According to him, dolls are merely gears to keep the world turning smoothly. He finds the humanity in Remy and Lili a bit repulsive, but he is enamored with Guest's technical skill in creating such sophisticated "pseudo-humans." He is a deviant who believes Guest is the only technician on his level and considers them his person of destiny. He dotes on Acht as his best-made doll, but nothing more or less.

He looks up to Giel as his master, but even that is according to his design.
