One thing that makes me not really like this series... There's no visible romance plot in this story...!! Every fantasy/isekai story wherr the mc have to fight his fate to the end to take back his/her freedom, fighting the evil being that dominate and creating fear on every corner of the world, NEEDS fcking romance plot even if its not harem (though harrm is the best for this kind of story)..!!!
Edit : Sorry, this story has harem but not really visible romance. I want romance if possible harem that created from romance.
