Mikhail is the first member of the Investiture Beings to appear in Blue Dragon: Trials of the Seven Shadows. His background as an Investiture Being places him among a group of powerful entities central to the second season’s conflict. He is characterized by a strong sense of arrogance, which proves to be his greatest weakness and a defining feature of his personality. This arrogance influences his motivations, as he approaches confrontations with a belief in his own superiority, often underestimating his opponents.

In the story, Mikhail serves as an early antagonist whom Shu and his friends locate through information obtained from Rottarace. Shu and Marumaro engage him in battle to resolve the threat he poses. His role is that of a formidable obstacle the heroes must overcome early in their journey. Beyond this encounter, the narrative does not explore significant development or deeper motivations for Mikhail; his appearance is primarily tied to the trial he represents. His notable abilities are implied to be considerable, consistent with his status as an Investiture Being, but specific techniques or powers are not elaborated upon in the available material. Key relationships are limited to his direct conflict with Shu and Marumaro, and he does not form lasting bonds with the main cast.
