To him, this is way more important than tasks like toppling nations and political machinations. Diablo's happiest thing to do is butler/housekeeping work for Rimuru.It's said by Beretta and Guy Crimson that black colored daemons are the smallest in number as Diablo doesn't like to create 'descendants.'.Diablo's naming took half of Rimuru's total magicules reserves even though his total magicule capacity increased by ten times after becoming a demon lord.Rimuru named Diablo after the Supercar Lamborghini Diablo.After some further events, Noir finally received the name 'Diablo' from Rimuru and evolved into a Daemon Lord. He failed because Beretta, his own descendant, answered the summon first much to his chagrin.įinally, when Rimuru did another Greater Daemon Summoning to catch the hiding Razen, Noir managed to answer the call alongside two of his Greater Daemon followers. He tried to get summoned when Rimuru performed a Greater Daemon Summoning within The Dungeon.

When he saw that the mask broke and lost its power when the mask came into Rimuru's hands, Noir came to the conclusion that Rimuru is connected to that power of the mask that surpasses time itself as he witnessed and that Rimuru is, therefore, the key to the 'truth of the world.' After those events, he returned to the Spiritual World and continued observing Shizue and the mask in secret. During a confrontation, where Noir was about to finish her off, he was repelled by Shizue's Anti-Magic Mask instead, making Noir realize that the mask had an incomprehensible nature. One day when he personally answered a Demon Summon of the Silver Wings on a whim, he had a chance encounter with Shizue Izawa.

Due to that he one day stopped pursuing power as his power efficiency became so high that any fights were too easy for him, causing him to remain as an Arch Daemon despite having enough power to evolve into a Daemon Lord already. Thought of as strange by the other Primordials, Noir only acted on whims and didn't show any regular behavior, to the irritation of some of the other Primordials. Shizu's replacement, Tiss did a desperate summon to save Shizu's Students from a Phantom, only for the unnamed Diablo to practically give his aid for 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. 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.ĭiablo also despises owing a debt, even to someone who has already passed on. Should there be some 'grey area' in his instructions, Diablo has the freedom to carry out his orders how he sees fit. The moment Framea 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 Framea's actions. When tasked with increasing the difficulty of Framea's test as a guard for guests to Tempest, Diablo summoned a moderately strong monster. However, when someone has a good relationship with Rimuru, Diablo usually treats them in an amiable way, though he might still manipulate them for his own ends, with 'his own ends' usually referring to being close to Rimuru more often.ĭiablo follows Rimuru's orders to the letter. 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. Other than that he looked like a normal human, though he was able to unfold wings as well.ĭiablo'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.ĭiablo is whimsical but also very calculative when he wants to be. Black hair with streaks of red and gold, as well as golden eyes, Noir was finely dressed in garments like that of a prince.
