Well, it could be really interesting. Izaya Orihara is known for his mischievous and manipulative nature in 'Durarara'. In a 'Harry Potter' setting, he might be a slytherin, using his wits and charm to get what he wants. He could be a fan of the magical world, perhaps fascinated by the power of magic and the complex social hierarchies within Hogwarts. He might try to insert himself into the wizarding world's affairs, causing chaos and confusion among the students and teachers alike.
If there was such a fanfic, Izaya Orihara could be a fan of the Harry Potter series in a really unique way. He might see the magical world as another playground for his schemes. Maybe he'd befriend some of the more rebellious characters like Fred and George Weasley and together they'd come up with all sorts of pranks. Or he could be intrigued by Voldemort's rise to power and try to study the dark arts from a different perspective, all while being a character who is out of place in the wizarding world but still manages to make an impact.
In a 'Durarara' and 'Harry Potter' fanfic where Izaya Orihara is a fan, he could bring a whole new dynamic to the story. He might start by observing the different houses in Hogwarts and trying to figure out how to manipulate the students based on their house traits. For example, he could use the Gryffindors' bravery against them by daring them into dangerous situations. He could also be interested in the Forbidden Forest and the creatures within it, seeing them as potential tools for his own amusement. His presence would likely disrupt the normal order of things at Hogwarts, creating a story full of twists and turns as the students and teachers try to deal with this strange new character in their midst.
I'm not sure if there is such a specific fanfic. There are countless fanfics out there, and while crossovers between different series like 'Durarara' and 'Harry Potter' are possible, and a character like Izaya Orihara being a fan in that context is a very niche idea. It would be quite difficult to find without extensive searching through various fanfic platforms.
Another theme is self - discovery. The OC often goes through a journey of understanding themselves better while being involved with Izaya. They might learn about their own strength, weakness, or hidden desires. It's like the relationship acts as a catalyst for their personal growth. For instance, in some fanfics, the OC discovers a more assertive side of themselves because of their interactions with Izaya.
One possible aspect to analyze in this fanfic could be the complex relationship between Izaya and Shizuo. Their interactions are often filled with tension and animosity in the original work. In a sad fanfic, perhaps it delves deeper into the unfulfilled aspects of their relationship, like how they might never truly understand each other despite their many encounters. It could also explore how their individual traumas and personalities contribute to the overall melancholy tone of the story.
One of the main themes is the complexity of human nature. Izaya is a character who manipulates others, and through his actions, we see how people can be both good and bad, and how easily they can be influenced. Another theme is the concept of chaos and order in a city like Ikebukuro, where Izaya's actions often stir up trouble and disrupt the normal flow of things.
One common theme could be self - discovery. Since Izaya is a complex character, a female version might also go through a journey of understanding herself.
Loneliness could be a major theme. Both Izaya and Shizuo seem to be isolated in their own ways. Izaya's devious nature and Shizuo's violent outbursts keep others at a distance. In a sad fanfic, this loneliness could be emphasized, showing how they are unable to find true companionship. Another theme might be the futility of their conflict. They keep going at each other, but it seems like there's no end or resolution in sight, creating a sense of despair.
There's also 'Izaya and the Unlikely Companion'. In this fanfic, the OC is an artist who gets caught up in Izaya's world. The story is great as it shows how their different worlds collide and how they gradually understand each other more. It has some really well - written dialogue that brings the characters to life.
Another good place could be FanFiction.net. Although it has a broader range of content quality, there are still some great Heiwajima Shizuo x Orihara Izaya fanfictions there. Browse through the relevant categories or use the search bar to narrow down your search. However, be prepared to sift through a lot of content to find the gems.
One common theme is the mystery around Izaya. Female characters are often intrigued by his complex and somewhat devious nature. They might try to figure him out, which leads to interesting interactions.
One popular Izaya Orihara light novel is 'Durarara!!'. It's a great read as it delves deep into the complex character of Izaya. The story is set in Ikebukuro and is filled with various sub - plots and interesting characters that interact with Izaya in different ways, making for a very engaging narrative.
