It could be Orochimaru. Since Orochimaru has a long - standing feud with Jiraiya and is always up to no good. If Naruto ditches Jiraiya, Orochimaru might see this as an opportunity to manipulate Naruto. He could try to convince Naruto that Jiraiya was holding him back and that he can offer Naruto more power, all while having his own evil plans for Naruto.
Most likely not. Songs like 'Death Bed' often draw inspiration from various sources but not necessarily from a single true story. It might be a combination of emotions, fictional scenarios, or general themes.
This was a tricky problem because the death notice and the farewell song were specific scenes in the novel and usually would not appear again. However, some novelists may set up a reversal or unexpected plot in the novel to make the readers unexpected characters or scenes appear. Therefore, if one wanted to determine if there were other plots in the novel, one needed to read the entire novel to understand the author's plot and idea.
There may be some interesting Kushina and Jiraiya fanfictions. You could search on platforms like Archive of Our Own or FanFiction.net. When looking, pay attention to the tags and summaries to find ones that focus on the elements you're interested in, such as their friendship or potential collaborations in the story.
One great fanfic could be about their adventures before Naruto was born. It might explore their relationship dynamics, how they trained together and supported each other. Maybe in this fanfic, Jiraiya tries to convince Tsunade to take on more dangerous missions with him, showing his trust in her abilities.
It could lead to Naruto becoming even stronger and more skilled than in the original story. Jiraiya's training methods might unlock new powers for him.
Another good place could be some Naruto - focused forums. There are often threads dedicated to sharing and discussing fanfictions. Members of these forums might recommend some great Tsunade and Jiraiya fanfictions that they have read. It's also a great way to interact with other fans who have similar interests.
Adventure - themed fanfictions are also common. Since they are both powerful ninjas, authors like to create stories where Tsunade and Jiraiya go on dangerous missions together. These stories might include battles against powerful enemies and the development of their relationship during the course of the adventure. It could be about how they learn to trust and rely on each other more during these tough situations.
