Mihai Florescu is portrayed as a cynical and self-centered individual who often treats those around him as playthings for his own amusement. He is prone to manipulation and deceit, sometimes placing others in dangerous situations purely for entertainment. His lack of empathy and understanding of how his actions affect others makes him unpredictable, and even Inugami has acknowledged Mihai as potentially dangerous when in a foul mood. Despite this, Mihai is not inherently malicious he is willing to offer help when a situation captures his interest.

Though he projects a casual and indifferent attitude, Mihai displays unexpected dedication and diligence when he commits to a task.

He often refers to himself with various impressive titles, though it remains unclear whether these are genuine or exaggerated.

Despite his ego, he is sensitive to disapproval and prefers to avoid being scolded.
