Add to that as other reviewers have mentioned the fact the rules are one-sided, poorly explained, there are no 2-way negotiations on setting up the rules til the final battle, the fact the people don't know what they are getting themselves in for as not much is ever explained. We also add this anime seems more to serve the mail audience even with tropey characters which almost felt like watching the later arifureta which copied the same tropey bunny, loli vampire, etc.
It just felt the same nonsense that's been growing for a long time in Anime and Manga as writers just keep trying to feed a braindead market. I say is aimed at guys, between the Bunny being there for fan service and both vamp loli and goth loli, add to that the difference in strength between the guy and the two girls, who seemed to be there for chance romantic interest down the line
We see nothing really new here, nothing special, so how this anime gets such a high rating I never know. Even the art was disappointing to me, and it maybe the fact that the animes about 10 years old nearly, The anime just became predictable since the water god fight and then the second fight, set a clear pecking order. It is just one of the animes, to fill a hole in the day, it sits between bag and average, much to my slightly expected disapointment
