If this was meant to be a parody of sorts of the genre, then the only thing I have to comment about is that the old-man persona completely took over the "villainess" identity. If you happened to recall your previous life, your current-self wouldn't be completely overridden. That's just silly.
And, again, that's only a complaint if this story was actually meant to present the perspective of someone who's outside of the genre. Otherwise, lolderp isekai is lolderp isekai.
