What are some interesting plot ideas for Trinity Seven fanfiction?

Perhaps a crossover where the Trinity Seven characters enter a post - apocalyptic world. Their magic would be both a great asset and a source of danger as other survivors might see them as threats or saviors. They'd have to figure out how to survive and maybe even find a way to restore the world using their powers.

A plot idea could involve a character from Highschool DxD getting lost in the world of Trinity Seven and having to adapt to their magic system. They could learn new spells and make new friends along the way, all while trying to find a way back home. It would be a great opportunity for character development and exploring the differences between the two universes.

Another interesting concept is an OC who is from a completely different dimension but gets drawn into the Trinity Seven world. This OC could have a different set of values and magic rules from their own dimension, which would create a lot of interesting interactions and conflicts with the existing characters.

Well, a plot could revolve around Arata and Lilith being sent back in time to a crucial moment in the history of their magical world. They have to make sure that the events unfold correctly without changing the future too much. This would put a strain on their relationship as they might have different ideas on how to handle things. Another idea is that they find a mysterious prophecy that involves the two of them and they have to figure out what it means. As they search for answers, they encounter old enemies and new allies, all while their relationship evolves.

Another idea is that there is a mysterious illness spreading among the Trinity Seven members. Akio is one of the first to be affected, and Arata is determined to find a cure. He goes on a journey, visiting different places and asking for help from various magical beings. This fanfiction could explore Arata's determination and his growth as he faces numerous obstacles in his quest to save Akio. It could also show the bond between them as Arata refuses to give up on his friend.

One plot idea could be that the male OC discovers a hidden power within the Trinity Seven world that no one else knew about. This could lead to a race among different factions to either control or destroy this power. Another idea is that the OC has a connection to an ancient prophecy that involves the Trinity Seven characters. As he tries to figure out his role in the prophecy, he forms closer bonds with the group.

One interesting Trinity Seven lemon fanfiction could be about the characters' unique magical adventures within a romantic context. For example, a story where the main character uses their magic in creative ways to impress their love interest among the Trinity Seven.

One idea could be that Naruto characters are transported to the Trinity Blood universe. Naruto, with his strong will and powerful chakra, might be seen as a threat or a potential ally in the complex political and religious landscape of Trinity Blood. For example, his shadow clone jutsu could be mistaken for some form of dark magic in that world.

One idea could be that Terumi and Trinity are forced to team up against a common enemy. Maybe a new, powerful force emerges in the BlazBlue universe that threatens both of their interests. They start off distrusting each other but gradually learn to work together and in the process, develop an unexpected bond.

A great crossover aspect could be the character interactions. Imagine Harry Potter meeting the characters from Trinity Seven. They would likely have very different personalities and ways of approaching magic. Harry's more traditional Hogwarts education might contrast with the more modern and complex magic in Trinity Seven. Their combined efforts could lead to some really exciting adventures and new ways of using magic.
