One great Soul Eater Kid x Crona fanfiction is 'The Bond Beyond Fear'. It beautifully explores their relationship in a post - series setting. The author does an amazing job of delving into Crona's insecurities and how Kid's presence helps them grow. Another good one is 'A Different Kind of Connection' which shows their relationship from a more comical side at first but then develops into a deep emotional bond. There are also some on Archive of Our Own that are worth checking out if you like this pairing.
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.
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.
One key moment could be when they first fight together side by side against an enemy. It's a moment of trust building. Another is when Death the Kid shares his thoughts about symmetry with the Reader. It shows his vulnerability. And of course, the moment when they finally admit their feelings for each other is crucial.
