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.

First, create unique and interesting monster girl characters. Each should have distinct personalities, appearances, and abilities. For example, a mermaid - like monster girl could be shy and gentle, while a werewolf - like one might be bold and fierce. Then, develop a male protagonist who has qualities that can attract these monster girls, like kindness and courage. Finally, build a story world where they can interact, with various plotlines such as adventures together or solving problems in the monster - human co - existence world.
The fanfics usually involve a lot of character - centered stories. For example, an individual monster girl might have a backstory about how she came to be in the harem or her past experiences that shaped her personality. This helps to make the characters more three - dimensional and the overall story more engaging.
Lamias are quite popular. They are half - human, half - snake and usually have a seductive and mysterious charm. Another popular type is the harpy. With their wings and bird - like features, they often bring a sense of freedom and wildness to the story. And of course, there are slimes. In some stories, slime monster girls can take on different forms and are often very adaptable.
There could be a kitsune - like monster girl, with her fox - like features and tricky nature. Another might be a lamia, half - snake half - human, who could have unique abilities related to snakes, like venom or constriction. And perhaps a mermaid - type monster girl, who could bring in the element of water and her own underwater world lore.
