Michael

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

Appearance
Possessing the body of Rudra, 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 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 – fitting considering the power he was born from. He was arrogant to an extent too. Feldway has remarked that Michael's presence reminds them of Veldanava.

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 there are innumerable ways to get there, he would be forgiven for enjoying the process.

Michael did not like imposing his mistakes onto others, and would rectify them to avoid causing friction in his future plans.

Background
Michael was initially a hollow skill that questioned its purpose 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 Lord of Justice and became a Manas, developing a firm will.

To enact their plan, Michael spent the next several centuries taking control of Rudra's body, whose soul wore out with each reincarnation ritual. Along the way, he dominated the minds of Rudra's closest subjects and his partner, Velgrynd. He also formed a truce with the Insectars and their king, Zelanus, whom Feldway and his 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.
