I really like 'Remus Lupin's Unlikely Mate'. It's a story that takes an unexpected turn in terms of who his mate is. It has a lot of adventure in it. Remus and his mate go through various challenges together, which makes their relationship more believable and engaging.
One key element is the clash of their personalities. Sherlock is highly logical and methodical, while Lupin is more of a charming trickster. Their different ways of approaching problems make for interesting interactions. Another element is the mystery aspect. Usually, they are involved in solving some complex cases together. And of course, their relationship development, whether it's from being rivals to allies or something more complex.
One great 'Sherlock x Lupin' fanfic is 'The Meeting of Minds'. It beautifully weaves the deductive skills of Sherlock with the cunning nature of Lupin. Another interesting one could be 'Sherlock and Lupin: Unlikely Allies' which shows their unique relationship development. There's also 'In the Shadows of Baker Street' where their adventures together are quite thrilling.
Adventure is also a prevalent theme. Since they are thieves in the Lupin III universe, they are often on exciting adventures in fanfics. Whether it's stealing a precious jewel or outwitting a powerful enemy, adventure is at the heart of many of these stories.
One common theme is mentorship. Lupin, being a teacher, often acts as a mentor to the student in these fanfics. He guides them through their studies and personal growth.
In such fanfiction, one aspect could be the exploration of their opposing natures. Remus Lupin, a werewolf trying to control his condition, and Fenrir Greyback, a werewolf who embraces his savage side. The fanfiction might delve into how their interactions could be full of tension, as Lupin represents the civilized werewolf while Greyback is the wild and dangerous one.
One great lupin x jigen fanfic could be a story where they go on a heist together in a fictional city filled with high - tech security. They use their unique skills, Lupin's charm and Jigen's marksmanship, to outwit the bad guys and steal a precious jewel.
One key element is the exploration of Remus's dual nature. Since he's a werewolf, it often plays a big role in how he interacts with his mate. For example, in some fanfictions, his mate has to deal with his transformations.
One common theme is mentorship. Lupin often acts as a mentor to the student, guiding them through their studies or personal challenges. Another theme is the discovery of self. The student may learn a great deal about themselves through their interactions with Lupin. Also, the theme of acceptance is prevalent, especially when it comes to Lupin's lycanthropy. The student may come to accept Lupin for who he is, and this acceptance can be a turning point in their relationship.
Some popular ones often involve the unique relationship between Remus and the reader. They might include scenarios where the reader helps Remus deal with his lycanthropy, like in 'Moonlight Encounters' which delves into how the reader supports Remus during his transformations. Another could be 'Remus' Secret Admirer' where the reader secretly loves Remus and the story unfolds as they gradually come closer.
