There is a fanfic called 'Itachi and Sakura: Anbu Allies'. It delves deep into their Anbu experiences. The author does a wonderful job of depicting the Anbu world and how Sakura and Itachi's skills complement each other. It also has a great plot that keeps you hooked from start to finish.
A good fanfiction might explore how Female Naruto, with her goal of being recognized in the ANBU, catches Itachi's attention. Itachi, being a highly skilled and respected ANBU member, could act as a mentor to her in some aspects. He might teach her advanced combat techniques or how to better analyze the enemy. Their relationship could be filled with tension at first, as Naruto tries to prove herself to him, but later turns into a deep and meaningful connection.
Another option is Wattpad. Although it has a wide range of content, you can still find some great sakura itachi anbu fanfics there. You might need to be a bit more patient when searching as there is a lot of other content as well, but it's worth a try.
Definitely include Obito. His complex relationship with the Uchiha clan and his own history with the Anbu - like Akatsuki could create some interesting plot twists. Additionally, Kurenai could be added. She could be involved in a mission where she has to work with Itachi and Naruto. Her genjutsu skills might come in handy during a crucial part of the story. And don't forget about Rock Lee. His determination and unique fighting style could add some action - packed scenes to the fanfiction, especially if he gets involved in a mission with Itachi and Naruto.
One possible plotline is that Fem Naruto and Itachi are assigned to protect a valuable village asset. Along the way, they face numerous enemies and have to work together to overcome them. As they fight side by side, they start to respect each other's abilities more.
One plot idea could be exploring Itachi's time in the Anbu in more detail. For example, showing his first difficult missions and how they shaped his views on the village and his family. Maybe he has to make a choice between following a cruel order from the higher - ups in the Anbu or protecting an innocent. Another idea is a story where Naruto somehow gets a glimpse into Itachi's Anbu past through a special jutsu or a shared dream. This could lead to Naruto having a new understanding of Itachi and changing his perspective on him.
Naruto could develop a more solemn side. In the ANBU, he'd understand that his actions have far - reaching consequences for the village. He'd be more of a silent protector. Shikamaru would transform into a more decisive figure. His laid - back attitude would be replaced by a sense of duty and urgency. He'd be quicker to make tough calls in order to protect the village and Naruto, his friend, while in the ANBU.
In Itachi yaoi fanfiction, Itachi is often depicted as a complex and mysterious character. He is usually highly intelligent and powerful, which makes him an alluring figure in romantic or relationship - based stories. His loyalty, whether it be to his family, his village, or his love interest in the yaoi context, is also a common characteristic explored.
Well, Kakashi could train Naruto in combat skills specific to ANBU missions. This would include more lethal and precise attacks. He might also teach Naruto how to use different types of weapons that are common in ANBU operations. Maybe Kakashi would set up mock battles where Naruto has to face multiple opponents at once, just like in real ANBU scenarios.
One interesting storyline could be Sakura joining the Anbu and having to prove herself among the male - dominated group. She might face challenges like secrecy requirements and intense training, all while Naruto is on his own journey, and their paths cross in unexpected ways during missions.
