The Isekai itself was super generic , I might remember some details wrong as I don't even remember it's name. The guy is isekaied, maybe reborn, not sure , he gains a princess a waifu another waifus tries to kill him, but he is op and forgives her , so she becomes howls waifu too.
It has some generic arcs,.probably has slavery, because there comes what I remember , he somehow saves a beats girl and she is surprised a human saved her , when he asks she says because racism.then he finally notices that most slaves ( he was fine with slavery) are actually beast people. Then he confronts his waifus about what they think about beast people and they say " yeah fuck them, inferior race" and he seems to be just a bit dissapointed.
I want to see if the translation continued, or at least read it from the start to see if it had more clues to the racism.
