The Aldini brothers, especially Isami, could be good characters to include. They could offer a different cultural perspective on cooking, and Isami's support of his brother Takumi could add some family - like dynamics to the fanfiction. Plus, their unique cooking skills could contribute to the overall story.
One idea could be that Takumi and Megumi team up for a special cooking competition against a team of international chefs. They combine their unique skills, with Takumi's Italian - inspired techniques and Megumi's Japanese traditional cooking knowledge, to create a fusion menu that wows the judges.
One common theme is the discovery of love. Takumi and Megumi often start as friends or acquaintances and gradually realize they have deeper feelings for each other. Another theme could be personal growth. Through their relationship, they both learn more about themselves and become better individuals.
One popular takumi x megumi fanfiction might be 'A Chance Encounter'. In it, Takumi and Megumi meet in an unexpected situation, like at a local fair. Their personalities start to mesh as they share a common interest in art. The story unfolds with them gradually realizing their feelings for each other. It's a sweet and simple take on their relationship.
I think Hinata could be a great addition. He could be the comical sidekick who always gets into funny situations and in the process, either helps or hinders Usui and Ayuzawa's relationship. Another good character could be Ayuzawa's mother. Her presence could add some family drama, like she might not initially approve of Usui for her daughter.
Their relationship could develop through shared cooking experiences. For example, if they are constantly cooking together for the school's events, they start to understand each other's cooking philosophies better, which in turn deepens their connection.
A really interesting plot could be set in a post - Shokugeki no Soma world. Takumi and Megumi open their own restaurant together. But they face challenges like a new rival restaurant in town. They have to use their combined skills and the bond they've developed over the years to not only survive but thrive in the competitive food business. They could also have to deal with personal issues like Takumi's family's expectations and Megumi's insecurities, all while creating amazing food.
There are also fanfictions that focus on cultural exploration through food. Since Soma has his own unique style influenced by his father and his upbringing, and Megumi has her traditional Japanese culinary background, writers might use this as a theme. They could show how the two characters learn from each other's cultures and incorporate different elements into their cooking, which in turn affects their relationship.
One popular storyline could be Soma and Megumi collaborating on a special menu for an important event at the school. They combine their unique cooking styles and ingredients, facing various challenges along the way, like sourcing rare ingredients or dealing with a strict time limit.
There might be a fanfiction where Megumi has a cooking competition against Soma. In this story, Megumi overcomes her self - doubt and really shows off her skills. Soma, on the other hand, is also pushed to his limits, and in the end, they both gain a new respect for each other's cooking abilities.
The enchanted objects in the castle like Lumière and Cogsworth would be great. They add humor and charm to the story. Also, Gaston could be included in a different way, like he has a change of heart and tries to help them. And Belle's father could also be a key character, perhaps he discovers something important about the curse.
