But "Fantasy Bishoujo Juniku Ojisan to" sticks out when you keep reading it. On the surface level everything about it is pretty standard for an Isekai ( minus the gender bender part ) and you might even forget about it after the first chapter. However there is one thing that separates itself from the rest, the comedy.
Everything in this manga is structured to support the comedy. The story makes just enough sense for all the ridiculous things our characters get into, the two main characters are well written to bounce off one another like a slapstick duo, the side characters don't feel one-note; they're actual people, the extras elevate the hilarity of the situation and the art perfectly conveys the punchlines.
This is comedy. So don't take this seriously because the mangaka isn't.
