Often, there are themes related to power and empowerment. Since Allen Walker has certain powers in the original D. Gray - man series, as a female version, she might face different challenges and opportunities regarding her powers. There can be a theme of self - discovery too. The female Allen Walker might question who she is in this new form and how she fits into the world of the story. Also, themes of friendship and loyalty are common, as she interacts with her friends and allies in new and different ways.
One common theme is the exploration of different relationships. For example, how the female Allen Walker would interact with other characters in a more romantic or platonic way. Another theme could be her struggle with her identity, given the change in gender. It might also involve her dealing with the same dark and supernatural elements as in the original story but with a different perspective as a female.
Love is a very common theme. It could be a slow - burning love or a love at first sight between the reader and Allen. Another common theme is adventure, as Allen is often involved in dangerous and exciting situations, and the reader gets to be part of those. Also, friendship is a theme, as the relationship might start as friends and then develop into something more.
