The story could also focus on Naruto getting caught and then having to face the consequences. His friends might be disappointed in him, and he'd have to work hard to regain their trust. He could learn important lessons about honesty and hard work during this process.
One way the story could be developed is by showing Naruto's reasons for becoming a pickpocketer. Maybe he's desperate to help his village in some way and sees pickpocketing as a quick solution. For example, he could be stealing from the rich to give to the poor in Konoha. This would add a Robin - Hood - like aspect to the story.
I'm not sure if there is such a specific 'naruto is a pickpocketer' fanfiction. Fanfictions can vary greatly in their themes and interpretations. Naruto is typically depicted as a heroic character in the original series, so this would be a very different and rather unorthodox take. It might explore a darker side of Naruto's character, perhaps in a world where he was forced into pickpocketing due to difficult circumstances.
One way the story could be developed is that Naruto's death could trigger a chain of events within the Hidden Leaf Village. His friends, like Sasuke, might be filled with guilt and anger. Sasuke could vow to avenge Naruto and start a dark path of seeking extreme power. Meanwhile, the village would be in mourning, and the younger generation would see Naruto as a martyr, inspiring them to train harder to protect the village in his memory.
In the fanfiction, their love story could be set in a new world where both Naruto's and Rias' universes collide. Maybe Naruto is on a mission in Rias' world and they meet by chance. Naruto's unique powers like the Rasengan would be a novelty in Rias' world, and she would be intrigued. As they get to know each other, they start to care for one another, and love blossoms. It could also involve some cultural exchanges between the two different settings.
One way could be through some sort of magical or cross - dimensional event. Maybe a powerful magic user or a godly artifact messes up the fabric of different mythologies and universes, bringing Naruto and Aphrodite together. Naruto, with his strong sense of loyalty and justice, might initially be very confused by Aphrodite's beauty and the concept of Greek gods.
In a fanfiction where Naruto is the villain, perhaps he becomes corrupted by the Nine - Tails' power. The constant struggle to control the fox within him finally takes a toll, and instead of fighting it, he gives in. He then uses the Nine - Tails' brute strength to wreak havoc. He might see the shinobi world as a place full of hypocrisy and decides to 'cleanse' it by force, attacking villages one by one, starting with Konoha, which he now views as a place of false promises.
Well, in this fanfiction, it could start with Naruto realizing his deep feelings for both Ino and Sakura over time. For the plot development, perhaps they go on a mission together where they have to rely on each other in a new way. Naruto might have to balance his time and affection between the two. Ino could help with strategic planning in their family life, and Sakura would take care of their health. Eventually, they form a unique family unit that is accepted in the village because of their combined contributions.
One way could be that Naruto has been in a time - loop for a thousand years. He keeps reliving certain events, trying to change the outcome each time. For example, he might be trying to prevent a great war that keeps happening no matter what he does in each loop.
Well, for this fanfiction, it might involve Naruto having to adapt to Artemis' world. He could teach her some of his ninja philosophies like never giving up and hard work. In return, Artemis could introduce Naruto to the magic and mystery of the Greek gods. Their marriage could be a symbol of the union between two very different but equally powerful cultures. They might face challenges from both the ninja world and the world of the gods, like jealousy from other gods or ninja who don't understand their relationship.
At first, Naruto might become more secretive. He'd be hiding his new 'profession' from his friends, which is very different from his usual open - natured self. This could cause some internal conflict as he doesn't like lying to them.
One way could be to make Naruto and his friends into SCP - like characters. Naruto's ability to use chakra could be seen as an anomalous power that needs to be studied and contained. The Leaf Village could be like a Foundation site, and they have to deal with other villages as if they were other 'threats' in the SCP universe. For example, Orochimaru could be a more menacing and SCP - style villain, with his experiments being even more grotesque and dangerous.
