The story could be about Naruto finding a new family in Tifa. Since Naruto grew up without his parents, Tifa could offer him the motherly love he always craved. He might learn about Tifa's past and her own struggles, and in return, he could share his experiences from the ninja world. This would create a deep bond between them, and Naruto could start to see Tifa's world as his own, protecting it with his ninja powers.
His ninjutsu might be used in different ways. For instance, his Rasengan could be modified to work with the local materials or energy sources in Tifa's world. His ability to move quickly and stealthily would still be useful, but he might have to adapt to new terrains and environments. Maybe he'd use his chakra to enhance Tifa's fighting skills too.
One interesting storyline could be Naruto finding himself in the Final Fantasy VII world and teaming up with Tifa to fight a common enemy. Maybe they use Naruto's ninja skills and Tifa's martial arts to take on a powerful foe threatening both their worlds.
One popular storyline could be a crossover adventure. Imagine Naruto finding himself in the world of Final Fantasy VII where he meets Tifa. They might team up to fight a common enemy that is threatening both their worlds. Maybe a new villain emerges that combines the dark magic from Naruto's world with the technological threats of Tifa's world.
Well, obviously Naruto and Tifa are the most popular since they are the main focus of this fanfiction concept. Their unique personalities and abilities make them stand out. Naruto with his energetic and determined self, and Tifa with her tough yet caring nature.
Honestly, the idea of 'naruto x tifa lemon fanfiction' is a rather strange crossover. Naruto has its own unique world with ninjas and chakra, while Tifa is from a very different RPG world. While there may be some fan - created works that attempt this combination, it's likely that they are more of a novelty. You might have to search through various fanfiction websites and forums dedicated to both Naruto and Final Fantasy to find any, but don't expect it to be a common or mainstream type of fanfiction.
Perhaps in a 'naruto x tifa lemon fanfiction', Tifa could be transported to the Naruto world. She might initially struggle to adapt to the ninja - based society. Naruto, being the friendly and helpful character he is, would assist her. As they spend time together, they start to understand each other's strengths and weaknesses, which could lead to a deeper connection. However, they also have to deal with the politics and power struggles in the Naruto world that might threaten their relationship.
Since Naruto is a ninja from a world full of jutsu and Tifa is a strong - willed fighter from a more technological fantasy world, this fanfiction could be trying to blend their characteristics in an unexpected way. The 'oven' might be a metaphorical or literal device used to bring them together. For example, it could be a part of a scenario where they are forced to cooperate in a kitchen - related task (if it's a non - adult version). But again, it's difficult to know precisely without actually reading the fanfiction.
Since 'lemon' fanfictions are not suitable for general promotion, I suggest you look for non - adult Naruto and Tifa fanfictions. You could try searching for ones that focus on their unique abilities or how they might interact in a more platonic or adventure - based scenario. For example, a story about them teaming up to face a common enemy in a new, alternate universe.
If Kakashi adopted Naruto, it might change Naruto's path of development. He could receive earlier and more specialized training, and also have a stronger sense of family. This could have a significant impact on his personality and goals.
