One possible fanfiction could be about Sakura joining an Anbu team that has Itachi and Shisui. Maybe Sakura is a new recruit and she has to learn from the two experienced shinobi. Itachi could be the calm and collected leader, while Shisui is the more easy - going one who helps Sakura adjust to the harsh Anbu lifestyle.
In the fanfiction, there could be a conflict within the team. Maybe there is a misunderstanding between Itachi and Shisui regarding a mission strategy. Sakura, being the mediator, tries to resolve the issue. She uses her understanding of both of them to bring them back together. This not only strengthens the bond within the team but also makes them more effective in future missions.
Shisui is known for his cheerful and friendly nature. He would likely be the one to break the ice with Sakura and make her feel welcome in the Anbu team. Itachi, on the other hand, is more reserved. He would respect Sakura's skills but might not be as openly friendly at first. Sakura, being strong - willed, would earn their respect over time with her determination and medical knowledge.
One idea could be that Sakura, while on a mission with the Anbu team led by Itachi and Shisui, discovers a hidden jutsu that could change the balance of power in the ninja world. The Anbu team then has to protect her as she tries to master it and keep it from falling into the wrong hands.
There are quite a few good writers out there. One way to find them is to search for fanfiction communities dedicated to Naruto (since these characters are from Naruto). In these communities, people often recommend their favorite writers. Some writers are known for their in - depth characterizations of Itachi, Sakura and Shisui. They make the characters feel real and add new dimensions to their relationships. You might also want to follow some fanfiction blogs on Tumblr that often share and promote great fanfictions about these characters.
A common theme is time - travel. For instance, Sakura might travel back in time and meet a younger Itachi and Shisui. This allows for interesting plot developments as she tries to change the future or just understand their past better. Also, the theme of redemption can be found. Maybe Itachi or Shisui have made some mistakes in their past and Sakura helps them find redemption through their interactions with her.
Sakura's amusement could actually make Shisui more likely to continue annoying Itachi. Since she finds it funny, Shisui might see it as a sign that his actions are acceptable and entertaining. This could potentially strain the relationship between Shisui and Itachi further if Itachi doesn't like being the target of Shisui's annoyance.
Well, I know that many fanfiction stories often explore unique relationships between these characters. For example, there could be a story where Sakura has to team up with Itachi and Shisui to face a powerful enemy. In these fanfictions, the authors might give Sakura new powers or abilities to make the story more interesting. Another common theme could be a love triangle between the three, which can lead to some really intense and emotional storylines.
One idea could be a story where Sakura, as a skilled medic, is tasked with treating Itachi and Shisui during a difficult mission. She discovers their complex pasts and bonds with them over time, leading to new alliances and friendships.
She could develop a more strategic mind. Shisui and Itachi are known for their intelligence in battle. Sakura would learn from them how to analyze situations better, plan ahead, and anticipate her opponents' moves. This would make her a more well - rounded ninja rather than just relying on her brute strength.
