Naruto would be the main character without a doubt. Shikamaru could be in the fanfiction too. He is known for his laid - back yet intelligent nature, and in the 'Handsome Academy', he could be using his wits to get by in the challenges related to handsomeness. Ino might also be a main character. She is very confident and could be giving tough competition to others in terms of beauty and charm at the academy.
In this fanfiction, Naruto is the central figure. Hinata could be another main character. She has always had a crush on Naruto, and in the 'Handsome Academy', she could be shyly trying to get closer to him while also improving her own charm. Kakashi could be a teacher at the academy. He has his own unique charm and could be guiding the students in the ways of the academy, which includes both academic and 'handsome - related' teachings.
In a 'Naruto Handsome Academy' fanfiction, the plot might revolve around Naruto being scouted for this academy because of his latent good looks. Once there, he discovers that there are different classes, like the 'Handsome Combat' class where they learn to fight gracefully. He could also get into trouble for not conforming to the strict beauty standards at first, but then he starts to influence the academy to value inner beauty as well.
Obviously Naruto would be one of the main characters. Since it's set in an academy, his classmates like Sasuke and Sakura would likely also be important characters. The academy teachers, such as Iruka - sensei, would probably play significant roles as well.
It's hard to say exactly as it's fanfiction, but it could include Naruto - like characters with enhanced, god - like powers. Maybe some new characters created specifically for this fanfic who are leaders or star students in the godlike academy.
It could be Naruto and Ichigo. Since it's a crossover of the two series, these two popular protagonists would likely play important roles in the fanfiction.
Obviously, Naruto and Sakura are the main characters. Naruto, with his determination and unique skills, and Sakura, with her intelligence and growing strength in the academy setting.
Obviously Naruto would be one of the main characters. He would be the one bringing his ninja world charm and skills to Gaia Academy. Another could be a student at Gaia Academy who befriends Naruto early on, like a smart girl who helps him understand the academy's rules and curriculum.
The bijuu are the main characters as they are the focus of the 'goes to Yuki Academy' part. However, depending on how the story unfolds, there might be some side characters like the academy's janitor who has some secret knowledge about the bijuu and ends up helping them in unexpected ways, but still, the bijuu are the central figures.
Naruto himself is extremely popular in Naruto Academy Fanfiction. His determination and unique personality make him a central figure in many stories. Sasuke is also popular as his rival, and many fanfictions explore their relationship further within the academy setting.
Popular characters include Shikamaru. He could be in a fanfiction where he pretends to be even more lazy than he really is to deceive his opponents or teachers. Ino might be a character who pretends to be best friends with someone she doesn't really like to gain some information. And Kiba, along with Akamaru, could pretend to be a different type of ninja - animal duo to surprise their classmates during a practical exam.
Growth is also important. They both grow as ninjas and as people during their academy days. They overcome their weaknesses and become stronger, both physically and mentally. For example, Naruto learns to control his chakra better, and Sakura becomes more confident in her abilities.
