There's a fanfic titled 'Akira and Ryo: A Different Path'. In this story, it takes a more alternate universe approach. Instead of the tragic events in the original, they end up on a journey together to discover a new way to coexist with the demons. It's a really interesting take on their relationship as it shows them growing closer in a more positive environment.
Well, in many of these fanfictions, the character development of Alice and Ryo is quite interesting. The authors often give more depth to their personalities. For example, Alice might be shown as more vulnerable in some stories, while Ryo could be portrayed as having a softer side. It's also cool how different fanfiction writers can create different scenarios for them to interact, like in a cooking competition held in a foreign land.
