Sakura could struggle against the Susanoo hand at first, thinking Sasuke is trying to harm her. But once she realizes his intention, she could use her chakra to enhance the Susanoo's power. They could then combine their forces and launch a counter - attack against their opponents.
One possible scenario in this fanfiction could be that Sasuke's Susanoo hand captures Sakura in a moment of intense battle. Maybe it's not an act of aggression but rather an attempt to protect her from an unseen enemy. The Susanoo's power is so great that when it reaches out to grab Sakura, it creates a sense of both danger and safety at the same time. She might initially be startled but then realizes Sasuke's intention.
In this fanfiction, it might be that Sakura is physically restrained within Sasuke's Susanoo hand. She could be struggling against the power of the Susanoo itself, like it's draining her energy or causing her pain. And she has to find a way to either escape or get Sasuke to release her on his own.
She could try to appeal to Sasuke's emotions. If she can remind him of their past, of the times they fought together and cared for each other, it might make him release her. Sakura could talk about their shared experiences and how they are on the same side deep down, hoping to break through whatever is making Sasuke hold her captive.
She might develop more resilience. Struggling in Sasuke's Susanoo hand would surely test her limits. She could become more self - reliant as she tries to free herself.
There could be a fanfiction where Sasuke grabs Sakura with Susanoo during a chaotic event like a village - wide attack. The Susanoo's large form is able to cut through the chaos and reach Sakura just in time. Afterward, they have to work together to fend off the attackers. This shared experience could strengthen their relationship and make them more open to each other about their feelings and intentions.
One possible fanfiction could be about Sasuke using his Susanoo to save Sakura from a dangerous enemy. In this scenario, Sasuke, seeing Sakura in peril, quickly activates his Susanoo. The powerful, spectral form of the Susanoo reaches out with its massive hand and grabs Sakura, pulling her to safety. This moment could be a turning point in their relationship, with Sakura realizing anew how much Sasuke still cares for her, despite their past differences.
One possible reason could be that Sasuke is being influenced by some dark force. Maybe it has corrupted his mind and made him see Sakura as a threat to his new goals, whatever those might be in this fanfiction's plot. So, he uses Susanoo to hold her captive as a way to neutralize that threat.
There could be a story where an old enemy of Sasuke resurfaces. This time, the threat is not just to Sasuke but also to Sakura and Sarada. They have to work together as a family to defend themselves. Sasuke uses his combat skills, Sakura her medical ninjutsu and Sarada combines what she has learned from both parents. It's a story of family unity in the face of danger.
It's possible that they could play some simple games during the sleepover. Since they are shinobi, they might even have some friendly competitions related to their ninja skills, but in a very light - hearted way, like seeing who can do a simple jutsu faster without using too much chakra.
One possibility is that the story could focus on the emotional journey of the characters. For example, if Sakura is pregnant, she might be worried about how her friends and the village will react. Naruto could be there to support her, offering his positive energy and friendship. Sasuke might be more reserved in his support but still be there in his own way.
