This show could have been some quality isekai slop for people who like the generic power fantasy. It suffers from the same issues of bland characters and oversexualization you would see in any of these shows, but the action is well done. It also doesn't really go anywhere with the plot and has some very strange stuff that feels like the author satisfying a pregnancy fetish. All of this could be forgiven as quirks of the genre, except for one glaring issue:
The main character is literally a r*pist and this is presented as nothing at best or a joke at worst. It's absolutely disgusting and makes the show entirely unforgivable. How can you be expected to root for a protagonist that's so awful? There's nothing graphic, but the implications alone say everything I need to know about the writers.
