Gwen Hasler is a human character.
Gwen is a goth girl whose interests lie in art and astronomy. She is smart, independent, and level-headed, stating her best quality is her inability to get excited over minuscule things. Her attitude at first seems cold and harsh, but she is not a bitter person, rather cautious of whom she lets into her life.
