Not a bad read.. Found myself immersed to the storyline, though some scenarios are somewhat familiar already- but I can't really complain.. it's the "Isekai genre" we're talking about here, but maybe.. just maybe.. if it we're to be a little more "realistic" if I should say.. that'd be great, I'm not saying it lack realism.. but maybe it just lacks the certain flair of what reality is, a good example is: Mental shock.., the anxiety, morbidity.., and maybe- a slight drop of human cruelty.. I may not be a writer myself, but this could prove to be a great insight for you.
