A guy dies and faces a god who offers him vague promises of a better life as long as he carries out the God's plan. However, when that plan involves tracking down, enslaving, and impregnating his five sisters, what's he going to do? With a careful wit, a yandere mother, and no clue… an MC in the body of a hated devil must conquer his sisters and the human realm by force!

With an intelligent main character that thinks in creative ways, and plenty of heart wrenching archetypes to argue over who "best girl" is, this is a thought out and enjoyable read.
