Along the way, she has to face her own identity crisis and deal with the political implications of her new - found family relation.
Another plotline could be that she was cursed as a child and lost her memories. Years later, she starts to regain her memories and realizes she is a Malfoy.

It could involve adventures in finding a way to break the curse completely.

One possible plotline could be that Naruto's family is in a difficult situation and they believe they can only support his sister. So, Naruto is left on his own.

Perhaps she has a special connection to an ancient and powerful ninja art. This could lead to her being targeted by some villains who want to use her for their own gain.

One possible plotline could be that Naruto's sister is overly protective of him. She might get jealous when Naruto spends time with his friends, especially female friends.

A plot could involve Fleur's sister having a special ability that she has to keep hidden. Harry discovers this secret accidentally.

Or, she could be a target of the Death Eaters because of her family's connection to the Beauxbatons Academy. Harry then has to protect her, leading to a series of action - packed scenes around Hogwarts and the wizarding world.
One possible plotline could be that the long lost sister was separated from Harry due to a powerful dark wizard's curse.

One possible plotline could be that Lemon has some unique ninja abilities that Naruto discovers, and they train together to become stronger. Maybe she has a special chakra nature that Naruto has never seen before, and they figure out how to use it in combat.

This would bring a whole new set of challenges as she has to balance her love for this person and her loyalty to her family. There could be a lot of drama as she tries to keep her relationship a secret or convince her family to accept it.
