For those who don't know (most of you will) the Malachite sisters are the twins who fought Yang in the "Yellow" trailer. The two girls are Melanie and Miltiades. Very little is known about the two, however, Melanie is shown to be more confidant as well as arrogant and cocky. Miltia seems to be less confident and more quiet, often seen standing in a polite stance with her hands in front and her head lowered slightly. Melanie can be seen as stubborn. This is shown when Junior waved the girls away and Melanie visually shows her displeasure while Miltia easily and calmly leaves. Anyone have anything else to add? I wanted to put this thread up because I think these two may turn up again in volume 2.
