What are some interesting crossovers in 'owari no seraph x final fantasy xv fanfiction'?

One theme that could be explored is the struggle for survival. In 'owari no seraph', the humans are constantly fighting for their lives against the vampires. In 'Final Fantasy XV', the characters also face many threats. In the fanfiction, this could be combined, like the characters from both worlds having to fight a common, even more powerful enemy that tests their will to survive.

One interesting crossover could be the use of magic spells from 'Harry Potter' in the world of 'Final Fantasy XV'. For example, a character from 'Final Fantasy XV' might learn the Patronus Charm to fend off daemons. Another could be the appearance of Hogwarts - like buildings in the 'Final Fantasy XV' landscape. Maybe Noctis and his friends could attend a magical school similar to Hogwarts.

Some 'owari no seraph fanfiction' stories might be about alternate endings. What if the main characters made different choices? For instance, if Yuichiro decided to fully embrace his vampire side instead of fighting against it, how would that change the entire story? Writers can take this concept and create really engaging and thought - provoking fanfictions.

One possible analysis could be that it allows for a more personalized take on the 'Owari no Seraph' universe. OC (original character) fanfictions often bring in new storylines and character dynamics. It might explore relationships between the existing characters in the series and the newly created OC in unique ways, such as a romantic relationship or a friendship that changes the course of the story.

One idea could be exploring the backstories of the main characters in more depth. For example, Noctis' training as a prince and his relationship with his father before the events of the game. Another could be a fanfiction set in an alternate universe where the Astrals have different roles or relationships with the humans. Maybe a story where Noctis and his friends have to face a new, unexpected threat that wasn't in the original game.

In some Naruto x Final Fantasy fanfiction, the summons in Naruto could be related to Final Fantasy summons. Like the toads in Naruto could have a connection to a similar creature from Final Fantasy. This would create unique interactions between the two universes.

Some cool crossovers might include Naruto's summoning jutsu being used in the world of Final Fantasy X - 2. He could summon giant toads or snakes, which would be a strange sight in Spira. The Al Bhed language from Final Fantasy X - 2 could be something Naruto characters have to learn. And perhaps the Farplane in Final Fantasy X - 2 could have a connection to the afterlife in the Naruto universe. This could lead to some really deep and emotional storylines where characters from both worlds interact with the concept of death and the afterlife.

A crossover with 'Fullmetal Alchemist' would also be cool. Maybe the alchemical powers in that world could interact with the vampire and demon powers in 'owari no seraph'. The characters could be on a quest to find a way to either cure the vampires or use alchemy to stop the apocalypse that's happening in 'owari no seraph'.

A possible plot is that the Death Eaters from Harry Potter somehow make a pact with the vampires in Owari no Seraph. This forces the good guys from both universes, like Harry and Yuu, to join forces. They might have to figure out how to break the pact and defeat their common enemies. It could also involve some interesting character dynamics, like Draco Malfoy being forced to work with Mikaela, a vampire from Owari no Seraph, and slowly changing his views.

One idea could be a 'what if' scenario where the main characters have different abilities from the start. For example, Yuichiro could have a hidden power related to healing instead of his usual combat skills. This would change the whole dynamic of his relationships and the battles they face.
