Fanfiction about Naruto, Sasuke and Sakura as siblings: What are some interesting plot ideas?

A possible plot in this fanfiction could be that Naruto and Sakura, as siblings, inherit a special jutsu from their ancestors. They have to figure out how to master it together. In the process, they get into all sorts of adventures. They might have to deal with a corrupt ninja in their village who wants to steal their inheritance. Their relationship as siblings would be a source of strength and support, as they rely on each other's unique abilities. For example, Naruto's determination and Sakura's intelligence would complement each other in solving problems.

How about a story where an unknown enemy creates clones of them? Naruto, Sasuke, and Sakura have to not only fight these clones but also figure out who the enemy is and why they are being targeted. Along the way, they might discover new powers within themselves and also learn more about their relationships with each other.

In a fanfiction, there could be a story where a mysterious enemy targets Sasuke, Naruto and Sakura specifically because of their unique bond. The three of them then have to go into hiding and figure out who the enemy is and what they want. Along the way, they rely on each other's strengths and grow even closer as friends.

Perhaps a fanfiction where Sasuke loses his memory and Sakura has to help him regain it. She takes him back to all the places that are important to their past, like their old training grounds. As she tries to jog his memory, they end up reliving old memories and emotions, and this could lead to a rekindling of their relationship in a very emotional way.

A plot could involve time travel. Naruto and Hinata find themselves sent back in time, and they have to find a way to get back to their own time. Along the way, they meet a younger Sasuke and Sakura. This gives Naruto a chance to try and prevent some of the bad things that happened in Sasuke's past, and Hinata can bond with a younger Sakura, sharing her own experiences of growing up shy and how she overcame it.

One plot idea could be that in an alternate universe, Sasuke and Sakura have been in a relationship for a while. Naruto, being their close friend, witnesses their first real kiss during a moment of celebration after a big victory in the village. This kiss could symbolize the stability and love they've found in each other, and Naruto's reaction could be a mix of happiness for his friends and a tinge of his own loneliness.

One plot idea could be that they discover they are siblings through some long - lost family secret. Then they have to navigate the new relationship while also dealing with the threats to their village. Another could be a story where they go on a journey together to find out more about their family's past.

Maybe a plot where Sasuke and Sakura go on a mission together, and Naruto's family has to step in to help when things go wrong. For example, Sasuke and Sakura are sent to investigate a strange occurrence on the outskirts of the village. But they get trapped, and Naruto's son, using his unique skills learned from his father, manages to find and rescue them, strengthening the ties between the families even more.

One plot idea could be Sai trying to understand the deep bond between Naruto, Sakura and Sasuke. He might initially struggle as he has his own unique upbringing. For example, he could be assigned a mission with the three of them and slowly learn about their history, like Naruto's determination to bring Sasuke back and Sakura's unrequited love for Sasuke in the beginning. This could lead to Sai having a new perspective on friendship and loyalty.

Perhaps in this fanfiction, they are the only ones who can stop an ancient evil that has been awakened. They are inseparable in the sense that they are constantly protecting each other. Naruto might use his Rasengan to create openings, Sasuke with his Sharingan to analyze the enemy's moves, and Sakura to heal any injuries they sustain immediately, making them an unbeatable trio.
