Some of the more hot - headed ANBU members might overreact and assume Naruto is a threat to the village. They could try to use force to get the stolen item back. However, the more level - headed ones might try to figure out Naruto's motives first. They might consider that Naruto could have a good reason for what he did, like if he thought the item was being misused by the ANBU.
The ANBU's reaction would also depend on what was stolen. If it was a minor item, they might be more lenient, but if it was something crucial like a secret scroll or a powerful weapon, they would be extremely serious. They would use all their skills, including their tracking and combat skills, to retrieve the item and punish Naruto according to the village's laws.
Well, one possibility is that Naruto is forced into pickpocketing the ANBU due to some dire situation. Maybe he needs to steal a special item from them to save a friend. For example, if his friend is poisoned and the only antidote is in the possession of an ANBU member, Naruto might see pickpocketing as the only option.
He may be surprised. Fanfictions can have some really out - there ideas that he might not have considered before. For instance, a fanfiction might have Naruto suddenly having a new, super - powerful jutsu that was never seen in the original series.
Naruto's adaptation to the Anbu in this fanfiction could be a complex process. At first, he'd probably struggle with the strict discipline and the need for secrecy. But his previous experiences in tough situations would come in handy. He'd gradually understand the importance of stealth and how to use his skills in a more covert way. He might also learn from the more experienced Anbu members, and his own determination would drive him to become a valuable part of the Anbu.
At first, Naruto might be angry. He's put in a lot of effort to get into the ANBU and prove himself. So being forced out would feel like a slap in the face. He might go on a rant about how unfair it is.
Naruto could develop a more solemn side. In the ANBU, he'd understand that his actions have far - reaching consequences for the village. He'd be more of a silent protector. Shikamaru would transform into a more decisive figure. His laid - back attitude would be replaced by a sense of duty and urgency. He'd be quicker to make tough calls in order to protect the village and Naruto, his friend, while in the ANBU.
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.
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.
Naruto would probably be overjoyed at first. After all, he has always longed for his parents. But with the sister, it might be a bit more complicated. He might be a bit cautious, not sure how to interact with her at first. But eventually, he would welcome her into his life with open arms.
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.
Yes, there are likely fanfictions out there with such a plot. In the Naruto universe, the ANBU are elite ninja, and having Naruto as an undercover ANBU could lead to really interesting storylines. For example, he could be gathering intelligence on internal threats to Konoha while still maintaining his normal ninja duties on the surface.
