"You're nothing but a useless eater! Get out of this house!" Due to his brother's manipulation, Dio, who was falsely deemed to have no blessing, is expelled from his home by his father, who only cares about appearances. However, when his brother, fearing exposure, pushes him into the depths of a dungeon, Dio awakens the strongest blessing. Deciding to return home and see his brother's face, Dio finds his father trying to reverse the expulsion and kick out his brother instead. Despite his brother's desperate pleas, it's too late. "Pitiful, brother. And father, it's you who should leave." This is the story of a boy who lost everything and fell to the bottom, but rises to the top with the power of the strongest blessing.
