Naruto might also try to dig his way out. Using his chakra - enhanced strength, he could break through the walls or floors of the prison. However, he would have to be very careful not to be detected while doing this. He might do it at night when most of the guards are less vigilant. And he would need to cover up the evidence of his digging during the day.
He could use his transformation jutsu. He could transform into a guard or an inmate who has access to the prison exit areas. Then he could just walk out when the opportunity arises.
In this situation, Naruto could also use his ninja skills in a discreet way. For example, he could use his shadow clone jutsu to gather information without being noticed. He might discover that the ones who framed him are actually part of a larger conspiracy against the Hidden Leaf Village. So, his main goal would then not only be to get out of prison but also to expose this conspiracy.
Well, in the original Naruto storyline, Naruto is mainly focused on becoming Hokage and protecting the village from external threats. In the 'naruto framed prison fanfiction', he is suddenly in a position where he has to fight for his own freedom and reputation, which is a big deviation.
Well, one possibility could be that Naruto is framed for a crime he didn't commit and sent to the Blood Prison. There, he might face all kinds of dangerous inmates and tough prison guards. He would probably try to prove his innocence while also having to deal with the harsh prison environment and maybe some secret plots within the prison walls.
Sakura could use her medical ninjutsu to heal Naruto if he gets injured during the escape and also use her strength to fight off guards. She might also have some knowledge about the prison from her studies.
It could be the warden of the Blood Prison. He might be a corrupt figure who is using the prison for his own gain. He sees Naruto as a threat to his operations and tries to keep him locked up at all costs.
The main antagonist could be a rogue ninja who has infiltrated the village's council. This ninja could be secretly manipulating things behind the scenes to get Naruto sent to prison. He might have a vendetta against Naruto for some past encounter or just see him as a threat to his own evil plans.
It could be that Naruto is sent to prison as part of a political move. There are some ninja clans within the village who are jealous of his popularity and influence. They conspire to get him out of the way by making it seem like he's a threat to the village's security. In prison, Naruto discovers a hidden conspiracy within the prison walls that is related to the outside political turmoil and he has to find a way to expose it while also getting himself released.
One interesting idea could be the exploration of Naruto's character in a situation where he is wrongly accused and has to deal with the harsh prison environment. It might show his resilience and determination to prove his innocence.
One possible plot could be that Naruto was wrongly imprisoned. After being released, he has to prove his innocence while also dealing with the changed perception of him in the village. He might go on a journey to find out who framed him and along the way regain the trust of his friends and the villagers.
Well, one possibility could be that Naruto is wrongly accused of a crime in the Hidden Leaf Village and is sent to prison. There, he might meet other prisoners with unique abilities or stories. He could use his ninja skills in a different way, like trying to maintain peace among the inmates. Maybe he'd also be planning his escape while uncovering the real truth behind his false accusation.
