Diablo's Mysterious Origins
From the pursuit of power to personal entertainment
The true origin of Diablo dates back to the beginning of the world. As Primordials, Noir, now known as Diablo, and the rest of his counterparts were created by the Creator God, Veldanava, a creation of the Seven Angels of Origin. In order to balance these creatures created from the great Holy Spirit of light, the seven Primordial creatures created from the Great Holy Spirit of darkness were created. These creatures were so powerful that they ruled the demon realm.
While the two Primordials submitted to Rouge, the most powerful of the seven, Diablo, on the other hand, never submitted to Rouge, and when they fought it resulted in a draw that showed just how powerful Diablo was. Unlike the other Primordials, Diablo did not pursue power as he quickly became bored and instead lived as he pleased, immersing himself in human societies using various tricks and machinations for his personal amusement.
After his creation and battle with Rouge, little is known about how Diablo lived his early life. However, it is revealed to fans and characters alike that the knowledge possessed by this ancient demon is enough to bring down the kingdom.
The Devil's Rise to Power
From Noir to Diablo
Diablo's rise to power doesn't involve harrowing stories or grand adventures because he was born powerful. While he had long since stopped striving for power, when he fought Rouge, the first Primordial, he managed to bind, earning the ancient demon's respect. Before Rimuru gave him the name Diablo, Noir was one of the most feared creatures in the world. This leaves fans wondering just how much more powerful he's gotten since being named, from an actual demon, no less.
In terms of abilities, Diablo is the strongest of all of Rimuru's subordinates, so gaining more and more power isn't enough to truly show his rise in power. Diablo's true rise to power is not about power, but about the influence he was able to gain while working as Rimuru's subject. Normally, Primordials don't get too involved in world affairs and just do certain things to cure boredom. This is especially evident in how characters like Guy Crimson care so much about maintaining the world's balance of power. However, after being named and thrust into the limelight, Diablo's influence began to spread rapidly as a powerful entity of the ruler of the Jura Tempest Federation.
The depth of Diablo's loyalty
Diablo serves as more than a subordinate
From the moment he was summoned and named Rimuru Tempest, Diablo's unwavering loyalty to his master knows no bounds, making for an interesting aspect of the series. After all, why would an all-powerful Primeval simply and forcefully force itself to become another's subordinate?
Rimuru never really intended to summon Diablo or Primordial. Interestingly, Diablo was the one who strongly answered Rimuru's call for a greater demon. Before being summoned, Diablo gained interest in the upcoming slime through Shizu Sensei. In the past, she caught Diablo's attention by repelling him with her anti-magic mask. Later, the same mesmerizing mask shattered when it came into contact with Rimuru's power. Seeing the interesting events unfold before his eyes, Diablo came to the conclusion that Rimuru was the ticket to the “truth of the world” and had since silently pledged his allegiance, even before he was summoned.
When it came to fulfilling Rimuru's demands, Diablo would do anything and everything possible to ensure that his master's wishes were met. His devotion was absolute and not born of gratitude or respect for his power like his other subordinates. His loyalty was born out of instant respect and belief in Rimura's potential and character. Diablo had no need to serve anyone, but he trusted Rimuru more than he deserved his loyalty. in a way this makes Diablo perhaps Rimuru's most loyal servant.
Strategic maneuvers
How Diablo's cunning secures Jura Tempest's future
To show Diablo's inexplicable devotion, the ancient Primordial not only obeys his master, but also constantly acts according to strategic plans to achieve his master's goals. With the kingdom of Falmuth subject to Rimuru, Diablo proved to be a necessary asset. His wit, tactics, and overall method of subduing the land of Falmuth was extraordinary. He did not simply destroy them as many would have expected, but used his overwhelming power in a strategic political way.
Conquering the Kingdom of Falmuth behind the scenes is certainly impressive, but getting other Primordials, beings of the same level as him, to serve Rimuru is simply unimaginable. To show his intense devotion, Diablo recruited hundreds of demons to his master's cause and created the Black Numbers, the Jura Tempest Federation's trump card army. Consisting of four Primordials, the strength of this army can be called the strongest in the world. Why Diablo would go to such great lengths for his master is beyond comprehension, but by enlisting three other Primordials to serve his master's cause, his unwavering loyalty is more than commendable.
Diablo's tactical brilliance is one of the main reasons why Rimuru has achieved so much, so quickly. Slime is very brilliant with leadership talent, but when it comes to tactical brilliance, he loses to the Primal Demon who lives for thousands of years. Serving as a demon with more than just strength, Diablo's intellect proved essential to expanding the influence of the Jura Tempest Federation and cementing Rimuru's place as one of the most powerful beings in the world. His ability to foresee future events and take care of trouble before it arises is uncanny.
Additionally, instead of constantly threatening individuals into obedience, a tactic he used with the Kingdom of Falmuth, Diablo knows when to use diplomacy, as seen in his meeting with the reporters present at the subjugation of the Kingdom of Falmuth. Simply coercing the reporters might have worked, but saving their lives, allowing them to witness the true evil of the Falmuth Kingdom, and then declaring himself a loyal follower of Rimuru Tempest, a monster that wants to bond with humans, worked much more. . In this way, Diablo portrayed himself as a “beautiful” demon who only wanted to pursue peace with humans, which in turn speaks volumes for his fiefdom.
The Strength Of Trust: Rimuru and Diablo's Bond
How Diablo's loyalty shapes his actions
Diablo's effect on Rimuru and the Jura Tempest Federation in general is positive. With his extraordinary abilities and tactical astuteness, the Primal Demon is capable of many things. With him at Rimuru's side, Rimuru is expected to have the upper hand in various situations, and as Rimuru grows in strength, Diablo is expected to be right next to him. Diablo betraying Rimuru is an act few can imagine; however, with the 70th episode That time I was reincarnated as slime series, Queen of the Elves, Elmesia El-Ruivell seems to believe it is possible.
Fortunately, Rimuru had personally stated that if the primordial demon ever got out of control, he would be there to stop it and personally take responsibility. Given his master's immense trust in him, Diablo was satisfied with such an answer. The relationship between master and servant seemed to be instant, but this bond was cemented by the immense trust between the two parties. With logic and loyalty at his command, Diablo is expected to do what is best for his master.
That time I was reincarnated as slime is available to stream on Crunchyroll.
