One great fanfiction could be about Death the Kid's adventures with Lemon in a parallel universe where they have to face new types of enemies. Maybe in this story, they discover a hidden power within Lemon that helps them in their battles.
One common theme is the struggle of the OC to fit in. In a world filled with unique and powerful characters like in Soul Eater, the OC often has to prove themselves worthy. And of course, the harem aspect usually involves different types of relationships - from friendship to romantic interests.
One common theme is the clash of cultures. Since Naruto and Soul Eater have different settings and power systems, when combined in a harem fanfiction, there's often a focus on how the characters from each universe react to the other's way of life. For example, Naruto's ninja code might be at odds with the Meister - Weapon system in Soul Eater.
In Soul Eater harem fanfiction, a frequent theme is the adaptation of the original Soul Eater story elements into the harem setup. For instance, the way the concept of souls and the mission to collect them can be intertwined with the relationships in the harem. It could be that a character's soul - related abilities are linked to their relationship with the main character. Another theme is the cultural differences among the harem members, if they are from different backgrounds in the Soul Eater world, and how these differences create both conflicts and opportunities for deeper connection.
A common theme is Crona's self - discovery. In many of these fanfictions, Crona, who is a complex character in the original Soul Eater, goes through a journey of understanding their own feelings, especially in the context of a romantic relationship which is emphasized by the 'lemon' aspect. Another theme is the exploration of forbidden love, as Crona's character has a lot of dark and mysterious elements, and a romantic relationship might be seen as something not quite in line with the norm in the Soul Eater world.
Soul Eater Shaula Lemon fanfiction is unique because it combines the dark and fantastical elements of the Soul Eater universe with the more romantic or sensual aspects of lemon fanfiction. It allows for a different kind of character development for Shaula. For example, we might see her in situations that the original series didn't show, like her dealing with love and attraction in a more adult - like manner. Also, the fanfiction writers often bring in their own interpretations of the Soul Eater lore, which can be really interesting. They might introduce new magical elements or expand on existing ones while still keeping the focus on Shaula's story. Moreover, the lemon aspect can add a layer of emotional and physical intensity that we don't typically get in the mainstream Soul Eater content.
Characteristics could include a more adult - oriented take on the relationships of characters from 'Soul Eater'. However, these types of fanfics are not in line with the family - friendly nature of the original series. They may also take creative liberties with the characters' personalities to fit into the more mature scenarios they are creating.
You can try some popular fanfiction websites like FanFiction.net or Archive of Our Own (AO3). These platforms usually have a wide variety of fanfictions, including those related to Naruto and Soul Eater with a harem theme.
A unique plot. For example, if it takes the character of Evans and puts him in a completely unexpected situation within the Soul Eater universe. Maybe he has to deal with a new type of demon that has a strange connection to his lemon - themed powers (if there were such a thing in the fanfic world).
A unique storyline could be that Lemon has a premonition about a future threat to Death City, but no one believes her except Death the Kid. Together, they start their own investigation, uncovering secrets about the city's past and a conspiracy that could change everything.
