No. Such a fanfic is not ethical as it promotes a very negative and immoral concept. Naruto as a character is a symbol of hope and positive values, and turning him into an enslaver goes against the basic ethical principles of the Naruto franchise.
No. Enslavement is an unethical and immoral concept, and applying it to the Naruto characters in a fanfic is inappropriate. The Naruto series is about positive values like friendship and teamwork.
Yes, there are likely Naruto fanfics that focus on Shizune. The 'Naruto' fandom is vast, and many characters get their own storylines in fan - created works. You can try searching on fanfic websites like FanFiction.net or Archive of Our Own.
I'm not aware of any official 'naruto enslaves sakura fanfic' as it goes against the positive themes of the original Naruto series. Fanfics with such disturbing concepts are not in line with the spirit of the show which promotes friendship, growth, and respect among characters.
Shizune is an important side character in the Naruto series. Fanfics about her can range from romantic pairings (although not always) to stories that expand on her role in the medical ninja field. Some fanfics might give her more screen time, so to speak, by creating scenarios where she has to use her skills in unique ways or face challenges that test her abilities and character.
In a 'naruto enslaves everyone fanfic', it might involve Naruto using some sort of overpowered jutsu or dark magic to gain control over all the characters. However, this would completely change the nature of the Naruto world. The relationships between characters like Sasuke, Sakura, and the rest of the ninja clans would be shattered, and instead of a world of cooperation, it would be a world of oppression.
It would be a very wrong interpretation of the characters. Naruto is a character who stands for justice and freedom, and enslaving someone is completely against his nature. Tsunade is a strong - willed and respected character too. Such a fanfic would distort their images.
I'm not sure if there is a specifically 'well - written' and appropriate fanfic with such a disturbing concept as 'naruto enslaves kushina'. This goes against the normal positive relationships in the Naruto universe. Fanfics usually explore positive character developments and relationships, so this kind of plot is quite abnormal and not likely to be common in high - quality fanfic works.
It could also be that the 'enslaves' part is not literal in the sense of physical slavery. Perhaps Naruto has some kind of mental hold over Kushina. For example, he might have discovered a way to manipulate her memories or emotions, which gives him a form of control. This would be a more psychological form of 'enslavement' and could lead to a complex and twisted plot.
I'm not sure if there is such a specific fanfic. Fanfic writers come up with all kinds of creative ideas, but this one seems rather unusual. It's possible that in some very niche or less - known corners of the fanfic world, it might exist, but I haven't come across it personally.
