There's a fanfic where James adopts Hermione after she has a falling out with her own family in the muggle world. This story focuses on how Hermione discovers a new kind of family in the wizarding community led by James. It shows her growth and the bond she forms with James and his friends. There are many sweet moments like when James teaches Hermione some old family magic spells.
There's also 'Remus's Little Hermione'. This story delves deep into how Hermione's intelligence and Remus's wisdom blend together. It details their daily life, from Hermione helping Remus with his research to Remus teaching Hermione some advanced magic. Their relationship evolves beautifully in this fic.
One great 'loki adopts hermione fanfiction' is 'A Godly Adoption' where Loki takes Hermione under his wing in a world filled with magic and Norse mythology crossovers. The story is full of interesting character interactions.
There's 'Sirius's Little Witch'. This fanfiction focuses on how Hermione's intelligence and Sirius's rebellious nature work together. Sirius provides Hermione with a different perspective on magic, one that's not always taught in the books at Hogwarts. The story is full of little adventures they go on together around the wizarding world.
It's interesting because it combines two beloved characters from different generations. James, from the older generation, and Hermione, from Harry's generation. It creates a unique dynamic as James can pass on his knowledge and wisdom to Hermione.
I also recommend 'Adopted by Harry'. This fanfiction focuses on the impact of Hermione's new family situation on her Hogwarts life. It's quite heartwarming to see how Harry tries to give Hermione the family she never had and how she blossoms in this new environment.
Yes, there are many. Some fanfiction platforms like FanFiction.net and Archive of Our Own have a plethora of such stories. You can search for them using the tags 'James Potter' and 'Hermione Granger'. The quality varies, but there are some real gems that explore different aspects of their relationship, like them teaming up on a secret mission in Hogwarts and how their different personalities complement each other during the adventure.
There's also 'Adopted by the Sannin'. Here, Naruto is adopted by one of the Sannin. Each chapter explores different aspects of his growth under their tutelage, and how his relationship with the other Sannin and the village also evolves. It's really interesting to see how Naruto's character is shaped in this alternate scenario.
One possible plotline could be Hermione using her intelligence to create a stable and loving home environment for Harry. Maybe she helps him deal with his PTSD from his past traumas. Another could be them facing magical threats together as a family, with Hermione teaching Harry new spells and ways to protect himself.
In some fanfictions, the plotline might involve a time - turner related incident. Maybe Hermione gets into some sort of trouble with time - traveling that only McGonagall can help her with. As a result, McGonagall adopts her to keep a closer eye on her and make sure she doesn't get into more dangerous situations. This could lead to some really interesting scenes where McGonagall teaches Hermione more advanced magic and Hermione uses her knowledge in new and creative ways under McGonagall's guidance.
One interesting plotline could be Hermione's struggle to adjust to living with Snape. She's used to the warm and inclusive environment of Gryffindor, and Snape's dark and brooding personality makes it a big change for her. Another could be Snape seeing Hermione's potential not just as a student but as a daughter figure, and he starts to teach her advanced magic privately, which in turn helps Hermione to solve some of the school's mysteries.
