Ultima

Ultima, also known as Violet, is one of the Primordials that joined Tempest after Diablo recruited her. She serves as the Chief Prosecutor in the legal department of Tempest's government as well as a leader of the Black Numbers along with Testarossa and Carrera and is counted as a member among Rimuru's Twelve Guardian Lords. Ultima takes the appearance of a cute and beautiful girl. She has middle length purple hair tied into a side ponytail, as well as purple fingernails. When she's off the clock she wears a variety of purple-colored dresses as casual wear and when she's serious she wears a black skirted military uniform with an armband on her left arm. As a Daemon, she has the characteristic horns and wings of their race, something she usually keeps hidden. She has six bat-like wings on her back that she can freely shapeshift into whatever she desires. Ultima, on the outside, appears to be a simple-minded and carefree princess-like person; but on the inside, she's an extremely calculative and scheming person who's always planning her next move. Befitting a Daemon, she's extremely cruel towards her enemies, preferring to capture their souls and torture them rather than outright kill them, which she gets a sadistic pleasure from doing. Despite this, she doesn't approve of her mischief being messed up and will cut ties with or sometimes kill her subordinates if they decide to take matters in their own hands against her orders. She does not care about her admirers, as she killed Gustav without hesitation after he did not complete his goal correctly. Though Ultima takes joy in the suffering of others, she feels an even greater pleasure when those she tortures or observes struggling, overcome their adversity. She's fond of such individuals, and is even willing to reward or lend a hand to them out of gratitude for entertaining her. One notable instance of this is when she revived Towa as a sort of apology for the actions of her subordinate, who violated the terms of their contract and ruined her game.
