Asa is a quiet and unsociable girl. She dislikes her classmates, frequently wishing they would drop dead and spurning any offers of friendship. She has a very negative outlook on the world, other humans, and Devils, and tends to assume the worst of others. She is, however, very fond of one person: her partner, whom she is eternally grateful for for being "different than the rest". Though her looks aren't as noticeable compared to others, she is conventionally attractive.
