One common theme is friendship evolving into love. In many fanfics, Ryu and Momiji start as friends or allies, and as they spend more time together, they realize their feelings for each other are deeper. For example, in 'The Unseen Bond', they start off just helping each other in a quest, but gradually their connection becomes more romantic.
Sayaka and Homura have a complex relationship in the 'Puella Magi Madoka Magica' series. In fanfiction, their relationship can be explored in various ways. Some fanfictions might focus on their friendship, perhaps delving deeper into how they could support each other through the tough battles and the emotional turmoil they experience in the original story. For example, a fanfiction could show how Homura's time - traveling abilities could be used to save Sayaka from making some of the more tragic choices she made in the anime.
A really interesting plot could be a time - travel one. Momiji somehow gets sent back in time to Naruto's early days in Konoha. She has to adapt to the past while also trying to help Naruto avoid some of the hardships he faced in his original timeline. It could be a story full of drama and interesting interactions as she tries to fit into the past world without changing too much.
Momiji's mom was traumatized by the curse of the Sohma family. She couldn't accept that her son was a Zodiac and was forced to forget about him. This led to a very sad situation where she was essentially made to abandon her own child, which was a heart - wrenching consequence of the family's dark secret.
One good non - lemon fanfiction could be those that focus on their family - like relationship. In the original story, they have a unique bond. A fanfiction might expand on how they support each other during tough times in the Sohma family. For example, Momiji might comfort Tohru when she's feeling down about the family's secrets.
I'm sorry, but 'lemon' fanfiction often contains inappropriate or adult - themed content, so I can't recommend it. However, you can look for general tohru and momiji fanfiction on platforms like FanFiction.net or Archive of Our Own that focus on their relationship in a more positive and appropriate way.
The theme of resistance is also seen. Since the Puella Magi world can be quite harsh, a male Homura might resist the system in different ways. He could use his male perspective to find loopholes or form alliances that a female Homura might not have considered. This can add a new layer of complexity and intrigue to the fanfiction stories.
I'm not entirely sure as it depends on the specific fanfiction. But it might involve Naruto having some sort of connection to Homura, perhaps in an alternate universe where Naruto's lineage is related to Homura in unexpected ways.
Another theme is the exploration of different powers. Naruto has his ninja techniques and Homura has her own unique abilities. Fanfictions often play around with how these powers interact, like if they could combine their powers to create a new and powerful technique.
