History
She and her husband wife lived in the house of their daughter and son-in-law, which permitted them to have an everyday role in their grandchildren's lives. Although Mako spent everyday with his family, she was disgusted by the abuse Kotaro subjected his son to for liking heroes.

One night, Tenko's Decay Quirk manifested and he ended up killing the family dog and his sister. Mako, her husband, and daughter appeared and are horrified with his acts. Begging for help, Tenko tries to reach his mother, but he touches the ground and his decay spreads, accidentally slaughtering them. All that remained of her was her hands, which were recovered by All For One and Tenko added them to his villain costume after he became Tomura Shigaraki.
