Michael

Michael (ミカエル) was the will of Ultimate Skill Michael that seeked to revive his original master and creator, Veldanava. He lost his life in battle against Rimuru Tempest.

Appearance
Possessing the body of Rudra Nam Ul Nasca, Michael had the same appearance, with his eyes depicted as red in illustrations. He originally wore Rudra's emperor clothing, but after the events of The Abyss Unleashed, he switched to a white outfit with red accents.

Personality
Michael was extremely self-righteous, believing that his way of thinking was supreme and embodied justice, befitting the virtue he represented. He was arrogant to an extent too. Feldway has remarked that Michael's presence reminds them of Veldanava. Michael did not like imposing his mistakes onto others, and would rectify them to avoid causing friction in his future plans.

Shortly before his death, Michael came to appreciate the value of emotions, which before then he had a hard time understanding as someone who relied on logical reasoning and calculations for his decisions. He came to believe that instead of getting worked up over every setback, it would be constructive to avoid making mistakes in the future. Even if there was only one perfect answer, since the ways to reach it are innumerable, he would be forgiven for taking time to enjoy the process.

After being consumed by Rimuru, he noted the sensation within the slime was a familiar comfort that he stopped feeling after losing Veldanava. He lived his final moments in happiness, his only regret leaving Feldway behind.

Background
Michael was originally a skill with a hollow ego that questioned its purpose for existing after the death of its creator, Veldanava. Seeking to revive him, it allied with Feldway who shared the same goal. Finding it inconvenient that it didn't have a proper name, Feldway named it "Michael", and as a result, Michael's core left the vessel of the skill and became a Manas, developing a firm will.

To enact their plan, Michael spent the next several centuries wresting control over Rudra's body, gradually succeeding the more latter's soul wore out with each reincarnation. He dominated the minds of Rudra's closest vassals, and his partner, Velgrynd. Michael, upon Feldway's recommendation, also formed a truce with the Insectars and their king, Zelanus, whom the Phantoms had long been in conflict with. Because of Rudra's incredible spiritual strength, Michael couldn't completely act freely and was forced to play along in his game with Demon Lord Guy Crimson to the very end.

At the climax of the war with Tempest, Rudra's soul was completely banished, erasing any fetters placed on Michael. Choosing to retreat, he left with Feldway, moving their base of operations to the Heavenly Star Palace.
