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.
When Ayanokoji says 'I'll use any means necessary to achieve my goal', it reveals his somewhat ruthless side. He is not bound by conventional moralities when it comes to reaching his objectives. In the light novel, this could be a result of the cut - throat environment he is in. However, it also makes him a complex character as readers are left to question whether his actions are justifiable or not.
For a 'sunahara wataru sakura fanfic' to be good, it needs to stay true to the spirit of the original while also being creative. It should respect the personalities of the characters. For instance, if Sunahara is known for his humor in the original, the fanfic should incorporate that in a natural way. Additionally, the fanfic should have a clear theme or message, whether it's about friendship, love, or something else, and convey it effectively through the story.
Since I don't know which new novel it is exactly, I'm not sure if there are reviews out there yet. It might be too early for reviews if it was just released.
One of the notable quotes by Ayanokoji from the light novel could be 'I don't care about victory or defeat. What I want is absolute control.' This shows his unique mindset that is not focused on the typical goals of winning or losing but rather on having power and control over situations.
