Wow, okay. FF hates my section separators. Somehow it even hates the section separators I used for "Worlds." (EDIT: nope! They deleted those too. Man, no wonder no one liked that story. I've reuploaded it with proper separators now, but apparently it might take 30 min for the changes to take effect.) This is going to be a pain, particularly on chapters which have a great many sections. I deleted the story and am reuploading, so I hope no saw the first version and got confused by the lack of separation.
The proper title of this story is "Don't Piss Off Demyx," but I didn't want to risk upsetting ff or AO3, so it's officially "Don't Anger Demyx."
So, absolutely no one was interested in the first story of the "It's Okay for Demyx to Have Feelings Darn It Verse" series. I can't help but want to be optimistic and try again. Here's the first chapter of the second story.
The story has a total of 13 chapters. It is A/B/O with a twist about Betas. It is rated M for a few smuttier scenes (including two full blown sex scenes), language, some abuse. Word of warning: there are a total of two rapes in this story, one is talked about for one second and gets immediately erased from the time line, the second happens completely off-screen and toward the end of the story. There is also an attempted rape and threatening of sexual assault. Overall, this is a fluffy story, I swear... I swear... Okay, it's fluffy with dark scenes sprinkled in. There is no mpreg.
Endgame is Xigbar/Demyx/Zexion but there are other pairings as well.
The full story is posted on AO3 but I'm crossposting it here because I am a review wh-.
I'm assuming you haven't read "Worlds," which is fine, but there is background info you need from "Worlds" to better understand this story, as it comes from the same head cannon verse. Here is the info:
1) Demyx's home-world is Eårth, an alternate Earth with no Kingdom Hearts games
2) Demyx is Kingdom Hearts' chosen protector of the Realm of Light. Because of this, he doesn't age
3) Demyx is the MoM and the x-blade is his Heart (which he produced instead of a Heartless). Because of this, he always has feelings
4) When Demyx was first sent to the Realm of Light, he traveled throughout the RoL's original timeline, allowing him to time travel
5) Breaking the x-blade gives Demyx amnesia
Don't Piss Off Demyx
In which Demyx is confused (Age of Fairytales Part 1)
It's not like an explanation of secondary genders came with the universe hopping, time travel care package. Demyx had had to work out a lot of things for himself, such as rewinding time after the first time an experiment went wrong and oh Kingdom Hearts, Luxu died. He'd ended up accidentally rewinding time all the way back to that first day, when he'd wandered around the plaza of Daybreak Town, lost and uncertain, knowing that he had to save the Realm of Light but it was all just too much. He'd sort of crumpled by the water fountain, ignored by indifferent citizens, until a boy with soft, fluffy looking hair had walked up to him and sweetly asked if he was okay and "can I help?"
Demyx loved fluffy things. (And sweets.) The only way to keep the temptation of constantly petting fluff at bay, clearly was to put a hood on that temptation.
Then there was that time he was absentmindedly thinking about how much he wanted to visit the ocean and humming to himself, sitting at his desk and tapping his fingers, when he heard a scream, and turned to see No Luxu and a peculiar dark hole thingy and oh Kingdom Hearts, Luxu drowned. Oops.
So, yeah. Demyx was constantly figuring things out for himself and having to rewind time each time Luxu died—which was suspiciously often for a boy who wasn't a troublemaker. (He'd had to save him from that disastrous first experiment multiple times before he just gave up on it completely because Luxu would not listen when he said, "don't touch," and "stay five feet away," and "STAY OUT OF THE BUILDING, LUXU!... Damn it.") So Demyx could forgive himself for not having heard of this secondary gender thing even though he'd already been in Daybreak Town for about a year of real time, nine years of rewinded time.
He learned about it when Luxu marched in one day, upset because a mountain of a boy (who in a future timeline would already be a fellow apprentice) had made fun of how scrawny and soft and un-Alpha like Luxu supposedly was. Demyx's blank stare, tilted head, and "huh?" upset Luxu.
"I know I look like this," he waved a hand at himself, blushing with shame and embarrassment because apparently the Master didn't think him worthy, "but I am an Alpha."
"...What's an Alpha?" Demyx wondered if the automatic universal translator Kingdom Hearts had seemingly given him was faulty. It happened sometimes: he'd say something that was perfectly normal, double entendre free English, but Luxu would look shocked and flustered and ask how he could say something so dirty. The one time it went the other way around, Demyx found himself choking on air and wondering how his sweet Luxu could possibly say... no, he couldn't even bear to think it.
"An Alpha is... an Alpha." Luxu replied helpfully. "Master—" "Demyx" "Master, didn't you learn about Alphas, Betas, and Omegas at school? Or from your parents?" Demyx went very still. Myde had heard of those terms from a few of his friends. He'd heard that the concept originated in a certain fanfic fandom before spreading to other fandoms and even Japanese BL manga and Chinese danmei novels. He silently prayed to Kingdom Hearts that he was not in an A/B/O world.
"Explain it to me... as if I've never heard those terms before."
And Luxu did.
In the Realm of Light, everyone had a secondary gender. At some point, everyone got tested. Tests varied; currently a blood test was the most common. But there was hope in the scientific community that eventually tests could be conducted via brainwave scan, a presumably faster and more accurate method than anything currently out. Of course, an untested person could just wait for his or her heat or rut or calming pheromones, but that would just be too dangerous. The population was fairly evenly divided among the six possible varieties of genders and secondary genders. And thankfully, gender discrimination didn't seem too bad.
The Alphas were the "males" of this world, supposedly always full of testosterone, and liable to go into ruts when around omega in heat. Other than their rut pheromones, they could emit pheromones when they were angry or feeling particularly dominating, designed to force the target(s) to submit. The stronger the Alpha, the more he or she could force other Alphas to submit.
The Omegas were the "females" of this world, able to give birth, and were stereotypically supposed always to be nurturing and soft. They go into heat for a few days every month, with the time varying from person to person, much like a Beta female's period. They would emit a pheromone that could trigger any nearby Alpha's rut.
The Betas were generally the happy medium between the other two. Males couldn't give birth, but females could. They were able to emit pheromones that could either calm or ramp up an Omega's heat or an Alpha's rut. As such, they were considered essential to the health and well-being of the other two genders. Omegas who had found a compatible Beta wouldn't have to take time off from work every month, because the Beta would make his or her heat go away. Rape caused by heat was fairly rare, and happened only when there were no compatible Betas around to help calm the Omega and Alpha, or if a Beta became criminally minded.
Beta compatibility was an important factor. Not every Beta was compatible with every Alpha or Omega. As such, trios and quartos were considered the norm for lovers. A couple was just a Beta and an Alpha/Omega who hadn't found a corresponding Alpha/Omega yet. A Beta would attach him or herself to a compatible Alpha or Omega, and sometimes when the Alpha or Omega found an Alpha or Omega lover, he or she would already have a Beta of his/her own. Open ended relationships and "pack Alpha/Omega" were common too. It might take time for the Beta to find a suitable partner for his or her lover, or the Alpha/Omega just might not be suitable for settling down with anyone other than the Beta. And relationship finding was usually left to the Beta.
Betas tended by nature to pay attention to the details of what their chosen partner needed and wanted, so when courting an Omega, the Alpha (or his or her Beta) would usually make his or her interest known to the Omega's Beta first. This allowed the Beta to screen out unwanted suitors without the Omega having to risk confrontation. Most Betas would usually confirm every acceptance or denial with the Omega anyway, so it was more out of courtesy, tradition, and safety, than anything else.
Demyx's head was spinning. He was happy that this world seemed more tame than the horrors his friends had led him to believe this world could contain. But the idea of being with multiple people being the norm was a little much for Demyx's almost virgin brain to handle. But did he even have a secondary gender...? His world didn't have any, perhaps his secondary genderless state had transferred over? Nothing weird had happened to him, he hasn't gone into this heat thing. Perhaps he should get tested...? But no, that would require his blood getting drawn. Nooooooooooooo... Well, he'd leave that bit of cowardice under wraps, can't let the kid think less of him, now.
While he was thinking, Luxu cut in: "Perhaps I should try emitting Alpha pheromones and see how likely you are to submit? You seem like you'd be an Alpha to me, Master." "Demyx." "Master."
Demyx sighed. Man, was Luxu ever stubborn. He couldn't understand why the boy kept calling him, "Master." It certainly hadn't been his idea.
"Yeah, sure. Give it a try." Luxu stood up and squared his shoulders, standing as tall and as confident as his (short) height would allow him. Soon, a pressure filled the room. Demyx felt himself slowly growing angry. He twitched, repressing the quickly growing urge to punch Luxu in the face. "Luxu," he said as he gritted his teeth and held his clenched right fist down with the left hand. "I think you'd better stop whatever it is you're doing." By the end of the sentence he was practically growling. He felt something building inside his chest, trying to get out. All at once, the feeling rushed out, and now it was his pressure in the room. Luxu was... Luxu was blushing? He'd sat back down and seemed slumped in his seat, cheeks flushed, eyes glazed, and slightly panting. The shock of such a weird sight knocked Demyx out of his strange mood. The pressure in the room quickly faded.
"Yeah," Luxu said in a breathy tone before clearing his throat, "you're definitely an Alpha." For some reason, he looked a little disappointed.
Is Demyx an Alpha? ╮(╯▽╰)╭ Place your bets! (Luxu's definitely a pervert. That reaction wasn't normal.) My clue for you is: because Demyx is from a secondary genderless world, he's definitely not normal. Demyx will find out the truth once Vexen tests him, but that probably won't be next chapter. I still have more Fairytale Era stuff I want to write first, the better to confuse you on Demyx's gender with my dears. I already know what most of the Org members genders are, but I'll wait to post that once they actually show up.
I hope my explanation didn't bore anyone. I wanted to give enough detail for anyone who wasn't familiar with some of the tropes of the concept, but make it original enough it didn't bore people who've read the explanation way too many times. Still, it ended up being quite a bit of exposition.
