In fanfiction where Hermione is Bella's sister, what kind of adventures could they have together?

Well, they could embark on an adventure that involves international intrigue. Maybe a valuable artifact has been stolen and is being smuggled across different countries. Sherlock and Hermione would use their combined skills to track it down. Sherlock would use his detective skills to follow the clues on the ground, while Hermione would use her knowledge of different languages and cultures (gleaned from her studies) to help them navigate through different countries and understand the motives behind the theft.

One adventure could be to stop a group of villains who are stealing magical artifacts to power up high - tech weapons. Hermione would use her magical skills to track down the artifacts and Tony would use his engineering skills to disable the weapons. Along the way, they'd learn from each other and develop a closer bond as siblings.

They could have adventures related to magical creatures. Since Cedric is a Hufflepuff, he has an affinity for them, and Hermione's thirst for knowledge would make them a great team. Maybe they go on a quest to find a rare and endangered magical creature and try to protect it from poachers. They would use their combined skills, Cedric's charm and physical abilities and Hermione's magic and intelligence.

If Hermione was Oliver's sister in fanfiction, they could have all sorts of adventures. For one, they could team up to investigate strange happenings around Hogwarts that seem to be affecting the Quidditch games. Since Hermione is smart and Oliver is observant in the Quidditch field, they'd make a great team. They might also go on a quest to retrieve a lost Quidditch trophy that has some sort of magical power. And perhaps they'd get involved in a mystery involving a cursed Quidditch broom that is causing trouble for the players. Their combined skills would surely help them solve these problems.

Maybe they'd have to save their family from a common enemy. Since they are siblings in this fanfiction, their family could be in danger from a being that wants to use their combined powers. This would lead them on an adventure through both the wizarding world and the world of Greek gods, having to use Hermione's knowledge of spells and Percy's ability to navigate the world of the gods to keep their family safe.

They could go on an adventure to find a lost family heirloom. This heirloom might be a powerful magical object that was lost during the First Wizarding War. Sirius, with his knowledge of the era, and Hermione, with her research skills, would make a great team to track it down.

They could go on a quest to find a lost family heirloom. This heirloom might have special powers that could help in the fight against the dark forces. Along the way, they'd face various challenges like magical creatures and dark wizards.

They could go on a journey to discover more about their family's past. Maybe there are some hidden secrets in their family tree that are linked to both the world of Greek mythology and the supernatural world of Twilight. Or they could team up to fight against a common enemy. For example, a new kind of supernatural being that is a threat to both vampires and demigods.

Well, they might embark on a journey to find a lost magical artifact. Since Emmett is physically powerful and Bella is quite intelligent, they could combine their skills. Emmett could handle any physical threats or obstacles, like fighting off wild animals, while Bella uses her wits to decipher clues leading to the artifact.

They could go on adventures to discover lost magical artifacts. For instance, they might search for an ancient wand rumored to have extraordinary powers. Along the way, they would face various obstacles like traps set by long - dead wizards and magical creatures guarding the artifact.
