I don't really understand the bad reviews, I had paused at episode 1 which disappointed me a little and I chained from 2 to 6 and I don't think this anime deserves a score of 5, it's an average Isekai like reincarnated with my smartphone I think people have too much expectation, the anime totally fulfills its role of seasonal isekai, The only three big negative points that I noted: -A development very focused on his still human past in the first two episodes which for the moment brings absolutely nothing to see if it is used later. -The story advances much too quickly one would say thatit condenses everything at full speed to quickly reach the end of the anime.

-Aku has become completely forgotten except for a few quick appearances while she had a main role in season 1 and it's sad :/

Otherwise the anime is really good for an average Isekai it clearly deserves a rating between 6 and 7!
