The plot could involve a rescue mission. Kaoru's friends or family might discover the kidnapping and start looking for her. They could face many obstacles on the way, like traps set by Okashira. And Kaoru herself could be trying to escape from where she's being held captive in the fanfiction.
Well, it could be that Okashira has some strange motives for kidnapping Kaoru. Maybe he's jealous of Kaoru's popularity or something else in the fictional world. He might be planning to use Kaoru to gain something, like information or power within the story's context.
There could also be other characters like Kaoru's friends. They would play an important role in trying to rescue her. For example, a very close friend who has some special skills, like being good at tracking or fighting, could be a key figure in the rescue attempt. And maybe there's an authority figure, like a detective or a wise old mentor who helps in the search.
One possible plot could be that a rival group of Kenshin's enemies kidnaps Kaoru to lure him into a trap. They might hold her in an old, abandoned building. Kenshin would then have to use his skills and enlist the help of his friends like Sanosuke to find her. The kidnappers could demand that Kenshin give up his sword in exchange for Kaoru's safety.
One possibility is that Kaoru's friends or allies will immediately start a rescue mission. They could track down Takeda Kanryu's hideout and try to free Kaoru through a fight or some clever plan.
One plot idea could be that the kidnapper has a personal vendetta against Kaoru. Maybe Kaoru witnessed something she shouldn't have, and the kidnapper wants to keep her quiet. Another idea is that it's a case of mistaken identity, and the real target was someone else in the same hospital. A third idea could be that a deranged fan of Kaoru's kidnaps her in an attempt to make her their own, thinking they can 'protect' her from the outside world.
Well, perhaps Aoshi kidnaps Kaoru because he believes she has some information crucial to his clan's honor. He might be acting out of a sense of duty that has been warped by his past traumas.
A plot might be set in a different time period, say a historical setting. Hikaru and Kaoru could be from two different social classes, but they meet secretly. Their relationship develops over time, and the kiss could be a symbol of their defiance against the social norms that try to keep them apart. It could also be a modern - day plot where they are dealing with the pressures of school and family, and their kiss is a moment of pure emotional release in the midst of all the chaos.
The idea of Kaoru being kidnapped by Takeda Kanryu in a fanfiction is quite interesting. It could lead to a lot of character development. For Kaoru, it might be a journey of self - discovery and finding strength in a difficult situation. Takeda Kanryu, on the other hand, might have his own backstory that led him to this extreme action. The fanfiction could also show how the relationship between these two characters changes over time, from enmity to perhaps something more complex like understanding or even a form of redemption.
It could be a jealous coworker. Maybe they feel that Kaoru is getting all the attention or a promotion they wanted. Another possibility is a patient who has become obsessed with Kaoru during their treatment. Or perhaps it's someone from Kaoru's past who has a grudge against her.
Well, it might be that the kidnapper has some sort of medical need that they think Kaoru can fulfill. Since she's a nurse, they could be desperate for medical attention that they can't get through legal means. Or perhaps there's a villain in the fanfiction who just wants to create chaos in the hospital by taking one of its nurses, and Kaoru happened to be the unlucky one.
In a more out - of - the - box plot, Matpat could be kidnapped by an interdimensional being that is offended by his theories about certain game universes. Matpat then has to convince the being that his theories are just speculation and try to find a way back to his own dimension, all while trying to understand the strange new world he's in which is filled with elements from different games he's analyzed.
