His Soul Is Marching On to Another World; or, the John Brown Isekai
B60/100Web serial by The Cabbage Preacher
The land of Gemeinplatz is filled with fantastical creatures, adventurers, and heroes — most of them transported from Earth and blessed with cheat skills. On the surface, it's a perfect power-fantasy world where even the most ordinary person can pull themselves up by their bootstraps. Yet beneath this "Gemeinplatzer Dream" is a disgusting truth. To satisfy the needs of heroes who can't function like normal humans, a lucrative slave trade crushes the dreams and ruins the lives of hundreds every day. Demi-humans labor in harems and mansions, treated as less than people by a ruling class with every incentive to keep the system going. In a world where the oppressors are overpowered and the odds are impossible, the hope for the enslaved has a name: John Brown. This time, he'll finish what he started.
