Another theme is redemption. Some fanfics explore the idea of whether the Kishin can be redeemed or not, and the reader is often involved in this process. It's about exploring the good and bad sides of such a complex and usually villainous character. There are also themes of friendship and betrayal. The reader might form an unexpected friendship with the Kishin or be betrayed by it, adding a lot of drama to the story. This is because the relationship between a human - like reader and the Kishin is full of potential for different kinds of emotional and plot - driven interactions.
One popular Soul Eater Kishin reader fanfiction is 'The Kishin's Apprentice'. It has an interesting plot where the reader character is drawn into the world of the Kishin in a rather unexpected way. The story is full of action and some really cool character interactions.
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.
I think it is. The plot has depth, the action scenes are exciting, and it has a good mix of humor and drama. However, it might not be for everyone depending on personal preferences.
