A 32 year old Ranma lay atop of his roof, staring up at the star filled sky, thinking back to the 'good' old days when he was engaged to four girls and had an endless list of rivals attacking him at every turn, life had been interesting back then. However, now it was boring, all his rivals had been beaten and had found someone else to be with or bother, his fiancé's had met other people, well except for one who stayed with him and married him, even though his curse still plagued him life was boring, he had obtained complete control over it and could switch between the two forms with mere will with or without water, even if it still acted as a trigger.
Ranma then leapt down to the ground and headed to the she in the garden, where he kept books and scrolls that listed several techniques and all the ways to master them, when he entered he sat at his desk and turned on his old lamp that shone dimly, Ranma then proceeded to pull the book Shampoo had sent him last Christmas, he opened it and began to read the Chinese texts, he had picked it up when he visited Shampoo, he noticed one text that caught his eye, it said it was a technique that was used to change fate and allowed the user to move through time when used correctly, Ranma then thought back to earlier that day when he'd almost completely destroyed the dojo during his training. "maybe this will allow me to stop it from happening" Ranma thought allowed before looking at the instructions and mimicked them perfectly, following every step, but stopped when he noticed the corner of the page had been ripped away and half the last step was missing, however, Ranma had already performed enough of the technique for it to work, sending Ranma through time, however, since he hadn't completed the final step it would send him to a random part in his time stream, past or future.
Ranma then found himself in the park, in the middle of the night, Ranma then thought back to what the book had said 'this technique sends the user though time to the point they chose including that destination' "something went wrong, this doesn't look like the dojo so the question is where and when am I?" Ranma thought allowed before heading down the street, he began to recognise the place as Nerima, however, at which point of his life was he in. Ranma then noticed a sign which read 'Tendo Dojo' Ranma then smirked before entering the place, he looked at the koi pond to his left, he always hated that pond when he was younger, he'd always some how end up in it. Ranma then noticed a bedroom light on, one he recognised as Akane, he then leapt up on to the trees branch and used the 'now you see me now you don't ' technique. He saw Akane in her usual pyjamas, holding P-Chan to her chest, Ranma paid close attention to her face "lets see, judging by her height and appearance that would range her from 16 to 19 and the fact she thinks Ryoga is her pet pig puts her between 16 and 17" Ranma muttered to himself, trying to figure out what year it was.
The next day…
Ranma awoke in the same tree and looked down to see his younger self running with Akane, in a rush to get to school. Ranma then leapt down and began to enter the Tendo residence, knowing all the adolescents would be at school, making it easier for him, he then noticed out of the corner of his eye the old freak heading off to the school as well 'with the freak here that narrows it down even more' Ranma thought to himself.
"Yes, may I help you?" Kasumi asked as she noticed Ranma, she was slightly wide eyed with the fact that he had black hair in a pigtail and looked identical to Ranma, just older in dark jeans and a black vest.
"Hi Kasumi is the panda and Soun out of bed yet?" Ranma asked as he slouched.
"How did you know my name?" Kasumi asked surprised.
"You should know that one Kasumi" Ranma replied with an all knowing tone and Kasumi's eyes narrowed.
"Ranma from the future" she replied.
"yep and I know all about you, in order to protect your siblings from the genetic disease that took your mother from you, you made a deal with the devil who made you a demon in return for saving them" Ranma replied.
"what do you want" Kasumi asked coldly.
"tell me how far I've gone back" Ranma replied.
"judging by your aura I'd say 16 years and 3 months" she replied in her usual sweet tone.
"just great, well things will certainly be more interesting now huh" Ranma sighed
