In the new Princess Huanzhu, the scene of Xiao Jian saving Qinger from falling into the water happened in episode 40. At that time, Qinger and Xiao Jian had escaped onto the boat while fighting with the experts. However, there were a few experts hiding under the boat. Their sudden appearance caused Qinger to fall into the water. Xiao Jian was very anxious, but he couldn't find Qinger, so he went into the water to search. In the end, he found Qinger injured. Xiao Jian urgently saved Qinger and used artificial resuscitation to wake her up. This scene showed Xiao Jian's concern and worry for Qinger.
In this kind of fanfiction, perhaps Itachi uses his quick reflexes and ninja skills to catch Sakura as she's about to fall. Maybe she was in a dangerous situation like on a crumbling cliff or a collapsing building. Itachi, being the powerful ninja he is, swoops in just in time to prevent her from getting hurt.
It could be an unknown girl from a random village that Naruto just happens to pass by and save from a natural disaster, like a flood or a landslide. Naruto's quick reflexes and strength would allow him to rescue her.
Well, after Naruto saves the girl, she might become his friend. They could start training together, and she could learn some of Naruto's ninja skills. This would make her stronger and more confident, so she could stand up to the bullies on her own in the future.
The main characters are obviously Itachi and Sakura. Itachi, the complex and powerful Uchiha from the Naruto series, and Sakura, the intelligent and strong - willed kunoichi.
Another plot is where the girl is in some sort of self - imposed danger, like she's lost in a dangerous area or has made a deal with a bad guy. Naruto then has to use his wits and strength to not only save her physically but also get her out of the bad situation she got herself into. In some fanfictions, this also leads to the girl having a change of heart and becoming a better person thanks to Naruto's influence. This plot is interesting as it shows Naruto as a positive influence on others.
There's a fanfiction titled 'Saving the Girl from the Darkness'. In it, Naruto discovers a girl who has been trapped in a genjutsu for years. His own experience with loneliness and his strong will allow him to break through the genjutsu and save her. The story delves deep into Naruto's character, showing how his past traumas have made him more empathetic and determined to help those in need.
Perhaps the little girl is being targeted by a group of bandits. Naruto senses her distress and jumps into action. He battles the bandits using his shadow clone jutsu, overwhelming them. After saving her, he realizes she has no place to go. So, Naruto decides to take her back to Konoha. In Konoha, he helps her adjust to the new environment, and she in turn becomes a big fan of Naruto, following him around and learning about the ninja way from him.
It could be an original character created specifically for this fanfiction. Maybe she's a damsel in distress with a special power or a connection to Naruto's past that we don't know yet.
