Who might be the main characters involved in a 'Naruto kidnapped by Kumo' fanfiction, aside from Naruto?

It could be Killer Bee. He's a very well - known and powerful ninja from Kumo. His unique fighting style and his status as a Jinchuriki would make him a great candidate to be the one who saves Naruto.

Well, Naruto is obviously one of the main characters. He's the central figure who brings his own skills and experiences from Konoha to Kumo. Then there would likely be some original Kumo characters created for the fanfiction. For example, a strong Kumo ninja who becomes Naruto's rival or friend. There might also be a Kumo leader or elder who plays an important role in how Naruto is received and integrated into the village.

Naruto might become more cautious. After being kidnapped, he realizes the world is more dangerous than he thought. He could start to be less impulsive and think more before acting.

He could form a strong bond with Killer Bee. They are both Jinchuriki, so they might share their experiences and train together. This could lead to a deeper understanding between Konoha and Kumo as a result of their friendship.

In this fanfiction, Naruto is the central figure. Alongside him, we might expect to see characters like the Raikage from Kumo. Their interactions and differences in ideologies could be a major part of the story. There could also be some minor characters from both Konoha and Kumo who help to build the background and context of Naruto's decision to abandon Kumo, like the shopkeepers or other common shinobi who witness the events leading up to this big decision.

Well, there could be an old butler who has been in the household for decades. He initially doubts Naruto's abilities but later becomes his mentor. And then there could be a group of thieves who target the wealthy household. Naruto has to use his butler skills and ninja skills to fend them off. And perhaps a childhood friend of Naruto's who visits him at the butler job and is amazed at how he has changed.

Boruto is often a popular character in such fanfiction. Since he also has the Jougan, stories might focus on his training with Naruto to master this power. Their father - son relationship can be explored in new ways as they both deal with the implications of the Jougan.

Adapting to a new ninja system could be a big challenge. Kumo may have different training methods, rules, and traditions compared to his home village. Naruto would need to learn and adjust quickly if he wants to survive there.

He could meet some rogue ninjas. These ninjas might either try to harm him or, in some cases, offer to help him on his journey. They might have their own reasons for being in the area between Konoha and Kumo.

Sakura could be a main character. She could be the one who encourages Naruto to get into dance in the first place. Maybe she has a secret love for dance and wants to share it with Naruto. She could also use her medical ninjutsu knowledge to help prevent dance - related injuries within the group.
