Gods I fucking wished any of them actually did liberation. They just buy slaves and then feel bad about it (but it’s okay, the slave really likes them as a master 🤮)

Give me “I Got Reincarnated into a World of Slavery. So I Killed All the Slavers”

The closest I’ve seen to that is “The World’s Finest Assassin Gets Reincarnated in Another World as an Aristocrat”, but uh, it’s really far off from that concept. They do kill a bunch of billionaires buying slaves in the in medias res of the first episode, though. Which is nice
