Темнее черного

Kastenin, Gai, and Kiko take Yin back to her home town, meanwhile Hei is given the order to kill Yin and is given her location. Getting to Yin is not going to be that easy since th contractors from before are still after Yin and have their own method to finding her. The race is on once more, but this time Hei must make the choice on whether or not to kill Yin. Will he kill her or will the option be taken from him?
