One possible fanfiction idea could be that Danzo is forced into an arranged marriage with a female ninja from a powerful clan. She initially despises him because of his ruthless reputation but gradually discovers his complex motives and they develop an unexpected bond.
A fanfiction might explore a scenario where Danzo meets a female healer in Naruto. She is kind - hearted and tries to bring out the good in him. Their marriage is full of challenges as his dark past and actions constantly come between them. But over time, with her love and support, he begins to question his own morally ambiguous actions.
In a fanfiction, the female character could be a foreign ninja who comes to Konoha. Danzo, seeing her skills and potential influence, marries her as part of a political strategy. However, she challenges his traditional views and slowly changes his perspective on many things, like the importance of individual freedom within the village.
One possible scenario in a fanfiction could be that Danzo secretly admires a female ninja from a distance. Maybe she's a skilled healer in the village. He might be drawn to her kindness and the way she devotes herself to helping others, but his position and his secretive nature prevent him from expressing his feelings openly.
The plot could start with the village elders deciding that Danzo should marry a certain female ninja to strengthen alliances. The female is hesitant at first but realizes she can influence Danzo for the better. As they live together, she discovers his secrets and tries to steer him away from his more extreme actions.
One possible plot twist could be that Naruto has to struggle with the dark legacy of Danzo while still trying to uphold his own ideals of peace and friendship. He might face distrust from the village at first because of his relation to Danzo.
One possible motive could be power. Danzo was always obsessed with having power in Konoha. By experimenting on Naruto, who is the Jinchuriki of the Nine - Tails, he might have hoped to harness the power of the Tailed Beast in some way. Maybe he thought he could create a super - soldier or gain some unique abilities from Naruto's connection to the Nine - Tails.
Maybe it's out of guilt. In the original story, Danzo has done some shady things that might have affected Naruto indirectly. So in fanfiction, he could care about Naruto as a way to make amends.
The plot could involve Danzo falling in love with a female jonin. He might initially hide his feelings as he is a very private person. But as they are assigned on a mission together, they start to bond. He could be attracted to her combat skills and her strong will.
He'll likely lose his power and influence in the village. Once Naruto reveals his secrets, the villagers won't trust him anymore. His actions might be put on trial, and he could be exiled from the village.
In the Naruto universe, while it's highly unlikely in the official canon, in fanfiction, anything can be made possible. The Sharingan is a kekkei genkai exclusive to the Uchiha clan. Danzo had Sharingan in his arm which he obtained through rather unethical means. For Naruto to get it from him in fanfiction, it could be written through some sort of experimental jutsu gone wrong or right. Maybe a jutsu that was meant to transfer power ended up giving Naruto the Sharingan. However, this would completely change Naruto's power dynamics and character arc as the Sharingan comes with its own set of abilities like the ability to copy jutsu, predict movements, and use genjutsu.
There's a fanfic where Danzo tries to manipulate Naruto for his own political gain. However, Naruto, being the perceptive character he is, quickly catches on. This leads to a battle of wits between them. In the end, Naruto uses his own brand of talk - no - jutsu to make Danzo see the error of his ways and they end up working together to reform the village's political system.
In a fanfic where Danzo gives Naruto the Sharingan, it could lead to a very different Naruto. Naruto might gain new abilities and a new perspective on the Uchiha. He could potentially master the Sharingan quickly with his strong willpower, but he would also have to deal with the dark side of the Sharingan, like the curse of hatred that often comes with it.
