Many female Izaya fanfictions have the theme of redemption. They might show Izaya as a character who is capable of change through his interactions with female characters. Or it could be the other way around, where the female characters are the ones in need of redemption and Izaya plays a role in that process. There's also the theme of the 'outsider' as Izaya often seems to be an outsider in the Durarara!! world, and female characters may share or oppose this aspect of him.
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 common theme could be self - discovery. Since Izaya is a complex character, a female version might also go through a journey of understanding herself.
Another theme is the exploration of Izaya's new identity. As a girl, she may face different challenges and opportunities. Fanfictions often explore how she copes with this new gender identity in the world she exists in. For example, she might use her femininity in different ways to achieve her goals compared to when she was male. This can add a whole new layer of complexity to her character.
One common theme is the exploration of Izaya's charm from a female perspective. Female characters are often drawn to his mysterious nature.
One common theme is the clash of personalities. Izaya has his own unique and often devious ways, while the Mikage family has their own values and family dynamics. Another theme is the exploration of family bonds. How Izaya either disrupts or becomes a part of those bonds is often explored.
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.
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.
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.
Celty might also interact with him. She's often involved in the events of the series. A drunk Izaya could be a source of confusion for her, or perhaps she would try to help him in some way, seeing as she has a kind heart despite her rather spooky appearance. Another possible character is Namie. Since she has a complex relationship with Izaya, she might be the one to find him drunk and have to deal with the consequences, whether it's covering for him or using his drunken state to her advantage.
One main theme could be the complex relationships between characters. Izaya and Namie likely have a dynamic that involves mystery and intrigue. Another might be the exploration of their individual personalities, as they are probably distinct and interesting in their own ways.
