Love and friendship can also be themes. The sister might form deep friendships with other characters in the Naruto universe. And in some cases, there could be a romantic sub - plot for her. This could be with a character from her own clan or someone outside like a ninja from another village. These themes add different layers to the fanfiction and make it more engaging for readers.
Perhaps the fanfiction could focus on the little sister's own journey of self - discovery. Growing up in the shadow of her two powerful brothers, she might strive to find her own identity and power.

To develop the little sister's character, you could focus on her growth over time. Maybe she starts off as a shy girl but through various experiences, like joining a school club or participating in a community event, she becomes more confident. Her reactions to challenges are important too. If she faces a bully, does she cower or does she find a way to stand up for herself? Additionally, her dreams and aspirations can shape her character. If she wants to be a scientist, show how she pursues that interest, even with the twins' sometimes over - the - top protectiveness.
In some fanfictions, she could be a victim of the faction system in a way that Eric doesn't fully understand. This could create a rift between them as she struggles with her own identity and the expectations placed on her because of her brother's position. It could also be a story of her finding her own voice and fighting for what she believes in despite the obstacles.
