Well, in this kind of fanfiction, an ending could be that Sakura's death is final and the world she saved slowly forgets about her. This would be a really sad and bittersweet ending. However, another ending might be that her sacrifice actually transforms her into a kind of spirit or guardian angel of the world. She still exists in a different form and is able to watch over everyone she saved. Also, there could be an ending where her death sparks a revolution in the magical world, changing the rules and how things are done to prevent such a sacrifice from ever being necessary again.
One possible ending could be that her sacrifice is successful and everyone she saved lives in a world filled with her memory. They might create monuments or hold annual events in her honor. Another ending could be that her death actually breaks the balance of magic in the world, leading to unforeseen consequences despite her noble intention. Or perhaps her friends find a way to bring her back in the end, using their own combined powers and the power of their love and friendship for her.
In the fanfiction where Cardcaptor Sakura dies to save everyone, a possible ending is that the characters she saved are left with a deep sense of guilt. They constantly question if they could have done something to prevent her death. Another ending could be that her death unites different magical factions that were previously at odds. They come together to create a new, more peaceful world in her name. And yet another ending could be that her sacrifice leads to a new prophecy about a future hero who will be like Sakura but will be able to achieve the same goal without sacrificing their life.
One possibility could be that Akio gets into a situation where he is in great danger, like being trapped in a magical realm full of powerful dark forces. Cardcaptor Sakura, being the brave and selfless character she is, sacrifices herself to free Akio. Maybe she uses all her Clow Card powers at once, which drains her life force but manages to break the spell binding Akio.
On the other hand, many fans would also admire Sakura's selfless act. They would see it as a testament to her character and the values she represents. It could start interesting discussions among fans about sacrifice and heroism in the context of the Cardcaptor Sakura universe. They might even create fanart or more fanfiction inspired by this noble act of Sakura's.
In such a fanfiction, the plot would likely be extremely tragic. Cardcaptor Sakura, being a selfless character, would sacrifice herself for the greater good. Her character development could be seen as reaching its peak in this ultimate act of heroism. It would show her growth from a somewhat naive girl to a true hero. All the relationships she has built throughout the story, like with Syaoran and Tomoyo, would be deeply affected. Her friends would be devastated, and it would also be a test of their own growth as they deal with the loss.
A tragic ending could be that Harry's death leads to the fall of the good side in the wizarding war. His friends, demoralized by his loss, are unable to fight back effectively against the dark forces.
A fanfiction could focus on Sakura and Syaoran's daily life after the main events of Cardcaptor Sakura. Maybe they are training new cardcaptors. They could be facing challenges like how to teach the newbies about the importance of the cards and the right way to use their magic, all while their relationship continues to develop in this new phase of their lives.

She then devotes her life to making the village a better place, just as Naruto would have wanted. Another ending could be that the whole village unites even more tightly after Naruto's death, with Hinata at the forefront of this unity, as she was the last person Naruto protected.
One possible plot could be that Naruto sacrifices himself to protect Sakura from a powerful enemy. Maybe he uses a forbidden jutsu that drains his life force but saves her from certain death. Sakura would be left in shock and grief, and this could lead to her seeking revenge against the enemy or trying to find a way to bring Naruto back, perhaps through some ancient ninja magic.
One possible plotline could be during a powerful enemy attack on the village. Sakura might sacrifice herself to save Naruto and the rest of the village.

One possible plotline could be that Percy's sacrifice leads to a new era of peace in the fictional world.
