One possible plot could be a comical take. Maybe in an alternate magical world, a chastity belt is a magical item with a powerful spell on it. Hermione accidentally comes across it during one of her research adventures in the library. She and Harry then have to figure out how to remove it without causing any harm or breaking any magical laws. It could be filled with humorous attempts and near - misses as they try different spells and potions.
Well, it could be a story about a new form of magical protection. The chastity belt could be reimagined as a symbol of protection against dark magic influences on one's purity of magic. Hermione, being the brilliant witch she is, might study it to understand its properties. Harry could be involved as her helper and friend, and together they could figure out how to use this 'new' chastity belt concept to protect Hogwarts from a new dark magic threat.
One great 'Harry Potter Hermione Granger' fanfic is 'Harmony's Embrace'. It beautifully portrays their relationship development in a post - Hogwarts world. The story is filled with magical adventures and the deepening bond between Harry and Hermione.
Some fanfics use unique items like a collar to explore different aspects of the characters. In a story with Harry Potter and Hermione Granger, the collar could represent a form of restraint, either self - imposed or magically forced. This could lead to a plot where they have to break free from it, both literally and metaphorically, as they face challenges in the wizarding world.
A fanfic could also center around a mystery related to a collar found in Hogwarts that Hermione and Harry investigate together. They suspect it might be related to a secret society or an old magic. As they dig deeper, they discover that the collar has the power to unlock hidden passages in the castle, and they must use it to stop a dark force from awakening.
One great fanfic that involves Harry Potter, Hermione Granger and has something to do with a harness could be 'The Enchanted Harness Adventure'. In this fanfic, Hermione discovers an ancient magical harness in the Forbidden Forest. It has the power to enhance the wearer's magical abilities. Harry and Hermione then go on a journey to figure out the true origin and purpose of the harness. It's full of mystery and adventure.
One idea could be that after a major battle, Hermione realizes that she and Harry have grown in different directions. She decides to break their friendship in order to pursue her own path of magical research. This could lead to a story where Harry initially feels betrayed but then comes to understand Hermione's decision as he too embarks on his own journey of self - discovery.
Another one is 'The Time - Twisted Trio'. In this fanfic, they accidentally travel back in time and have to deal with the past versions of themselves and their friends. It's really interesting to see how they handle the situation while still maintaining their core characters.
One possible fanfic idea could be that Hermione becomes a maid to help out a poor wizarding family. As a maid, she would bring her logical thinking and magic skills to make their lives better. For example, she could use magic to clean in a more efficient way and also tutor the children of the family in magic, all while facing the typical class differences in the wizarding world.
Another theme is power and knowledge. Since Hermione is known for her intelligence, fanfics often focus on how she and Harry use their combined knowledge and power to overcome challenges. For example, in some fanfics, they discover new spells or magical artifacts together. It also often shows how their different strengths complement each other in difficult situations.
