The Devil Eater's Beast Tamer - Expelled from my family for being 'a useless person without divine protection', but I awakened with the strongest power, so now I'm unstoppable

Dee, deemed to be without divine protection by his brother who bribed a priest, is expelled from his home by his father, who only cares about appearances. However, at the bottom of the dungeon where his brother pushed him, fearing his schemes would be exposed, Dee awakens the strongest divine protection. He returns home to confront his brother, only to find his father trying to take back his expulsion order. His brother begs for forgiveness, but it's too late. Dee overpowers them both and expels them instead. This is the story of a boy who, having lost everything and fallen into the abyss, rises to the top with his overwhelming power.
