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. His eyes are depicted 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 – which is fitting considering the power he was born from. His personality gradually bled into Rudra's over the years of his soul deteriorating, causing the loss of the emperor's ideals. 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 experience and appreciate the value of emotions for the first time, 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 everytime he encountered setbacks, it would be constructive to avoid making mistakes in the future. Even if there was only one perfect answer, as there infinite ways to get there, he would be forgiven for enjoying the process. After all, the shortest way was not always the correct one.

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 being that questioned his purpose after the death of his creator, Veldanava. Seeking to revive him, he allied with Feldway who shared the same goal. Finding it inconvenient that he didn't have a proper name, Feldway named him "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, chipping away at his soul with each reincarnation. Along the way, he dominated the minds of his closest subjects and Velgrynd. He also formed a truce with the Insectars and their king, Zelanus, whom Feldway and his Phantoms had long been in conflict with.
