I'm not sure which specific 'akatsuki tobi love story' you are referring to. Akatsuki is a group in Naruto. Tobi was a character in it. Maybe it could be a fan - made love story between a member of Akatsuki and Tobi. Without more context, it's hard to tell the exact story.
Well, 'Tobi's Redemption' is an interesting 'akatsuki tobi fanfic'. It shows a different side of Tobi, perhaps a more sympathetic one. 'Akatsuki Tobi: The Untold Stories' is also good as it reveals some backstories that are not shown in the original series. And don't forget about 'Tobi's Alliances' which focuses on his relationships and alliances within the Akatsuki.
Well, if we go by the name, the main character is Tobi for sure. And as for the other part of the love story, it could be any of the Akatsuki members. It could be Konan, who has her own charm and powers. Or it could be someone like Kisame, though that would be a really strange pairing. But in fan - made stories, the possibilities are endless when it comes to pairing Tobi with an Akatsuki member.
To write an 'akatsuki tobi fanfic', start by brainstorming ideas. Think about what makes Tobi unique. Maybe you want to explore his connection to other Akatsuki members more deeply. You should also research the Akatsuki as a whole. Their goals, their hierarchy, etc. When writing, use vivid descriptions to bring the story to life. For instance, describe Tobi's movements and his signature jutsu. Also, make sure your story has a clear theme, like loyalty or betrayal.
Some might see it as an opportunity to get closer to understanding Tobi's motives. Hidden Leaf Village, Naruto's home, would be torn between trying to save him and having to protect themselves from him. The younger generation who looked up to Naruto would be heartbroken and confused, and the older shinobi would be worried about the future of the ninja world with Naruto in this new, dangerous state.
The Akatsuki members themselves would have mixed reactions. Some, like Itachi (if he were still alive in the fanfic), might see Naruto as a potential asset but also a threat to their long - term goals. Kisame might be amused by Naruto's presence and see him as a new source of entertainment. Meanwhile, the Leaf Village elders would be outraged. They would see Naruto as a traitor and start devising plans to either bring him back or eliminate him.
Sakura might be very cautious at first. She's heard about the Akatsuki's bad reputation, so she would keep her distance. For example, if she sees an Akatsuki member lurking around school, she'd probably try to avoid them and alert the proper authorities, like the school security or her ninja mentors if it's in a Naruto - like world with ninja training in high school.
Some members like Itachi might be very calm and just observe quietly. He would probably analyze the stories, thinking about how the characters are developed and what the underlying themes are.
Naruto would probably be initially cautious but also curious. He has a knack for seeing the good in people, so he might try to befriend the Akatsuki sister. Kurenai, on the other hand, would be more guarded. She is a more experienced ninja and would be wary of any Akatsuki member. But she also might see an opportunity to gain intel from the sister.
