"Melanie, who is this girl?..."

"I don't know, Miltia, but we should teach her a lesson."

- Melanie

Melanie & Miltia (Miltiades) Malachite are pair of black-haired twins that Yang encounters and fights in a nightclub during the Yellow trailer.The twin sisters are seen working for Junior and they fight Yang.

Appearance
Melanie is a teenage girl with long black hair and green eyes, highlighted by heavy cyan makeup. She wears a white, strapless dress with cyan lining. Her accessories include a large white flower hairpin above her left ear, a white furry scarf, a silver pad with cyan and red feathers on her left shoulder, white gloves, a bow on the top-most part of her bodice, a silver chained belt, cyan wings on the lower back, and long white boots with blades at the heels.

Miltia is a teenage girl with short black hair and green eyes. She wears a red, strapless dress with black lining. Her accessories include large red and white feathers above her left ear, black fur hanging off her shoulders and held at the front by a dark gray chain, red gloves, a black bow tied around her waist, and long red boots. Her dress seems to be made out of, or is decorated with, newspaper articles with the heading "A New York la pop art di Alborghetti."

Personality
Though Melanie has only one line in the trailer, it can be assumed that Melanie is a strong-willed, confident girl. Melanie stands and acts in an arrogant manner, even after seeing Yang's fighting abilities. As well, she directly shows that she was displeased when Junior told her and Miltia to stay away when he wanted to talk with Yang.

Though Miltia has only one line in the trailer, it can be assumed that Miltia is a generally shy, quiet girl. She stands in a polite manner and lowers her head a bit, which contrasts with Melanie's attitude. She also followed Junior's order easily, the one telling her to move away, while her sister showed a sign of stubbornness.

Abilities
Melanie fights primarily with kicks, using the blades at her heels as her weapons. She possesses an above-average strength, agility, and skills, being able to do fast shifting and evasive flips to move around in combat. She can even parry and cut Ember Celica's shells with her kicks, at both close range and long range.

When Melanie fights alongside Miltia, she forms a great combination with her sister, using flanking, distraction, and swift kicks to assault Yang and create an opening for Miltia to attack. She also helps her sister while attacking, as seen at one point that she sweeps Yang's leg to prevent Ember Celica from aiming at Miltia. The twins prove to be a match for Yang, and manage to knock her down once. Even without Miltia, Melanie is shown to be a very skilled fighter on her own, being able to hold her ground against Yang in close combat for a short time.

Miltia fights using a pair of red and black claws. She possesses an above-average strength, agility and skills, being able to do fast shifting, evasive flips and even deflecting some of Ember Celica's shells.

When teaming up with Melanie, the two can attack in unison and are able to threaten more powerful fighters, such as Yang. It seems that Miltia is a good opportunist, knowing when she should engage with an opening created by her sister or follow with her sister's assault.
