I just randomly got this idea in my head some time ago and started thinking about making a story… but I'm terrible at putting all the scenes I thought up together, so I decided to make it a challenge instead.

(I'm going to start with a small character chart (so to speak))

Name: Mariam Black – Escanor (alias Susan Vandom)

Hair color: Red (what shade of red is up to you), blue when using a glamour

Eye color: Emerald Green, brown when using a glamour

Height: 165 cm

Personality: Mischievous (she's a second gen Marauder), motherly but has a mean temper when provoked (I think mother dragon is a good comparison…)

Family members: Lord James Potter (father), Lady Lily Potter (mother), James-Sirius Potter (alias Thomas Vandom (because I don't want him completely out of the picture)) (brother), Prince Phobos (husband) - it was arranged and they didn't like each other at first but eventually fell in love (for the sake of the story make him older, so they are both 15-16 when they get married and have Will), Wilhelmina Black – Escanor (daughter), Queen Weira and Consort Zanden (in-laws) and Elyon Brown (Escanor) (sister-in-law)

Occupation: A doctor (I know it's different from Canon Susan's job but this could work)

Favorite movies: Mamma Mia! and Star Wars (Funny twist: Mariam/Susan wanted to call Mr. Huggles (the dormouse) Darth Sidious (or Darth Maul) at first).

Moving on to the actual challenge;

1) Mariam/Susan left for Earth to visit her parents just a few days (or weeks, whichever) before the Veil came into being because she and Phobos had been having arguments for a while. I'd like the reason to be an outside influence (like Nerissa for example). My reason for that being that there are very few fics where Phobos is really a good guy or at least a decent guy.

2) Because she doesn't have the ability to open portals, Mariam/Susan and Will have to stay on earth. This hurts Mariam/Susan and she rarely talks about Meridian and Phobos to Will. Meaning that, while Will does know about her father she doesn't know who he is. (Or something along those lines… Feel free to change it if it doesn't fit with your ideas)

3) Because I can be a cruel and sadistic b***h, the Guardians accidently kill Will's mom. Will blames herself because only then did she find out her father's name. (Because they rarely had time to talk about things after Will became the Keeper of the Heart) Later, Will "retires" from being a Guardian. The Oracle is understanding and does say that normally princesses aren't selected as Guardians because of their duties to their planet's people.

4) Will can't stay in Heatherfield and moves to Italy, where she and her mom lived for two years when she was 7-9. She decides to learn swordsmanship because it fascinated her after seeing Caleb and others Meridian natives use swords during battle. Her teacher in the art is a crazy man, who she starts cursing after a month and especially when he decides they should go to China. Specifically the Jusenkyo springs. (This is the only mention of Ranma ½) She "falls" in the Spring of Drowned Boy. As a boy, Will looks a bit more like Phobos than as a girl. (Btw, Will's hair is (as a girl) either reddish blond, strawberry blond, red with blond streaks or blond with red streaks (once I thought about a Harley Quinn hairstyle but decided against it) and her left eye emerald green and her right is grey (when not under a glamour that is)). Her, his, teacher is cackling at her, him, until she, he, throws him into the Spring of Drowned Pig. Will says s/he won't be called Wilhelmina Black-Escanor (that would be awkward but hilarious) when a boy, but Squalo Superbi.

5) Pairing could be either Squalo/Yamamoto or Squalo/Xanxus. Either is fine by me, but it would be more fun with the latter. Especially since I thought that Will keeps having the bad luck of getting splashed with cold water constantly, so she mostly stays as a boy. Will gets so used to being Squalo he sometimes forgets he's actually a she. A hilarity factor would be that sometimes Squalo slips and acts and talks like a girl, confusing the Varia. Another could be that when Squalo is a girl and by extension has her period (which happens rarely); she'd be immobilized by the pain (just think about the PMS when she isn't groaning in pain). She could be bitching about anything and everything (like having to learn how to speak like a boy and a girl in some languages (I imagine it would be pretty hard…)).

6) The only ones to know Squalo is both male and female are I.T.C.H., Caleb, Matt, Blunk, Phobos, Elyon (everyone in Meridian really… they usually address Squalo as "Their Highness", rather than Princess or Prince, unless they know for sure which one Squalo is at the moment… Hilarious *cackle*), Lussuria (there's no way he wouldn't know), Mammon (he'd never tell, since almost nobody knows his actual gender and he's an Arcobaleno so he should know when someone is cursed) and the now deceased Vongola Ottava knew. With trying to tell Xanxus Squalo keeps having problems until the battle with the Vindice (this is optional) since at least someone should be able to tell Squalo's original gender. I'd imagine it could go something like this:

"You're a woman!?"

"Yes!" Squalo shouted frustrated, nearly pulling at his hair. He'd been trying to tell Boss for ages now.

"You certainly don't look or even sound like a woman!" Xanxus bellowed back. Squalo's eye twitched.

"I know that. It's a curse. I'm male just most of the time. And you have seen me as a woman once."

"I didn't see any difference to how you usually look or sound. You were just as loud and annoying as ever."

"That's because I was having my period! Those are a pain to deal with!" Squalo roared. There was an awkward silence and a few coughs and some people (like Levi) were reduced to a blubbering mess. Xanxus' cheeks even went pink. That wasn't something he necessarily needed to know. And the shark didn't have the decency to look at least a little uncomfortable having said that. If anything he (or was it she?) only looked annoyed.

"That was how the miser found out."

"And they didn't tell on you?!"

"No. Neither did Luss, though he did try. He's always known. Ottava knew too. How she found out, I'm never talking about. Ever."

During that Lussuria skipped next to Squalo and handed him a thermos full of worm water.

"There you go Squa," he cheerfully said.

"Thanks," Squalo said after pouring some water over herself. She looked down at herself and frowned thoughtfully. "Hm, is it just me or did I grow since the last time I checked?"

"It's not just you, darling. You're a D-cup most certainly," Lussuria agreed with a nod.

Most looked like they'd been slapped silly with a fish. Xanxus was practically catatonic. The shark actually looked… appealing. Her hair was slightly longer than it was as a male and her different colored eyes looked good on her. And like she'd casually mentioned her bust was apparently bigger than last time.

"When was the last time you were a… girl?" Bel asked curiously. He was one of the first to come out of his shock.

"About two years ago. For more than a few seconds. I attract cold water like nobody's business, so it's really easier just staying a guy. Even if it was awkward at first. Especially when I went to my father's home as a girl and shortly after it starts raining. I had a fun time explaining it to my aunt and friends," Squalo bitched.

"Not to your father?"

"He was still in prison at that time. It's complicated and involves centuries worth of traditions."
