Idk if there's any part considered spoiler in my text but if so, sorry.

This manga is great....then you finish the first arc. The story start with the revenge plot, where the MC is wrongfully accused and then we follow him on his tragic situation. The thing is, when you're done reading this arc, the rest of story becomes incredibly bland. Except naofumi and his gang, every other character have just no effort put into them whatsoever, more specifically the three other isekai guys. You would think that after the first act, they would have grown or changed or something would have made them more interesting, but no. The story is still enjoyable but its not able to grab your attention as much as the revenge arc. Its still a decent manga but it really let me down.
