A plotline could be Naruto being assigned to protect a very important person from outside threats. But this person has a secret that could change the ninja world. Naruto has to figure out the secret while protecting the person, and also deal with other ANBU members who may have different motives.
Maybe Naruto discovers a conspiracy within Konoha while he's in the ANBU. It could involve some of the higher - ups trying to gain more power at the expense of the village's well - being. Naruto then has to decide whether to expose it and risk his position or try to solve it quietly.
A possible plotline is Naruto using his unorthodox methods to solve ANBU - related problems. His creativity and ability to think outside the box could lead to new strategies for the ANBU. He might come up with a new way to gather intelligence or take on a powerful enemy that the traditional ANBU methods couldn't handle.
In some fanfictions, Naruto in the ANBU could be involved in a special mission to uncover a long - hidden conspiracy within the Leaf Village. He would have to use his unique skills, like his shadow clones, in a more stealthy way. And along the way, he might make unexpected allies among the ANBU ranks who see his potential and different way of thinking.
Another plotline might be exploring Naruto's past more deeply. Maybe there are secrets about his parents that were never fully revealed in the original. In the fanfiction, he could discover something new about his father's time as Hokage or his mother's Uzumaki heritage that changes his perspective on his own powers and responsibilities.
One interesting plotline could be Naruto and Sakura being assigned a top - secret mission in the ANBU. They have to infiltrate an enemy organization together. Along the way, they discover new powers within themselves and also deepen their bond as comrades. Maybe Naruto unlocks a new form of his chakra while Sakura refines her medical ninjutsu to be used in combat situations in a more deadly way.
One interesting plotline could be Naruto's struggle to adapt to the strict and secretive ways of the ANBU. He's so used to his more open and brash style, so it's a big change. For example, he might have trouble with the stealth aspect at first.
Maybe they are part of an ANBU team tasked with protecting a very important person. Along the way, Hinata discovers a new power within herself, and Naruto is there to support and encourage her. This could lead to some tender moments between them and also show how they work together in a high - stakes ANBU operation. Their relationship could develop further as they face numerous challenges and threats together.
Perhaps a plotline where an Anbu member is revealed to have a personal connection to a major villain in the Naruto universe. This could create a lot of internal conflict within the village as they try to figure out how to deal with this revelation. For example, if the Anbu member is related to Orochimaru and has been secretly feeding him information, it would be a huge shock.
Another possible plotline is the relationships between the elite ANBU members. They might have a complex web of friendships, rivalries, or even romances that develop over the course of the story. This could add a lot of depth to the characters and the overall fanfic.
One interesting plotline could be Naruto having to deal with more complex political situations in the ninja world due to his age. Maybe he has to navigate treaties and alliances in a more hands - on way. Another could be his relationships with his friends evolving differently. For example, his bond with Sasuke might be more of an equal partnership in handling threats to the village, rather than the typical rivalry - turned - friendship we see in the canon.
One interesting storyline could be Sakura joining the Anbu and having to prove herself among the male - dominated group. She might face challenges like secrecy requirements and intense training, all while Naruto is on his own journey, and their paths cross in unexpected ways during missions.
