Sakura might have some hidden jutsu up her sleeve. Maybe she has been secretly training a new form of chakra control that can allow her to phase through solid objects like Susanoo. Or she could use her superhuman strength to find a weak point in Susanoo's structure and break out.
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.
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.
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.
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 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.
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.
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.
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.
Sasuke's Susanoo in the manga is depicted as a powerful and imposing force. It has unique features and abilities that make it a significant asset in battles.
Well, it's not really ethical. Sasuke should be more upfront and find other ways to escape rather than using Sakura like that. Sakura trusts Sasuke and for him to seduce her just for his own gain, like escaping, is wrong. Fanfiction might play with these concepts in different ways, but overall it's a behavior that doesn't sit right. It also doesn't fit well with Sasuke's character development in the original story where he is trying to become more than just a self - centered person.
Sakura might have a hidden jutsu or power that she has not yet fully explored. In this dire situation, she could tap into this unknown ability to break free from the snakes. For example, she could have some latent chakra - based power that she discovers can repel or dissolve the snakes binding her.
