Carrera

Carrera (カレラ), also known as Jaune (原初の黄), is one of the Primordials who joined Tempest after Diablo recruited her. She serves as the Chief Justice Officer of the Supreme Court in Tempest and a leader of the Black Numbers while also holding a spot among the Twelve Guardian Lords.

Appearance
Carrera assumes the appearance of a young woman with shoulder-length blonde hair and blue eyes. She wears a black snow coat with a skull pin over a white shirt and tie. Her appearance gives off the vibe of a high school delinquent. She is slightly taller than Ultima but shorter than Testarossa.

Personality
Just as her appearance suggests, Carrera has the personality of a high school delinquent. She is a carefree, energetic battle maniac who loves firing off nuclear magic for fun. Other than that, she is egocentric and gets mad easily. Though arrogant, Carrera does acknowledge her opponents when they prove to be a challenge for her as was the case with Tatsuya Kondou.

While fighting Kondou, she admitted to underestimating humans too much and was quick to revise this attitude and face him seriously. She gained a noticeable amount of respect for him when he managed to stand his ground and even rival her power. She accepted Kondou's powers and soul in exchange for his wish to kill the emperor despite her lineage being known for being unnegotiable in deals.

Background
Carrera, like her other primordial brethren, was born during the dawn of time before the creation of heaven and earth as the demonic counterparts to the Seven Angels of Origin. Her and the other primordials ruled Hell undisturbed for an eternity with Rouge as its overlord. When Bleu and Vert were resurrected completely loyal to Rouge after their attempt to overthrow him, Carrera, Blanc, and Violet agreed to never fight each other directly, instead preferring to outsmart each other in things like games and who could incarnate in the material world first.

Hundreds of years ago, before Diablo recruited her, she created a powerful life-form in a small country in Sorcerer's Dynasty Sarion but it was taken down by Leon Cromwell in his days as hero. She was frustrated, unaware that it was Violet who led Leon there. As a result of this, she spent all of her time developing flashy and powerful magic as vengeance for Leon's interference. Leon's knights tried negotiating with her multiple times but they were ignored each time. Worse still, she caused them a great deal of trouble by firing nuclear magic upon their city on a near daily basis as a provocation to Leon so he would challenge her to a fight since Guy acknowledged his strength.

Trivia
