A common theme is friendship. Kimihito and Lemon often develop a strong bond of friendship in fanfics. They support each other through various situations. Another theme is acceptance.

One popular type of Monster Musume fanfic with Kimihito Kurusu might involve his daily adventures with Lemon. Maybe it shows how they interact in a new situation in the household. For example, a fanfic could be about them dealing with a new monster girl arriving at the house and how Kimihito and Lemon cooperate to make her feel welcome. Another aspect could be fanfics that explore the relationship between Kimihito and Lemon in a more emotional depth, like when Lemon has some personal problems and Kimihito helps her through it.
It's hard to say it's a widely popular genre. 'Monster Musume' itself has a dedicated fanbase. But when it comes to 'harem' and 'lemon' elements in fanfic, these can be polarizing. Some people might be attracted to the idea of a harem in the Monster Musume setting, but the 'lemon' part can be off - putting to many. So overall, it may not be as popular as more general Monster Musume fanfic.
One common theme is friendship. Papi's character often forms strong friendships with other characters in the fanfic. Another theme could be adventure, where Papi goes on exciting journeys with her companions. And of course, there's often a touch of romance as well, exploring her relationships in a different light.
One interesting aspect could be the unique character interactions. In Monster Musume fanfics, the different monster girl species bring diverse personalities and cultural backgrounds, which can lead to really engaging and sometimes comical exchanges. For example, a lamia might have a different view on relationships compared to a harpy. Another aspect is the exploration of new storylines. Fanfic writers often take the basic premise of the Monster Musume world and create their own adventures, like the monster girls going on a quest together. It also allows for a deeper look into the emotions of the characters. Since the fanfics can focus more on individual character development, we can see how the monster girls and human characters deal with things like love, friendship, and acceptance in more detail.
Smith Lemon is surely a main character. Then, depending on the fanfic's focus, it could be a mermaid - like monster musume. She could bring a sense of mystery as she is from the underwater world. There might also be a centaur - type character who is strong and has a noble personality. All of these characters, along with Smith Lemon, would play important roles in the story, each with their own goals and personalities that collide and interact.
Yes, there can be many interesting plots. For example, the unique relationships between the different monster girls and the human characters. It might explore how they interact in a world where humans and monsters coexist, like how they deal with cultural differences or how they form friendships and romances. The fanfic could also introduce new adventures that the characters go on together, facing challenges and growing as a result.
Another theme is the integration of the monster girls into human society. It could be about how they adapt to human customs, go to school or work, and deal with the prejudices and acceptance of humans. These types of fanfics often explore deeper social and cultural aspects.
