"[i]Nicole Malice obtained a new servant thanks to her sister, [[Persenachia]]. Misty still doesn't pay her much attention, but is secretly astonished at her growth.[/i]"
 -Knight's in-game description.

"[i]Perphaps an imitation of [[Persenachia]], Nicole has contracted with "Yomi", an ART-type servant. Apparently she had to travel quite some distance to obtain it.[/i]"
 -Yasha's in-game description.

A [[Mecha Musume]] from the game [[Cosmic Break]], Nicole Malice is a white-haired young necromancer who, judging by her descriptions, has a somewhat arrogant personality that diminishes as she grows. In-game, the original Malice can be obtained through the shop for 80000 UC or 80 RT while her red-haired variation, whose parts can't be changed, can be obtained through the Super UC Gara and her other variations are only obtainable through the RT Garapon system. 

Nicole Malice was [[Misty Hollow]]'s self-proclaimed rival ever since she started her career in the Cosmic Ark, although Misty supposedly never acknowledged Nicole as her equal during that time. While Nicole's descriptions directly mention Misty, none of Misty's descriptions mention her at all, however Knight's description states that Misty was astonished at her growth, while at the same time it doesn't make any antagonizing remarks at her on Nicole's part. This hints both at Malice's maturation and shows Misty's acknowledgement of her as an actual fighter.

During Nicole's early career as a Cosmic Hero, she relied on her first servant, Dead Eye, to deal significant damage to her opponents while absorbing their energy with her Soul Rod, a homing sub-weapon that replenishes the WB charge every hit. It can be assumed that Nicole met Misty during or even before the time when she became a newbie Hero since her first description already mentions Misty. 

After some time, Nicole realized she was still weaker than Misty and decided to learn more about necromancy, eventually summoning a better servant, Skull Eyes. Despite that, Misty was getting even stronger, and Nicole still considered herself too weak. This led her to call her sister, [[Persenachia]], to help her just as Misty acquired her VOID form. 

Nicole's plan backfired spectacularly, however, as Misty herself acknowledged Persenachia as a worthy rival. Even though Persenachia effectively stole Nicole's goal, she offered all her support to her little sister, helping her summon a new servant, Dead Phalanx. As Misty and Persenachia kept competing, Nicole began training swordsmanship with a weapon she forged herself, Soul Sword, and as soon as Misty made a contract with the lord of the underworld for more power, thus evolving once more into Raven, Malice resumed her career as Knight with an all-new fighting style, Dead Phalanx and a renewed confidence that, unbeknownst to her, finally earned Misty's respect.

Nicole's admiration for her older sister kept growing, what eventually led her into following Persenachia's steps and experimenting the ART-Type by making a contract with an ART servant, Yomi, also called Dead Slayer. Nicole apparently decided to use bladed weapons ever since she became Knight, as Yomi's "staff" is specifically a bladed staff, although most of the time she uses it to fire projectiles, sticking to her new ART-Type style.
