Well, no gore except when you see dismembered people hanging from branch and others funny thing from his first "irregular" encounter in the dungeon.
Also, it's surprisingly quite good, and it come from someone who dont like monster card mangas.
This manga is pointless, and the fact that it was a man who reincarnated has absolutely no interest and impact at all.
Seem like more a wet dream from the author.
EDIT chapter 12 : ok, so the man-little girl is a fujoshi now. Just say at start he was gay or trans, why all the crappy premise.
