Rose occasionally tries to feed him bad ideas, but since he knows they are bad, he ignores them and doesn't let them sink in. He feels sympathy for Xeno every day—well, sympathy of a sort.

A crybaby who cries often but doesn't sulk (because he believes Guest will definitely comfort him). He hates dirty jokes and becomes a crying drunk when intoxicated.

He often runs to Guest crying, usually because Rose was mean to him. Even though he's bad at acting spoiled, his sense of personal space is non-existent.
