I'm not sure specifically as I haven't read that particular fanfiction. But generally, a 'Sasuke Oiroke no Jutsu' in fanfiction might involve Sasuke in some sort of comical or unique situation related to the Oiroke no Jutsu, which is the Sexy Jutsu in the Naruto universe. However, without reading it, it's hard to say more precisely.
Sakura could be a bit angry at first. She has grown and become more independent during his absence. When Sasuke shows regret, she may lash out, expressing all the pain and frustration she felt during his long absence, but deep down she still has feelings for him.
He could practice in secret locations where no one can see him. For example, in an abandoned cave or a hidden part of the forest. That way, no one will know about the new jutsu he's developing.
One consequence could be a change in the relationship between Naruto and Sasuke. Sasuke might become more enraged or, on the other hand, he could start to question his actions. As for Naruto and Ami, their bond might grow stronger. Ami would likely be very grateful to Naruto, and this could lead to a closer friendship or even something more in the future of the fanfiction.
Well, it depends on the specific setting of the fanfiction. If it's set in a modern - day AU (alternate universe) where Naruto and Sasuke still have their powers, Naruto could be using his enhanced speed to reach Amy in time. He might also have some sort of new power or ability that we haven't seen in the original series that helps him save Amy more effectively. For example, he could have a power that allows him to absorb or deflect the fireball instead of just dodging it.
Yes, there might be such fanfictions out there. Fanfiction is a creative space where all kinds of wild and unique ideas can be explored. Writers often come up with unusual relationships between characters just for the sake of exploring different storylines and character dynamics.
Maybe he found some hidden scrolls left by his mother. These scrolls could have contained the details of her jutsu. Naruto, being the curious and determined ninja he is, would have studied these scrolls carefully and learned the jutsu.
Well, in the fanfiction, Naruto might use his own jutsu, like the Rasengan. He could quickly form it and counter Sasuke's fireball, thus saving Ami. Maybe Naruto's quick reflexes and his determination to protect Ami play a big role here.
One way could be that Naruto uses his wind - style jutsu. He manipulates the wind to create a gust strong enough to blow Sasuke's fireball off course, away from AM. This would be a display of Naruto's control over different elements.
In this kind of fanfiction, Naruto might use his own jutsu like the Rasengan. He could quickly form the Rasengan and counter Sasuke's fireball, dissipating it before it reaches AM. This would require Naruto's quick reflexes and mastery over his chakra control.
