Friendship across universes is also a popular theme. Naruto and Rukia come from different fictional universes, so the idea of them forming a strong bond despite their differences is often explored. They learn from each other's values and ways of life, like Naruto teaching Rukia about the importance of never giving up in the face of adversity, and Rukia showing Naruto the more spiritual side of things.
Another theme is the exploration of new worlds. Fanfictions often take the characters on adventures in each other's worlds. So we might see Naruto exploring the Soul Society or Rukia experiencing the Hidden Leaf Village. This allows for a lot of world - building and discovery within the fanfiction.
One common theme is the 'opposites attract' concept. Naruto is very energetic and loud, while Rukia is more reserved. Another theme could be about them overcoming differences between their two worlds. For example, Naruto's ninja world and Rukia's world of spirits.

Self - discovery is another theme that could be present. Rukia might be on a journey to understand herself better, her powers, and her place in the story's world. This self - discovery can be intertwined with the relationships she has in the fanfiction.
Another theme is isolation. The dark circumstances might make Rukia feel alone, cut off from her friends and allies. For example, she could be in a situation where she is the only one who can face a certain threat, and no one really understands what she's going through. This can lead to her feeling like she has to handle everything by herself in a very dark and difficult world. It also gives the writer a chance to explore how she copes with this extreme loneliness.

Through their relationship, they both discover new aspects of themselves. For instance, Rukia might discover a stronger side of herself because of Renji's support, and Renji might discover his capacity for deep love.

Growth is also a big theme. As they interact more, both rukia and tatsuki grow as individuals. For example, they might become more confident or learn new skills. And sometimes, there's a theme of sacrifice, where one is willing to sacrifice for the other in the story.
