The Mother is the Servamp of Wrath and the fourth oldest of the eight Servamps. The Mother is currently under a temporary contract with Izuna Nobel as her Eve. She is also the only female Servamp. Being the Servamp of Wrath, she takes that trait herself, always looking grouchy or frowning, giving an impression that she's angry; Mahiru assumes she is angry when they first meet, but she claims that she is only acting cool. Despite her alias, she is kind to other Servamps and her Subclasses. Although, this does not stop Lily from being afraid of her. It is said that she will not get very angry without a valid reason.
