mob of fiends charged towards them.

Neo pulled his time dagger and press a red switch to freeze time. Violet pulled out her distort sword to manipulate space around them. This caused the fiends to be frozen and broken apart in pieces. Everyone was still moving except the fiends. Everyone walk through the 100 feet hallway. When they reach the exit Neo and Violet put back their weapon. Time continue around them afterwards.

The fiends did not know what was next for them. They tried to move but were stuck midair. Violet flicks her 2 fingers this caused the fiends to drop to their demise burned in acidic water.

With the fiends gone the large door open up.

"This is the last faction before we can get rid of that tyrant Tatsuga" said Necro. This faction is torture despair, where higher up oni's make dealings with sadist humans for profit. But this time the warriors of agarest notice their male party members suffering.

Yuka grabbed them before anything gets worse.

Necro told them something "You idiots we will come up with a plan before we end up like them." With scars on their body and worn out attire they suffer in silents.

Necro put his plan to action. He activated his void gauntlets then shot a dark purple orb in the air of the city dome. The orb sucks in the city lights. When the lights went out Yuka freed the agarest warrior's allies. Yagi yet again sends them up to the surface world.

Necro then closed the palm of his hand. This made the orb in the city explode. The ruthless city folk were afraid who did that. Everyone went back to their usually things. But when it exploded the oni's were pulled in the magnetic field of the orb.

They were surprised to see the 13 kami again.

'You damn kami's free us now before we kill you.' With a sudden nod from Necro he freed them. But he knows their dark intention was to torture them.

Yuka pulled out her scythe from her sheath. Necro plunges the oni's in the pave bridge showing a pit to Tatsuga's faction. Necro and Yuka fought the oni's slicing them apart the bridge was filled with blood all over.

A total of 100 thousand oni's were killed. "That's the most oni's we slaughter guys." Yuka said.

"Seriously you guys owe us dinner tonight! Everyone ready to stop grandfathers Tatsuga reign?" said Yagi.

"Let it begin." said Grey. Everyone fell in the pit. When they hit the ground the environment was hazard to them. The faction is bringer nobles, where loyally oni's work under Tatsuga. Flames around the broken pavement arise. The path was block of by dark magic but they broke the seal. They walk up and notice that their young grandpa Hara was fighting Tatsuga minions. Hara killed them then turn around with a smile. But a sword impales his stomach. He gives his last words to his grandchildren.

"Although I'm dying please end this madman and reshape crescent valley. Go! There is not much time left he will burn the surface world."

He suddenly disappeared but they did not shed a tear. But press forward.

They walk up to Tatsuga's shrine.

Tatsuga greeted them. "Ah you fools came to kill me like you can kill me. Ha. But those fine women are in the shrine waiting for you agarest idiots."

All eight of them snap in frustration. "That it you are dead!" Yagi pulls out her swinging twin swords and fly's her grandfather up in the sky. All eight of them jump in the air.

Leonhardt impaled his sword and slash Tatsuga.

This made Leonhardt stay in a formation called five gates. Landaus jabs his sword to him. Thomas blasted arrows and pass through Tatsuga multiple times. Duran blasted a heat wave and slash Tatsuga in half. Rex enchanted his sword to become plasma cross blade. He then did the same as Leonhardt.

With five of them in the formation it was Vice, Schwartz, and, Grey turns. "Now our formation!" said Schwartz.

Their formation was called tri-slash. Vice, Schwartz, and Grey impaled their swords to Tatsuga.

Then the other 5 jump up and slash Tatsuga on all sides. When they executed the slash they were stabbed in the shoulders.

All eight of them were on the ground hopeless.

"Wow pathetic fools that did not do any damage to me. Tatsuga said.

"We cut you but you fell for our trap." Leonhardt said. "Nonsense those scratches you did on me will heal." Tatsuga said.

Tatsuga then grabbed Leonhardt by the neck.

Before Tatsuga can do more Kugen and Ryuki punch his check. Tatsuga fell on his side.

"You damn great grandchildren. I'll show you my demonic form!" A black fog covers his whole body. The fog transformed his whole body. His whole body was covered in a dark steel armor covering his face, wings on his back and a snake's tail. His sword became a broad sword. He calls it the crazy blood blade.

The only person that knows his weakness is Yagi. "Now come and face me."

"Everyone ready just do what we did during our training" said Yagi.

Kugen and Ryuki ran towards Tatsuga, they then split up. Kugen took the left. Ryuki took the right.

Tatsuga was about to fly until Kugen and Ryuki pulled his wings of, they then uppercut him up.

Hina, Wave, and Ura slash Tatsuga's shoulder pads with their ice weapons. They then plunged him to the ground. Tatsuga got up and slash Luna's right shoulder.

Little did Tatsuga know? Luna places a C4 on Tatsuga chest. Luna then fires all her bullets to that C4. Shima then got a chance to hit Tatsuga's back. Luna then throws a healing grenade on her location.

Kiva and Decade jab their blade to Tatsuga's foot and removed it.

Neo and Violet cut his helmet apart showing his face.

Necro, Yuka, and Yagi finish Tatsuga off. Necro punch Tatsuga in the knees. Then Tatsuga stab's Yuka right arm. Yuka droped her scythe but told her twin sister Yagi to end it. Yuka moved to Luna's location.

Yagi uses the scythe to stiff up Tatsuga shoulders. Yagi then gave her sister back her scythe. Yagi then spirals her rope swords around and slash Tatsuga's knee. All 13 of them then circle around Tatsuga.

Kugen then ask the helpless Tatsuga something. "I wonder why you became a power hunger leader. But before you are sent to your tomb any last words?"

Tatsuga replies back. "There is a greater evil than me. However crescent valley will be able to see sunlight yet again."

They perform a ritual to transport Tatsuga to his tomb and stay in an eternal sleep. With the ritual near its end Tatsuga shed a tear. When the ritual ended the environment changed.

The sun replaces the moon. The trees were green not burn. The stairways became normal. Just like the surface world. Luna then throws a healing grenade to the agarest warriors on the ground laying there. With the healing process going on Yagi open the shrine door and free the ladies that were tied up. Yagi then sends all of them back to the surface world.

Kiva then locks the gate to crescent valley. It then hides underground. The fountain replaces it. Luna then used a grenade to teleport the agarest group to their dimension.

With a big sigh from Necro he had to cook food. It took them an hour in crescent valley but in the surface world it was actually 11 hours has pass; with them so tired Yagi closed the castle gates. Everyone stayed inside by the kitchen.

With them waiting we move to the RWBY team.

Everything felt awkward in the kisaragi house.

Ruby introduces her sister and friends to Dusk family.

Jin was not surprised that's his son like Ruby.

Noel on the other hand was happy in tears. "Son your girlfriend is so cute." This made Ruby blush.

"Uh dad can we eat now I'm starving. Okay Dusk let's eat."

With the chatter done everyone ate.

After they ate Jin allowed the RWBY team to live in this house.

Saya then came in with a letter. Giving it to Dusk but was in his room. Dusk reads the letter and shed a tear. "Wow… Okay."

Ruby then jump in front of Dusk. Weiss, Blake, and Yang had the other half of the room.

"Little sis don't go overboard with Dusk. Yang said.

Dusk replies. "Don't worry Yang, Ruby is nice." The clock reached 9:30 P.M. That is Dusk usual curfew.

Dusk then turn off the lights to sleep. But surprisingly his holding on to Ruby's hand still. Dusk was embarrassed that he is close to Ruby's face. Dusk then warp his right arm around Ruby.

With everyone sleeping a person floats in the sky and talks to them self;

"In due time I'll end this world in bloody despair." That person started laughing evilly afterwards and left the place to the unknown.

A/N : Next chapter "The sadist O.C vs. Hero O.C" -_- I'm tired folks happy labor day.
