Well, often you'll find the theme of coming - of - age. They are in the academy, which is a stage of their lives where they are starting to understand the world of ninjas and their own places in it. Additionally, there can be themes related to family. For instance, how their family backgrounds influence their behavior and goals at the academy. And of course, the theme of loyalty, whether it's loyalty to their classmates, their sensei, or the village as a whole.
Growth as ninjas is also a popular theme. Both Naruto and Ino have their own goals and dreams in the original series. Fanfictions often show how they help each other achieve new levels of power and skill. For example, Naruto might inspire Ino to be more confident in her jutsu, and Ino could teach Naruto some mental techniques to enhance his focus.
Friendship is a very common theme. Since Naruto, Ino, and Sakura are all from the same village and have grown up together in a way, many fanfictions explore the deepening or changing nature of their friendship. For example, they might face a difficult situation that tests their loyalty to each other.
A significant theme is the legacy of the Yamanaka clan. Inoichi represents the older generation of the clan, and Ino is the new hope. Fanfictions often deal with how Ino will carry on the clan's traditions and make it even greater. This can involve her learning the clan's jutsu, like the Mind Transfer Technique, and using it in new and creative ways to uphold the Yamanaka name in the ninja world.
