In the light novel, Ayanokoji is clearly the more intelligent one. He has a unique ability to analyze situations and people's motives deeply. Ryuen often falls into Ayanokoji's traps because he doesn't fully understand Ayanokoji's true nature. Ayanokoji can anticipate Ryuen's moves and counter them effectively, while Ryuen struggles to keep up with Ayanokoji's complex thinking.
I don't know for sure. The ending of such a manga can be quite unpredictable and might not have been revealed yet. You could try discussing it with other fans to get their speculations.
The dynamic between Ayanokoji and Ryuen in the light novel is quite fascinating. Ayanokoji is the type who operates from the shadows, carefully observing and planning his every move. Ryuen, on the other hand, is more in - your - face with his actions. He is not afraid to make bold moves to gain an upper hand. But Ayanokoji's cool - headedness and strategic thinking always seem to put him in a better position when facing Ryuen. Their battles, whether they are for power or influence within the school setting, are a highlight of the story as it shows two very different approaches to achieving one's goals.
I'm not really sure if they end up together. Different people might have different interpretations. Maybe you can dig deeper into the manga and form your own conclusion.
