Well, there are several factors. Firstly, a monotonous environment with no variety or novelty can do it. Secondly, if she has no goals or passions to pursue, it can lead to boredom-induced insanity. Also, a lack of intellectual stimulation might play a role.
A sexy insane woman in a story might have a strong sense of self - confidence that borders on overconfidence. Her sexiness gives her the feeling that she can get away with anything, and her insanity makes her believe she is always right. She could also be highly impulsive. If she sees something she wants, she'll go for it immediately, whether it's a shiny object or a person she fancies. Additionally, she might have a disregard for social norms. She won't care if it's proper or not to do something, like sitting on a park bench and singing at the top of her lungs in the middle of the day.
A sexy insane woman, Stella, lived in an old mansion on the outskirts of the village. She dressed in the most flamboyant clothes, always wearing bright red lipstick that made her look both alluring and a bit crazy. Stella believed she could talk to the spirits that haunted her mansion. She would often hold seances in her parlor, inviting all the curious villagers.

They might use underhanded tactics, like threatening to kill captives or using mind - control techniques on Naruto's friends. All of these things could make Naruto go insane as he battles against them, trying to protect what he loves.
One of my friends was bored waiting at the airport. So, he started to walk around in a really strange way, like he was a robot. People were looking at him but he didn't care. He said it made the long wait much more interesting.
The setting can also drive the plot. A harsh or unique environment forces characters to act in certain ways. Consider 'The Call of the Wild'. The Yukon during the Klondike Gold Rush is a brutal setting. Buck, the main character, has to adapt to this environment, which includes facing other dogs, harsh weather, and difficult tasks. These challenges based on the setting drive the plot as he evolves from a domesticated dog to a wild one.
Characters' goals and conflicts often drive the plot. Their desires, obstacles, and the choices they make shape the course of the story.
