Grandmother Norstein is a minor character in Digimon Savers.
She is Thoma and Relena's paternal grandmother, Franz's Mother. Being part of the Norstein Family, she is very aristocratic.
She appears in several flashbacks in DS42. She disapproved of Thoma inheriting the Norstein name and would not acknowledge him as a legitimate child of the bloodline due to his Japanese heritage from his late mother. She classed Thoma as still being a Norstein but yet paradoxically not a Norstein because of his inherited genetic phenotypes - blue eyes and blonde hair.
When Relena was born, both she and her mother were in danger due to postnatal complications as a result of labor, so she ordered the doctors to do whatever they can to save Relena's life. She brands Relena as a "true" Norstein and the rightful heir to the Norstein lineage, but because of her weak condition, possibly due to a congenital disease of such, she has no choice but to decide that Thoma is to be inheritor of the Norstein lineage. She also orders Franz to find a proper wife for him in an arranged marriage.
