His Soul is Marching On to Another World; or, the John Brown Isekai (Fall of the Slave Harem)

And heaven shall ring with anthems o’er the deed they mean to do,
For his soul is marching on.

The land of Gemeinplatz is a land filled with fantastical creatures, adventurers looking to slay them, and heroes looking to distinguish themselves from the adventurers. The most common of these heroes are those who come from Earth, who enjoy a most leisurely time with their cheat skills. It’s a perfect world, the utopia of those who wish to become overpowered and get their own power fantasy, where even the most everyman of the everyman can pull themselves by their bootstraps and become a hero.

Yet, underneath this “Gemeinplatzer Dream” is a disgusting truth.

To satisfy the needs of heroes who can’t find function like a normal human being (which most of them can’t), the lucrative Gemeinplatz slave trade crushes the dreams and ruins the lives of hundreds every day. These slaves endlessly labor, in the harems of so-called heroes, at the mansions of the landowning “heroes”, and as rare materials for various dubious magical spells.

In a world that looks down at them as demi-human, where the ruling class has no incentive to end this profitable trade, in which their oppressors are overpowered as all hell, what hope is there for the slaves?

What hope is there, is named John Brown. This time, he’ll finish what he started.
