Arlette Escardos is a member of the Escardos magus family. She is the wife of Mr. Escardos and the mother of Flat Escardos and a daughter. Arlette is absolutely terrified of her own son Flat, at first thinking he was just deficient but eventually reaching the conclusion that he was a monstrous phenomenon that they somehow mistook for their child. She comes to believe that putting an end to him was the true culmination of the Escardos family magecraft. (Source: TYPE-MOON Wiki)
