I like his sister. She is a great big sister, although I am sensing a bit of incest. The fact that this anime is actually an isekai just made it worse. I get the feeling that it's just going to be as painfully mid as other Isekais

His being a 30-year-old virgin in the body of a 9-year-old is just another trope. What's the point of using this cliché without adding anything new?
