What stands out with this isekai compared to most is how literally everyone in the world is an idiot. The MC refuses to tell anyone what his stats are even though that would solve all of his problems. Virtually everyone else in the world assumes he only has evasion (despite seeing him healing people and putting up shields and shit) and immediately dismisses him as useless despite seeing physical evidence to the contrary. But this has been the case from the start. This Daia guy is a new kind of stupid where he knows for a fact that the MC is virtually invulnerable to damage, but in his brain "healer = rearguard = vulnerable", and seeing a counterexample has apparently caused his brain to bluescreen, so now he screams at him for pulling aggro even though he knows that will not put him in any danger. It's just an endless parade of stupid.
