One idea could be a story where Crona and Kid are forced to team up on a mission. They start off not getting along because of their very different personalities. Kid is all about order and symmetry, while Crona is more timid and has a darker past. But as the mission progresses, they begin to understand each other better and learn to appreciate their differences.
One great Soul Eater Kid x Crona fanfiction is 'The Bond Beyond Fear'. It beautifully explores their relationship in a post - series setting.

One common theme is the exploration of Crona's journey towards self - discovery with Death the Kid as a sort of guiding or supporting figure. Since Crona has had a difficult past, the fanfictions often show how Kid can help Crona become more confident.
It's the potential for a unique relationship. Kid, with his strict sense of symmetry and order, and Crona, who has been through so much trauma. In fanfiction, they can develop a relationship that is both heart - warming and complex. The fanfic writers get to explore how two such different characters from the Soul Eater universe can come together. For example, they might write about Kid teaching Crona about his ideals of order, while Crona shows Kid the importance of being flexible. This kind of character development in the context of their relationship is very appealing to readers.
In a fanfiction about female Crona, her backstory could be delved deeper. For example, we could see how she was treated in her early days in the world of Soul Eater. Perhaps she had some secret talents that were suppressed because of her upbringing. The story could then focus on her journey to discover and embrace these hidden abilities.
One common theme is the exploration of their relationship development. Since they have very different personalities in the original series, fanfics often focus on how they grow closer. Another theme is the support they give each other. Crona, being more reserved and troubled, often receives emotional support from Kid in these fanfics.
One idea could be a crossover where Sakura Haruno from Naruto somehow ends up in the world of Soul Eater. She could use her medical ninjutsu skills to heal some of the injured students at the DWMA. Maybe she teams up with Maka and Soul to take on a powerful kishin - egg that has some unique abilities related to both Naruto and Soul Eater universes.
One great example could be those that focus on their unique friendship dynamics. In many fanfictions, they start by just being classmates at the DWMA. Then, as the story progresses, their bond deepens through shared battles against the kishin's forces. Another type might explore how Kid's OCD tendencies interact with Crona's more introverted and often confused nature. For instance, Kid might be constantly trying to 'organize' Crona's chaotic life, which could lead to both comical and heart - warming moments.
In some fanfictions, there's an element of self - discovery for both of them. Crona, who is trying to find his place in the world, and Kid, who is constantly trying to uphold his ideals. As they help each other in this journey of self - discovery, their differences become less of a barrier. For example, Crona might teach Kid that it's okay to be a bit more flexible in his thinking, while Kid helps Crona believe in himself more.
