This is a very odd Isekai featuring a regular dude who obtained some skills which includes one relating to mind reading and eaves dropping? He discovers the princess who was supposed to be his "supporter" is an extreme rascist who hates ANYTHING that isn't natively human of their world. The MC even confirms it himself they are going so far to seal his skills and dispose of him when he ain't useful anymore? In the first chapter bruh, that's quite wild. So the story ends up becoming "how to escape the magic world and not get killed." He is clearly not on board with saving the worldfrom the demons or so. He is just going along with training and is using his abilities to secretly manipulate the princess with pleasure.

This is a 2.5 star / 5 star manga, it's narrow minded with a cheap MC.
