The exploration of Shizuo's past and how it affects his relationship with the reader is also common. His troubled history might make him hesitant or overly cautious in the relationship at first, but as the story progresses, he learns to open up and trust the reader more, which is a very engaging aspect in these fanfictions.
Another theme is the idea of protection. Shizuo is often depicted as protecting the reader from various threats in the city. This could be from other dangerous characters or just the general chaos of their world. It gives a sense of security in their relationship.
A big theme is also the transformation of the reader's perception. At first, the reader might be scared or wary of Shizuo because he's a vampire. But as the story progresses, they start to see him in a different light, maybe even falling in love with him. There's also the theme of the vampire world itself. Writers often describe the rules, the hierarchy, and the culture of the vampires which the reader has to navigate through.
Another theme is the redemption arc. If one of the characters, say Masaomi, has made some mistakes in the past, the fanfiction might focus on how Shizuo helps him to redeem himself. Or vice versa. This can involve Shizuo learning to control his anger better with Masaomi's influence, and Masaomi becoming a more honest and trustworthy person through his relationship with Shizuo. It's all about how their relationship can be a catalyst for personal growth for both characters.
One common theme is the 'opposites attract' concept. Given their very different personalities, this is often explored. Shizuo's brute strength and hot - headedness contrasted with Mikado's intelligence and calm demeanor makes for an interesting dynamic. Another theme could be the idea of protection. Shizuo might be seen as protecting Mikado from the various dangers in Ikebukuro's underworld.
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.
One common theme could be friendship. Given their different personalities, it's interesting to see how they become friends. Another might be adventure, as they could go on various adventures together in the fanfic world.
One common theme could be family dynamics. Since it involves Shizuo and his little sister, exploring their relationship, how they interact, protect each other or have conflicts can be a central theme.
A common plot element is the initial encounter. It could be a chance meeting in a busy street in Ikebukuro. Another is the OC being in some sort of danger and Shizuo coming to the rescue. For example, the OC might be targeted by a gang and Shizuo uses his strength to protect them.
Well, a great plot for Durarara Shizuo x Reader fanfiction could be set during a festival in Ikebukuro.

Maybe the reader is also involved in some sort of underground activity in Ikebukuro that Shizuo is trying to protect them from, and in the process, they fall in love. It could also be that the reader has a special power or ability that Shizuo discovers, and this discovery deepens their connection.
