So I started reading the light novel and it makes this manga look a lot more kid friendly.
Some changes
1. oscars spirit is a sausage and he says things like "your uncle has a big sausage" which is why they refused to eat it at first (i personally thought it was weird that everyone has a distinct spirit but in the manga wtf is oscars spirit? cause he has tofu, garlic, ect.)
2. Ma Hongjun doesn't need to eat food to satisfy his evil fire spirit... he needs to have sex in the light novel
3. those guys die
There's more but these are some of the changes that I noticed (I'm currently on chapter 58 of the light novel which is the chapter after they kill these guys)
Anyway just wanted to post this so some people know that the light novel is mostly similar but has some very clear differences
