Mylene

Mylene (ミレーヌ, Mirenu) was the Servant of the Cold Emperor, Lyon.

Personality
According to Paul Gekko, Mylene is very sadistic and calm to the point where she is willing to do whatever it takes to get herself out of a 'sticky situation'.

Abilities

 * Mylene's record suggests she is a good brawler, as she won half of all her battles that have been seen. She is considered the third strongest of the Kuro Akatsuki.

Gauntlet
Gauntlet is a large bracelet-like device developed by the Hylians. She is also known to wear a Gauntlet. The device is operated by pressing a button on the tip, and then the compartment that cards go into will open when summoning the Icy Orochi.

Background
Very little is known about Mylene is that her family was a victim to the the Ten Tails and that sometime later, she joined Kuro Akatsuki and started working as a Shinobi who serves the Cold Emperor.
