A story could revolve around an Anbu agent who loses his mask during a mission. As he tries to retrieve it, he has to face his own identity without the mask's anonymity. It could explore how the mask is not just a tool for concealment but also a part of his psychological armor.
Perhaps a fanfiction where an Anbu with a unique mask is framed for a crime he didn't commit. He has to use his skills and the reputation associated with his mask to clear his name while also uncovering a conspiracy within the Anbu ranks.
In a more complex scenario, Naruto could be influenced by an outside force. Let's say an enemy of Konoha uses mind - control or some form of manipulation on Naruto. They make him believe that the ANBU is the enemy of the village and that he needs to take them down. As he betrays the ANBU, he slowly starts to realize that he's been used, but by then he's already in too deep and has to find a way to fix the situation and regain the trust of his friends and the village.
One idea could be a story where a young ninja discovers an ancient ANBU tattoo on their body that holds a hidden power. They then embark on a journey to find out the origin of the tattoo and how to control its power. Maybe it's linked to a long - lost ANBU clan.
An Anbu character could have an arc where she is initially very confident in her abilities while wearing the mask. But then she loses her mask in a battle and has to face her opponents without the psychological boost it gives her. This makes her realize that she has been relying too much on the mask's symbolism and she has to build true inner strength.
One idea could be Naruto going on an Anbu mission where Hinata secretly follows him to protect him. Another could be an alternate universe where Naruto and Hinata are both in the Anbu and they have to work together to solve a mystery within the Hidden Leaf. Or perhaps a story where Naruto is in the Anbu and Hinata is trying to get his attention in a more covert way than usual.
One idea could be that the blind Anbu has a special ability to sense chakra in a unique way. For example, they can detect the slightest change in an enemy's chakra, even if they can't see them physically. This gives them an edge in battle.
A really interesting plot could be that the ANBU commander discovers a long - forgotten prophecy that somehow involves the ANBU and the future of the Hidden Leaf Village. They then embark on a journey to understand the prophecy better, facing many obstacles along the way, including opposition from some within the village who fear the changes the prophecy might bring.
One plot idea could be a Kitsune Anbu agent who has a special mission to protect Naruto but has to hide their true Kitsune nature from him at first. Another could be a Kitsune Anbu being sent to infiltrate an enemy organization that is targeting Naruto and his friends. Or perhaps a story where a Kitsune Anbu discovers a long - lost secret about Naruto's family that has been hidden by the Anbu for years.
One idea could be exploring Itachi's time in ANBU and how Naruto might have influenced his decisions secretly. Maybe Naruto, with his unique way of seeing people, could have made Itachi question his path in the ANBU more deeply.
Another plot could involve the Anbu team being tasked with protecting a young and powerful ninja from another village who has valuable knowledge. Along the way, they form an unexpected bond with this ninja and learn new techniques from them.
One idea could be exploring the character's past in the ANBU in more detail. For example, showing the difficult missions they had to undertake and how it shaped them.
