I might be taking them too lightly but it's pretty easy to bullshit since we never saw them get off their ass to do anything. It's always aura farming with them, never a single feat that's not acted out on the stage.
Maybe the only way for him to look strong is by designing his wins beforehand. Maybe he's not even Opera level, he's just a fraud who can't win without a cool weapon to amplify his power, Kriwio style
I'm really wondering why is it even that big of a deal. Sure Narnia and Baal are strong but like, 70% of all nether authority is live or die for Iruma. Nightwalker lost to a freshly graduated Henry, Opera can knock out Kalego in one punch, Narnia got bitch slapped by the head of lust.
Even if Nightwalker went out and used his maximum power, he's not making it past Ameri, especially in his weak ass wheelchair state.
I can't speak about Baal since we never saw him fight anything except a modified Behemolt but 90% of the story is just him sitting all sassy and serving cunt occasionally. I really don't think he can do much without his spear he threatened his brother to have.
The only real person that poses a threat is the deity but she shouldn't be that blindly stupid to turn a blind eye to the entire nether rising against Baal. Why would she even have that much authority if she's that naive enough to fall for a gay man.
