I like how it shows just how far above the others the 13 crowns really are and what the power caps of the series are. No matter how powerful you are, something is always better
That's also kinda what I totally disliked about the Gods being introduced and everything around them too. They paint the 13 crowns as so above the rest of the demons but we've seen non 13s do unbelievable levels of power demonstrations and the big three are supposed to be on top of all of that, and even then we've had hint over hint that Sullivan despite the supposed feud over the throne among the three is the one they all think should be there.
And yet we don't see him doing anything in this "Power is everything and the weak must just accept it cuz we're literal demons" land with all this supposed power. What stops him from doing whatever he wants more frequently? If they're suspecting Baal so much why not do more of a demonstration of power? Why are they bound by their laws?
I mean, now they can't cuz that Super Goddess has an eye on him and if they revere them so much then they can't risk angering her, but where's this supposed superiority the rest of the time?
I love the series, but I want a better scale of how far are the strong beings from each other? From our perspective there's no difference between say Naberius' strength and that crown who always seems serious for example. We only know he can't go against Opera and infer Opera probably couldn't go against a crown from how the system's arranged, but we can't see why's that.
We haven't seen what can Opera do that Naberius or Balam can't (only heard them saying they can't go against them), and what can Sullivan actually do (only know he has so much mana he can satiate that Solomon ring).
