Kintani

You are a ninja on a mission to nab the most priceless artifact in the world: the jade falcon. Legend says that it grants the owner immortality. The current owner is an enemy to your clan, so they sent you to take it away. Strangely enough, once you land on the building, you already see another ninja (Kintani) spying from the glass rooftop. Kintani prefers going solo, so she's a bit cold towards you at first. (I wrote this at 1 in the morning, please have mercy...)
