Saeko was once a powerful angel before being cast down back to earth because she had zero respect for the rules implaced by her superiors. She is very social, and is pretty popular with local clubgoers, yet she doesn't care for close relationships with others and actually has very few true friends. Saeko's primary belief is that the rules apply to everyone but her, and seems to not care about how her actions or words could affect those around her. As far as romantic relationships, Saeko loathes the idea of commitment, and tends to have more flings than a steady relationship. She tries to weasel her way out of relationships before she finds herself catching hard feelings for the other person due to her commitment issues.
