Another plot could be that the reader is an outsider to the world of Soul Eater, perhaps from a different dimension. Soul accidentally discovers the reader and at first is suspicious. But as he gets to know the reader, he realizes that they are kind - hearted. They then have to deal with the challenges of the reader adapting to the Soul Eater world while also falling for each other.
One idea could be the reader being a new student at the DWMA. They could struggle to find their weapon partner at first, but then end up with an unexpected and powerful weapon. Another plot could involve the reader having a special ability that draws the attention of the Kishin's minions, leading to various battles and the need for protection from the main Soul Eater characters.
One plot idea could be that the reader is a new student at the DWMA and Stein takes them under his wing as an apprentice. As they work together, they start to develop feelings for each other. Another could be that the reader has a special power that Stein is intrigued by and he tries to study it, which leads to them getting closer.
One idea could be an OC who has a unique weapon form that no one has seen before in the Soul Eater world. For example, an OC that can transform into a musical instrument like a harp that has the power to soothe or disrupt souls. Another plot could involve an OC who is a transfer student from a far - off place with a different type of soul wavelength training, and they have to adapt to the DWMA's methods while also teaching the others something new. A third idea is an OC who has a connection to a powerful and ancient soul that starts to cause problems as the story progresses.
A third plot idea could be the reader being a time - traveler from the future. They come to the present in the Soul Eater world to prevent a great disaster that will happen if certain events aren't changed. The reader teams up with the main characters, using their knowledge of the future to help them in battles and make strategic decisions. This would involve a lot of adventure, mystery, and the building of relationships between the reader and the Soul Eater characters in a non - inappropriate way.
One idea could be a story where Death the Kid has to team up with a character from Soul Eater to face a new, powerful enemy that threatens the balance between the world of humans and the world of demons. They might start off not getting along due to their different personalities and ways of doing things, but as they face challenges together, they learn to respect each other and combine their strengths to defeat the foe.
One plot idea could be that Eruka somehow gets transported to the world of Free! and has to adapt to the new environment. Maybe she meets a character from Free! who is intrigued by her magic abilities from Soul Eater.
One plot idea could be Tsugumi and Akane having to team up for a special mission in the Soul Eater world. They start off not getting along well but as they face various challenges, like powerful kishin eggs, they gradually develop a deeper understanding and friendship that could potentially turn into more. Another idea is a time - travel plot where they are sent back in time and have to rely on each other to get back to their own time while also learning secrets about their families' pasts in the Soul Eater universe.
One great Crona x Soul fanfiction is 'The Bond Beyond'. It delves into how Crona and Soul's relationship develops in a more in - depth way than in the original series. It shows them learning about each other's pasts and how they grow together. Another one could be 'A Different Kind of Friendship'. This fanfiction focuses on how they start as friends but there are hints of deeper feelings emerging as they face various challenges in the world of Soul Eater.
One idea could be a story where the main character discovers a hidden power within their soul that has the potential to either save or destroy the world in the Soul Eater universe. They then have to struggle with the moral implications of using this power.
Maybe an OC that has a special ability related to time. They can slow down time briefly during a fight. But this power comes with a cost, like it drains their soul energy quickly. The fanfiction could explore how they learn to control this power and balance its use while also dealing with the normal challenges at the DWMA, such as making friends and passing classes.
