First, understand the lore of the Seven Deadly Sins. Know the characteristics of each sin and how they function in the original story. This knowledge will help you create an OC that fits well into the universe. For example, if your OC is related to envy, study how envy is portrayed in the original series.
One reason is the unique take on the Seven Deadly Sins concept. An original character (OC) in this fanfiction can bring a fresh perspective. For example, if the OC has a complex backstory related to one of the sins, like pride. Maybe the OC was once a noble who lost everything due to excessive pride but is now on a journey of redemption within the world of the Seven Deadly Sins. This kind of character development can be really engaging.
To write an intriguing plot for a Ban x OC fanfiction, start with a strong concept. Maybe the OC has a special power that Ban needs for a particular mission. This immediately creates a connection between them.
One common theme is redemption. Often the oc has to deal with their own flaws or sins and find a way to redeem themselves in the world of the seven deadly sins.

The Seven Deadly Sins of the V Family isn't a common genre of novels, so it's hard for me to recommend any related novels. However, if you have any other categories or topics that you need, please let me know. I'll do my best to help you.
First, you need to study the two universes well. Know the powers, the characters, and the settings. For example, in My Hero Academia, quirks are unique to each character, while in Seven Deadly Sins, there are different types of magic. Then, think of an interesting plot. Maybe a crossover where the students of U.A. High visit the world of the Seven Deadly Sins.
A great way to create a memorable OC for Seven Deadly Sins fanfiction is to mix different elements from the existing characters and the world. Take some of the personality traits of the main characters and combine them in a new way. For instance, an OC could have the loyalty of Ban and the intelligence of Merlin. In terms of appearance, draw inspiration from the medieval - like setting of the series. Give them a weapon or an ability that is not common in the series. For example, an OC that can control shadows in a way that is different from any other character. Their motivation should also be clear, whether it's revenge, love, or something else.
The diverse and complex characters. They have depth and flaws, making their journeys interesting.
Research the original story well. Understand the world - building, the powers of the characters, and their relationships. Then, you can create new scenarios that are suitable for all audiences. For instance, you could write about how the characters team up to solve a mystery in their world that is related to the sins concept, but without any adult elements. You can also add new characters that bring out different aspects of the sins in a more family - friendly way. Another aspect is to use humor. For example, make a character's struggle with gluttony be more of a comical thing where they overeat something silly like too many cupcakes at a party instead of something more inappropriate.
First, establish a common threat. For example, an ancient evil that can only be defeated by combining the unique powers of Naruto, Merlin, and the Seven Deadly Sins. This will force them to work together.
