Some facts about my version or other versions of Omegaverse (I am making this since I don't really have a full grasp on the Omegaverse facts and wanted to make my own spin-off in some given facts of the Omegaverse. But feel free to skip through and go to the story if you wish. Just skip through all the bolded words, you will see three line breaks indicating where the story starts):

-If there are two Alphas in a pack, the way to decide the head Alpha varies. If the Alphas are in good terms, they can talk simply talk through it with the rest of the pack present. If not, they obviously fight for the position. In most situations, the Alpha that lost may even have the choice to leave but that depends on how much his pride is broken.

-Omegas before presenting will not always show obvious characteristics of an Omega such as being clingy or touch-starved, maternal, nurturing, and in need of protection. Sometimes, friends of the Omega may be surprise by the change of character. Their tastes and preference of people may change as well. (Like in Koyuki's case, being attracted to Maho. But once he presented, he had no qualms in breaking up because Omegas would usually go for someone more capable of protecting them and it's uncommon that an Omega would be dominant in a relationship.)

-Betas (whether male or female) can get pregnant or impregnate, but the chances are just very slim. As far as I know from what I read in other versions, Betas can usually only reproduce with each other. Or, a Beta female can be impregnated by an Alpha or another Beta but a male Beta cannot be impregnated and cannot impregnate an Omega. In other words, Betas to Betas, their fertility is same as in the normal world but only for male and female. For male to male or female to female, the fertility is rare if both parties are betas.

-In my version, the only pairings that cannot reproduce together is Alphas to Alphas and Omegas to Omegas, regardless of their primary genders. Other match ups are able to reproduce, but the fertility degrees vary.

Alpha x Omega

(Male and Female) - Extreme fertility
(Female and Female) - Great fertility
(Male and Male) - Good fertility

Alpha x Beta

(Male to Female) - Great fertility
(Female to Female) - Good fertility
(Male to Male) - Average fertility

Beta x Omega

(Male to Female) - Great fertility
(Female to Female) - Weak fertility
(Male to Male) - Weak fertility

-In regards to Packs, there are two types. The Casual pack and the Family pack.

For Casual packs, they simply appoint a Head Alpha and follow his or her lead. But there is still a choice to leave it. The ties of the Casual pack is not as strong and can be broken by petty or serious arguments.

For Family packs, the ties are stronger and it is rare for any member who would wish to leave it. The loyalties are greater. If one member is lost, the pain felt is mutual and great. The ways to lose a member is either by death which the pack will mourn for many months, or if the member choose to leave the pack for another. In this case, the Head Alpha of the new pack the member wishes to transfer to must make a vow to take care of the member and keep the former pack updated of anything that happens related to member. A person can change its family pack only once so it is a big decision to make. The Head Alpha of a family pack usually bites each of his or her members on the wrist of each member, except for the Head Alpha's mate, where he or she would bite their scent gland to signify that they have bonded. The only thing stronger the a Family Pack bond is a Mating bond. So in this case, the Maternal Head, or the Alpha's mate usually plays the role of the second-in-command, regardless of secondary gender.

It is to be noted that family Packs are not the domestic type where there are parents and children roles. And it is not necessary that everyone belongs to one. It is a group's decision to form a family pack, and their are no strict laws about going to court or holding a ceremony to go through a Family pack bonding. It can be done in the privacy of the Alpha Head's home.

-An Omega's nest is like a habitat. Omegas' Nests would usually be built either to keep them comfortable or to set the mood for mating. In other versions, it's like as mentioned in Puppylover's explanation in deviantart (A nest is usually a place where an Omega can be comfortable, whether if he is in heat or just having a bad day. It can be a closet or a couch, a small room or a bed. It will usually be filled with soft things, the most smelling like his/her mate if they have one. It usually makes them feel comfortable in all times, even if they feel they are about to murder someone. With Omegas being the small fragile creatures they are, it can help them rest. As they get closer to their delivery date, they will most likely spend more and more time in their nest with their Alpha.) They can get really territorial of their nest. If they have a Mate, even their Mate needs permission before touching it unless the Omega made it for mating specifically.

- An Omega drop is something that happens to Omegas when they are stressed or extremely upset, their minds become clouded and they can't think for themselves. If left unattended, it could be deadly.

-The sweat gland is the most sensitive part of an Alpha, Omega, and Beta's body. Licking or caressing it depending on the situation can either having a calming or arousing effect.

-In my version, ruts and heats usually happen for one week every month. Think of it like a female's menstrual cycle. After four months though, Alphas and Omegas won't experience their cycles for that fifth month and the next will come the month after, or the sixth month and the first one of the four months cycle. (If you still don't get it, look at the calendar. Imagine having a cycle for one week in the month of June, then another cycle in July and August. But for the month of September, you're free from that work. But you would be wary when October comes, because your cycle would start again.)

-A Puppy pile is basically when a pack cuddles altogether in either a cramp or spacious room with the purpose of comforting an Omega or a number of Omegas within the pack. It gives their Omegas a sense of safety and comfort.

The story starts onward. Enjoy! Fixed. I added the information of the schedule of the tour consideration heats and rut schedules of the band members. And now it became a half-year tour instead of fifty days. But that's about it.

Prologue

Koyuki is what people would consider a late bloomer.

When he graduated Middle School, he was the only one of his class that hasn't presented yet. Even Tanabe managed to present as Beta before the year was up.

Koyuki saw this with pros and cons. Con, he was once again different and set apart from his classmates. Then again, pro; His one real friend, Saku, hasn't presented either. He kept expecting him to present at the last minute, maybe even during the graduation ceremony. But no, true to what he said before, Saku never did went with what was popular that even his A, B, O genes delayed their presenting. He did present as Beta though when they started High school.

Another pro, Koyuki didn't have to worry about A, B, O dynamics just yet.

Now it's been months since they performed in Greatful Sound and since they've all seen Ryusuke. Like a lone wolf, the Alpha went off on his own right after. He didn't even say good bye.

There wasn't any real hard feelings between them, but Beck did break up after that. It was their mentality, after all, that "It was all or nothing." That they give their all in every performance or not perform at all.

It was all of them playing in Beck, or none of them at all.

Koyuki and Saku did play in a band, as a request from their classmate, but they never really intended on being official members. And when Sykes had offered him a record deal to go solo, and a cool guitar, it wasn't hard for him to reject it.

Koyuki only wanted play in and for Beck, and Beck alone.

Koyuki felt down, but he tried not to act up too much. He wanted to respect everyone's decision and gave them space. That didn't stop him from trying to get the band back together. It had been tricky. Chiba wouldn't come back, Taira wouldn't come back if it wasn't all five of them in and Saku may come back from moving away if the band was reformed. No one knew where Ryusuke was, even Maho hadn't been completely sure, only that he was most probably okay.

It had been hard saying good bye to Saku when he moved away, he made school life a whole lot easier. So when Koyuki felt weird that night, he thought maybe he was just being overly emotional, because he really wanted the band back together but everyone seemed to be going off their own path. He passed out as soon as he got back to his bedroom, literally. He didn't even make it to the bed when he felt hot and just dropped to the floor. Koyuki assumed he was out too long and came down with a fever.

But at the following day, he presented as an Omega.

~o~

Koyuki had no idea how to feel about being an Omega. He'd always been an awkward, unsure, timid bordering introversion tendencies, boy growing up so he always thought he'd turn out to be a Beta. He didn't have a clue how to handle the expected attention he was getting from Alphas whenever he walked outside now. As much as possible, he went where there were many people, preferably Omega or Beta ones. He was relieved when Chiba finally started considering coming back to Beck. So now he could go watch Taira's gigs and his Live Shows without worrying about being defenseless when he gets jumped at. Of course, Koyuki didn't expect that he'd have to be protected from him, too.

It happened when they spoke to Taira after the show.

Koyuki felt odd and weird so bad after the show that he wanted to head on home, but he had to try convincing the bleached blond bassist again. Paid for his efforts, Taira assured him that he would come back to Beck if all five of them were in and after wrapping up the promotional tour he had with his current band.

Koyuki was ecstatic, even though Ryusuke was a big question mark, he had confidence in the Alpha that he'd show up when they needed him most. All he had to do was contact Saku. And Chiba was just right there.

Speaking of...

Just before Koyuki could celebrate, he felt a wave of heat course through his body, he dropped to the ground, and started to feel really horny. Taira and Maho widened their eyes, realizing what was going down, being Omegas themselves.

Chiba's eyes dilated, nostrils flaring, taking in Koyuki's scent and he let out an animalistic growl. He went for the pounce. But Taira swung his bass case and knocked the Alpha off to the side while Maho crouched down near Koyuki all the while calling for the cops. Not to press charges to make Chiba do time, because he's a friend and it was just baser instinct acting up, but they needed the man power to fight off the Alpha or any others, and a ride to get Koyuki home.

What Koyuki learned? Heat was the worse time for Omegas.

~o~

Chiba apologized profusely the next time they saw and treated him to free ramen his father made. Koyuki was a little reluctant to accept it. He didn't do anything and it wasn't entirely his fault that he went and acted that way. Like always, Koyuki just had the worse luck.

But maybe not completely.

It took a while, but as some people say, better late than never. Beck was reformed. Taira quit his previous band, as promised, Saku earned enough money to return to the area and Chiba still got his trademark energy to pump up people in their shows. Saku got himself disowned in his efforts to return though, but Taira immediately offered the Beta a place to stay in his apartment with him. Koyuki did not miss the unmistakable blush on Saku's cheeks, and silently wished him luck in winning over the Omega bassist.

No word from Ryusuke yet though.

Koyuki never doubted the Alpha guitarist, but for some reasons, it wasn't enough to calm him down. He was really starting to miss Ryusuke.

Very much.

So when they were offered to accompany an official, professional band called F.V.E. on a very long tour in the United States to play as their opening act, Koyuki was all for it and was relieved the others agreed to it. Ryusuke may not be with them at the start, but they were going to where he was. There was a higher chance of meeting up with him there than waiting for the guy to come back to Japan.

Koyuki was just glad Taira was an Omega, too and a strong one at that, and Saku, a Beta. His mom may be cool and laid back about a lot of things, like letting him drop out of school so he can concentrate on music and the band. But ever since his first heat, she would never have allowed Koyuki travel to another country without a fellow Omega. It was understood that they'd always be booking two rooms and the Omegas were strictly to room together.

Besides, someone had to be the main spokesperson. Since Ryusuke was off the grid, and Koyuki being the most capable in speaking English, they seriously needed him to come along. Not that they'd be much of Beck Mongolian Chop Squad without him, anyway.

It had been an exciting experience. It was both Koyuki's first time riding a plane and going to another country. The lead vocalist of F.V.E., David Eric, picked them up from the Air port. He was a pretty nice and mellow guy, for an Alpha. Or at least, so far that Koyuki met. Even Ryusuke had anger management issues, the younger Omega could attest to that. He hated remembering that time when he accidentally broke the guitar Ryusuke lent him.

L.A. Airport had looked like an UFO when they exited it, but the hotel they booked there had been the nicest one. It was probably due to Jetlag, but they couldn't get it together on their first performance night. Chiba sulked about it the most, but one would think that the only Alpha of the group (for now) would be able to hold it together more. But Chiba had always been honest with his feelings. When he was upset, he was upset. Wallowing in misery inside a washing machine was proof of that.

Taira had been tempted to turn it on, just for kicks.

They met other bands too, before they left L.A. and they were all pretty nice. Except when that drummer Alpha had tried to move on to Taira's personal bubble, when the Omega bassist had kept him off Koyuki's. In all honesty, Koyuki's never seen Saku so angry, even when he had slapped Hyodo. He forgot the drummer was only a Beta at that moment, the other drummer definitely thought Saku had been an Alpha, the way he threatened him. Taira had been grateful still, needless to say. A kiss to the cheek showed that much. Koyuki didn't know what to be more surprised by.

That, or the fact that he saw Saku's eyes, wide with surprise.

After L.A., Beck practically lived inside a van the following days. They only booked hotel rooms now whenever Koyuki or Taira were nearing their heats, and if Chiba was in a rut. Usually, when members from either bands had their cycles, they would stay a week longer till it passed in that particular state. When it was F.V.E.'s members in the cycle, it just meant Beck had more time for sight seeing. But it definitely wasn't a picnic when it was Beck having their cycles. Thankfully, the agency F.V.E. belonged to made sure to give them equal treatment. The full payment of Beck's services may be coming when the tour ends, but the agency was gracious enough to double the allowance when the Heats and Ruts were going on for Beck, for medications needed if any or other necessary items, like room service to bring in more pillows, in Koyuki's case.

Taira had actually been louder and more touch starved than Koyuki ever had been so far. Chiba slept at the van at those nights, deeming it safer that way, while the younger Omega stayed and tried to help Taira as much as he could. He also wondered if Taira's horniness was due to the fact that he and Saku had started dating, if a mate, even an unofficial one, made an Omega more needy. The Beta drummer did lend the older male a shirt of his to get him through it, but he didn't expect it to be use for jacking off. Taira had been mortified when his Heat cycle had been over, and Koyuki thought Saku was gonna turn anemic from how his nose bled.

As for Chiba... They actually had to handcuff the Alpha vocalist to his bed just to make sure he wouldn't go off and make unplanned babies. The Omega in Koyuki shuddered, his instincts calling him to submit. Taira had been more mature and in control about it, since he's been an Omega longer, and made sure Koyuki stayed clear of Chiba's practically quarantined room. Saku stayed in the room with Chiba to kept him fed and hydrated, although Taira worried cause while Alphas usually went for the more fertile Omegas, didn't mean they didn't go for Betas. Saku had always been level headed, though, and rationally intuitive, knowing when to back off or prod on. Besides, someone had to look after the guy. He was still a vital member of Beck as much as the rest of them were.

Needless to say, being an Alpha or Omega was hard. Saku's never realized how good he's got it till those nights, listening to the whining and growling.

The Beta wish he could drown out the sounds by jamming on his drum set.

They continued their tour. They played with a band called The Lizards and Koyuki had no clue if the blond they were jamming with was a guy or girl. Taira confirmed he was a dude when he ran into him at the rest room. They actually had more luck selling their CDs after playing with them.

The Live Shows were always awesome, even the one when they had to wear frog hats. Their favorite so far had been the one at Long beach. Koyuki just wished Ryusuke had been with them doing it. He was starting to miss him again, he ended up hugging his Telecaster the guitar he and Ryusuke found together, during a show, much to his chagrin. In all their performances, they didn't really play any songs where Koyuki had to sing solo, he stuck with singing back up for Spice Of Life and Chiba's other main songs, along with Taira and Saku.

For the young Omega, it just wasn't the same singing without Ryusuke there with his guitar, playing along. The band respected that, hell, they agreed with the sentiment.

Weeks into the tour, they were starting to get used to practically living inside the van. Although at times, they were still pissed with having to deal with it, like when they had to pay to repair a flat tire. By the time they got a move on, it was getting pretty late. Still, it did give them a chance to appreciate a beautiful cloudy sky scenery. Once again, Koyuki wished Ryusuke had been around to see it.

Another development with Taira and Saku occurred when they encountered a lot of band members lining up to jam with the Omega bassist. Taira was never one to disappoint, so he jammed with them. Something about them being mostly Alphas struck a nerve in Saku. They had a little spat about jealousy and insecurity. Koyuki and Chiba stayed out of the van as they talked. Honestly, the young Omega never thought he'd see the day that Saku would be discontented with himself, or more to the point, his presentation.

"I'm gonna meet more people, hell, if we're trying to be famous, we both will! You're gonna have to deal if you want to make us to work."

"Of course I want us to work. I just... You're this awesome, talented Omega musician, and you look like you're more suited with Alphas..."

"Yeah, LOOK. That's the keyword."

"... And I'm just a Beta drummer with no real training."

"You're an awesome drummer for being self-taught, Saku." Taira sighed. "A, B, O genes has got nothing to do with talent. So your presentation doesn't matter as far as being a musician is concerned."

"But it does matter when it comes to relationships." Saku interjected. Taira blinked at the dejected tone he was not used to hearing from the Beta. "All I could do was stand and watch as Alphas flocked you. It's not so bad since they were just being friendly, but what if they weren't? I may be able to handle one, but a pack? You deserve a better guy to look after you."

Taira rubbed his forehead, before placing a hand on the Beta's shoulder. "Hey, I'm not just any Omega. Hear me?" He said insistently. "I've been working on being independent and to not simply submit to just about any Alpha, or Beta, ever since presenting. So I wouldn't be letting baser instincts be the one deciding who I wanted to mate with."

Saku looked hopeful. "Who you wanted... To mate with?"

"You got it, Yuji." Taira smirked, planting a kiss on his forehead. "I won't let baser instincts decide that it's you I want to mate with. It's just more real that way, you know?"

Saku blushed, but his smile was wider than it's ever been. "Yoshi..."

Koyuki and Chiba went back to the Live House and ended up crashing on the chairs for the night. It was pretty safe, since Koyuki just finished a cycle last week. The following day, they were only slightly surprised to find that Taira and Saku had officially bonded. Well, Koyuki was slightly surprised. Chiba being Chiba had no clue they were dating, let alone that they were, in fact, having a lover's spat. So he freaked a bit. F.V.E. gave them a day off; they sure needed it.

Koyuki and Chiba, for sleeping on foldable chairs.

Taira and Saku, for... Other activities.

Their tour went on. Making it to New York, eating hot dogs, playing at the CBGB, then off to Texas, San Francisco, and at last Seattle, where things got real interesting.

And that wasn't just due to the Jumping Fish at the Pike Place Market or the Space Needle.

On September 18, Jimi Hendrix's death anniversary, they got a letter from Ryusuke.

After seeing Jimi Hendrix's statue and Chiba having the dream that night at last, they went to pay respects at the deceased musician's grave. That's when Beck and a dog, that looked slightly similar to him called Keith, came running towards them.

And Ryusuke finally showed up.

The Alpha guitarist had a laid back, cocky smirk when he appeared. Saku took a picture, figuring it was Kodak moment worthy. Koyuki felt filled with indescribable happiness and smiled as if he was seeing Sun and stars for the first time.

Little did he know he was exuding hormones. Taira blinked, staring at the younger Omega, having an inkling what it meant. Chiba caught the scent and moved away from Koyuki, not wanting to be given to his baser instincts with the boy again, he had no idea what caused it unlike Taira. Saku didn't have much of an acute sense of smell as an Alpha or Omega had, but he caught a little of the scent. He raised a brow.

From where he stood, Ryusuke caught the scent, and he widened his eyes a fraction, realizing while he'd been gone, Koyuki had presented. The Alpha had always thought he found Koyuki appealing, but now that he's officially presented, as an Omega, no less...

"Oh. Fuck me."

Koyuki finally noticed his friends staring at him. He blinked at all of them, confused. Shouldn't they be more surprised of Ryusuke showing up?

"What?"
