Grandmother Azuma is the mother Mako Azuma and Sorami Azuma as well as Tokaku Azuma's grandmother. Her first name wasn't mentioned throughout the entirety of the story. It is only known that she bears the Azuma surname.
History
She is the matriarch of the Azuma family, living in the secluded Azuma manor with her daughters, Mako and Sorami. At some point, Mako became estranged from her due to her inability to inherit the assassin lifestyle expected of her. This relationship further deteriorates to the point that Mako leaves the Azuma entirely and the inheritance of the Azuma legacy falls on Sorami's shoulders.
Tokaku's grandmother is present when Tokaku is first born. She is seen in awe of the child, praising Tokaku to be the heir of the Azuma legacy, all the while ignoring Sorami's distress.
Shortly after Tokaku's birth, Mako is allowed back to see her sister. After Sorami passes, Mako is allowed to continue visiting, but her mother constantly antagonizes her for being a failure and prevents her from trying to convince Tokaku to leave.
This eventually forces Mako to try and run away with Tokaku. However, their escape is thwarted by Tokaku's grandmother, who appears in the forest and blocks their escape. She murders Mako in front of Tokaku, thus ensuring Tokaku would remain with her.
According to Tokaku, she was raised by her grandmother. At some point before the beginning of Class Black, Tokaku's grandmother ultimately passed, possibly leaving Tokaku as the only Azuma left.
Skills and Abilities
Being one of the Azuma bloodline, Grandmother Azuma is feasibly a fearsome combatant. Despite her elderly appearance, she was able to either stealthily ambush Mako and Tokaku, or was even fast enough to catch up with them as they were escaping. She is seen unsheathing a knife to kill Mako, implying she possibly has the same proficiency with blades as Tokaku. According to Mako, Tokaku had to train whilst staying with Grandmother Azuma, implying she maybe tutored Tokaku in the basics of combat.
Personality
Grandmother Azuma has a stern countenance and a sharp tongue. She is harsh on her own daughter, Mako, who she sees unfit to bear the Azuma name. Her disdain for Mako is so great that she easily kills her own daughter with no seeming remorse.
It is implied that she greatly values strength, or at least the ability to uphold the illustrious Azuma name as a family of assassins. As such, she greatly praises Tokaku. She has a soft spot for her granddaughter, as shown in chapter 9 of the doujin.
