Vol 1 is pretty aight, our Mc and friends are pretty chill and wholesome, though I feel like a third of vol 2 onward is what I'm a bit worry about, especially how they will execute them in manga instead, since the premise is good, but because it's a WN, the world building aspect do need a bit of work, and they do need to refine the writing a bit more, the fighting scene is quite confusing to imagine since half of it is just yelling and shouting, but it should be ok when it's shown in manga since we should know who's doing what.
And honestly the 2 reincarnated people beside the MC I've seen in the WN so far for some reasons seem like they haven't touched grass or sunlight for years, I will need to read a bit more to know what the author is cooking with them
