Didit is a noble living in the Goa Kingdom on Dawn Island. She is the wife of Outlook III, the biological mother of Sabo, and the adoptive mother of Sterry
She has a stereotypical personality of a Noble, and only seeks to further their noble status. This was clearly seen when her son got into a fight with a noble boy of a higher status who used a weapon on him, she apologized to the family while comforting the boy, completely ignoring her own son's injuries.
