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.
The plot could also involve Sakura's struggle as a symbol of her relationship with Sasuke. The Susanoo hand might represent Sasuke's over - protective or possessive side. Sakura is strong - willed, so she struggles against this confinement, both physically and metaphorically, as she tries to assert her own identity and agency within their relationship.
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.
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.
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.
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.
In this fanfiction, it could be that the 'curse' has given Sasuke some sort of power over Sakura. Sakura, being the strong - willed character she is, struggles against this new - found power dynamic. She may try to use her medical ninjutsu skills or her own chakra to counter the curse's effects while trying to free herself from Sasuke's grip, which might be strengthened by the curse.
I'm not sure specifically as there could be many different interpretations. It might involve Sakura facing some kind of difficult situation while in Sasuke's presence or under his influence.
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 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.
Perhaps the fanfiction focuses on Sakura's mental struggle as well. While in Kidomaru's arms, she might be thinking about her friends, her training, and how she can outwit him. She could be recalling all the jutsu she has learned and strategizing on how to turn the situation around. For example, if she has some knowledge of Kidomaru's weaknesses from previous battles or intel, she could be planning to use that to her advantage while still in his grasp.
