Episode One:  The Twins

Soun Tendo walked out from his house with a backpack on his 
shoulder while his three daughters accompanied him to the front 
gate.  The youngest, Akane, looked at him with a mixture of doubt 
and worry; he smiled back at her to reassure her that everything 
would be all right.  She did not look convinced.

He felt that everything would be good hands with Kasumi in charge; 
she had certainly grown up and taken charge of the household duties 
when his wife died.  She was 19 now, and he had begun to worry 
about her finding a husband.  Maybe it was time to arrange one.  He 
hugged her and said "Don't worry, I'll be back in a week, and Mrs. 
Saotome will be coming here.  Take good care of the house."

He hugged Nabiki next, the package of snacks crackled as they were 
squashed when her hands met behind his neck.  He supposed that he 
ought to be worried that she seemed to be eating all the time, but she 
never seemed to gain any weight.  He thought to himself "Ah well, 
she's only 17, she must still be a growing girl.  Maybe this is just a 
phase."  He wondered briefly where she was getting the money from 
as he didn't think that her allowance was quite that large.

He hugged Akane last.  She had been indignant when he told her 
that she and Ranma were engaged.  She had given all her objections; 
that she was only 16, that she didn't know him at all, that she wasn't 
ready for such a relationship, and so on.  Eventually, Kasumi 
convinced her to at least meet him, reminding her that they had 
already met previously though they hadn't seen each other for at 
least five years.  Since mother's death, really.

Kasumi had borne up well at the funeral, but Nabiki and Akane had 
cried and held on tightly to Ranko and Ranma.  If Genma had taken 
them on a long training trip at that time, Soun wouldn't have known 
how the family would have coped.  Soun said "I'm sure that Ranma's 
a fine person, Akane.  I don't think you'll have anything to worry 
about." and started to walk down the street.

Soun waved as he turned the corner and the three sisters waved 
back.  He looked forward to seeing his old friends, Genma and 
Nodoka, and their twins, Ranma and Ranko for the first time in 
years.

***************

According to the address on the postcard, Soun was almost at 
Genma's house.  According to the deal that they had made with 
Nodoka when she found out about the engagement, Nodoka would 
present Ranma to Akane while the two of them "butt-ed out" for a 
week.  He stopped outside a small house with the right address and 
was promptly run over by a girl and a panda throwing water 
balloons at another girl.

Voice:  "Genma!  Ranma!  Ranko!  Stop fooling around.  Soun will 
        be here any time now."

The three of them stopped moving.  Unfortunately, the panda 
stopped right on top of Soun.  Nodoka stepped out of the house and 
saw the four of them in the street.  She quickly got Genma off the 
unconscious body and attempted to revive him.

Genma:  "Growf"  [Sign:  I thought the road was just bumpy.]

After a minute or so Soun regained consciousness.

Nodoka:  [reintroducing her children]  "This is Ranko,"  [pointing to 
        a young girl with red hair tied in the back with a pigtail, 
        with green eyes] "and this is Ranma." [indicating a young 
        girl with red hair tied in the back with a pigtail, with blue 
        eyes]

Soun blurted out "Ran... ma?" and fainted again.

***************

Soun woke in the Saotomes' living room.  Nodoka and Ranko were 
applying some smelling salts while Genma looked down at his old 
friend.

Soun:  "Saotome!  Now our families will never be united.  How 
        could you let Ranma have a sex change operation?"
Nodoka: [looking grimly at Genma] "It wasn't a sex change 
        operation.  My stupid husband," [Genma flinched] "took 
        them to this place in China and got them all cursed.  They 
        all change forms when they get wet.  Here, I'll show you."

Nodoka lined the three up and filled a bucket of water.

Ranma:  "I hate this."
Ranko:  "At least your clothes doesn't become too small and chokes 
        you."
Genma:  "Shut up, both of you."

Nodoka throws the water on the three leaving a red-haired blue-eyed 
girl, a black-haired green-eyed boy, and a panda.

Soun fainted again.

Ranko:  "Gee pop, he sure faints easy for a martial artist."

***************

Nodoka left the house with Ranma and Ranko behind her.  She 
reminded them (with katana out) that if they came anywhere near 
the house in the next week, she would kill them.  They then 
gathered their things, and the three of them left.

Soun:  "She's not really serious, is she, Saotome?"
Genma:  "I'm afraid so, Tendo.  I'm afraid so."

***************

Ranma:  "Mom, you're not really going to make me marry Akane, 
        are you?"
Nodoka:  "What's wrong, Ranma?  Don't you like her?"
Ranma:  "I don't know, mom!  The last time I saw her was at her 
        mother's funeral, and that was five years ago!  I don't think 
        its fair to engage me to someone I don't even know if I'll 
        like after all that time."
Nodoka:  "I know, Ranma.  When Akane's mother and I found out 
        that your fathers had made the engagement, we agreed to a 
        compromise.  When the both of you were sixteen, I'd bring 
        you over for a week without either father interfering, and 
        the two of you could decide whether or not to let the 
        engagement stand.  I also think that it wouldn't do you any 
        harm to at least meet her again."
Ranma:  "I guess."
Nodoka:  "And don't forget, she probably feels the same way about 
        you."

The three of them walked in silence for awhile.

Ranko:  "Why am I going, mom?"
Nodoka:  "There are some other things I need to discuss with the 
        both of you and the Tendo sisters.  Besides, if I left you at 
        home those two would probably decide to engage you to 
        either Nabiki or Kasumi."
Ranko:  "What other things?"
Nodoka:  "I'll explain when we get there."
Ranko:  "Why did we pack out things?"
Nodoka:  "Because even if the engagement is broken off, we'll be 
        moving in with the Tendos and taking over some of the 
        dojo's classes."

***************

Kasumi met the three Saotomes at the front door and showed them 
to what would be their rooms (Nodoka and Genma in one room, 
Ranma and Ranko in another) and told them that Nabiki and Akane 
should be home from school within the hour.  Kasumi started back 
downstairs as Nodoka informed the two that they would be attending 
school from tomorrow.  Her two children groaned.

Nodoka grinned at Kasumi's descending back, then entered her own 
room and started to unpack her things.

***************

Akane and Nabiki came home and everyone was introduced.  While 
Kasumi started preparing dinner (after refusing Nodoka's offer to 
help) Nabiki related what had happened during the intervening 
years since the Saotomes' last visit.  Everyone noticed the way 
Ranma and Akane seemed to look at each other appraisingly.

Dinner went by fast and Nodoka explained to Akane that at the end 
of the week, either she or Ranma can break off the engagement if 
they want to.  Kasumi cleared the table and Nodoka said she had 
something important to show Akane.  Ranma looked at his mother 
with eyes that said "Do we have to?".  Nodoka just nodded "yes" and 
poured a glass of water on his head, changing him to his female 
form.

All three of the Tendos were startled.  Kasumi's eyes opened wide 
and she said "Oh my!".  Nabiki leaned closer and poked at Ranma's 
breasts, making sure they were real.  Akane jumped up and shouted 
that there was no way she was marrying a sex-changing pervert.

Ranma leaped up and shouted back that there was no way he was 
marrying a girl who didn't even give him a chance and who was 
nowhere near as good looking as his female self and was in fact, 
totally uncute.  Akane got mad, grabbed the table and knocked 
Ranma unconscious underneath it.

Nodoka:  "Ranko, why didn't you stop Akane?"
Ranko:  "Because Ranma deserved it.  I think he thought he 
        deserved it, too, otherwise he wouldn't have gotten caught 
        with such a slow attack."
Akane:  "What do you mean, slow?"

Akane lifted the table up to squash Ranko, but she had already 
crossed to Akane and slapped her in the face.  Akane dropped the 
table (onto Ranma) and brought a hand to her cheek.

Nodoka:  "Ranko, how can you just slap her?  We're guests!"
Ranko:  "Because she deserved it, too.  She didn't even give Ranma 
        a chance before she rejected him."
Akane:  "What do you know?  How would you like to be engaged to 
        some freak who changes sex?"

Ranko sadly looked at her and dumped a glass of water on her own 
head.  Her head hit the roof when Nabiki confirmed her gender 
change.

***************

Ranma and Ranko sat in their room, taking out a change of clothes 
for the bath, both in their cursed forms.  Akane walked past their 
door on the way to her room and noticed it was open a small crack.  
She decided to listen in when she heard her name.

Ranko:  "So what do you think of your Akane?"
Ranma:  "That slow, stupid, tomboy?  I don't know how pops could 
        have engaged me to her."

Akane started to get mad.

Ranko:  "Then why didn't you hit her when you two were sparring?"

Akane listened a little more attentively.  It was true that Ranma 
hadn't hit or even swung at her.  He (or she, whatever) had just 
avoided her attacks and then tapped her on the head.  Ranko had 
certainly shown no such constraint, sweeping her legs out and 
winning their match quickly.

Ranma:  "'Cause... because she's a girl."
Ranko:  "So?  You swing at me pretty easily.  And remember 
        Shampoo?  You defeated her pretty fast."
Ranma:  "That's different."
Ranko:  "Why?  You were both girls.  Is it because you like Akane?"
Ranma:  "Hmph!  No way!"
Ranko:  "Then why are you blushing?"

Akane quietly left the door and continued on to her room, thinking 
about what she had heard.  Maybe she had been a little unfair to 
Ranma.  It wasn't his fault that he had fallen into the Spring of 
Drowned Girl.

Ranma:  "Did mom put you up to this?"
Ranko:  "Of course not.  I'm having all this fun at my own 
        initiative."
Ranma:  "Well, stop it."
Ranko:  "Make me."

Nodoka stood off to one side in her room.  She had heard and seen 
everything (including the resulting fight).  Ranko and Ranma soon 
lay on their back, out of breath.

Ranma:  "We really need to fight people we can beat."
Ranko:  "You said it."

***************

Everyone had finished taking a bath and had gathered in the living 
room at Nodoka's request.  Nodoka sipped at a cup of tea.

Nodoka:  "Now, you may all know that Ranma and Ranko are the 
        heirs of the Saotome School of Anything-Goes Martial 
        Arts, and that Akane is the heir of the Tendo School of 
        Anything-Goes Martial Arts, but there is another tradition 
        to be passed down.  And now that all five of you are over 
        the age of sixteen, I may reveal it to you."

All five looked at Nodoka in surprise.  Nodoka pointed at the Tendo 
girls.

Nodoka:  "Your mother and I were the heirs of another ancestral 
        tradition.  Before she died, she asked me to come and see to 
        your training at this point in time.  You are also the heirs of 
        the Saotome and Tendo Schools of 'Almost Anything-Goes 
        Marital Arts Lovemaking'.  Now, all of you have certain 
        subconscious self-defense "talents" that must be deactivated 
        before your training can begin.  Now don't worry.  These 
        abilities were only implanted in the event that a master 
        from a rival school hunted you down and will only activate 
        if a specific stimulus is received and if you're not attracted 
        to your partner.  I will see to all of you tonight."

Nodoka took another sip of her tea.

Nodoka:  "Now, I suppose I should explain a little about my school 
        to all of you.  The principal behind Almost Anything-Goes 
        Marital Arts Lovemaking is that two people in love want to 
        and can give their partner and themselves greater physical 
        pleasure because they love each other, and all our 
        techniques are designed to effect that or to protect ourselves 
        from people that we do not love.  Do you have any 
        questions?"

Kasumi:  "Why 'Almost Anything-Goes'?"
Nodoka:  "Because while you will learn techniques, whether or not 
        you use them, and with whom, is entirely up to you.  I will 
        not judge you except as it threatens the school."

Ranko:  "Mom?  About those... things that you're deactivating?  
        What are they?" 
Nodoka:  "Just because we are a secret school doesn't mean that we 
        don't have rival schools that will attempt to destroy us.  To 
        prevent that, we programmed our techniques into your 
        subconscious so that if a master of another school tried to 
        seduce you using an advanced technique, you could counter 
        it and not fall under their spell.  When I deactivate these 
        defenses, it will allow me to teach you to access these 
        techniques voluntarily without them kicking in during the 
        process."
