Perhaps in the fanfiction, there's a parallel universe where Sakura and Syaoran are enemies. They have to figure out what has gone wrong and how to set things right.

One idea could be a new student arrives at Waterlooo Road with a big secret. Maybe they are a talented artist but are too shy to show it at first. As they make friends, they gradually open up and use their art to transform the school environment.
Perhaps they are both involved in a time - travel adventure. Sakura and Anko find themselves in a different era in the ninja world.

Well, a plot could be that Sakura is a healer in a war - torn land and Indra is a powerful warrior. Indra gets seriously injured and Sakura has to use her skills to heal him.

This could lead to a change in Indra's perspective on things and a budding relationship between them. It could also create conflict as some in Indra's clan might not approve of his new - found friendship with Sakura.
A really interesting plot could be a time - travel fanfiction. Suppose Sakura somehow travels back in time and meets a younger Kisame. She tries to change his path, knowing the future he will have.

One idea could be Sakura using her intelligence to outwit the prison guards and help other inmates. For example, she might find a loophole in the prison rules that benefits the inmates in some way.
Sakura could be homeless because she ran away from an oppressive situation at home. While homeless, she forms a bond with a group of other homeless people who teach her survival skills.
