Hey Koshikaden here. If you read my other stories, then you would not be expecting me of writing a fanfiction of RWBY. As for why, well, a friend of mine got me into the series and I'm up to vol. 5 but missing vol 6. I'm taking a break from my digimon and naruto stories because I have a magraine level writer's block and some of my recent bits I didn't like. Don't worry I will be writing till I complete them anyway. I read plenty of fics of rwby, and all or most was naruto crossovers.

I have made a darker twin of my main player ace for this fic because I will be doing a theme and I have chosen one of the canon players to be his opposite. I will be changing some parts, but adding another in the game. For the second newcomer, I made her appearance off of the auramancer card in magic the gathering, but made my changes to her like making that into a transformation and a part of her semblance.

For now, I will leave you a trailer of my first character and a dark remake of my original star.

Disclaimer: I don't own RWBY, that is RoosterTeeth, or the Auramancer card by the creator(s) of Magic: The Gathering. I do own my own ideas, characters, and this fic.

Now on with the trailer


In a dimly light room with only small lamps and candles, there were screams of pain from a woman giving birth. The husband was doing his job while a close friend of his was delivering their child. After agonizing minutes of screaming, the baby was a boy with his eyes close and a curl of black hair on his head. Hearing the baby scream, they liked it's sound, but decided on a name.

"What should we call him?" The husband asked looking at his wife.

"Yin Kamen, but call him ace. I think he looks like he is a smart one." She said and he nodded.

Soon the crying stopped and they looked to see him trying to open his eyes.

'What color will they be?' The parents thought before his eyes opened and they gasped seeing them.

Slow down and watch out speeder

Ice on the road

You may live in the Light of the Sun,

but I'm the darkside of the moon.

Super Saiyan? Why go yellow when I can go blue

I see the army that you brought

And I raise you grimm and darkness

You think you are the fastest?

Bitch please I'm the Cold Breath of Death

Late at night was a kid in his teens walking around in a town wearing a black hooded cloak to cover him up. In the background far away from him, are four girls watching him from different locations. Two are standing on roofs of small buildings one girl standing was wearing black with a bow on her head holding a black sheathed katana be her side (Blake) and the other a few feet away from her is dressed in yellow, brown, and some black with a scarf around her neck bouncing on her heels (Yang). The other two are not as high as those two, but they have their eyes on him. The third girl wearing a red hooded cloak to cover herself standing under a street lamp holding a small scythe in her arms (Ruby) and the last one dressed in white is sitting in a teashop drinking a cup of tea near a window to see her friends and him (Weiss).

Two sword sheaths are on his back crossed like an X with the hilts facing each other. The hilts are gun stylized and the chambers are filled with dust crystals. Black fingerless gloves on his hands, but this gloves have a glyph made for him to use etched on his right glove in gold dust while the left glove has a red thundercloud etched in dust. He has gold bands on his wrists and a charm necklace/locket hidden under his cloak around his neck. The four girls are watching him from their spots and each one is showing a different emotion; red was worried (Ruby), black believed in him (Blake), yellow was confident in his abilities since she sparred with him (Yang), and white was proud of him for taking his studies with her seriously (Weiss).

At his house, his parents more likely his mother was crying as his father was consoling her. His baby sister is looking out from the window in her room watching for him.

'Come back home, big brother' Aki, yin's little sister thought watching for her big brother.

Ice ice baby, not nice ice baby

Feeling sorry for you small fire prick

Cause I have two words for you:

Liquid Nitrogen.

Freeze with just a touch

An army more deadly than a demon lord

Like frostbite, I will freeze your pale ass to death

Monsters you say? I dont know Hate and Anger?

Smirking as he had a feeling that his little sister is watching him, he stopped walking to see a young man around his age may be a bit older with a derby hat and cane (Roman) standing a good distance away from him. Snapping his fingers, the person sent a pack of pitch-black wolves coming out of the darkness of night (beowolves). Yin lifts up his head and reveals his eyes, a blood red fox eye and a gold wolf eye as both are slitted like a dragon's eyes, making him part of the faunus race while his skin is a light tan. The person frowned seeing the eyes of a faunus in front of him as yin lazily grabs one of his gun blades with his eyes narrowing. The black wolves charged without needing an order, but yin jumped back with a backflip and sliced the black wolf that attacked him first in half. Yin jumps out of the way from claw swipes or a pair of teeth with his fast reaction speed, but strikes with great strength. Yin uses aura in small bursts to use his reaction speed and use aura to boost his attack power so it would look like he is dancing around the attacks.

The person's frown deepened as the black wolves were killed off by yin who was holding his gun blade with one hand against his shoulder. The person sent more black wolves, but kept one back to get pass yin and go after the girl in red. All four girls were off guard by the wolf charged after her/their friend and the wolf managed to nick her arm before it was turned to dust by yin using a fire dust crystal he had in one of the slots in the chamber of his pistol-revolver gun blade. Yin was feeling his rage building so his aura turned out to be dark red with a black outline surrounding his body.

"Big mistake." Yin said before holding his hand out and released a dark reddish black shockwave killing the black wolves that were surrounding him.

Do I need to choke a bitch?

I am the ambassador of Anger

And the Herald of Hate

Humans and faunus fighting like cats and dogs

Never seeing the holy common ground

Only the dammed differences

The grimm don't discriminate; only annihilate

"Hmm." The person said before slamming his cane down just as large black bears appeared charging at yin (Ursai).

Unknowing to yin, a black magatama with a white dot appears on his right hand under the glyph glove and it started to glow. His eyes changed to glowing ice blue as dark blue ice crystals started to form around him and he started to growl while his eyes narrowed. The temperature started to drop around yin before pulling his second gun blade from its sheath and fight off the black bears. Yin danced around the bears using his aura to boost his reaction speed and attack power as his semblance seems to be ice related. The gun blade with the dark red blade changed to glowing ice blue with it being charged with ice dust in the chamber. The other gun blade with the black blade has shadow glow to it, but it feels darker. Yin killed the bears effectively and efficiently surprising the girls especially the one in white drinking her tea.

Black like dead roses

Bright Gold pales to compare to Dark Silver

White can be a winter wonderland

However, I can turn it into a frozen death trap

Times through the ages and generations

Fights both with and against the light

Now I have an prentender

Time for the real grim master to reamerge

The person was mildly surprised as yin sheathed his gun blades, but he was feeling like getting blood for his best friend getting hurt. The person pressed down on the top of his cane to hear another click before something large jumped through the air and landed with a large thud. The large mass has red lines, but moves like a spider (Spider droid). Yin knew it was a robotic spider, but much harder to take down than the grimm he already faced. From working on his boots and gun blades, yin knew about how dense different metals can be. Feeling like he is going to have a challenge, yin smiled before cracking his knuckles triggering his gold bands forming into gold gauntlets that end at his elbows and the gauntlet over his right hand as a deep dark purple fleur-de-lis on the band. The gauntlets has pistons to give his punches more force and uses special rockets custom made, but they help him with landing combustion punches while his boots have parts in the bottom to seem like they are like rocket jet boots. He has two small dust crystals in each gauntlet so his punches are more explosive with the pistons and special made rockets.

The girl in black flinched remembering going up against one of those things and felt like she should help him, but something about him made her stay with her friends. The spider bot was at long range so it targeted yin before charging the cannons on its arms. Clicking his boots, he got a boost of speed as he started running towards the spider bot and building momentum for his explosive punches. Once he got close enough, the spider bot's arm cannons fully charged and fired a blast at him. It seemed yin got too close when the blast made contact, but he jumped at the last second. Upon landing, he is in front of the spider bot and his gauntlets clicked once to ready the rockets. Using the momentum, he landed an explosive right on the front left leg and it cracked a little. He landed a few more strikes on that leg and jumped back before the spider bot could beat him away with a swing of an arm. The leg he had worked over showed more damage, but the metal was denser than he thought.

"Fire, wind, darkness, and ice." Yin said triggering the dust crystals in his gauntlets to while his eyes glowed ice blue.

The spider bot fired beams from its shoulder cannons at him, but he dodged the shots and landed six strikes breaking that cracked leg. He fired two mini rockets into the cannons on the spider bot's arms before using the rest of his rockets on the other front leg. Jumping back after seeing a crack forming on the leg, he jumped high into the air and ejected the empty shells before popping in two full clips of his special mini rockets. The spider bot following him, but it's shots were still missing him and yin ready the pistons as the spider bot merged the four cannons into one large cannon. Yin made his gauntlets glow red to give them a boost and he clicked his boots for more airtime before changing his angle. Clicking his boots again, this propelled him like a rocket at the spider bot.

Said spider bot charged its mega cannon at him with the intent to kill him, but said person stopped the beam. Yin started to push the beam back with rocket punches and use his boots to push him further, but only sparingly. He used the pistons to push the beam back before using his boots to help him bypass the beam and jet forward homing in on the spider bot. Within a minute, yin turned into a black ball with a blue tail only his gauntlets were red. Before it could charge another shot at yin, he crashed into the bot and made a hole in its chest, but jumped to its head and used all of his rockets to destroy it. It disintegrated into nothing and yin put another clip of both rockets into his gauntlets. The girls moved closer to yin, but stayed up on the rooftops and only a few feet away. Having his gauntlets fold back into their sealed form, the person is about to slam his cane again before there was a bang of a gun being fired. The sound came from yin holding an older looking gun blade with a smoking barrel. The shot dented the cane and scratched it as yin prepared another shot. The gun is a pump action double barrel buckshot.

The person clicked a button in the top of his cane. A rumble occurred before a dark gray pair of giant leg armor and boots dropped to the ground. Other pieces of armor started to drop to the ground till it formed a giant full set of dark gray armor and a blade drop to its side (giant armor). Yin glanced to the girls and smiled before charging energy into the glyph on his glove. His shadow turned darker before splitting into five true shadow clones. Those five made another five clones and clones kept being made until there were twenty-five clones formed. The clones surrounded the giant suit of armor and yin was using ice dust power. The clones jumped into the air before using ice dust to make platforms of ice for them to stand on. Each set or ring of clones will use dust bullets, aura shockwaves, or dust/aura energy waves fired from the blades of the gun blades. The giant armor was being battered around like a pinball and small dents were being formed while small cracks formed in the steel of blade from blocking what attacks it could.

The girls dressed in dressed in black and white were surprised to see him combine the lessons they taught him by using darkness of his avatar power to form the clones and give them ice dust through the glyph on his glove. The dents and cracks were growing from the ongoing attacks in the giant armor and its sword. Yin is charging his gun blades with ice dust, darkness avatar powers, and aura, but the glyph appeared on his other glove. His blades were glows both ice blue and a deep dark ocean blue with a bright red outline because of the darkness, ice dust, and aura being mixed due to the glyph. Yin's eyes started to switch back to their normal color and he was feeling the drain of his aura from using it too much. Once the cracks in the sword of the giant armor formed one long crack, yin jumped using his boots and landing a strike on the blade making it shatter completely. The blades are still glowing as yin landed on an ice platform before making an X energy attack and boost it with a blast from his third gun blade. The giant armor is destroyed by the attack and five clones faded into five clones due to drain of energy.

The person smiled before lifting up his cane and fired a shot at yin, which it look like a firework blast. Yin jumped out of the way and fired another shot at him denting the cane more before the blast hit the spot where he was and made a smokescreen. Yin jumped away from the smoke to see the person gone so he sighed as he let his eyes return to their normal state and the black magatama faded away without being seen. The girls ran over to him as he was made the older gun blade fold back into a spyglass. They hold on to him so he wouldn't fall to the ground as he was near death from over using his semblance, aura, and not being used to his avatar powers, but he passed out as they took him home.

(Fade to black) [Song ends, but music slows]

The last shot of the trailer is an evil laugh and a pair of red eyes from a demonic looking grim before everything fades completely black and the laugh echoes.

trailer ends *music end*


Now, let me explain. I wrote that song out on my own while listening to yang's I Burn on repeat so much. I'm not a songwriter nor am I good at it, but I did it because I made yin as an ace variant. I made him to be in the RWBYverse and change that series with my own changes.
