Well, it depends on the specific fanfiction. There are many different interpretations of Harry in the fanfiction world. Some authors might give him a perfect memory to enhance his abilities and make the story more exciting. For example, he could remember every little thing from his past encounters with Voldemort, which could help him anticipate his enemy's moves better.
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.
The development can also be based on personal growth. Horikita is often very focused on her own goals and can be a bit cold. Ayanokoji could be the one to help her see the importance of relationships. Maybe he shows her how a more empathetic approach can help in achieving their class's success. This would lead to Horikita opening up to him more, and Ayanokoji in turn would start to show more of his true self to her. Over time, a deeper relationship could form as they both grow as individuals within the context of the fanfic.
Well, having a perfect memory means Harry can remember every conversation he's had. This could be crucial when trying to figure out hidden meanings or secrets. He can remember the exact words of prophecies, which could help him better understand his destiny. Moreover, he can remember the layout of places he's been to, like the Forbidden Forest or the secret passages in Hogwarts, which could be useful for escaping or finding something important.
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.
😋I recommend the following novel to you:
"The Strongest Exchange System in History","The Heavens Begin from the Perfect World","Crossing the Heavens from the Perfect World","The Supreme Ruler of the Perfect World","The Light Immortal Emperor of the Perfect World","I Open a Bookstore in the Other World","The Perfect World: Reviving the Earth Spirit and Raising the Willow God's Wife","Immortal Martial War Emperor","The Beginning of the Perfect World","The Saber Emperor of the Perfect World","The Perfect World: Entering the Primordial Azure Dragon Body","The Ancestral Dragon of the Perfect World". These novels were all fantasy or oriental fantasy novels, covering many planes and worlds. Some could even travel to the worlds of other novels. I hope you like this fairy's recommendation. Muah ~😗
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.
