Bro relax, don't spoil me. But I'm ngl the only reason I kept watching Mid Slayer was because there are real stakes and tension in the fights once you run into an upper demon, like these dudes are legitimately overpowered and for good reason. I hate shows where they try and make humans on par with opponents who have access to things like regen and other super powers. Hashira are nothing compared to upper demons, and the author does not care for plot armour when it comes to facing them, you will get mogged, doesn't matter who you are. Mugen train was the first time we learned this.
That is the single thing that sets demon slayer apart from every other battle shounen, other than this it is literally a story written by chatgpt. I didn't fully realize why I was still watching this mid series and then it hit me, when an upper demon shows up shit gets real.
