At school, before entering the Dark World, Susie appears as a bully. She acts very rude toward other students, insulting them and even threatening them with physical violence. She does not have any friends and appears to be convinced that everyone hates her. Susie may, however, use this as an excuse to act rudely. When she enters the Dark World, Susie beats up every enemy she meets and is uninterested in being a Hero of Light, even saying to Ralsei that the end of the world is "none of [her] business" and that it "might be kind of fun."
