I only own my OC.

Over the course of the day, somehow, Yin's encounter with Winter Schnee was known throughout the school. Which Yin didn't quite understand until Weiss came to get him, after helping to wake Winter.

"Winter's challenged you to a fight. In the courtyard after our final class. Are you sure you want to fight her?"

Yin nodded.

"I am confident in my abilities, and I know better to get cocky."

Weiss whimpered. She knew how skilled Yin was, but genuinely feared for his well being. At the end of the day, Yin walked out to what a lot of people thought was going to be his death. However, Yin had a different idea. Approaching Winter with a calm and quiet confidence as their audience watched. Almost immediately there was the clashing of blades. Yin parrying each and every blow Winter gave, making them miss him entirely. As Winter got angrier, Yin seemed to blank out more and more. His movements slowly becoming more fluid until all of a sudden, just as Winter thought she'd memorized his pattern, Yin exploded into action. His movements with his katanas becoming quick and ruthless, disarming Winter and making it so that they were both unarmed. Thinking that they had ended in a stalemate, was completely unprepared for Yin to lunge for her, not even bothering to activate his semblance as he ducked under her guard, and in true boxing style delivered several quick punches to her midsection. Winter resorting to summoning a boarbatusk in an attempt to run him down. Not expecting him to simply jump over the summon and ride on its back for a second before landing in front of her again/

"I'm not wasting my semblance on you."

Yin said calmly. He preferred to be at a distance from his opponent, but he was trained in close combat. Mostly because his mother had insisted bandits be prepared for every eventuality.

"Why not? Is it possible you don't even have one?"

Yin's eyes went from lilac to a deep crimson red, his pupils changing to vertical, snake like slits. After harshly kicking Winter back a few feet, he burst into black flames. The fire giving everyone around him a sense of pending doom and despair, while the chill coming from the flames made everyone briefly wonder if that was what death felt like. A few moments later, Yin emerged from the flames as a fairly large dragon. He was tall, with glowing red eyes. He was muscular, covered in black scales with a long and powerful tail, his nails having grown and sharpened into claws and his hair having changed into a line of red fire going down his back to the tip of his tail. In his mouth were sharp, dangerous, bright white fangs, and from between his grit teeth was even more fire. With a roar, Yin's eyes showed an emotion that was truly rare to him. Rage. Pure and unfiltered rage. His roar echoed in the ears of his onlookers. The sound making everyone feel small and insignificant in his presence.

The black fire he'd used to transform formed around his hands, now claws, and he lunged. Winter being too in awe of his transformation, and how his uncontrolled aura made those around him feel nothing but fear, was barely able to react when the now draconic Yin slashed at her with flaming claws. His massive wings even being used as weapons and shields as he batted at her with them. Any time he moved his tail not only being used as a counterbalance, but as a whip. The flames still burning bright on his body despite his movements.

Ozpin was amazed at the boy's semblance and skill as he fought. Though he realized fairly quickly what was going on.

"Dust, he's playing with her!"

Ozpin said in shock. Glynda was surprised by Ozpin's statement, until in a single quick movement, Yin had swirled around and grabbed Winter with his tail. Using the momentum gained from his sudden movement to throw her into the fountain in the middle of the courtyard. That just seemed to make Winter angry and the two of them engaged again. Yin's tail lashing around him to be used as effectively, a third hand. Winter was starting to feel outnumbered, not even realizing that the draconic form Yin had adopted wasn't even his semblance. And that his semblance was slowly eating away at her aura to power himself. Charging up his true semblance, which was really the long ranged version of his sister's semblance. His eyes glowing brighter as he finally jumped back and opened his mouth. A fireball of epic proportions growing in his mouth before he launched it with a stream of fire following it. The fireball growing to the point that it became clear Winter couldn't outrun it. However, she did raise a shield glyph over herself, that was promptly obliterated by the incoming fireball that sent her flying, doing incredible damage that only the small bit of her aura Yin had chosen to leave intact making the attack survivable.

Maintaining his calm demeanor, he thought temporarily of his semblance. He could use it in his human form like Yang, but it still came out as red fire surrounding his body before he channeled the blast through his sword, or, if he was unarmed at the moment, his hands. Either way, if he got angry, that's when the real fun started.

"I do believe it is rather clear Mr. Branwen is the victor of this fight."

Jacques said nothing, and the rest of the students in the schoolyard seemed frozen between shock in the ruthlessness the normally calm and collected teen had shown and in awe at the pure power displayed.

Yin returned to his human form and looked over at Cardin, who looked very much afraid of Yin. A result of his aura still being uncontained. While his sister represented the light, Yin himself represented the very depths of darkness. His aura running rampant gave people a chill.

The chill they couldn't get rid of, no matter how hard they tried. The dread and fear that they were about to meet their deaths. Slowly draining all hope they had for the future. Some argued that that was his semblance, and through honing it he could use his Dark Karma power as his mother called it.

"I'm still not angry Cardin. And what did I tell you earlier?"

Cardin and his team were already backing away. Yin's aura still flaring around him to the point it could be felt in the air by everyone present. Yin's intense control being the only reason it wasn't actually visible around him.

"That we wouldn't like you when you were angry."

Yin smiled, returning his teeth to the cruelly sharp fangs of the dragon.

"And don't you forget it."
