I'm frustrated that the new manga has lots of red flags which smell of axe or low sales dragged out til chapter 50. First he put his big girl fetish in again in the first chapter prominently. People are going to be turned off early on. Then there are lots of little things I could say but mainly: regardless of the setup it feels like the kid gets a magic sword that can take out a huge monster kani for no reason. This is not even near the same tier of "undeserved" as Boku no hero. Also just inconsistent feeling writing like the whole story we see him wanting to be part of a heroic tale and then in a near climactic moment he says "I don't care if I go to Valhalla" etc. I just want to save everyone. Which could be a good character moment but instead just feels like he's indecisive and not committed. If you're going to spend that long on certain aspects of his character it would have been better to just give it a straightforward payoff. He should have just gone "I WILL save everyone AND be a hero etc."
His editor is probably new. I wonder who it is. There's some editors that I have a hateboner for, I'm assuming it's one of them.
