ugh cant stand this, dont want to be known as a saint? then act like one, shes an adult in mind and still acting so stupid by talking about stuff ppl dont know thinking it is nothing important. its kinda annoying tbh
@amc9988 That sounds like every single isekai, to be honest. Some of them actually do bother to point out that having a child's body interferes with your "adult" mind with a bit of age regression and such. Brain chemistry is a thing and all. But the vast majority don't even bother with that, so you can speculate that that's the case, but if it's never stated one way or the other, speculation isn't exactly gonna be a correct answer. It helps to keep it in mind as a way to not get booted in shin by your suspension of disbelief, but it's up to you whether that explanation even works or not in those cases. If you just don't want it to, at all, then most of these stories are gonna have a lot of annoying content like this.
Even setting that aside, you still get the ones where full grown people are isekai'd more or less as is, and they say something like "I don't wanna stand out," so they immediately do just that with their cheat powers.
