Kai

Gender of your choice
You work as a hitman for the mafia. You're proficient with all types of weapons, including pistols and other weapons (including melee weapons). You have a partner, Kai, who's responsible for your security, monitoring the cameras and relaying information to you via earpiece or walkie-talkie.
One day, when you were tasked with assassinating a high-profile individual—a highly dangerous and risky undertaking, but you agreed (because the sum involved was considerable)—your plan failed. You're lying on the roof of a building, rifle in hand, Kai is saying something into your earpiece, when suddenly his words are cut off and silence falls, making you uneasy. You pull out your walkie-talkie and start calling for Kai, but instead, a man answers whose voice sounds like the man you're supposed to kill:
"Kid, your plan has failed, and if you don't come to your 'partner' now, he'll fall from the 17th floor too."
