Take a break. Sometimes stepping away from the story for a while can clear your mind. When you come back, you might see things more clearly.
Look at some similar stories for inspiration. See how other authors have dealt with similar situations in their plots or character development. It could give you some fresh ideas to move your story forward. You can also try freewriting. Just start writing whatever comes to your mind related to the story, even if it seems a bit random at first. Eventually, you might stumble upon an idea that gets you unstuck.
If she's stuck in a physical space like a small hole or a tight corner, she can try to wiggle her body slowly. Sometimes a little movement at a time can help her get free.
She could try to wiggle her way out gently. If it's just a matter of being a bit wedged, some careful movement might free her.
She can try to gently twist and turn her foot to loosen it from whatever it's stuck in.
Maybe someone pushed her from behind to get her through. Or pulled her from the other side.
Try using a thin object like a ruler or a wire to carefully push the manga out.
One way is to wait for the object his tongue is stuck to warm up a bit. If it's a metal pole, for example, as the surrounding air temperature rises or if the sun shines on it, it might gradually warm up and his tongue will come loose. Another option is to breathe warm air on it. He can cup his hands around his mouth and blow warm air towards his tongue. This might take some time but could work.
He might use his magic skills. For instance, he could use a spell to break whatever force is keeping him in the middle position.
You could try starting a new novel. Sometimes getting into a different story can shift your focus away from the one you're stuck on.
Another way would be to seek help from other characters within the story who have some sort of meta - knowledge. There might be an old wizard or a super - intelligent alien who understands the nature of the stories they're in. Spider - Man could team up with them to figure out a solution. They could try to disrupt the flow of the story, for example, by creating a paradox. If they can make the story's internal logic break down, it might free Spider - Man from being stuck in the story.
Ino herself could use her own skills. Since she's a ninja, she could try to fight her way out if she's physically trapped. If it's an emotional or mental block, she could have an epiphany through self - reflection. Ino might remember her training, her goals, and her relationships, and that could give her the strength and clarity to break free from the situation she's stuck in within the fanfic.
