Well, in some fanfictions like 'The Forgotten Sister of Zeref', it could be about how she was overlooked in the main Fairy Tail narrative but has a significant role to play. Maybe she has a connection to some ancient magic that could either save or destroy the world. 'Sisterly Bonds in Fairy Tail' might be another good one, which delves deep into the emotional bond between Zeref and his sister, and how it affects the events in the Fairy Tail universe. There are also those fanfictions that might give her a completely different personality from what we expect, like in 'Zeref's Rebellious Sister', where she goes against his ways and tries to create a new path for herself and those around her.
One popular fanfiction could be 'The Sister's Redemption'. It might explore the relationship between Zeref and his sister in a unique way, perhaps showing how she tries to save him from his dark path. Another could be 'Sister of the Dark Mage', which may focus on her own powers and how she uses them in the context of the Fairy Tail world. And there's also 'Zeref's Sister: A Hidden Power', where her powers are a mystery that gradually unfolds throughout the story.
There are various fanfictions out there. For instance, 'Zeref's Sister: A New Hope' could be a story where she emerges as a symbol of hope in the dark world of Fairy Tail that Zeref has partly created. It might show her as a beacon of light, trying to bring back the good in her brother. 'The Enigmatic Sister of Zeref' might be centered around her being an enigma, with her actions and motives not being clear at first. As the story progresses, we learn more about her and her place in the Fairy Tail world. And 'Sister's Love in the Time of Darkness' could explore how her love for Zeref, despite his actions, is unwavering and how she uses that love to try and change the course of events.
