In the fanfiction, it could be that Hermione is magically transported to a realm where Lucifer exists. There, she has to use her wits and magic to survive. She might find that Lucifer is not exactly as the Muggle stories portray him. He could be more complex, and Hermione starts to have philosophical discussions with him about power, knowledge, and free will. This experience changes her perspective on magic and life in general, and when she returns to the wizarding world, she tries to implement some of the new ideas she gained from her encounter with Lucifer.
One possible plotline could be that Hermione, being the intelligent and curious witch she is, stumbles upon the legend of Lucifer in the Muggle world. She becomes intrigued by the concept of such a powerful and complex figure. Maybe she starts researching more about Lucifer's nature and motives, and this new knowledge somehow influences her magic or her relationships at Hogwarts. For example, she might start to question the nature of good and evil in the wizarding world in a new light, similar to how Lucifer is often a symbol of rebellion against the status quo in his own lore.
One plotline might be that the Naruto universe and Lucifer's world collide. Naruto teams up with some of Lucifer's allies (or enemies) to save both worlds from a common threat. For example, a powerful demon from Lucifer's world is trying to invade the ninja world, and Naruto, with his new - found knowledge of Lucifer's powers and the underworld, has to lead the charge to stop it.
One possible plotline could be that Hermione discovers a passion for a particular type of dance, like ballet. She might start taking secret lessons and face challenges from her friends who don't understand her newfound love. As she progresses in her dancing skills, she could enter a local competition and use her intelligence to choreograph a unique routine, impressing everyone and showing that she can excel in something other than academics.
One possible plotline could be that Hermione discovers a way to time - travel and goes back to Snape's childhood. She decides to raise him in a more positive environment to change his future. Maybe she teaches him about love and friendship from a young age, which alters his personality and his relationship with others at Hogwarts later on.
Well, perhaps in the fanfiction, Sirius would take Hermione on adventures around the wizarding world. Since he was part of the Marauders, he'd know all kinds of hidden places. They could visit ancient magical sites, and along the way, Sirius would share stories about her parents if he knew them. This would not only give Hermione a broader knowledge of the wizarding world but also a sense of connection to her past. Also, he might train her to be a better dueler, preparing her for any threats that come her way in the future.
Perhaps Hermione meets the Marauders when they are in the middle of planning one of their big pranks. They might be suspicious of her at first, thinking she's a spy or something. But then, as they get to know her, they realize she's actually really brilliant. They could end up working together on a new kind of adventure that combines Hermione's intelligence and the Marauders' mischievousness, like solving a mystery in Hogwarts that has been long forgotten.
One possible plotline could be Harry struggling to come to terms with his new identity as the Son of Lucifer. He might face internal conflict, wondering if he's doomed to be evil like his supposed father. Another could be the wizarding world's reaction to his revelation. Some might fear him, while others might try to use his power for their own gain.
One possible plotline could be that they got engaged during a dangerous adventure. Maybe they were trapped somewhere and made a pact to get engaged if they survived. And then they keep it a secret because they know their friends and families might not approve. For example, Ron might be really shocked and angry at first if he found out.
One possible plotline could be Severus acting as a mentor to Hermione as she grows. He might teach her advanced potions in a more private setting, sharing his deep knowledge of the subject. This could lead to Hermione developing a new respect for Severus, different from the initial wariness in the original story.
A plot could involve a magical accident that causes Hermione to see Dolohov in a different light. Maybe a spell backfires and she starts seeing his memories, understanding his past traumas that led him to become a Death Eater. This new understanding makes her develop feelings for him. But she has to deal with the fact that he's still on the wrong side in the eyes of the wizarding world. She might then try to subtly nudge him towards the good side while hiding her crush from everyone else.
It could be that Hermione has a secret life as a part - time Animagus. She has been able to transform into an animal without anyone in Hogwarts knowing. She uses this ability to explore places she couldn't reach as a human, or to spy on the Death Eaters or other threats to the wizarding world. And she keeps it a secret because Animagus without permission can get into a lot of trouble in the wizarding society.
