It's the year 1859, and John Brown finds himself with a noose around his neck. As his neck snaps, the abolitionist finds himself face to face with God. God's side project, where she sends other people to a new world to battle demon kings and solve its problems has backfired. They've been getting power hungry and have started doing weird stuff like owning slave harems. Thus, God gives John Brown a mission- Kill all of the other reincarnators and free the slaves.

However, due to a request for his old Sharps Rifle as his special ability and his lack of knowledge about the genre, he starts with a few problems. God has disconnected him from the litRPG system of the world and gave him a preset build instead. And most importantly, he is now a she! With the power of god and guns on their side, JB is determined to kill the reincarnators and slavers that plague this land no matter what!
