One characteristic is often the presence of violence. For example, in 'Berserk', there are intense battle scenes with a lot of bloodshed. Another characteristic can be mature themes such as sexuality. Some anime might touch on complex relationships and adult - oriented topics. Also, strong language can be part of it in some cases, though not as common as in live - action rated R works.
One interesting storyline could be Sakura going on missions with multiple characters from different villages. For example, she teams up with Rock Lee and Gaara to stop a new threat that endangers all the ninja villages. Their different fighting styles and personalities create a lot of drama and action.
Well, I really like the 'r naruto fanfic' called 'Naruto's Ascent'. In this fanfic, Naruto has to overcome some really difficult challenges that are different from the original story. It makes for an exciting read. Also, 'The Sage's Apprentice' is a cool one. Here, Naruto gets trained by an ancient sage in a very different way compared to Jiraiya. And 'Friendship Forged in Fire' shows how Naruto and his friends' relationships are strengthened through some intense situations.
R-15 was a manga created by the Japanese manga artist Amagatsu, while the Lost Housekeeper was a light novel. There were some works that were adapted from light novels into anime, such as Evil Crown, About My Reincarnation as a Slime, Sword Art Domain, and so on. These works usually had excellent storylines and characters that were loved by the audience. However, due to copyright and review, the animation process of these works may be more complicated.
Kakashi can also be part of the'multi' in fanfictions. As Sakura's teacher, there could be stories where Kakashi takes Sakura on special solo missions, and during these missions, their relationship deepens beyond just a student - teacher bond, perhaps leading to a more complex emotional connection.
Anime like 'Ghost in the Shell' often contains mature themes that might be considered in the realm of 'rated R' for anime. It has complex philosophical ideas, some violence, and nudity in certain versions. However, it's also a very thought - provoking work that delves into questions of identity in a cybernetic future.
I recommend the book " Haruno Sakura: The Ninja Monogatari " to you. The main character is also Haruno Sakura, and she also transmigrated in the Naruto world, with a pay-to-win mobile game system. After obtaining all kinds of ninja character cards, Sakura also fell into the path of no return. Then, on her journey to the top of the world, she realized that the world seemed to have changed. I hope you will like this novel.
On Naruto's side, he would probably feel guilty after realizing what he had done. This guilt could make him try to make amends, but Sakura's initial reaction of anger and hurt would still be a big obstacle in their relationship. Their interactions would be filled with tension and awkwardness.
In proper fanfics rather than 'lemon' ones (as 'lemon' implies inappropriate content), Naruto is known for his never - give - up attitude. He's the heart of the story, always trying to bring Sasuke back and protect his friends. Sasuke is a complex character, with his family's past haunting him, which makes him seek power and revenge at times. Sakura, she starts as a girl with a crush but evolves into a capable ninja. These characteristics are often the foundation for fanfic authors to create interesting stories that don't involve improper content.
It could be Sasuke. If Sasuke has some sort of newfound connection with Naruto and it causes Naruto to shift his focus away from Sakura, then Sasuke would be the cause. For example, if Sasuke and Naruto team up for a powerful mission and their bond deepens in a way that makes Naruto neglect his relationship with Sakura.
