This is such a dog eat dog world, but not in the way that where everyone is comically evil for no reason whatsoever. This is just a world where there's a reason as to why everyone is the way they are, but at the same time they're also just always trying to put themselves first before anyone else. You still have good people like the blacksmith siblings that Yajin befriended (which I'm so grateful for because Yajin really needs people he can trust and have a healthy relationship with), and I'd venture to say that the sword saint was a good person too. The guard here as well. This world is more realistic, many people trying to do what they can to survive, even if it means taking advantage of other people, but the world isn't without their more altruistic and good people as well. A lot of grey areas.
