I know not where I come from or my real name. I merely picked "Yin" to represent the shadows and darkness, contrasting those in the light. I was adopted by the Assassin guild and tested out for my skills. Turns out, I was the perfect assassin, mastering every challenge with strong intuition and quick learning, as if I had been born for this. Dance across the waterfall. Dodge the thin strings laid with triggers of poison. Charm the noble and steal his money. They were all not an issue. But then the final test had arrived.

Many assassins were forced to turn away, unable to ever kill their parents who had raised them or their lovers. However, I was different. I felt very little emotion to most people, and thought long and hard about the challenge. How can you kill your most loved one if you love no one?

I looked towards the sky and looked for the person who had brought me the most warmth. As I saw the shining light, the answer was simple. I waited for night to fall, as I steeled my blade, striking only with the simplest of weapons. Tricks and fancy traps wouldn't work against my opponent this time. I donned my mask and uniform with the symbol representing the Guild's prowess.

He sat there in the calm with his legs crossed and closed eyes. Even in this state, I knew this was going to be difficult. One second. Two seconds. Three. I took a deep breath and rushed out behind a pillar, as he opened his eyes, catching my blade with his bare hands. "Who dares?!" He glared at me, parrying each blow and swing with practice, like he had done thousands of times before. As he glared at my form and uniform, our turning and tactics ever so familiar, he recognized me. "Why are you...?" He raised an eyebrow, daring me to finish the question.

But it took all of my focus just to equal him even with a knife in my hand. The dance continued, as he landed a bruise, knocking me backwards, still in a bit superior position. I barely held on to my weapon, brandishing it again. In a quick charge, I landed a small nick, only to get my body twisted around, as he kicked me across the room, the knife landing beside me. "Huff.... the final... test." I finally said, catching my breath.

He looked at me in disbelief. "You have got to be kidding me." In his hesitance, he lowers his fist, as I stand and run, barrage him with a series of blows, finally dealing some more damage. He recovers, countering the best he could, but seems to be struggling with the decision. Minutes pass with our deadlocked battle as we finally tire. Far too long of a battle to be an "assassination". I was disappointed... my skills still weren't good enough. However, he shakes his head, also seeming to agree with me. "This is... partially our fault, isn't it. The guild was bound to have connections in between its members... and things never made any sense. There must be something else behind its final test... I shall make you a deal. I will fake my death and you shall graduate. See to it that you discover the secrets behind it. I never questioned it until now. You have opened my eyes... Yin."

I breathe a sigh of relief... seems like I didn't have to keep fighting. "Oh, and an advice? You missed the left knee counter in that split second when I used the right hook." He lightly smirks at me, leaving the room.

"Yes, Sensei." I call his proper name, bowing one last time. My real test would begin soon.... I had best sharpen my skills more.
