Miltia is one of Junior Xiong's henchmen, possibly acting as one of his bodyguards.
Melanie is Miltia's twin sister. They share a close relationship and are always seen with each other. In battle, they sync their movements and strikes to creating a flowing tag team combo.
Junior is Miltia's superior. It is implied that Miltia, along with Melanie, is Junior's bodyguard, as she is seen to follow him. Unlike Melanie, Miltia has no problems following Junior's orders. They both defend his club when Junior is attacked by Yang Xiao Long.
Miltia fights and is defeated by Yang in the "Yellow" Trailer.
