Maybe the new kid is from a different ninja village and has come to the high school in Konoha to learn their ways. He or she could face a lot of challenges fitting in, like not understanding the local customs or being bullied by some of the more aggressive students. This could lead to some great character development as the new kid overcomes these obstacles and makes friends.
One idea could be a sports competition at Konoha High School. Naruto could be on the track and field team, trying to break records.

One plot idea could be that Naruto, with his ninja skills, gets transferred to the High School DxD world.

You could write a fanfic where the two worlds collide due to a powerful magic or jutsu gone wrong. The characters from both Naruto and High School DxD have to team up to fix the problem. This would bring together different personalities and abilities. For instance, Issei's perverted nature could be a source of comedic relief while Naruto's determination could inspire the DxD characters to fight harder.
A plot could revolve around a group of avatar students from different tribes who are brought together for a special project. They initially clash due to their different cultural backgrounds and ways of using their avatar abilities. But as they face challenges together, they learn to work as a team and understand each other better. For example, a fire nation student might be impatient with the slow and methodical approach of a water tribe student when it comes to solving a problem related to their powers.
One idea could be that the Avengers are all students with different cliques. Iron Man could be the rich, popular kid who's a bit of a show - off with his high - tech gadgets.

Maybe there could be a plot where Annie is a new student at the high school. Armin is assigned to show her around. At first, Annie is cold and distant, but as Armin shares stories about the school and its traditions, she starts to open up and they form an unexpected friendship that could potentially turn into something more.
An Akatsuki High School fanfic could center around a school festival. The Akatsuki group could be in charge of one of the main attractions, like a haunted house or a concert. There could be drama within the group as they try to prepare for it, with different members having different ideas. Another idea is a story about a transfer student who has a strange power and the Akatsuki students are the only ones who seem to understand it. They then have to protect the transfer student from other students or outside forces who might want to use the power for their own gain.
One idea could be the characters from Kid Icarus and High School DxD teaming up to fight a common supernatural threat that combines the mythologies of both universes. For example, a demon - angel hybrid that also has ties to the Greek mythology in Kid Icarus.
