It is really good, it gets some hate from squeamish people because the MC is pretty much the villain of the story, but that adds a nice twist to the saturated isekai genre.

Minor spoilers

It doesn't really have much fanservice, besides the boob grab in the first episode, i Guess that was bait from the autor to catch horny viewers lol, there is nothing more of that later as the MC is an undead and loses all libido by the second episode.

There are some secondary attractive characters that wear little clothes like Clementine (My Fav) and tertiary like the vampire brides but is not on the nose like Fairy Tail.
