I think I like how the author stretched the idea of "kids or teenagers suddenly picking up on others" and combined it with psychopathic tropes.
Same goes for like 90% of the movies out there. Love the idea how advanced alien civilizations are all using the same type of UFO look the same and have the same goal: to eradicate humanity. Love the idea of how we are stretching the whole idea about tricks and stuff into the whole magic with mana and element. Love how authors stretch the idea how demons can be both kind and evil and etc. It's a fiction. It's not documentary.
You would think that the asshole that was throw off a cliff in front of a car would resent the other kid if not just straight fear him, but he seems fine while he mauls the lil bro with a rock and burns down the car?
