Archive of Our Own (AO3) is also a great place to look. It has a more inclusive and organized system for categorizing fanfictions. Just use the search function and type in'mugen and fuu lemon' to see what pops up.
I'm not sure specifically which mugen and fuu lemon fanfictions are good as it depends on personal taste. However, you can start by looking on popular fanfiction websites like Archive of Our Own. Search for'mugen and fuu' and browse through the results to find ones that seem interesting to you.
One common theme is how they deal with the changes in their relationship. With a pregnancy, their dynamic might shift from just being travel companions to something more parental and committed.
One good example could be a fanfiction where Mugen and Fuu have to face a new and powerful enemy together. This could explore their dynamic further, like how Mugen's brashness and Fuu's determination combine to overcome the foe.
One popular mugen and fuu lemon fanfic might be 'The Adventure of Mugen and Fuu' which focuses on their journey together with a unique plot. However, it can be a bit hard to find really good ones as the fanfic world is vast.
You can start by looking on fanfic websites like Archive of Our Own. They usually have a wide range of fanfics, including those related to Mugen and Fuu.
Another option could be FanFiction.net. However, the search might take some time as you need to filter through a lot of content. But it's also a well - known platform for fan - created stories, so it's worth a shot.
For Fuu, writers may develop her character by putting her in challenging situations. Say, she has to make a tough decision between her own goals and helping Mugen. This would show her growth from the start of the series and how she's become more self - assured and less naive. Also, her relationship with Mugen can be used to show different aspects of her personality, like her patience in dealing with his temper.
Sasuke could be a rival. He's always been competitive with Naruto, and he might see Fuu as an obstacle in Naruto's path. Also, some of the more arrogant ninja from other villages, like those who look down on Naruto's boisterous nature and Fuu's different style of fighting, could be rivals.
I really liked the fanfic 'Naruto and Fuu's Adventure'. It takes them on a journey outside the Hidden Leaf Village. They face various challenges together, and it's really exciting to see how their relationship develops throughout the story.
