Here's one from
Crossing Moon by Robert Haynie, wherein Ranma is the reborn Princess Serenity and reassumes Serenity's form and personality at Jusenkyo.
Usagi's first day at school proved to be interesting.
She had only attended general elementary schools and an all boys junior high (for a while in both cases) before, and so wasn't really familiar with high school ritual, but she felt fairly certain that they usually didn't start with a pack of some thirty to fifty boys in various sports outfits trying apparently to beat the living crap out of a girl while at the same time crying seemingly heartfelt protestations of love. She hadn't had a date yet-- ever-- boy or girl, but she was fairly certain that that wasn't the way it was usually gone about.
Then again, she was more interested in the somewhat familiar moves of the girl with longish black hair who was not trying to beat the living crap out of her suitors, but instead was succeeding in beating the living crap out of her suitors.
As the last of the mob fell, and the brunette stood panting, Usagi made a beeline for her, ignoring the arriving babble about teak and dying.
"Wow! I've seen multiple opponent techniques before, but that one was really good! I'm Usagi-- Usagi Saotome, I'm new at school, what's your name? Was that Anything Goes? I didn't think anyone but Pops and me did Anything Goes..."
"Truly, such a boorish-- excuse me, miss, I need to-- Pardon me, miss, but-- EXCUSE ME?"
The dark-haired girl stared at the sudden blonde face that had appeared in front of her that was saying something totally impossible. "A-Anything Goes?"
"But anyway, that was really good fighting! Although I don't see why y'were fighting, I mean, I thought I heard those guys yelling something about dating with ya if they beatcha, but that doesn't make sense, does it? So, was that some sort of demonstration, or--"
"Miss, I understand your enthusiasm for the fair Akane's skills--and indeed, I must admit to sharing them, for they are truly remarkable for a woman-- but 'tis now when I must issue my challenge for her hand, and--"
Usagi blinked. "Waitaminnit. He sayin' that all these guys WERE trying to beat you up to get a date with you?" she asked, dismissing the kendoist. "What, are you from some Amazon family or something?"
"Truly, she has the spirit of an Amazon of legend, but still, I must ask you to--"
"Did you say Anything Goes?" asked Dark-hair.
"Yup! And some of what you did looked like that, but it was mostly Kempo, and I'm really curious?"
Dark-hair blinked. A girl that could understand Kempo AND Anything Goes-- AND tell the difference-- at a glance. She HAD to get to know her.
"Well, my name's Akane Tendo. And we better hurry, or we'll be late for class."
"AW, geez! You're right, don't wanna be late on my first day!"
The two headed off to class leaving a sputtering and for once unbruised Tatewaki Kuno behind.
They got to class on time.
Kuno didn't. And he hated bucket duty.
*EDIT*
And another one.
Akane was beginning to think that trying to cheer Usagi-chan up wasn't a good idea.
Usagi was-- to be honest-- a tomboy. Well, if Akane was to be honest, so was she. But most Japanese girls wouldn't admit that to be true, where Usagi reveled in it. She was PROUD of being a tomboy.
But Usagi had been rather depressed about the test today. And, so, Akane had decided to get her friend a little present to cheer her up.
Now, Akane, tomboyish at times or not, was mostly a normal girl anyhow. Including her tastes in manga. Shojo all the way. Usagi, on the other hand, had a definite preference for shonen manga-- and would lament her lack of pocket money to collect the manga she liked.
It wasn't surprising. After all, her father had dragged her all over Japan and China in that training journey-- Usagi had only discovered manga recently, and being raised as a boy and all, would logically prefer the Shonen stuff... at least the kind about fighting.
Thus, Akane decided to get Usagi the DragonBall Z volume that she knew that the blonde hadn't been able to afford herself so far. This proved to be... a mistake.
Because the manga saleswoman wasn't-- a saleswoman.
Or, really, a woman at all.
Akane was a skilled Martial Artist-- she knew that. Not as good as Usagi, but still skilled.
At the moment, Martial Arts were oddly useless.
After all, monsters weren't bricks or perverts. And THIS was a monster. That had her by the throat.
"So much energy, so much. Oh, Master Jadeite WILL be pleased with me--"
"Let her go."
Akane, weakly, tried to see where the voice came from. Someone--someone trying to help her-- who...
"What?" the monster said, surprised.
"I said-- LET HER GO."
"And who are you to--"
"I am..." The newcomer paused, for a moment, uncertainly... and then regained her determination. "Agent of Love and Justice, I am the Pretty Sailor Suited Soldier Sailor Moon! Manga is for fun and relaxation, and your abuse of it is totally unforgivable! And in the name of the Moon--"
Here Sailor Moon struck a dynamic pose, pointing at the youma, and called--
"I ACCEPT YOUR CHALLENGE! Um. Hmmm. Maybe I should work on that bit."
