I was totally ready for them to get wiped in the dungeon just like in every other standard fantasy manga. But as usual, Mushoku Tensei shirks convention, and I appreciate that a lot.
Instead of everyone dying, they explore a more human element of these characters. Putting his death there right after Roxy had placed all of her faith on him is impactful and tragic.
This series almost singlehandedly proves that the isekai genre can be well-written.
