Well, you could find fanfiction where the Naruto Academy teacher has a hidden power or a mysterious past. Or maybe ones where they're dealing with difficult students and finding unique ways to teach them.
One interesting storyline could be a new teacher coming to the Naruto academy with a mysterious past. This teacher might have unique abilities that they gradually reveal to the students, like a special jutsu related to nature control. For example, they could teach the students how to use chakra in a more efficient way to interact with the natural elements around them.
They add new perspectives. By focusing on the academy teachers, they show parts of the Naruto world that the original series might not have explored in depth. For example, we get to see how the academy functions from the teachers' point of view.
Some of these fanfictions could revolve around the relationships between the teachers and students. There might be a story where a teacher has to protect a student from a hidden danger in the academy. It shows a different side of the teacher - student dynamic, not just about academics but also about survival and trust.
Naruto's teaching style at Duel Academy would likely be energetic and motivational. He'd probably share his own experiences of growing up, facing challenges, and never giving up. His ninja training could also translate into teaching students discipline and perseverance in dueling.
Iruka is a really popular character to be written as a teacher in this kind of fanfiction. Since he already has a strong connection to Naruto and the other students in the original series, it's easy to expand on his role as a teacher. He can be shown teaching advanced lessons or dealing with new challenges in the academy.
Naruto would most likely inspire students who felt like outsiders. Just as he was an outcast in his own village at first, he'd recognize those students at Duel Academy who might not fit in with the more popular dueling groups. He'd give them the confidence to shine.
He would be like a big brother to the students. Since Naruto is not that much older than some of the students in terms of when he started his journey, he can easily relate to them. The students would look up to him and trust him quickly.
His teaching style might be very hands - on. Naruto is someone who has learned through experience, so he would likely encourage his students to do the same. He would probably tell them stories from his own adventures to make lessons more interesting.
There could be many interesting fanfiction ideas around Itachi being a teacher at Beacon Academy. Maybe he'd teach combat skills with his unique ninja abilities. He might be a very strict yet fair teacher, demanding high standards from his students.
