I got an urge to try a Ranma / Sailor Moon crossover
after visiting the now-infamous clich‚ crossover
generator site.  I tried a few generations, and found
myself facing a combination of rolls which just called to
me.
    Maybe my evil twin clone got inspired.
    So...

    Ami Mizuno, plucky Sailor Mercury, daughter of the
hard-working and widely-liked but somewhat dotty Doctor
Nodoka Mizuno, and all-around girl genius, sighed
disconsolately as she sat at her desk.  A textbook sat
upon her desk, ignored in preference for a photograph
which she held in her hands.
    It showed herself and her friends Minako, Rei,
Makoto, and Usagi standing in front of a Ferris wheel.
She was smiling happily, Minako was grinning and making a
"V" sign at the camera, Makoto had her arms crossed and
was smiling smugly, while Usagi... Usagi hung off the
neck of her boyfriend, Mamoru.
    `Usagi's so lucky...' she mused to herself.
    With another wistful sigh, Ami replaced the framed
photograph on the shelf above her desk and turned to look
out her window for a long moment before returning her
attention to her textbook.
    Her hopes for further study were interrupted by the
loud closing of the front door.  "I'm home, Ami!" came
her mother's voice, and with a smile Ami pushed herself
back from the desk and stood to go and greet her mother.
    
    Nodoka Mizuno, stepping into the main living room of
their apartment after doffing her shoes in the small
genkan immediately by the front door, smiled tiredly as
her daughter entered the living room.  "Ami, dear, how
was your day?"
    Ami returned her mother's smile.  "It was fine,
mother, a pretty normal day.  Oh, I went out with Usagi-
chan, Mina-chan, and Mako-chan to the arcade for a little
while after school, so I haven't finished my homework
yet."
    Nodoka stepped over to Ami and gave her a maternal
hug.  "That's lovely, dear.  You study so hard, it's
wonderful that you spend some time with your friends as
well."  Breaking the embrace, she stepped over to the
small side table near the door which was bare save a
small stack of letters and brochures.  "Is this today's
mail?"
    "Yes.  There's a letter from someone."  Interest
tinged her voice.
    "Thank you, dear."  Nodoka picked up the small pile
of letters, leaving the three advertising flyers sitting
on the table.  The first two letters were a bank
statement and the bi-monthly power bill, but the third
was beautifully calligraphed, the envelope appearing
skilfully hand-made.  She could see why it would have
attracted Ami's attention.
    "Whatever could this be?" she mused under her breath
as she tore open the flap at the narrow end of the
envelope and drew out the stiff pages enclosed therein.
Ami watched her curiously, then darted over in alarm as
paper fell from her mother's suddenly-nerveless fingers
and she seemed ready to collapse.  A huge grin lit up
Nodoka's face as she turned Ami's gesture of support into
an ecstatic embrace.
    "What is it, mother?"
    "Ranma's coming home," she breathed ecstatically.
"Ranma!  Oh, my son, you're coming home!"
    Ami stared at Nodoka, aghast.  "R-ranma?  I have a
*brother*?"

    Dear Mother,
    I write with happy news.  My training here is
finished and my master has suggested that I should spend
some time with my family.  He said I should become used
to the company of those of my own age as well as gaining
experience to temper the knowledge I have gained under
him.
    I will therefore be returning home as soon as
possible.  I expect to arrive mid-afternoon on Saturday
the fourteenth.  I very much look forward to seeing you,
and hope that after all these years I am welcome in your
home.
    I have much to tell you.
    Your dutiful son,
                 Ranma.

    "What's wrong, Ami-chan?  You've been out of it all
morning."
    Ami started as she was jerked out of her speculation
by the touch of Usagi's hand on her shoulder.  It was the
end of second class, and the teacher had left the
classroom while Ami was distracted.  Students started
chatting, some moving around as they waited for the next
teacher to arrive, while outside the sun shone invitingly
from a sky streaked with high, wispy cirrus clouds.
    "Oh, Usagi-chan, I'm sorry," said Ami as she
concentrated on the here and now.  "What did you want?"
    "What's up?" repeated Usagi.  "It's not like you to
not pay attention in class?"
    "I..."  Ami looked around at their fellow students.
"Can we talk about this at lunch, Usagi-chan?  It's a
long story."
    "Sure!  But don't worry, Ami-chan!  I'm sure it'll
work out fine, whatever it is."
    "Oh, it's nothing bad, Usagi-chan," said Ami.  She
frantically waved her hands in denial, fending off the
waves of sympathy coming from her friend.  "It's just
that after all these years, Mother finally tells me that
I've got a brother coming."
    "Ohh, what wonderful news!  Who's the father?  When
will he be born?  Will she be getting married?  Do you
like your new step-father?"
    Ami blushed furiously as she noticed that she was
suddenly the centre of attention of the classroom.
"Mother says he's about my age," she protested.  "I've
never met him.  I didn't even know he existed until last
night!"
    "Oh, how *radical*," commented one girl from the back
of the ring which now surrounded Ami and Usagi.
    "Yes, how free-spirited your mother must be," said
another.
    Ami's blush turned hot pink as she frantically
flapped her hands.  "No, no, my *brother*!  My *brother*
is about my age!"
    There was a pause, a kind of disappointed quiet.
Then...
    "Wow, will he be coming here?"  "Is he good-looking?"
"Do you think you could introduce me, Ami-chan?"  "Cool,
I wonder if he's a stud?"
    Blushing strawberry pink once more, Ami buried her
head in her hands and shook her head ruefully as she
noted Usagi leading the charge of enthusiastic questions.
Having friends was not, it seemed, an unalloyed pleasure.
Still, despite wishing with all her heart that the
teacher for the next lesson would walk in the door and
rescue her, she could not help but smile at Usagi's
antics.

    The clock on the wall ticked loudly as Ami sat in the
living room of the apartment she shared with her mother.
She was unquiet, shifting nervously even as she attempted
to distract herself with a good book on recent research
into astrophysics.
    Nearby, her mother knelt on a large cushion on the
floor.  She looked very much as though she wanted to be
in her best kimono and obi, but instead she wore her
working clothes - a sharply-pressed skirt of modest
length and a comfortable white long-sleeved blouse.  She
would have to leave shortly to get to the hospital on
time to begin her shift, and Ami was beginning to worry
that Ranma would not arrive in time before Nodoka had to
leave.
    *BZZZT!*
    The doorbell was shockingly loud, and Ami found
herself jerking to her feet in anticipation.  Still, she
was slow compared to Nodoka, who appeared to teleport to
the door.  With a twist and a heave, she flung it open.
    A boy stood there, dressed in an ebony high-collared
suit which resembled a school uniform in a number of ways
except that it appeared to be made from raw silk.
Against that dark background, this somewhat tanned skin
of his face and hands stood out in stark comparison,
framed by long but fairly normal black hair pulled back
into ponytail.
    He stood stock still, just staring at Nodoka, and
finally it was Nodoka who broke the silence.  "R-ranma?
Is that you, my son?"
    "Mother?"
    Nodoka glomped an amazed. Ranma, dragging him inside.
"Oh, Ranma!  It's been so long, it's been so long."
    Hesitantly, Ranma returned the embrace.  Ami saw a
smile grow on his lips.
    "Oh, Ranma, oh, Ranma," she repeated.
    "Mother, it's so nice to be home."
    After another long moment, Nodoka broke the embrace
and gestured to Ami.  "Ranma, this is your sister Ami.
You would not remember her; I adopted her after her
parents were killed when she was seven.  She's sixteen
now, the same age as you."
    Ami bowed at Ranma, and was pleased to see him bow
formally to her in reply.  "How do you do.  A pleasure do
meet you," she said, mouthing the ritual phrases of
meeting.
