What are some interesting plot ideas for 'a deadly education fanfiction'?

One idea could be the seven deadly weapons being tied to ancient ninja clans in the Naruto world. For example, a weapon might be hidden within a clan's secret temple and its discovery could start a race among different ninja groups. Another could be that the weapons are cursed and whoever wields them starts to be influenced by the deadly sin associated with each weapon, like the sword of wrath causing the wielder to have uncontrollable anger.

One idea could be an OC who is a hybrid of two of the deadly sins, like pride and envy. This OC could struggle with the internal conflict of these two powerful emotions. For example, being envious of the power of other characters while also being too proud to admit it or ask for help. Another plot could be an OC who is on a quest to redeem the Seven Deadly Sins themselves, believing that they can be reformed. This would involve the OC facing many challenges and having to understand the true nature of each sin.

One idea could be exploring the backstories of the minor characters more in - depth. For example, the life of a sidekick before they joined the school. Another could be a 'what - if' scenario where the main character makes a different choice at a crucial moment, like choosing not to go on a certain mission. A third idea is to create a fanfiction that focuses on the relationships between the teachers and how they interact outside of the classroom.

One interesting plot idea could be that in the Minecraft world, the characters from Seven Deadly Sins are transported there. For example, Meliodas could be on a quest to find a special diamond that has the power to restore his lost strength. And the Minecraft mobs could be influenced by the sins. The zombies could be more aggressive due to wrath, and the pigs could be gluttonous and overeat the crops in the game.

A plot could involve Kirito being cursed by a powerful enemy related to the Seven Deadly Sins' lore. The curse affects his ability to log out or communicate with his own world. In order to break the curse, he has to help the Seven Deadly Sins complete a series of dangerous quests. Along the way, he forms deep bonds with each of the sins and learns about their pasts and how they are dealing with their own 'sins'.

A plot could be that Escanor and Merlin are tasked with training a new generation of knights. They have different teaching styles, with Escanor focusing on physical and mental fortitude, and Merlin on magical abilities. This leads to some humorous and also some tense moments as they try to work together.

Maybe a plot where Merlin discovers a prophecy that only Escanor can fulfill, but it requires him to sacrifice something dear to him. They embark on a journey to find a way around the sacrifice while also falling in love along the way. There could be many challenges like facing ancient guardians and deciphering cryptic riddles.

One plot idea could be Percy having to face off against manifestations of the 7 deadly sins within the Camp Half - Blood. For example, a character being influenced by pride and causing chaos among the demigods. Another could be Percy being tempted by the sin of envy when he sees another demigod getting more recognition. And perhaps a plot where sloth has spread among the campers, making them lazy in their training and Percy has to find a way to snap them out of it.

There are fanfictions that focus on the role of extracurricular activities in magical education. For instance, a Quidditch - based educational program where students learn about teamwork, strategy, and leadership through the sport. Additionally, some stories might explore how different houses could have specialized educational tracks. For example, Gryffindors could have a track focused on courage - related magic, like facing the most dangerous magical creatures for research purposes.

It's a story set in a magical school where the environment is extremely dangerous. The main character has to struggle to survive while also dealing with her own powers and the complex social dynamics among students.
