A member of a clan of exclusively female demons, they are not widely known but are infamous for their excessively potent motherly instincts. Mama with the help of her kin attacks the castle in hopes of securing a suitable male to impregnate her as per her clan's custom.
<hidden by spoiler settings> Fabio does not immediately recognise Mama for what she is until he is coerced into having sex with her. Fortunately for him his incubus nature prevents Mama from brainwashing him and he is in turn able to win her over to Primtine's cause.
Despite her appearance as a young girl, Mama and her kin embark on journeys looking for suitable males to bear their children. The children will always be female and are raised back in the Mama village to replenish the clan's numbers. After she is pregnant, the father is usually discarded. In the process of finding the appropriate seed, Mamas have developed a sinister reputation for smothering their potential targets with excessive motherly love which usually leaves their victims completely dependent on the Mama.
After recruitment, Mama tends to the psychological needs of homesick demons fighting for Farinase's cause. Fabio managed to extract a promise from her that she would not entrap males inside the castle for impregnation, so she uses her motherly nature to alleviate the soldier's emotional desires for comfort. Mama and her kin are also biologically programmed to mother others on a periodic basis or excessive stress builds up within them.
In her end, Mama returns to her village with Fabio's child as her quest is complete. Atypically, she hopes to return to Fabio's side together with their daughter after enough time has past.
