Something Is Lost
Zhong Xinyi is...well it's rather hard to put into words, you could go with a number of things to describe them. He is nonhuman, a murderer, some might call him a vigilante, an informant, or a genius at stealth.
However one chooses to address them, it matters not, because, in this instance, he is but one person who has gotten themself into a situation he doesn't want to be in.
Xinyi stumbles into a problem after one of his jobs, two opposing forces pulling him into their business almost completely unprompted, thrusting problems his way left and right and forcing him to make choices he'd rather not.
