Noel's stance on the brewing coup reminds me of the US pre-Pearl Harbor. Supporting the Allies with material supplies, but no troops until directly attacked. Except he won't get caught by surprise unless it's a betrayal.
I don't care that he's not scrambling to help the coup or anything, I know for a fact he doesn't see himself as the "hero" anymore and he is not the Lawful Good hero other commenters want him to be, which they just cannot accept. Man wants to be True Neutral, I'd say let him. He's strong enough to afford it and protect the friends around him. Is it selfish? Sure, but he doesn't owe that rotten kingdom anything after all that's happened. Neither does he owe the coup plotters who want to destroy the kingdom, although there are long-term benefits to helping that side.
It's like if Clark Kent decided not to continue being Superman after permanently beating the big bad and just settle down in his hometown to be a farmer instead. It's an interesting take, and I appreciate how things in this world are not really all black and white, simple good or evil. Flio from
Lv2 kara Cheat datta Moto Yuusha is another example of a protagonist not being the Lawful Good superhero, just a neutral (OP) guy wanting to live peacefully with his friends and family.
But oh man, this lazy writing LOL. Just when they had a need for something, instead of having someone train or learn to fill the role, it just introduced a new haremette instead. Need some skill? Here's a new girl, instant expert.
I don't suppose this will just introduce a new girl for each need they have? Sounds ridiculous but I guess it's a bit better than just having the male lead suddenly become a competent expert in certain fields as needed. Can't be worse than "his powers are based on need".
