I don't own Assassin's Creed or Yu-Gi-Oh!, blahblahblah. No future disclaimers, LET'S BEGIN!

Chapter 1: The New Kid at School! The Silent Girl with Secrets!

Yuma was walking home from school, with a look on his face of curiosity and determination. His odd extraterrestrial partner, Astral, was following him. After some time, Astral decided to ask Yuma what on Earth was making him have such an expression.

"Yuma, what is bothering you?" He asked.

"I hear there's a new kid coming tomorrow, all the way from Italy. I have so many questions though. Does she duel? Why is she here? Is she friendly? What's her family like? Will she talk to someone like me? Does she know about the Numbers? Just exactly who is she?" Yuma replied, spouting out so many questions that it seemed he was about ready to interrogate this new girl.

"We can only wait until tomorrow, Yuma." Astral said, knowing Yuma's impatient and hyperactive nature. Yuma grunted. He knew the alien was right, but didn't want to admit it. Yuma got home, and went into his room to relax. School had been stressful-four tests in a row! His brain needed to relax. However, he had no idea that he was going to wade into a dangerous water-a water that he would never be able to get out of.

Elsewhere...

"Everything is going well, Desmond. I have already killed most of Abstergo. My life will be much easier. How is everything in Italy?"

"Well, Amy. We're kickin' ass. I gotta go and do my job-live others' lives in the Animus so I can get even better at kickin' ass. Bye." Desmond replied, hanging up. The girl smiled, and looked at her Assassin ID.

She looked at the burn mark on her right ring finger she had received upon becoming a Master Assassin. It was part of the ritual. Her beautiful, white skin looked perfect. She sighed-the only thing she didn't like about herself was her heterochromia-her left eye had turned red because of an accident on an assassination mission, but her right eye was a normal blue color. Her hair was midnight black, long, and straight.

She pulled out her black Assassin robes and her weapons. She changed into the Assassin's robes swiftly, slid on her boots, and put on her belt. She slid her sword into its sheath, put her Dueling supplies into her bag, and attached her bow and arrow quiver (full of poison arrows) to her back. She slid her regular hidden blade onto her left arm, and her hookblade onto her right arm.

"It's time to begin. No one will stand in my way, Duelist or not. I shed no mercy...I am an Assassin." She muttered. She scaled the wall with ease, and began leaping from rooftop to rooftop with even greater ease.
