Carrera/Chronology

Hero Awakening arc
She was recruited by Diablo who was looking for subordinates to help out with chores. At first, Rimuru thought she wasn't strong but Raphael quickly corrected him. When she was introducing herself, she let out a bit of her aura to try and intimidate Rimuru but he didn't notice it. Diablo wanted to scold her for that but Rimuru stopped him.

After changing locations, the unnamed Carrera gained a physical body by fusing together with an Emulated Soul and inhabiting one of the many homunculi bodies in the growth capsules prepared by Rimuru. Fitting for their status, all 3 Primordials' skeleton has gold mixed in and turned into Orichalcum, further improving the performance. After she gained her body, Rimuru named her. From this, she evolved from Arch Daemon to Daemon Lord. In addition, she brought along 2 servants and 200 soldiers. The 2 servants were named Agera and Esprit and both have their cap as Arch Daemons removed.

Later she was assigned to be Chief Justice Officer of the Supreme Court in Tempest. She happily accepted it and said she would judge people with the utmost fairness.
