In this fanfiction, Itachi and Shisui could be assigned to train Sakura in some ANBU - specific skills. Sakura, eager to prove herself, faces many challenges. Itachi teaches her about the mental strength required in the ANBU, while Shisui focuses on physical combat techniques. Along the way, they form a strong bond and go on a mission together where Sakura uses her newly learned skills to help them defeat a powerful enemy that was threatening the Leaf Village.
One possible plot could be that Itachi and Shisui are on a mission in the ANBU and they cross paths with Sakura who is also on a mission related to a medical emergency in a war - torn area. They initially have some misunderstandings as Sakura is not used to the ANBU's way of doing things, but eventually they work together. Itachi and Shisui use their combat skills while Sakura uses her medical ninjutsu to save a village from a hidden enemy's attack.
One possible plot could be a story where Sakura, Itachi, and Shisui are all part of the ANBU. Itachi and Shisui could be mentoring Sakura in the ways of the ANBU. They might go on a dangerous mission together, facing powerful enemies. Shisui could use his unique abilities like Kotoamatsukami to gain an advantage, while Itachi's Sharingan and combat skills are also crucial. Sakura, with her medical ninjutsu and growing combat skills, could prove to be a valuable asset in the team.
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.
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.
Well, one possibility could be that they are on a mission together. Sakura's medical skills could come in handy when Itachi or Shisui get injured. And they might face a powerful enemy that requires all of their skills combined to defeat. Maybe Itachi's Sharingan and Shisui's unique abilities, along with Sakura's strength and intelligence, make for an interesting dynamic.
A rogue ninja from a rival village could be the main antagonist. He might be after the secrets of the Sharingan that Itachi and Shisui possess. And he sees Sakura as an obstacle when she tries to protect her comrades. He could have some powerful and forbidden jutsu that makes him a formidable foe for the trio.
A really interesting plot twist could be that Shisui and Itachi find out that Sakura has a connection to an ancient and powerful clan that they didn't know about before. This connection could bring in new elements to the training, like special techniques or a deeper understanding of the ninja world that they have to incorporate into her training.
Well, perhaps Sakura is in a really bad mood and Shisui is just in the wrong place at the wrong time. She starts pummeling him and Itachi, who has a rather dry sense of humor, is amused by the whole situation. It could also be that Shisui has been teasing Sakura a lot and she finally snaps and goes after him, with Itachi looking on with that amused look on his face.
Well, perhaps the plot could involve Shisui constantly playing pranks on Itachi, which Sakura finds hilarious. Maybe Shisui hides Itachi's training tools, and Itachi's confused and flustered reactions make Sakura giggle. It could also be that Shisui teases Itachi about his secret crush, if he has one, and Sakura enjoys seeing Itachi being so out of his element.
In this fanfiction, a possible plot highlight could be a training tournament among Sakura, Shisui, and Itachi. This would allow Sakura to test her skills against two of the most powerful shinobi. Itachi's sharingan and Shisui's body - flicker technique would pose great challenges for Sakura. However, through her own strength and the knowledge she has gained from Tsunade, she could hold her own. This kind of competition would also strengthen their bonds as they respect each other's abilities more after seeing them in action.
