In the fanfiction, it might be that Anko was training near a body of water and got caught in a strong undercurrent. Naruto, being a strong swimmer (maybe from his time training in various terrains), could jump in and pull her out. This would also be a chance for some character development, like Anko realizing Naruto's growth and Naruto showing his selfless nature.
Naruto could save Anko from a rogue ninja who infiltrated the training grounds. He'd use his ninja skills and his determination to keep Anko safe.
Perhaps Anko was poisoned during a training exercise involving dangerous plants or substances. Naruto, with his knowledge of herbs (maybe from his time with Tsunade), could find an antidote and save her. This would show his resourcefulness and how much he has grown as a ninja. He wouldn't just rely on his combat abilities but also on his other skills.
In this fanfiction scenario, Naruto might save Anko from a dangerous training accident. Maybe Anko was attempting a very difficult jutsu during training and lost control. Naruto, with his quick reflexes and growing power, could sense the danger and rush in to protect her. He might use his Rasengan or some new techniques he has learned to counter the threat.
One possibility is that Anko is poisoned during a mission. Naruto, having learned some medical ninjutsu from Tsunade, uses his skills to find an antidote and save her. He might have to search far and wide, facing various challenges along the way.
In a 'naruto saves anko' fanfiction, Naruto might find Anko in a dangerous situation like being trapped in a genjutsu by a rogue ninja. Naruto, with his strong will and Uzumaki chakra, could break the genjutsu and save her. He'd then comfort her and they might form a stronger bond, leading to Anko having more faith in the new generation of ninja.
One possible plot could be that Anko takes on a young and inexperienced ninja as her apprentice. She could start with basic physical training, like running through the forest while dodging various traps she sets up. Then, she might move on to teaching ninja techniques, especially those related to her own special skills in snake - based jutsu.
Perhaps Anko is trapped in a genjutsu and Naruto uses his own experience with breaking free from illusions to save her. He could sense her distress and use his chakra to disrupt the genjutsu, freeing Anko. This would show Naruto's growth and his ability to help those in need, even a more experienced ninja like Anko.
In a more comical fanfiction, Naruto might accidentally control Anko's eating habits. Let's say he uses a new jutsu that backfires and instead of affecting an enemy, it affects Anko. So, every time Naruto thinks about a certain food, Anko starts craving it and can't resist. This would lead to some really funny situations as Anko tries to fight against this strange control while Naruto is desperately trying to figure out how to undo the jutsu.
Well, they could start a new life in a far - off land. Maybe Naruto would learn some new techniques from the local ninjas there. And Anko could use her experience to help them build a small community.
In this fanfiction, they could become really good friends. Anko might help Naruto get over some of his insecurities. Maybe they'd have some adventures together in the village, like exploring some old, forgotten parts of Konoha. And Naruto could also introduce Anko to his other friends, like Shikamaru and Choji.
It could be a rogue ninja from Orochimaru's former experiments. This ninja might hold a grudge against Anko for betraying Orochimaru and decides to target her. Naruto would then have to face this powerful and vengeful enemy to save Anko.
One possibility is that Naruto would go into self - exile and train on his own. He might find new powers and allies outside the Hidden Leaf Village. With Anko, she could be conflicted. She might secretly help Naruto, believing that his banishment was unjust. This could lead to a whole new adventure where Naruto has to prove himself worthy without the support of his home village.
