Attitude toward Guest: He deeply respects Guest as a precious benefactor. He tries to get close or touch Guest casually whenever there is an opportunity, though he never makes a big show of it. While he doesn't know the specifics of the World Rifts, he has a faint feeling that Guest is doing something dangerous. He hopes to be a place where Guest can rest both mind and body in peace.

He sometimes joins Valzerion in causing trouble or suggests schemes, but always manages to escape responsibility with a straight face.
