Eh, the protagonist is pretty apathetic for the most part, though he has a small concern for small girls, and has made a fetish of it. I wouldn't take this manga too seriously so far, as its downplaying nature is part of its satirical attempt at isekai tropes. Bit of a stretch to say, but it seems the next wave of isekai is going to be the reaction wave that up and mocks the previous wave through some level of self-awareness. But yeah. There's nothing necessarily profound about this manga, and I wouldn't say all the jokes are in great taste, dark humor or not, but it's still something I'll read just because it's interesting enough. That, and I'm kinda hardened to dark themes, so I like to try picking at them from different angles. (Yeah, there's some edge there all right.)
