A/N: Basically this is RWBY x Naruto crossover fanfic. I will be introducing four OCS that will join the RWBY timeline.Vale, home to the powerful acadamies known in Remnant, Beacon. The shattered moon was shining brightly at the midnight sky.

Ruby Rose, The leader of Team RWBY, was wondering around the Beacon Academy when she saw a figure at the Beacon Cliff. She approached it.

"Uhm... Hello?" Ruby asked the figure. The figure had a black coat with short sleeves, with red flames at the bottom of the coat itself and the sleeves. It also had the kanji for Assassin of the Shadows. It had black hair cut short and black jeans, black shoes with red flames at the bottom.

The figure turned to face her, It had a kitsune mask, with black flames at the chin and near the eyes. Under the black coat, He had a bloody red and high collar long sleeve.

"Yes?" the figure asked. It sounded very deep and masculine. his bloody red eyes that had three tomoes, circling the black dot at the middle.

Ruby gulped. "W-What are y-you doing h-here s-sir?" She stuttered out. She was shivering in fright. her hand was at the handle of Crescent Rose.

The figure laughed. "Didn't you know? I am a student in this school. First year to be exact." He said as he took his mask off, showing his face.

(He looks like Kisaragi Shintaro.)

He was smiling. "See you around." He said as he burst into black, glowing flames. When it died down, He was no longer seen.

She shook her head. 'Who was that?' She thought. She went back to her dorm to sleep.

(Afternoon, Glynda's Room)

Ruby was with her team as Glynda was picking two people to spar. "Hmm.. Cardin Winchester." She said as he rose up. "Who will you spar?" She asked him, Ruby looked at Jaune, who was shivering in fright. "That dude over there with a mask." He pointed at the same person she saw last night. "Very well. Shadow Nachisenki of Team SYNK(Silk)?" Glynda asked Shadow, the person with a mask, to which he nodded. He burst into black flames and reappeared at the stage in black flames. Fully worn his clothes last night without his mask on. Cardin went down with his battle armor, Mace in hand.

"Rules of the match: The match will be over when one has his aura depleted, unconscious or unable to battle. Dont be afraid to go all out. Ready?" Glynda told the two. Cardin scoffed and nodded. Shadow did a slight nod.

"Fight!" Glynda shouted as Cardin charged at Shadow, doing his battlecry. Shadow narrowed his eyes, looking at Cardin as he charged. "Goodbye!" Cardin shouted as he brought down his mace at his head. Everyone looked away except Pyrrha, Glynda, Ruby and the rest of her team.

They heard metal clashing against metal. The rest who turned away looked at the match again and gasped.

Shadow, who brought out his weapon, which was a katana that had the height of 5 foot, and 3 inches wide. The weapon was colored black. The weapon seemed to glow dark red as he smirked, as the katana he held was cutting deep at the mace, looking like he was using a chainsaw cutting wood.

Shadow cut Cardin's mace in half as he dashed behind him, leaving a black trail as he kicked his back, making him fly to the wall. Cardin grunted as his back hit the wall. His aura lowered to 96 percent. He rushed at Shadow, intent to punch him in the face when Shadow rose his free arm, which was the left arm, as spears that looked like Pyrrha's, as they embed themselves at Cardin's armor like it was nothing.

Cardin stopped at his tracks and fell down in one knee. Shadow looked at his aura, Which was 98 percent. He looked at Cardin's. It read 56 percent. He smiled as he shifted his katana into a small SMG and aimed at Cardin. "Yield, Cardin." Cardin grunted. "NO!" He shouted as Shadow sighed, pressed the trigger and shot rockets burned with black glowing flames at Cardin. exploding in contact. He looked at Cardin's aura as it went to 3 percent. He smiled.

"Cardin is unable, unconscious and his aura has been depleted. The winner is Shadow Nachisenki of Team SYNK. Ca-" Glynda was cut off when Shadow teleported Cardin to the infirmary and looked at Glynda. "Cardin is in the infirmary Proffessor." He bowed as he burst to black flames once more and returned to his spot.

Blake looked at his back, Making out what the kanji meant. 'Assassin of the Shadows?' She thought.
