Friendship is a very common theme. Since they are both characters from the same universe, their friendship often forms the basis of many fanfics.
Common themes could include friendship, loyalty, and the development of a special bond between Erza and Mira.
Adventure is also a popular theme. They might embark on quests or explore new places together. Like in some fanfics, they travel to uncharted regions to find a lost artifact or solve a mystery. This allows for a lot of exciting plot developments.
One common theme is the clash of different cultures. Naruto comes from a world of ninjas with its own set of values and traditions, while Mira is from her own distinct world. So, there's often exploration of how they deal with these differences.
One common theme is growth. Both characters are often shown to grow as individuals and in their relationship with each other. For example, Mori Jin might learn more about patience from Mira, and Mira could learn about taking risks from Mori Jin.
