In a world where sorcery is revered and mechanical technology is mocked, his personal interests were constantly rejected. As a defense mechanism, he came to believe that "everyone else is just too stupid to understand the greatness of machines."

He is personable toward everyone and handles conversations well on the surface. Internally, he looks down on those around him as being far "below" him, but he never lets this show.

Since the death of his lover, Guest, his intelligence has veered into madness. Unable to accept Guest's death, he is obsessed with "completely resurrecting Guest as a machine" by manufacturing a mechanical body and creating an AI and synthetic voice that mimic their living responses. However, things are not progressing as he hopes, and he continues to struggle through trial and error.
