@matrix Had to Google the name to recall it out of the dumpster of isekais that exist and that I've read. I never watched the anime, but from the manga's point of view calling it a pioneer seems like an overstate. It was a fun read though.
As for the sexual stuff, surprising to say, I don't recall that being a focal point in the manga. Not like in the Healer manga anyway.
As for people getting bent out of shape over transmigration: the usual.
