In many Naruto fanfics where his brother is jealous of him, it often stems from Naruto's growing popularity and power. Maybe the brother feels overshadowed. For example, if Naruto masters a new jutsu, the brother might envy the attention Naruto gets from their peers or sensei.
I'm not aware of the popularity of this specific fanfic. There are so many Naruto fanfics out there that it's hard to say whether this one has gained a large following.
This type of wuxia novel was very common. You can refer to some of the more popular works below:
1."Sword Comes"-Beacon Fire Playing with the Vassals
This was a story about the grudges of Jianghu. The protagonist was a swordsman named Sword Immortal Li. His brother Sword God Li was his opponent and enemy. After his father's death, Sword God Li was jealous of his younger brother's strength and status. He chased his younger brother out of the house and began to abuse him. Although Sword Immortal Li had been resisting and struggling, he eventually became his brother's accomplice and continued his life of being abused in the martial arts world.
[2]" Lord Snow Eagle "-An outsider
This was a modern wuxia novel about a young swordsman named Zhang Lei. His father was killed by an expert named Li Xueying, who was a competitor of his brother, Zhang Lei. Zhang Lei was expelled from the family by Li Xueying, but he did not give up. Instead, he became a famous swordsman in the Jianghu and started a life and death duel with Li Xueying.
3."Demonic Patriarch"-Ink Fragrance and Copper Stink
This was a xianxia wuxia novel about a young man named Wei WuXian. After his father passed away, he was forced to leave home and start his Jianghu career. He met some like-minded people in Jianghu and started a battle of morality and justice with them. In the process, he gradually found himself involved in a huge conspiracy and had to fight against some powerful enemies.
It might be a fan - created scenario where the author wanted to add an unexpected and comical element to the Naruto universe. Maybe it's part of a larger story about the relationship between Temari and Naruto, with this act being a catalyst for some sort of misunderstanding or adventure. However, without reading it, it's hard to say for sure.
One common theme could be protection. Just like a mother would protect her child, the Erza - like character in the fanfic might protect Naruto from various threats in the Naruto universe.
No. This kind of plot involves very improper and unethical relationships. The Naruto series is mainly about ninja's growth, friendship, and the pursuit of dreams. Fanfiction should be in line with the positive values of the original work rather than creating such abnormal and inappropriate stories.
I'm not sure which specific 'jealous reader fanfic' you're referring to. There are many fanfic platforms like Archive of Our Own (AO3), FanFiction.net etc. You can try searching for 'jealous reader' on these platforms to find relevant fanfics.
A 'chaelisa jealous fanfic' likely focuses on the relationship between Chaeyoung and Lisa in a context where jealousy plays a role. It could be about one of them being jealous of the other's popularity, or perhaps in a more romantic or friendship - centered scenario where jealousy arises due to attention from a third party. For example, if in the fanfic Lisa gets a lot of attention from a new trainee, Chaeyoung might start to feel jealous because she's used to having Lisa's full attention in their friendship.
No. Slavery is an inhumane and immoral concept, and applying it to fanfiction characters from a series like Naruto, which has positive values, is completely inappropriate.
One possible plot twist could be that they can actually interfere in Naruto's life in some unexpected ways. For instance, they might find a way to physically manifest and help Naruto in a crucial battle.
