She was pretty familiar with the usual One Piece self-insert story rules. Some unsuspecting, but strangely competent fan manages to catch the attention of some R.O. B., who was usually an asshole, and went off to have adventures with the Strawhats. The character managed to help save the day and help improve the story, while befriending everyone.
She did not get some nice warning from a R.O.B.. And really why would all these omnipotent beings be spending their time fulfilling fannish wishes anyway?
She woke up to someone pressing down on her chest with enough force to break bones and what felt like a gallon of saltwater forcing its way up her throat.
She woke shaking and feeling like she had been dragged through a sander, her throat burning and her voice gone.
She woke wet and terrified and almost having died. Almost having drowned, of all the nonsensical ways, with strangers all around her dressed in identical white and blue uniforms.
She had no warning. No explanation. And no magical assistance or even mocking note to explain her waking up on a strange naval boat manned by the oddest marines she had ever met.
She spent days alternating between terror and illness as she quickly grew seasick on the rocking boat.
She had to spend the following weeks learning the language everyone spoke that sounded vaguely like Japanese at times.
She had to spend months earning her keep by breaking her skin cleaning, pricking herself as she learned how to sew, and pissing off the cook by stumbling her way through being his assistant.
She almost died when said cook smacked her on the head at full strength and gave her a concussion, knocking her out before she learned everyone else, even the weakest chore boy, was seemingly a hundred times more durable than her.
She had to find out that pirate were a thing when the ship was surprised during the night and she was useless, her best punch having seemingly no effect when she was surprised and dragged into being a hostage.
She had to deal with the horrifying feeling of blood and brain matter splattering on her face when one of the kinder men, a sharpshooter, took out the pirate who was holding her hostage and traumatized her in the process.
She had to deal with the return of old nightmares blending in with new ones as the gunshot took her back to another one and the blood on her face changed from the pirate's to her mother's.
She had to realize, at long last, where she was when she came down with a fever, unable to take the constant weather changes.
She had to face this discovery as her heart failed twice and she hallucinated, horrible images from her past and nightmares alike.
She had to hear the phrase "Grand Line" in startlingly clear English, as the sad-eyed doctor shook his head at the younger officers, who had gotten friendly with her despite the language barrier and began to see her as some kind of ship mascot.
She had no hope of finding the Straw Hats in the bosom of the navy and no desire for more adventure.
She fought tooth and claw through her illness and this and the scars from her work, despite her "delicacy" earned her the affection and respect of the men she traveled with.
She found herself at Marineford with promises of "taking her back home", made by Commodore Green with a friendly pat on her shoulder and invitation to stay with his family in the surrounding town, while he took care of business.
She learned that her explanation of being from "Eastern United States" had been misunderstood as being from the East Blue.
She remembered how devastated the East Blue became by dangers and how dangerous this world was in general. How corrupt and horrible.
She remembered the island of Ohara, Flevance, the Gray Terminal, Dressrosa, Alabasta.
She had realized she was weak and on top of that a coward. She would be a poor protagonist.
She convinced the Commodore to get her a job at Marineford.
She became a janitor, twenty years before One Piece was due to begin.
