Diablo

ディアブロ

Diablo, also known as Noir is one of the seven Demon Primordials and an Executive of the Jura Tempest Federation as the second Secretary of Rimuru Tempest. Black hair with streaks of red and gold, as well as golden eyes, Noir was finely dressed in garments like that of a prince. Other than that he looked like a normal human, though he was able to unfold wings as well. Diablo's change in appearance is possibly the least drastic after any evolution, only his princely garments were replaced by a Butler outfit, reflecting his wish to serve Rimuru, but despite that, his dignity didn't decrease, but rather even increased. Diablo is whimsical but also very calculative when he wants to be. He usually shows an absolutely composed attitude, but whenever anyone insults Rimuru, his polite exterior turns into a cold form of malice and he proceeds to punish the "sinner" in the most painful way imaginable unless it goes against Rimuru's orders. However, when someone has a good relationship with Rimuru, Diablo usually treats them amiable, though he might still manipulate them for his own ends, with "his own ends" usually referring to being close to Rimuru more often. Diablo follows Rimuru's orders to the letter. When tasked with increasing the difficulty of Flamaire's test as a guard for guests to Tempest, Diablo summoned a moderately strong monster. The moment Flamaire got paralyzed by the creature's goo and still showed a will to fight, Diablo sent the creature away and went to report back on Flamaire's actions. Should there be some "grey area" in his instructions, Diablo has the freedom to carry out his orders how he sees fit. The greatest show of Diablo's loyalty to Rimuru was recruiting hundreds of other demons (including the last three progenitors) to serve his master; the creation of the Black Numbers, who became the de facto strongest fighting force in Tempest.
