Carrera

"Was that too scary? My apologies, I needed to cool off a little. I was making light of you, or rather, humans in general, and ended up holding back you see. Who knew. Who could possibly know that I…… Would actually, truly, seriously face off against a human."

- Carrera

"Menace Lord" Carrera [ カレラ,  Karera] was one of the Demons summoned by Diablo to serve Rimuru. She was Arch Demon when summoned, but evolved to Demon Duke after she was named by Rimuru.

Dispatched to a corps as an intelligence officer

Personality
She had a childish personality which didn't use her brain and very scary once she gets mad.

While fighting Kondo, 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 powers. After their fight was interrupted and Kondo was assassinated, she was furious at their attacker and noticeably depressed. She accepted Kondo's powers and soul in exchange for his whim to kill the emperor(free him from his burdens) and later avenged his death, going out of her own way to do so.

Abilities
Gravity collapse: produces a huge gravitational force on the targeted area. It can cause an implosion if too strong. Rimuru believe that it may be possible for her to create a small black hole or something similar that would result in a very large scale uncontrolled destruction.
