Well, in a fanfic, it could go either way depending on how the author writes it. If the author wants to emphasize the uniqueness of Sakuya's powers, she could be made to win. For example, she could use her time - stopping to set up a series of knife attacks that Naruto can't avoid. On the other hand, if the focus is on Naruto's growth and his never - give - up attitude, he could find a way to overcome Sakuya. Maybe he discovers a new form of chakra that can nullify her time - stopping ability.
The plot could involve Sakuya Izayoi using her time - stopping abilities against Naruto's ninjutsu. Maybe she tries to stop Naruto in his tracks during a fight, but Naruto uses his shadow clones to outwit her. Since Naruto is known for his determination, he might find a way to break through Sakuya's time - based powers and force her to face him in a more straightforward battle.
Often, these fanfics are set in fantastical settings. Since they both come from a rather otherworldly background, the fanfic authors can create amazing landscapes and magical elements for them to interact with. For example, there could be a fanfic where they are in a floating island filled with strange creatures and they have to work together to survive.
It's completely unacceptable. Such content not only goes against the general principles of a healthy and positive fan community but may also cause discomfort or harm to other fans, especially those who are minors or have no interest in sexualized interpretations of the character.
One key battle could be Naruto vs Itachi. Itachi is a very powerful Akatsuki member and Naruto has his own strong powers. Another might be Kakashi against Kisame. Kakashi is a skilled Konoha ninja and Kisame is a formidable Akatsuki member. Also, the fight between the Hokage of Konoha and the leader of Akatsuki would be crucial.
In many Servamp Mahiru x Sakuya fanfics, the theme of redemption can be present. If Sakuya has done something wrong in the original story, the fanfic might explore his path to redemption through his relationship with Mahiru. Also, the theme of power and its control can be explored. As Servamps are related to powers, how they handle their powers in relation to each other and their relationship is something that often appears in fanfics. Another theme could be the idea of family, as the Servamp world has a complex view of relationships that can be related to the concept of family.
One common theme could be a power - dynamic exploration. Given Dio's over - powering nature in Jojo and Sakuya's abilities in Touhou, how they interact in terms of power is interesting.
You can focus on her personality traits. For example, if she is brave in the original work, you can write about her new adventures that show her courage even more.
