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.
One possible theme is the loss of self - control. Shizuo's uncontrollable anger and Izaya's inability to stop his manipulative ways can be central to the sad fanfic. It can show how these traits lead to their downfall or at least a continuous cycle of unhappiness. Also, the theme of unrequited understanding could be present. They seem to misunderstand each other constantly, and in a sad fanfic, this lack of understanding could be the source of great sorrow as they keep missing the chance to connect on a deeper level.
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.
Well, in general, Shizuo is often depicted as the strong and hot - tempered one. In fanfiction, he might be shown as being very protective or possessive in a relationship with Izaya. Izaya, on the other hand, is usually the sly and manipulative character. In such fanfictions, he may use his wits to either get closer to Shizuo or drive him crazy. But remember, lemon fanfiction often has inappropriate content, so this is just a general view of how they are typically characterized in more appropriate fanfictions about them.
Another theme is the exploration of an unlikely relationship. Since Shizuo is such a complex and often violent character, seeing him interact with an original character creates a unique dynamic. It's about two different worlds colliding, like in some fics where the OC is from a completely different background than the Durarara world.
There are also fanfictions that explore their backstories in relation to each other. Maybe a story about how Mikado first heard of Shizuo and was both intrigued and a little scared. As the story progresses, they could meet under strange circumstances and start to build a connection that was not originally expected in the Durarara series.
It's also the potential for their relationship to develop in different ways. In fanfiction, we can see them go from enemies to something more, like friends or even lovers. Writers can explore different emotional aspects of their connection, which is really fascinating. For example, how they might come to understand and accept each other's differences over time. Another aspect is that the 'Durarara!!' series, from which these characters are from, has a large and dedicated fanbase. So, fans are eager to see more of these characters in different scenarios, and fanfiction provides that opportunity.
Character development is a major element. With Izaya as female, her character can be re - imagined in many ways. She could have different motives, insecurities, or goals. And for Shizuo, his reactions to this new Izaya can also show a new side of his character. Also, the setting often plays a role. Some fanfictions might change the setting slightly to better suit the new relationship concept, like a more romantic or mysterious setting.
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.
Another challenge is the world - building within the fanfiction. Since this is a rather unique and unexpected plot, the writer has to create a believable scenario in which this could happen. They might need to consider things like the society in which these characters exist, how their friends and family would react, and what kind of medical or magical explanations (if any) would be used. It's not easy to blend this out - of - the - ordinary plot into the existing lore of the original work.
The Durarara universe is already filled with so many complex relationships and subplots. When you focus on Shizuo and Mikado in fanfiction, it allows the author to explore new angles within this rich world. For example, they can be involved in the underground activities of Ikebukuro in ways that were not fully explored in the original series. This gives the readers a fresh perspective on the story and the characters.
One great 'female Izaya x Shizuo fanfiction' is 'The Unlikely Bond'. It delves into how their relationship could develop in a unique way with Izaya being female. The character interactions are really interesting as it shows a different dynamic between them compared to the original series.
