Good and Evil are recurring ideas in the story. Part of Eiji's journey is characterized by how he deals with people. Although he finds himself in dangerous situations, Good and Evil are not clearly marked territories. When he is young, Eiji can afford to label people, as he does his mother, but as he matures he is forced to consider the complexities that give rise to a given individual's actions. Daimon, whom we might consider a bad guy due to his treatment of Miriam and his betrayal of Eiji's trust, turns out to be a nice enough fellow who puts Eiji in touch with Ms. Yamaya.
