Nabiki in the time-loops.
Another loop outside of mainstream accepted opinion...
Nabiki angrily sipped her lemon juice while her father rambled on about the arranged marriage. This was the three hundred and thirteenth time she had to listen to that drivel and she was thoroughly sick of it.
Back during the first couple of loops, she had enjoyed having the knowledge of future events. Especially during the second loop, when even the experience of seeing the same things for a second time was a novelty. The thrill of subtle variations of the things she said and did and the reactions of others! Knowing how to best manipulate her dates and getting a reputation as the Ice Queen of Nerima! Wrestling control of the betting market with outrageous bets and wins! And ending the loop by presenting him with the bill for a destroyed dojo was the icing on the cake.
And those fantastic rumors during the first loops! "She has cameras in every corner of the house!" "She controls the Japanese underworld!" "A demon has sold its soul to her!"
Of course there were setbacks. The martial artist prince who took her for a bride. The local oyabun who sold her as a slave. The ghost who violated her soul.
But she got back at all of them easily by arranging them to meet the idiot before they became dangerous to her and while they lost she took what she wanted and more.
Still, those things were dangerous and she was aware there could be bigger threats that might be able to destroy her sanity, making her unable to get her revenge on them. Back then she had decided that her sharp intellect was her best weapon and the place to sharpen this weapon would be university.
Getting there was easy. She just had to spend the end of one loop to collect last year's tests, scandals and passwords and next loop she was the best-informed wunderkind freshman of the world's most prestigious universities.
The problem was leaving Nerima behind, or more specifically, Ranma. The bane of her existence. Wherever she went, the cursed aquatranssexual martial artist idiot savant would appear and fight someone else with a ridiculous fighting style, leaving her place of education in ruins.
Study at Tokyo University? Ranma would fight a martial artist lawyer leaving the whole campus under an avalanche of red tape and the dean deciding to close the place for the year that it took to clean the place.
Kyoto? A fight with a martial arts baker, crushing the university under a dough with simply too much yeast.
All of Fukuoka was flooded with fish after a fight with a martial arts angler.
There was always an explanation how the idiot had ended at her university. A training trip that he always made during the loops. Her sisters visiting her and he "had" to accompany them at the order of their parents. Another student hearing her name, deciding to challenge the dojo and Ranma came to win the return match.
Even when she ran away from home to study under an assumed name, he would find her place because of simple coincidences. The student whose place she took during the loop, the professors, the other students, her landlords, salesmen - they all talked to her and then met other people than they would have had in the original timeline and it always led to a chain reaction ending with Saotome fighting another idiot at her school and destroying it in the process.
The worst part was that the further away she got from Nerima, the worse the destruction became. She still had nightmares of Ranma fighting with that red-clad blond in Los Angeles with the - in hindsight - scarily fitting nickname "Human Typhoon," the master of martial arts surfing.
She hadn't dared going to study anywhere in Europe, because that place might have ended joining Atlantis at the bottom of the sea.
After Los Angeles she had decided to give up on getting a formal education, but then she had realized that would have meant she had lost against that idiot!
She tried Tokyo University again, but it took her all year to get the martial arts lawyer from its grounds. Strangely enough, Ranma didn't destroy the grounds that loop, but she was too busy with martial arts rules lawyering to learn anything useful.
The next loop she needed one hour, but the following day the other students of the Law Dojo declared martial law and tried to find the next master of the school with an all-out brawl. Ranma intervened and once again the semester ended prematurely when the campus was covered knee deep in legal documents and was declared a fire hazard.
Evicting the Law Dojo in the next loop led to rival dojos invading and Ranma "helping" the innocent bystanders with now predictable results.
Trying the same in Kyoto had similar results. She didn't try Fukuoka. She still hated fish.
Directly starting a career was only a variation of the theme. She would blackmail her way to the top and stay there - sometimes her subordinates even respected her intellect - but it always ended when one of Ranma's fights got close to her business.
Those things couldn't be coincidences and they had only one thing in common. Ranma Saotome. He always acted innocent and he never reacted when she mentioned something from older loops or things that he shouldn't know yet. She still could manipulate him into all kinds of embarrassing, humiliating and disgusting situations. But that had to be an act, he was playing the fool to trick her for his own amusement. Because at the end of every loop she was sitting in her room in the Tendo home with nothing more than a growing sense of frustration.
Returning to the present, she grinded her teeth. There was only one solution. The trickster god known as Ranma Saotome had to be killed!
Now she only had to find out how to destroy gods...
Just for variety, a fic where the Awakened character isn't able to control everybody with foreknowledge and the butterfly effect is in full swing.
There is of course a simple explanation why this is happening to Nabiki. She had once stepped on the avatar of the gods of butterflies and now he is using his powers to get his vengeance. :D
