Diablo Husbando

Diablo, also known as Noir is one of the seven Primordial Daemons and an Executive of the Jura Tempest Federation, serving as a secretary and Butler to Rimuru Tempest. He is the leader of the Black Numbers and is Rimuru's most powerful subordinate among the Twelve Guardian Lords and the Three Top. Black hair with streaks of red and gold, as well as golden eyes with red pupils and black sclerae, 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, with only his princely garments being replaced by a Butler outfit, reflecting his wish to serve Rimuru. Despite that, however, his dignity did not decrease, but rather increased instead. Diablo is whimsical but also very calculative when he wants to be. He usually displays an absolutely composed attitude, but whenever anyone insults Rimuru, his polite exterior turns into one of cold malice as he proceeds to punish the "sinner" in the most excruciating way imaginable, unless it goes against Rimuru's orders. However, when one has a good relationship with Rimuru, Diablo usually treats them in an amiable way, though that does not mean he won't manipulate them for his own ends, "his own ends" usually referring to being close to Rimuru more often. Diablo follows Rimuru's orders down to the letter. When tasked with increasing the difficulty of Framea's test as a guard for guests to Tempest, Diablo had summoned a moderately strong monster. Upon seeing Framea's will to fight despite being paralyzed by the creature's goo, Diablo sent the creature away and returned to report back on her actions. Should there be any "grey areas" 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 daemons, including the last three Primordials, to serve his master; the creation of the Black Numbers, who became the de facto strongest fighting force in Tempest. Diablo also despises owing a debt, even to someone who has already passed on. Shizu's replacement, Tiss attempted a desperate summon to save Shizu's Students from a Phantom, only for the unnamed Diablo to offer his aid for what was practically a pittance of a price by forbidding her from mentioning his involvement, and proceeded to slaughter the aggressor in a truly horrific fashion, thus fulfilling his debt.
