There's also 'L and Misa: A Different Perspective'. This fanfic delves deep into their characters. It explores how Misa's adoration for Light affects her relationship with L. It's really interesting to see how L tries to understand Misa's motives and how she might be a key in his investigation.
One common theme is the clash of different worlds. For example, when L crosses over into a fantasy world, his scientific and logical mindset is at odds with the magic or other non - scientific elements of that world.
It could be a rogue detective who is jealous of L's fame and abilities. This detective might think that by kidnapping L, he can take over the high - profile Kira case and prove himself to be better.
One common theme is the exploration of L's more private and emotional side. Since he's such a mysterious character in the original, fanfictions often delve into his feelings. Another theme could be the forbidden or secret relationships he might be in, which ties into the 'lemon' aspect, like a relationship with someone he shouldn't be involved with in the context of the Death Note world.
Another theme is the exploration of their personalities. Misa's bubbly and somewhat naïve nature contrasts with L's cold and calculating demeanor. Fanfictions often play with how these two personalities clash and sometimes, surprisingly, complement each other. For example, in some fanfics, Misa's unpredictability helps L in his investigations in unexpected ways.
One common theme is the exploration of L's hidden emotions. Since L is such an enigmatic character in the original, fanfictions often try to dig deeper into his feelings, especially when it comes to romantic or more intimate relationships. For example, his struggle between his logical mind and new - found emotional desires.
Love in an unlikely situation is also a common theme. Given L's unusual personality and lifestyle, it's interesting to see how a relationship could develop between him and the reader - character. It's often a slow - building love, as L isn't the type to fall easily. Writers explore how love can grow in the midst of his high - pressure world of chasing Kira and solving complex crimes.
One common theme is the battle of wits. Since Death Note is all about mind games, the OC often gets involved in trying to outthink Kira alongside L. Another theme is the development of an unexpected relationship. L is such an aloof character, so seeing how an OC can break through his barriers is a popular plot point.
