It behaves like science in volume 1, but in volume 2, it shows that Otherworlders can use their Concepts to make it behaves like magic. In volume 4, it reveals that the thing called Guiding Force is a system that written to the world. You can use Concept to write more laws to it, like sacrificing Time Concept to create Time Guiding Force. Also, since the Church is on top of the food chains, the rebellion has to borrow power from Human Errors to fight against them.

Akari is an air-head because she brainwash herself with her power. Even if she does not do that, she still retains half of the air-head since she loses her memories already. Later on she could think outside-of-the-box because she has experienced to this journey many times. Menou is still a dark tragedy hero at volume 4, but she likely changes since the reason why Akari loses her memory comes from that characteristic. Even the old lady villian is revealed to commit her taboo because of the true nature of the Church as well.

The world is very adaptive. It centrals around the Otherworlders with their Concepts, so everything seems pretty fake. Most of things are attached with details like "oh this comes from Japanese culture" and the character will talk about other things.

First, we have a cringe tragedy hero who wants to be a savior but keep telling herself she is a villain. Then, we have anime magical girls with over-the-top attitude. Next, some realistic world building is added to the mix. Then, at the end, cartoonist villian appear and it turns out everybody is insane in this story. The next volume continues exaplain why everyone is f*cked up like that and throw in some weird things. It keeps go on and on and soon you will be hooked to this kind of chaos.
