Ila is a member of the magician's guild as well as Louie's closest friend, and it is suggested that she may carry deeper feelings than just that of friendship. She collects many magical items which either help Louie or cause him trouble. Often she lends the group a helping hand and is a major supporting character in the anime. She is also the daughter of a very wealthy merchant, who deals in many rare and exotic goods, which comes in handy more than once in the anime.
