Anne-Marte Du Bou Sanson

Anne-Marte Dubut Sanson (アンヌ＝マルト・デュビュ・サンソン Annu Maruto Dubyu Sanson) is mather of Jean Baptiste and Nicolas-Charles, as well as grandmother to the protagonist of story Charles-Henri Sanson.

She is portrayed as cold-hearted woman of the Sanson-clan.

After having her face scarred by Marie-Joseph, she lost her dignity and needed to marry an artisan and as such leave the Sanson family.

Appearance
Anne-Marte is an elderly woman with light hair and light eyes, having her hair styled in an elegant updo. When she was younger, she was shown to have been a quite beautiful woman, even now as an elderly woman she appears to have aged very gracefully.

Personality
She is quite cold-heated, cruel and sadistic woman as she enjoys in watching executions as well as not having much compassion for her own children and seeing them only as tools to be used and discarded when they are no longer of use.

As it was shown by her using her motherly love to manipulate Nicolas into helping Charles with execution, as well as turning against her oldest son Baptiste by having his order regarding Jack dismissed as she reminds her son that now new "Monsieur de Paris" is Charles and as such Charles is nthen ew head of Sanson family and his orders are the only ones to be obeyed now and not Baptiste's.

This shows that she at least has affection for her grandson Charles. However, this affection can be in reality manipulation, for as far as we know.

It's hard to tell if her personality is caused by psychopathy (in the clinical sense) or fanatism. She always talks about making a great executioner to her sons or grandsons. It can be because she is really into the code of honor of dynastic executioners or she is motivated to preserve her own comfort and well-being by having men chopping heads, and thus depend on them.
