    The latter seasons are nowhere as enjoyable as season one. After season one revenge arc the story becomes uninteresting. The second season start is famous for its bad CGI tortoise and I can’t even remember what happened in that arc. Season 3 and 4 introduce new characters, places and power systems and have potential to be good and interesting but plagued with boring character dialogues, unexplained power systems and new places don’t get explored. The worst of all, Naofumi getting a big Harem and that gets in the story.

    That said Season 3 is better than Season 4 and way better than 2 but not as interesting and good as Season 1.
