A/n: So uh...It appears my sort of past obsession with corpse party has revived itself...So I've been working on a couple of fics recently and have decided to split this one into two chapters instead of one ridiculously long one.
I've never written an alpha/beta/omega fic before but this idea wouldn't leave me alone until I wrote it so uhh...here it is!
I've also been somewhat desperate to actually upload something because everythingI'm currently working on is fairly long and/or time-consuming (Including a multi-chapter AU with this pairing because I'm trash hehhe)
But anyway, enjoy this first chapter of a rare-pair fic!
Full summary (Because it's too long): Satoshi had never so much minded being an omega, after all, he had pretty much planned out the majority of his life after high school. He would confess to Naomi who he was pretty sure felt the same about him and everything would be fine, after all, she was an alpha.
But then everything turns to chaos as he and his classmates are thrown into heavenly host elementary where he goes into heat, discovering things about himself and others until they eventually escape.
It was promised that everyone would forget about what happened and it was never spoken of again only, Satoshi was left questioning his feelings, for Naomi, and for his best friend...
The nightmares started as he approached his next heat, with vivid visions of himself going into heat in that cursed school with no one to save him...only, there is one person who can help.
He finds his nightmares almost disappearing whenever he stays over at Yoshiki's and realises his original life plan may not have accounted for this small plot twist.
He was in love with his best friend...
Satoshi had never so much minded being an omega, after all, he had pretty much planned out the majority of his life after high school. He would confess to Naomi who he was pretty sure felt the same about him and everything would be fine, after all, she was an alpha and he was an omega.
But then everything went wrong.
The supposedly harmless charm they had done on Mayu's last day had plunged them into the cursed school known as Heavenly Host Elementary and to make matters worse, Satoshi's heat had started prematurely.
He had searched the school high and low with Yuka however, an earthquake separated them just as his heat started getting worse. He had woken up after the earthquake somewhere unknown, his stomach cramping painfully. His head was pounding at this point and he found it harder to concentrate as he tried the door, finding it locked from the other side. With a sigh, he tried searching the room instead, finding an article written about the children they had seen as ghosts who were apparently killed by a teacher at the school. He felt his stomach turn as he read through the article, discovering the extremely gruesome ways in which they were killed. He wasn't the best with this sort of stuff at the best of times but his heat was making him even more sensitive than normal and he felt fear and disgust settle in a pit in his stomach. Knowing the strange ways in which this school worked, he decided to check the door again, finding it still locked and letting out a sigh of frustration which was cut off as he turned around, seeing a girl around the same age as himself staring blankly at him before her mouth stretched into a grin.
"An omega huh? You're going to have fun here"
The worst-case scenario immediately popped into his head and he felt adrenaline rush through his body in fear. Surely there's only one thing she could mean by that..?
Before he could overthink the statement anymore, he felt burning pain blistering on his skin, similar to what his heats usually felt like, only so much worse. It was as if someone was poking hot needles into his skin with no mercy however, he vaguely managed to catch her last words.
"Go to the one who occupies your thoughts..."
His last thought before falling unconscious was a mental list of who that could possibly mean.
He'd been desperately trying to find Yuka, although, he was also worried about the others. Maybe it related to her comment about him being an omega? If that was the case then surely he would have to find Naomi?
His thoughts were cut off as his vision went black, leaving no room for any other logical thought or reasoning.
When he next awoke, he found himself somewhere in the second building once more, sitting up and looking around groggily, trying to work out where he was despite the discomfort lingering in his lower abdomen. He stood up, his legs turning to jelly for a moment, forcing him to grasp the wall for support before making his way down the hallway he was in, trying to remember which floor he was on.
Maybe Yuka would be here...
He continued walking, a small flicker of hope sparking inside him, even managing to avoid flinching at the loud slamming of a door somewhere behind him.
Only, flinching wasn't the worst of his worries.
He spun around, hoping to see his sister running towards him, or possibly one of his friends, however, what he saw instead was indeed another student, however, not one he knew.
The newcomer had a grin stretched across his face, a manic look filling his eyes as they locked on Satoshi. He was clearly an alpha, if both his build and the red seeping into his eyes were anything to go by and his tongue darted out to lick his lips and he spoke in a low, singsong voice.
"An omega? And one in heat? You should really run, I'll give you a head start..." The taller male laughed manically and Satoshi felt his blood run cold in pure terror. This was going to end badly if he didn't start running, now.
And so, he spun back around, taking off down the corridor and hoping to any sort of god he could that this would lead him somewhere other than a dead end.
"Run, rabbit, Run..." He heard the cackling behind him as his feet pounded against the wooden floorboards, a small part of him was afraid that his foot would break right through them however, he couldn't spare the time to stop and worry about that. He mentally breathed a sigh of relief as he found he reached the ground floor after one set of stairs, immediately following the vague memory he had of where the main entrance was. As soon as it came into view, he sped up subconsciously, his fight or flight response kicking in and he practically yanked the door off its hinges, almost crying out in relief when he found that the door wasn't locked.
Continuing towards the other building, he got lucky and found that this door also wasn't locked, rushing inside before realising, he was alone. What was he supposed to do now? He could only run for so long...
His only option was to fight the other student off but he wasn't sure whether he would be strong enough, especially if they were an alpha. He paused for a moment, trying desperately to think of how he could get out of this situation, however, it appeared he had overestimated how much of an advantage he'd gained as he heard the heavy footsteps and dark laughter behind him, immediately spinning around to see the manic looking student grinning at him, his eyes now fully blood red with pheromones wafting off him, making Satoshi gag.
"You didn't run fast enough, rabbit,"
He tried backing away only he stumbled over a broken wooden chair laying on the floor behind him, falling to the ground with a loud grunt. The air around him was thick with the scent of distress as the taller student climbed on top of him, leaning down to lick at his neck with a wicked smirk as the brunette cried out, unable to keep his fear hidden any longer. His eyes squeezed closed however, he heard a loud crack and felt the weight pinning him down release.
"Shinozaki, get Satoshi out of the way! I'll deal with this,"
The brunette scrambled into a sitting position, seeing Yoshiki wielding some sort of metal pipe along with the other student holding his head tightly where he had obviously been hit. That was if the blood dripping into his eyes was anything to go by.
"Mochida, come on, we need to get out of here," Ayumi's voice sounded desperate however, Satoshi's eyes widened in surprise, glancing between her and Yoshiki.
"We can't just leave him though," Satoshi protested, flinching as Yoshiki swung the metal pipe at the students head once more as he moved to attack. They both flinched away as the pipe connected with the person's skull with a sickening crack and his body fell limply to the ground.
Yoshiki spun back around to face his classmates, eyes flicking between them and the now unconscious student before coming to rest on Satoshi, scanning him for any injuries as he asked
"Are you alright?"
The brunet struggled to his feet, his legs shaky in fear and he found himself having to grasp the wall for support, nodding unsurely.
"Yeah, I'm fine, just a little shaken up,"
Yoshiki nodded, clearly controlling his breathing as the scent of an omega going into heat threatened to distract him, however, he reached down to pinch his leg hard, snapping himself away from those thoughts. He would die before he let anything happen to Satoshi. To either of them. Luckily, his thoughts were quickly distracted further by Ayumi.
"We should go, we've got Nakashima's student ID so she must be around here somewhere. And we know how we're supposed to get out of here," She stated, taking one last glance at the lifeless body lying behind Yoshiki.
Everyone agreed and they made their way up to the second floor, searching around for anything new since the last earthquake and coming back with nothing except for new holes in the wooden floors. The most noticeable of which seemed to be exactly what they had been looking for as the came to a halt at the edge of the hole, spotting two familiar figures on the other side.
"Nakashima! Yuka!" Ayumi grabbed the pair's attention and Satoshi felt his heart lurch knowing they were both alright. "Are you two both okay?"
They both seemed just as surprised to see them, standing on the other side of the hole, close enough for them to have a brief conversation, with each of them explaining the tragic deaths they knew of as well as sharing information about how to escape. After discussing what to do next, they went their separate ways again, determined to find Naho's notes to finish the last few pieces of the puzzle. They all knew they had a time limit. Not only the one set by the school before another earthquake separated them and scattered everything they had found but also a time limit before Satoshi's heat kicked in further, rendering him unable to do much, not even move without great difficulty. And so, they hurried to find the rest of the notes, finally reaching the third floor and running into Naomi and Yuka again who revealed that Morishige had also died.
They were so close to escaping, they couldn't give up now, no matter what. Satoshi had joined his sister and Naomi at Yuka's stubborn insistence and they headed off to find what they were supposed to do next. He felt confusion running through him as he felt a desperate yearning inside him as they walked away from Yoshiki and Ayumi, however, he shook it off, focussing on the task at hand, getting out of this hellhole alive.
More searching led them to find the black cat plushie which had been a gift to Sachiko from her mother and they had eventually found there way down to an abandoned bomb shelter where Naomi ran off, chasing after Yoshikazu who had been dragging Seiko's corpse along before Satoshi and Yuka had met up with Ayumi and Yoshiki once more. Satoshi had a bad feeling about the entire situation at this point however, he followed the others into the last room, seeing the three appeased ghost children along with Sachiko's corpse and her angered spirit. They all found themselves paralysed by the ghost who caused all of this as she freaked out, lunging forwards and plunging a pair of scissors into Yuka's stomach, wretching a cry from her as Satoshi tried to hold out her tongue and the cat plushie in an attempt to appease her. Luckily, it seemed to work and they were all released, however, Satoshi fell to the floor, his heat finally kicking in fully, and at just the wrong time.
He felt the floor start to shake and vaguely heard one of the ghost children explaining they needed to go outside before Yoshiki's hand gripped his arm, dragging him along as he stumbled to keep up, all the while mumbling an apology.
The rest of it seemed to blur together to Satoshi however, he noticed that at some point Naomi had rejoined them as they reached the forest outside the school, each pulling out their scrap of paper in varying states of awareness.
The next thing he knew his world turned bright white, almost blinding him.
Was he dead?
Were they back home?
He had no idea...
But this floating feeling seemed almost...nice...
He wouldn't mind this for a while...
Yoshiki found his consciousness slowly returning, along with a pounding pain in his skull as he tried to squint his eyes open and look around. What he saw almost made his heart stop with relief as he saw their familiar classroom...their real classroom, complete with the decorations left over from the cultural festival and the silly drawings covering the board from Mayu's leaving party. Forcing himself to sit up, he noticed both Ayumi and Naomi in similar states of semi-consciousness, sitting up and looking around dazed and he spotted Satoshi and Yuka both still unconscious across the room.
"We're back..." Ayumi sounded both shocked and relieved as she slowly stood up, reaching out to touch one of the tables, just to ensure it was definitely there.
"Mm-hmm," Naomi mumbled in agreement, eyes glazed over with tears.
They all noticed Yuka beginning to stir slightly, a cry of pain escaping her as she clutched at her stomach where Sachiko had stabbed her only, there was no blood there. Only a phantom pain which lingered from the school, the only evidence they had been there at all.
Naomi had stood up now, moving to grab some water for Yuka however, Satoshi still lay unconscious near the door to the classroom. Yoshiki frowned in concern, approaching his best friend to try and wake him up, however, the smell of heat hit him full force as he got closer, meaning it was likely that as soon as the brunet awoke, he would be fully in heat.
Which wouldn't be good with two alphas around...
Whilst Yoshiki liked to think his self-control was higher than average, even he wouldn't be able to fight against natural instincts if Satoshi were to wake up. For now, he could always hold his breath and control his breathing, ensuring that he stayed in control. He noticed the other's eyes on him and turned to them with a small sigh.
"We should all get home. I'd rather get Satoshi home before he goes into heat if possible," The blond spoke, already expecting Ayumi's protests.
"But he's unconscious, how can you get him home without waking him up?"
"I'll carry him," Yoshiki turned away in time to miss the look of anger and disbelief thrown his way however, he couldn't avoid Ayumi's verbal protests.
"Kishinuma, he's in heat, do you really think you'll be able to control yourself right now?"
"What else do you expect me to do? No-one else here can carry him, or do you want me to wake him up so that he's in pain and desperate? There's no good way to do this but if he wakes up there's nothing any of us can do to help," Yoshiki could feel his blood boiling in anger, although he knew it was irrational and he made his way towards Satoshi after taking a deep breath.
After struggling somewhat to find a comfortable position to carry the omega in, Yoshiki turned to Ayumi and Naomi, with a questioning look, Yuka already stood beside him, eager to get home after the entire ordeal.
"We're coming," Naomi answered for the both of them, grabbing Ayumi's arm and following after Yoshiki who had already set off out the classroom with Yuka close behind.
He would have been lying to say that it wasn't hard to keep his cool, after all, Satoshi smelt so good, and it wasn't like it was even from a distance. That along with the fact that Satoshi was his best friend, pretty much the only person who knew even the slightest thing about him who was now in heat in his arms.
Well fuck.
He quickly derailed his train of thought before it went too far, glancing around to see Yuka walking quietly beside him and Ayumi and Naomi following after them.
"You both live nearby right?" Yoshiki asked before adding "I'll walk you home. It's late, and after everything that's happened..."
The two nodded and so, they headed to both Naomi and Ayumi's houses, agreeing to all go to school tomorrow to discuss what on earth had happened, minus Satoshi obviously as he would most likely be bedridden for a week or so after he woke up before Yoshiki and Yuka headed towards the Mochida household with Satoshi thankfully still unconscious. They were greeted at the door by Satoshi's mother who gasped in concern seeing Yoshiki carrying her son.
Yuka brushed off their mother's concerned questions as Yoshiki explained how Satoshi was going into heat and had passed out, conveniently missing out the part about the cursed school for now.
Luckily, no further questions were asked and the blond found himself quickly ushered into the house, being led upstairs by Satoshi's mother regardless of the fact he already knew their house like the back of his hand. He adjusted Satoshi's weight as they entered the brunet's bedroom, placing him down gently on his bed before stepping back and taking a deep, steadying breath before turning to leave.
Satoshi's mother thanked him enthusiastically, offering for him to stay the night which on a normal day he would have accepted however, it wouldn't be worth the risk. Satoshi's scent had been getting stronger ever since they left school and although he didn't show it, he was finding it harder and harder to keep his cool, having to force himself to ignore the omega's alluring smell in order to get him home safely. And so, he thanked Satoshi's parents for the offer and left, taking a few deep breaths as the cold night air hit his face.
He had never thought he would be attracted to the same gender however, the more he thought about it, the more blame he placed on his sub gender. He wasn't attracted to his best friend. He couldn't be.
It was purely down to the fact that he was an alpha and Satoshi was an omega about to go into heat.
With another deep breath and this reasoning playing his head like a mantra, he set off home, not caring about the cold breeze that picked up as he walked. After everything that had happened, he felt strangely numb, not even feeling the cold, even as rain began dribbling from the sky when he was a couple of streets away from his apartment.
He reached his apartment building, heading up the stairs to his apartment on the second floor and finding the dim, flickering light illuminating the stairway to be somewhat eerie for the first time since he moved here.
It was a dumb thought and he knew it, however, he still glanced around behind him before speeding up, taking the steps two at a time.
It definitely made him glad that he'd walked with everyone else at the very least.
He finally made his way into the small apartment, immediately heading to bed and flopping down on top of the sheets with a sigh.
He just needed to sleep, then these thoughts of Satoshi going into heat would disappear.
With some effort, he dragged himself back up, heading towards the bathroom to have a quick shower before practically sleepwalking to bed and falling into a restless sleep.
