Ranma had been looking for a disguise in Akane's closet while everyone was busy when he found it.

It was a white dress.

It was just a dress.

So why did he feel like he had seen it before.

His hands were shaking.Why were his hands shaking?

I should put it back. I should put it back before Akane catches me in her stuff and freaks out.

He tightened his grip involuntarily.

I'd probably look pretty in it.

Wait. What?

He shook his head.

Men don't think about how they'd look in dresses. Besides Pops and Akane would freak out. And I'd never hear the end of it from Nabiki.

He was about to put it down when he heard footsteps coming.

Shoot, I forgot Kasumi is home still.

Without thinking about it he slammed Akane's closet shut and jumped out the window onto the roof with the dress in hand.

Kasumi's voice came from the window "hm. I could have sworn I heard someone in here but nobody seems to be in. Still I better do a once over. Akane won't be happy if she gets home and something is missing."

Crap.

Think Ranma think.

"Hey what's this window doing open? Akane's been keeping it shut to avoid anymore break ins"

Ranma, now panicking prepared to jump off the roof onto the street next to the house but before he could Kasumi stuck her head out the window.

"Ranma? You haven't been snooping in Akane's room again have you? Oh not that I'm mad at you, but you know she tends to be when you touch her things."

Crap crap crap. Uhhhhhhhh.

In Ranma's panic he accidentally put the dress into view.

Kasumi squinted and then her eyes widened a bit.

"Oh my…"

"It's not what it looks like!" Ranma shouted.

"I… I promised Akane I wouldn't say anything about it but… Ranma, that's… do you remember… that's your dress."

They blinked

My dress? Huh? What was that supposed to mean?

Though it was a nice dress. Not that he'd be caught dead in a dress like this unless he had to disguise himself of course.

"What are ya talking about Kasumi"

He was shaking again.

Kasumi seemed to hesitate for a second.

"Come down into my room Ranma… you deserve to know about this."

Kasumi's room? She never let anyone in her room, it was always locked. And what was it he didn't know. She had asked if he remembered something Akane didn't want him to know.

He climbed back into the window without thinking about it and followed Kasumi to her room, clutching the dress to his chest.

Kasumi put her hand on the door.

"Before we talk about this I'd appreciate it if you don't tell anyone the contents of my room. I try to stick in the background for a few reasons, and I'd rather it not get out.

He nodded. She opened the lock on the door and they stepped inside her room and Ranma raised his eyebrows. It was surprisingly messy.

On one side of the room was a set of weights. Not light ones either. On the wall facing away from the door so that you couldn't see it looking in was a rainbow flag. There was a keyboard pushed up next to the bed with a headset plugged into it and a full body mirror next to the closet, and a bookshelf containing various topics.

"Yes I must confess that it's rather cluttered in here." She said.

"You lift weights?"

"Well Ranma, Akane hasn't always been the only martial artist in the family. Of course someone like me doesn't have time for much beyond basic katas and exercise, so I decided to pursue it more privately. When I was younger I had foolish ideas about how it wasn't proper for a woman to do those things but after all the chaos started I realized I was limiting myself. I'm still working on getting back in the swing of things and I'm quite rusty still but I'm getting better."

He nodded.

"But my. Well we're not in here to discuss me. We're here to discuss you. Or rather. Who you were at one point."

"Who I was? Kasumi what are you talking about? I may turn into a girl when I get wet but that doesn't mean I do girly stuff."

"Ranma… You… how do I put this. Alright I know. So there was this time where you insulted Akane's cooking."

"It's not my fault the tomboy can't cook."

Kasumi shook her head.

"No I suppose not, but anywho she ended up hitting you, and you fell on a rock next to the koi pond and fell unconscious. You were in your girl form at the time."

"Ok so I was knocked out in girl form right? How's that mean I wore this dress. I mean I'd probably look good in it but…"

Kasumi froze for a second before recovering.

"Er. Hem, well. You see, when you came to you insisted you were a girl, and that everything before was like a bad dream you had woken up from. Oh daddy, your father, and Akane were being cruel to you trying to knock you back to your senses at first. Nabiki wasn't home at the time."

She stoped for a moment expecting an interjection but Ranma was too busy thinking.

A… I thought I was a…

"You didn't want to fight anymore, and you kept following me around to try and help around the house. I couldn't find it in myself to hurt you the way they were so I let you help. You were calling me Onee-san."

Onee-san… well kasumi was the closest thing to a sister Ranma had.

Didn't want to fight? Even as a girl wouldn't the art be everything?

"Well… you are kinda like a big sister to me I guess. But I didn't want to fight?"

"Oh yes. You were quite adamant about it." Kasumi responded. "Anywho you ended up getting forced back into your boy form by our fathers but it didn't seem to solve the problem. Akane took you to the mall to try to cheer you up, and at some point while you were there she bought that dress for you. You came back wearing it so happy."

I… Akane bought me a dress?

"Well I'm back to normal now right? Man amongst men Ranma Saotome. It's who I gotta be right? What happened anyways, I had ta go back to normal at some point."

Kasumi sighed.

"Happosai asked you to model something for him and you did. Akane got angry and you told her that the boy ranma didn't exist anymore… she ended up pushing you and you hit your head again. When you came to you were back to normal and didn't remember what happened. Akane swore everyone to secrecy, but I have mixed feelings about the whole thing still."

I modeled for Happosai? I must have really been out of it.

"But… why would I think I was a girl. The curse has never affected my mind before and I still musta known I had it if I got switched back to guy form."

"Well Ranma, I have a few theories but I do need to ask you something. How do you feel when I call you Otouto-chan?"

Ranma frowned. "I'm sorry Kasumi but even though I see you as sister figure I don't feel comfortable being called Otouto-chan."

"I see. And how do you feel when I call you Imouto-chan?"

Ranma smiled and got a weird feeling in their chest, before shaking his head.

"I uh… I'm a guy Kasumi. I know my curse looks like a pretty girl but I…" he choked.

"Imouto-chan. You know how I've been reading medical books right?"

There was the feeling again In their chest.

"I uh… yeah I geuss, ya've been borrowing em from tofu right?"

"Well… you see. There's this thing that's being researched in America called GI disorder. It's when your gender and your sex don't align.

They blinked.

"Aren't gender and sex the same thing though?"

"By some definitions yes? But under this framework, well. Gender refers to your internal identity, while sex refers to what your organs say. Sometimes these come into conflict with each other for reasons we don't fully understand… Those unfortunate souls with gender identity disorder feel a discomfort in their body and a desire to live as the opposite gender. Oftentimes without even realizing it. I started researching it because I was worried about how the curse might affect you but after the incident, I started to realize things might be going the opposite way."

Ranma's breath hitched.

"But I'm a guy… I mean I gotta be a man amongst men… it's… I mean no guy really wants to be a guy right? Besides, I can't be a martial artist if I'm a girl!"

Their breathing got heavier, and Kasumi gave them a sympathetic look.

"Ranma…how many women do you know that are marrial artists dear. Your father has many wrong ideas he's attempted to pass on to you. And men without gender identity disorder are fine with being men… so I need to ask. Do I have 2 little sisters? Or 3."

Tears started coming out of ranma's eyes.

"I'm… but… but I gotta be a… be a… I… Onee-san? I… but…" ranma started sobbing.

Kasumi Hugged her

"Oh Ranma. It sounds like you know what you want… Imouto-chan."

Ranma bawled even harder as her big sister held her.

A little while later Ranma was looking in the mirror in Kasumi's room, her pigtail had been taken out and put into a much looser braid. She was in the dress. Her eyes were puffy and red, but…

"That dress really does suit you, Imouto-chan." Kasumi said

Ranma giggled. Oh it felt good.

"I… you really think so?"

"Yes. You look wonderful."

Ranma turned around and hugged Kasumi again.

"Thank you, Onee-san. I don't think I'll wear it often but… but thank you. You've done so much for me. For everyone in this house really. Even pops owes a lot to you."

Kasumi smiled even more. "Anything for my family. Besides, all I really did was be honest with you and provide you with some information you didn't know."

"Don't sell yourself short big sis! Besides we should be pitching in more around here. Tell you what you want to get back into martial arts right? I can help you with that and some chores around the house so you have some free time."

"Oh I wouldn't want to impose."

"Don't be silly big sis. Yeah I might be a bit of a tomboy but that doesn't mean I can't help ya out. Besides like you said, anything for family right? You helped me, so let me help you!"

Kasumi chuckled.

"Oh if you insist. We still need to figure out what to tell Akane. I suppose it would lessen things somewhat if I were to come out too."

"Yes, and I suppose you would be too. Unless of course you also like men. Or if you secretly only like men and you were just forcing yourself to like girls."

"hu. well this explains a lot"

"Yes, and I suppose you would be too. Unless of course you also like men. Or if you secretly only like men and you were just forcing yourself to like girls."

"hu. well this explains a lot"

"Oh no, dear. You see people like you are part of the wider community. Personally I'm a lover of women. You see that flag on the door behind you? That's the flag for people like us."

"… that means you like girls right?"

"Yes, and I suppose you would be too. Unless of course you also like men. Or if you secretly only like men and you were just forcing yourself to like girls."

"That sounds like a lot. I guess I'm probably the only tfem person to accidentally fall into Jusenkyo. Got real lucky there."

"I'm happy for you Imouto-chan."

"Thanks Onee-san! I don't know how I'm gonna tell everyone, but I'm a girl, and Ranma Saotome don't loose!"

She was determined to live the way she wanted to Panda and fianceés be damned!

"Yes, and I suppose you would be too. Unless of course you also like men. Or if you secretly only like men and you were just forcing yourself to like girls."

Thanks for reading. I haven't done any works In a while but Ranma 1/2 helped me be me back in December and I've had different varients of this idea running through the back of my head ever since. I'm pretty rusty so any input is appreciated! bye!
