There's a fanfiction I read once that explored how Kushina's fiery personality and Hiruzen's wisdom could combine to solve a major crisis in the village. It was really interesting to see how the author developed their characters and the unique bond that formed between them.
One common theme is the passing of knowledge. Hiruzen, with his years of experience, can pass on wisdom to Kushina. Another is the protection of the village. They both care deeply about the Hidden Leaf and stories often revolve around them working together to safeguard it.
Yes, there are quite a few. Some fanfictions might focus on their interactions within the Hidden Leaf Village. For example, they could be involved in a joint mission where Hiruzen, as the experienced Hokage, imparts some of his wisdom to Kushina. This could lead to a great story of mentorship and friendship.
One common theme is friendship. Given their different positions in the village, a story could be built around how they become friends. Another theme could be protection. Since Kushina is a jinchuriki, Hiruzen might be involved in protecting her from those who would seek to use her power for evil.
Maybe Naruto is put in a situation where he feels that Hiruzen's way of handling things is the best option. For instance, if there is a major crisis in the village that requires a more traditional and experienced approach, Naruto might choose to act like Hiruzen. Also, he could be influenced by the stories he has heard about Hiruzen and wants to fill his shoes in a way.
One aspect that could be delved into is their different leadership styles. Hiruzen was more of a traditional leader, while Tsunade brought a new perspective. Fanfiction might show how they interacted regarding village policies and decision - making. For example, they could have had debates on how to handle the ninja academy or allocate resources.
Perhaps in this fanfiction, Naruto has some sort of special power or transformation that he unlocks just in time to face Orochimaru. It could be related to his Nine - Tails chakra in a new and unique way. He uses this power to break through Orochimaru's defenses and save Hiruzen. Naruto might also use his knowledge of Orochimaru's weaknesses that he has learned either from Jiraiya or from his own past encounters with Orochimaru's minions.
These interactions might also be important in terms of character development. For Tsunade, her relationship with Hiruzen could help her overcome her past traumas and hesitations about taking on the role of Hokage. And for Hiruzen, it could be a way to leave a lasting impact on the village through Tsunade.
I'm not entirely sure specifically as it depends on the individual work. But generally, it might involve creating fictional stories centered around characters named Naruko and Hiruzen. It could explore their relationship, adventures they might have together, or different scenarios in a made - up universe.
One challenge is the time gap between their eras. Sakura is from a more modern time in the Naruto series, while Hiruzen is from an earlier generation. So, it can be difficult to create a believable scenario where they interact in a way that doesn't seem forced.
