In this kind of fanfiction, Sasuke could die from a sneak attack. He might be so focused on his main target during the Wave mission that he doesn't notice another hidden threat. And this hidden enemy could strike him when he least expects it, leading to his death. For example, an assassin could be hired to specifically target Sasuke and use some sort of poison or a deadly jutsu that he can't defend against in time.
The team dynamic would be completely shattered. Sakura would be devastated as Sasuke was someone she had strong feelings for. Kakashi too would feel responsible for not being able to protect Sasuke. This could lead to the team splitting up or at least going through a long period of internal turmoil and lack of cooperation. And it might also change the way the village views their team, perhaps with disappointment or a sense of loss.
One possible reason could be that he overestimated his abilities during a battle in the Wave arc. Maybe he took on an enemy that was much stronger than he thought and got fatally injured. Another reason could be that he sacrificed himself to save Naruto or someone else. It's also possible that there was some sort of betrayal within the group they were with, and Sasuke was caught off - guard and killed.
Well, if Sasuke dies in this fanfiction set in the Wave arc, Naruto would likely become more determined to avenge him. He might also grow more solemn and focused on his ninja training, realizing the fragility of life. His view of the world could shift from being a bit more carefree to a darker, more serious one as he grapples with the loss of his friend and rival.
There's no way to know the author just from this title. Fanfiction is a vast world with countless creators. It could be a relatively unknown writer who just wanted to explore this unique and somewhat dark concept. Maybe it was written by someone who was experimenting with different ways to tell a story within the existing fictional universe related to Sakura.
In this kind of fanfiction, the death of Sakura in a wave might be used to create a sense of tragedy. It could be a way to explore themes like loss, the power of nature, or the fragility of life. For example, it might show how a character like Sakura, who could be seen as innocent or full of life, is suddenly taken away by the force of the wave, which can be a very powerful and emotional concept.
I'm not sure specifically as there could be many different versions of such a fanfic. But generally, it might involve Naruto facing some overwhelming danger in the Wave arc that leads to his death, perhaps a more powerful enemy than in the original story or a failed mission that costs him his life.
I'm not sure specifically as there could be many different 'sakura dies in wave fanfic' out there. It might involve a story where a character named Sakura meets her end in a wave - related scenario, perhaps a tsunami or a powerful ocean wave in a fictional world.
Sasuke might be in shock at first. He can't believe that Naruto is dying in his arms. He may feel a great sense of guilt, thinking that he could have done more to prevent it.
Since I don't know the specific fanfic, Sakura is likely one of the main characters as it's in the title. There may also be characters related to her, like her friends or family who are affected by her death in the wave.
