I would like this a lot more if the Seventh Army wasn't basically just Saitama. Basically all of the characters are pretty likable to me, and that their development is not an issue. I think the story overall is good enough for me to stick around for as long as I've had, and that the pacing of it is just right.
The wars and fights that this has could have so much more impact and tension to them if they just divert the focus from Olivia to the other characters. Instead of showing Olivia killing everything all the time, or Ashton being right about his predictions again, how about we show the privates in the group getting slaughtered or something?
Maybe have one of Ashton's predictions go wrong, creating a disadvantage for the MC? Maybe have someone relatively close to them die, so that there's going to be some shift in their morale? For a team that is composed of newbies, they sure feel invincible. It just feels unnatural for these guys that are so inexperienced to always get the long end of the stick. Granted, I'm reading this as of just finishing chapter 33, so maybe I just haven't caught up to when my complaints get resolved.
I would recommend it, but it's a little boring just constantly watching everyone fucking die because of Olivia.
