Some fanfictions explore the theme of sacrifice. Ash is often portrayed as someone who is willing to sacrifice himself for Eiji's safety or well - being, and vice versa. This theme adds a layer of drama and intensity to their relationship. Additionally, there are fanfictions that focus on their cultural differences, as Ash is from a very different world than Eiji, and how they navigate and learn from those differences.
One common theme is friendship. Their bond is often explored in different ways, like how they support each other through tough times. Another theme is sacrifice. Ash, in particular, is often portrayed as being willing to sacrifice a great deal for Eiji.
