full headcanon:

Since Seto and Mokuba’s parents never appeared in the series, I’ve taken it upon myaelf to create them.
Their mother gave Kaiba his blue eyes and Mokuba his black hair. She was Gozaburou’s fiancée in high school where she met the boys’ father, who have Kaiba his brown hair and Mokuba his steel eyes. Their relatives disliked the fact a high class girl who was already engaged wanted a commoner boy. Due to this disliking, when the brothers’ parents died, the relatives got pay back on the brothers by stealing their inheritance. Gozaburou also got in on the revenge by adopting his ex-fiancée’s children and abusing them.
If Seto and Mokuba’s story wasn’t already sad, I think I’ve made it even more sad.
