This fanfic might start with Naruto feeling exhausted from his regular ninja training. As he lies down to take a nap, his mind wanders into a world where he's a swordsman using Santoryu. He might face off against some new enemies in his dream, enemies that can only be defeated with the unique slashing and stabbing moves of Santoryu. And when he wakes up, he might find that some of the skills or the understanding of balance and movement from the Santoryu in his dream have seeped into his real - life ninja abilities.
Perhaps Naruto has a strange encounter right before his nap. He meets someone who gives him a brief introduction to Santoryu. Then, during the nap, his subconscious takes over and he starts to practice the moves. He might be in a dojo - like dream setting, sparring with imaginary opponents using Santoryu.
The combination of two different universes makes it interesting. Naruto's world is full of ninjas and chakra, while santoryu comes from One Piece's swashbuckling world. When they mix in 'naruto santoryu fanfic', it creates unique and unexpected storylines.
There are quite a few 'naruto santoryu fanfic' out there. 'Naruto's Santoryu Evolution' is a notable one. In it, Naruto starts with basic santoryu skills and gradually evolves them into a more powerful form. The story also delves into how his friends and the village react to this new ability of his. Additionally, 'Santoryu in the Naruto World' explores the implications of having a santoryu - style fighter in the Naruto universe, like how it affects the existing power balance and relationships.
The charm lies in the way it shows a moment of rest and relaxation. It makes us feel like we can relate to that need for a break. Also, the artistic style and expressions of the girl can add to the appeal.
Ruby is a likely candidate. She's already a skilled fighter with her scythe, and her eagerness to learn new techniques would make her adapt well to Santoryu. Her speed and agility could be enhanced with the three - sword style.
In a fanfic of Kisame and Itachi taking Naruto, it might explore the relationship between the two Akatsuki members and Naruto. Itachi has his own complex reasons for his actions, and Kisame is his loyal partner. When they take Naruto, Itachi might be conflicted as he has a connection to Naruto through Sasuke. They could end up in a situation where they have to make a choice about what to do with Naruto.
One interesting aspect could be the unique combination of the Santoryu style from One Piece with the RWBY universe. It might lead to really cool fight scenes where characters use Santoryu techniques in the RWBY world. For example, seeing Ruby use a Santoryu - inspired sword style would be amazing.
