People like it because it shows a different side of Sakura's character. Usually, Naruto is seen as the protector, but in these fanfictions, Sakura gets to shine in that role.
There is a fanfiction where Naruto protects Sakura during a time - travel adventure. They go back in time and Naruto has to use his knowledge of the future to keep Sakura safe from past threats. Another good one is when Naruto protects Sakura from a mind - controlling jutsu. He uses his own strong will to break the jutsu's hold on her and then protects her from the caster. One more is a story where Naruto and Sakura are on an island and Naruto has to fend off sea monsters to protect Sakura.
One popular 'Sakura Protects Naruto' fanfiction might be where Sakura uses her medical skills to save Naruto from a life - threatening injury during a battle. In this type of story, she could be the sole reason he survives and is able to continue fighting for the village.
Another reason is that it allows for creative interpretations. Fans can create their own versions of how Sakura protects Sarada. It could be in a world full of new threats or in a more slice - of - life setting. The flexibility in storytelling attracts a lot of fans who want to contribute their own ideas to this relationship.
There's not enough information to determine exactly who Gai is. It could be a fan, a self - appointed protector within the fanfiction community, or perhaps someone with a personal connection to the Sakura concept in the fanfiction.
Well, it could be about Sakura taking on the role of protecting Akamaru. Maybe in a dangerous situation where Akamaru is in harm's way and Sakura uses her skills, like her medical ninjutsu or combat abilities to keep Akamaru safe. It might also involve their relationship, perhaps how Sakura has a special bond with Akamaru and feels responsible for his well - being.
Another interesting one is 'Protecting Sakura: Naruto's Vow'. In this fanfic, Naruto makes a solemn vow to always protect Sakura after she nearly loses her life in a battle against a rogue ninja. He trains extra hard and devises a whole new strategy to ensure her safety at all times.
I'm not entirely sure without more context. 'Gai' might be a name or something specific in a certain community. 'Protects' is clear, and'sakura fanfiction' likely refers to fan - created fictional works related to something named Sakura. It could mean that this 'gai' entity is safeguarding the Sakura - related fanfiction from something like deletion, criticism, or other threats.
Some fanfictions might introduce new original antagonists. These could be powerful rogue ninjas who are after Sakura for her medical skills or some special power she might have in that particular fanfiction. They would then be the main threats that Itachi has to deal with to protect her.
Love is a common theme. Sasuke's protection often stems from his deep, unspoken love for Sakura. It might not be openly expressed at first, but his actions speak volumes.
