Some tropes in this type of fanfiction include the 'damsel in distress' but with a twist. Maybe a Until Dawn character is in trouble and the Naruto character uses their unique skills to save them. There's also the 'rival turned lover' trope. Two characters who were initially competing for the main character's attention end up falling for each other instead. And the 'training montage' trope can be adapted. Instead of just Naruto - style training, it could be training to survive in the Until Dawn horror - filled environment.

There's also the 'slow - burn' romance trope where their relationship gradually develops from just being friends or acquaintances to something more romantic over the course of the fanfiction.
One popular theme is crossovers. Writers like to combine the characters and storylines from Naruto and Until Dawn.

A character might gain new abilities by combining the alchemy knowledge from Fullmetal Alchemist with the ninja skills from Naruto, all while being in a harem - type situation where different characters are attracted to their new - found power and unique personality.
