In some fanfictions, they might develop a more equal partnership. Naruto has grown a lot and in the ANBU, they are both elite ninjas. They could rely on each other's strengths. Naruto with his raw power and Kakashi with his intelligence and experience. They would share their thoughts and feelings more openly, and their bond would become stronger as they face dangerous missions together. For example, during a mission where they are outnumbered, Naruto might come up with a bold plan based on his intuition, and Kakashi would support him wholeheartedly because he trusts Naruto's abilities.
They could develop a mentor - apprentice relationship. Kakashi already has some experience mentoring Naruto, and in the ANBU setting, he could teach Naruto more advanced and stealthy techniques. Naruto would look up to Kakashi even more and try to learn as much as he can.
They would probably have a very close and mentor - student relationship. Kakashi, being Naruto's caretaker and trainer, would be like a father figure to him. Naruto would look up to Kakashi and trust his guidance completely.
As they go on more missions together, they could develop a deeper bond of trust. Sakura might save Kakashi from a dangerous situation, like a trap set by the enemy. This would make Kakashi see her as an equal rather than just a protege. They would start to rely on each other more and more, sharing their thoughts and fears during missions.
Well, Kakashi could train Naruto in combat skills specific to ANBU missions. This would include more lethal and precise attacks. He might also teach Naruto how to use different types of weapons that are common in ANBU operations. Maybe Kakashi would set up mock battles where Naruto has to face multiple opponents at once, just like in real ANBU scenarios.
Their relationship would likely become very close. Naruto would probably start to see Kakashi as a father figure. Kakashi, in turn, would become more protective of Naruto.
Their relationship in Anbu fanfiction can be really interesting. It could be a relationship of mutual respect. Kakashi respects Sakura's determination and Sakura respects Kakashi's skills and experience. They might work together on various Anbu missions, with Kakashi leading and Sakura following his lead at first. But as time goes on, Sakura could start to contribute more equally.
Flashbacks can also play a crucial role. By showing their past interactions, even if brief, it can add depth to their relationship. Maybe a flashback of a time when Naruto was a child and Kakashi saved him secretly in his Anbu days. This would create an unspoken bond that could be explored further in the fanfiction.
Their relationship could become more competitive. Since ANBU is a place for elite ninjas, they might constantly strive to outdo each other in missions.
Their relationship could develop as they are paired on dangerous Anbu missions. They would rely on each other for survival, which would deepen their bond. For example, Naruto might start to see Hinata in a new light when she saves his life during a mission.
Their relationship might become more of a strategic partnership. Naruto would respect Kurama's power and knowledge more deeply as they face the complex and dangerous ANBU missions together.
One common theme is loyalty. In the ANBU, loyalty to the village is of utmost importance. Fanfictions often explore how Naruto and Kakashi uphold or struggle with this loyalty. For example, they might face a situation where their loyalty to each other conflicts with their loyalty to the village.
