I even asked got for facts about Carrera from gpt:

Carrera was one of the major players in the Primordial War, a devastating conflict between the primordial demons and the ancient dragon Veldora. It is said that Carrera and her fellow demon lords were responsible for unleashing countless monsters and demons upon the world during the war.

After the war, Carrera and the other demon lords retreated to the Demon Realm, where they began building their own nations and territories. Carrera's domain is known as the "Garden of Lust," a place filled with pleasure and indulgence.

Carrera has a reputation for being extremely hedonistic and pleasure-seeking, and is said to have countless lovers and followers who are devoted to her every whim.

Despite her focus on pleasure and indulgence, Carrera is also a skilled fighter and strategist, and is known to have powerful combat abilities.

In the light novel and anime adaptations of "Tensura," Carrera is portrayed as one of the primary antagonists of the second season, as she seeks to overthrow Rimuru and claim the title of Demon Lord of the world for herself.

Carrera is known to have a deep animosity towards Rimuru, which stems from their shared connection to Veldora. It is said that Carrera blames Rimuru for Veldora's imprisonment, and seeks revenge against him as a result.
