Sin Underhell Chapter One
“The Fallen Human” There’s a body on the ground, lying with a bloody baseball bat lodged in its skull, its butt end pointing up towards the blood red as if it were the bloody sword of legend inviting anyone to draw it from its proverbial stone. A hand takes a firm grip of its handle and starts pulling the bat free. This was the hand of a mortal, one named Frisk. A Japanese non binary child at least 11 years of age standing about 4 feet or so tall, brown short hair in messy anime protagonist cut that slightly covers their eyes. Garbed in a blue hoodie rain jacket with pink stripes and pink forearm sleeves, it is a bit baggy with the sleeve holes slightly being too big to cover the arms. Jean blue pants, chocolate gray sneakers, a pendant around their neck in the shape of a red heart. The expression on their face is pure wide awake fear and exhaustion, they have not had a chance to clean some of the dirt on their clothes.
They’ve been here since October 31st 2026, 6:06 A.M. It is now three days later, November 2nd 2026 7:28 A.M. And when they first got here, how much they desperately wished this was but a final dream, the final synapses of a dying mind envisioning this final nightmare before oblivion takes hold. How they prayed that there is no God, no afterlife, for no other reason than to find solace that this wasn’t their new cold hard reality. This was no dream. This is Hell, straight, up. What else could this place be but the home for infinite losers? The asshole of the universe? How they would have gladly accepted non existence over the existential nightmare that lies before them. The horror. THE HORROR. They are forced to embrace it.
They had dislodge that bat from the course, about the fifth of sixth time they managed to get a hold of a weapon. Hopefully this one will last longer. But it’s made of wood, sturdy as it is its longevity is already in question, especially with these damn screws bored into its top end binding some barb wire to its surface. Oh sure they will help make this weapon more deadly but closer inspection shows that the bored screws have caused small cracks in the wood mass. Frisk starts walking away….but then……that dead body’s one eye suddenly rolls in the socket.
Formerly Dead Demon; “Wh…..wha……where am I……?”
It was a voice with a soft echo like reverb, just like every other voice Frisk has heard from every other creature in this place.
Formerly Dead Demon; “How….long was I out…? Oh fucking great my arm’s missing…oh there it is……”
Guess this demon was only dead because of the bat lodged in their brain cutting off a crucial synapse. The demon was barely able to crawl about with his fractured leg, dragging himself towards where his severed arm was, pressing it against his stump of a shoulder it started to….well, “regenerate” wouldn’t be entirely accurate, more like mutating like cancer cells becoming like biological duct tape. Same with the gaping hole in his head where the bat was, his biology doing what it can to fill it back up with new flesh, doing a rather mediocre job growing back his missing eye as it didn’t even match the other one. It’s impressive that his motor functions are able to be restored to his arm. Frisk isn’t even surprised anymore, this is but the umpteenth time they have seen this kind of thing happen. Frisk didn’t even bother to look back at it happen much less stop walking away.
Formerly Dead Demon; “Hey you! HEY! I need a fresh new leg! I got 2/5th of a prostitute’s soul, gimme one of your legs and you can have that 2/5th!”
Frisk just kept walking. Furious that he was being ignored he grabs the pistol closest to him and points it at Frisk.
Formerly Dead Demon; “Bitch I know you can fucking hear me! Either give me your leg for some soul or I’ll take it for free!”
Frisk just kept walking. At which point the demon pulls the trigger….nothing. He discards that pistol and grabs another, it was also empty. Frisk just kept walking, holding that bat in between his arm and side of chest allowing them to use both hands, loading a pistol they have with some of the collected bullets just loosely jingling in their jacket pocket. Good thing they scavenged for those first. The demon was quite persistent, even with a useless leg dragging him down he is putting as much effort into his arm muscles as he can muster. Though Frisk just kept walking, they were taking a firm grip of their pistol. And when it sounded like the demon was within spitting distance about seven feet, Frisk quickly turns and takes aim right at the incoming demon’s head. A single bullet was all it took to make him a corpse again……not that he will stay that way for long. And then the minute they heard a familiar roar, this dead guy became the last thing on their mind in this micro instant. It was the roar of something BIG, something that was both monster of flesh and large mechanical machine. There might have been a thought of pity spared to pulling this poor bastard to safety, Frisk even grabbing onto one of his arms to pull him off, but that roar was now even louder. In fact, they spotted a great big shadow out of the corner of their eye, looking to see something flying in the immediate air space about half a block away. It wasn’t looking this way, yet. Frisk just started to book it to the nearest dilapidated building , ducking behind what was left of a damaged receptionist front desk. Sure enough that dead demon came back to life, letting off a most frustrated agitated howl as he got back up off the ground, practically pushing the bullet out of his own head as if popping a zit. Alas, this fit of anger immediately bites him in the ass, a sudden giant shadow looming over the ground is all the warning he gets for what is about to happen to him…… It had teeth, massive teeth of glowing blue steel that shimmered with electrical discharge, these teeth digging into the very ground taking that demon and about a good chunk of the ground in but a single bite. The manner in which it consumed that scooped up debris was nothing short of messy haste, ravenous and greedy intake as if it hadn’t been properly feed in days, messy crumbs spilling from the sides of its lips. The rest of it was indeed what its roar implied, flesh and machine melded into a chaotic amalgamation of matter. The base form was that of ancient beast of the sea from millions of years, traits of a shark and an electric eel punctuated by the biomechanical nature to fear inducing extremes, hovering in mid air it was completely unbound by the very concept of gravity. Five eyes burning with crimson red glow, four of them lining the sides of its upper head, the fifth most prominent eye upon its snout as if it were the lens of a video camera gazing forward. There was no nose that could be seen but it could still smell, as made all too evident by the slight upward scrunching of its face and the heavy sound of nostril breathing. It just floated there, silent….before suddenly just attacking that very building Frisk ducked into, its very mass all but melting the building into crumbling dust and debris chucks upon impact.
Frisk; “SHIIIIIIT!”
Frisk was already out the back door by the time the building was erased, but they could not stop moving, ducking into another nearby building just as the great beast was peaking its nose out the other side. It didn’t even need to have seen Frisk know they were in there, just punching right into it causing it to start collapsing. Having to double back out of there Frisk ran right into the building next door. For the moment the massive clouds of dust hampered the beast’s smell, but it could still see with sight of infrared, but there was much interference as there were several heat signatures abound inside. The beast began to circle the structure
Frisk was indeed not alone, Of all the buildings Frisk had to duck into this one had to be full of….children. Sleeping children, none of which were even remotely human. Laid bare with not one article of clothing ale green putrid skin almost black as obsidian, The smell was musty and strong, like rotted wood left in an abandoned mil for decades. What details Frisk could gleam of their bodies showed they were more animal than humanoid, fingers bearing large claws from the fingertips. Many were sleeping next to bones picked clean of all meat and sinew. Many were huddled in piles within the individual rooms like worms in a nest. There was no point checking these rooms for supplies, there was only going through the main halls, going to high ground. The stairway was right over there, just had to ascend up to it. It was about a good ten minutes, ten exhausting minutes of dealing with the lingering smell of the defiled remains of unlucky souls scattered here or there along the ascending flights. And then there was the door to the roof. Slowly opening it Frisk peaks through the open slit. They spot what looks to be shark fins passing along the edge of the building.
Frisk; “Oh goddamn.”
That damn shark beast was still circling the building trying to get a whiff of its intended prey. All it could see is all the sleeping creatures in the floors below. By some miracle Frisk was able to sneak to the edge, better assessing just how royally fucked they were. The beast was not so close to the roof anymore, swimming through the air a little lower. Welp, time for a Hail Mary Pass. Frisk reaches into their pocket, pulling out a basic looking grenade, one of the only two they had with them. Such a waste to even pull the pin but they needed something, anything, to draw the beast’s focus away. And so they chuck that grenade as hard as they can down towards the city streets below, it goes a good 100 feet before exploding. And as hoped the beast took notice and started to move towards that direction…..but as it does its tail ends up cutting into the side of the building, this brittle building that was pretty run down already barely holding together. Now it was starting to lean over falling like a chopped tree. Not knowing what to do Frisk just ducks back into the stairway corridor and shuts the door, pressing themself against the wall and praying they make it out of this...
The building comes crashing down all over another abandoned structure, a flimsy rotted parking lot that might as well have been made out playing cards. Made the collapse drag out a little longer that it would have.
__________________________________________________
Miracles of miracles, that rooftop entrance survived, snapped off the rest of the building and tumbled like a stone onto solid ground. Though Frisk wasn’t exactly sighing with relief, what with all the damn dust getting in their lungs and the aching pain from being rattled around whilst hanging onto the stairway railing. Their grip barely holds as they just drop onto the one wall, well, a wall that is now just the floor. Frisk ignores the pain and forces themself off the ground, walking through the big gaping how that used to be the stair way down. Upon exiting the rooftop entrance, they better see the damage, the entire building they walked into is just rubble spilled upon the city block like a pile of sand and debris. Well, hopefully with the building’s collapse all those things were crushed like bugs, one less problem to worry about...
But then as they started to walk down a nearby path, Frisk can hear it, the violent breathing of something looking right at them from above. Slowly turning, there it was, one of those hideous children, fully awake with burning green eyes glaring like a rabid animal. Squatting upon the edge of a piece of debris being ready to pounce at a moment’s notice. Frisk needs to get out of here, if one is awake, so too must the others. No sudden movements now, gotta get the bat ready, gotta.....gotta start moving back. Slowly....slowly....no sudden movements. The little freak lets out a blood chilling shriek, leaping into the air right towards Frisk. One side step is at it takes to dodge its pounce, after that Frisk then readies their bat and takes a hard swing at its head. Splits open like a spoiled melon, blackened viscera plopping upon the ground with a winch inducing thud. To think that something so vicious is so fragile.....but of course if one isn’t much trouble...... Frisk; “Fuck.”
Many of them will be a serious problem, as the sudden screaming coming from afar can attest. Frisk did not bother to wait until they were in view to start running, they knew all of them were on their tail, they just had to move. NOW. Using all the strength in their legs they can muster they navigate the torn uneven There’s a loose tank with some kind of emblem, whatever is inside is clearly flammable. All it would take is a slight tug to pull it off its flimsy wood rack. Frisk has only moments to spare, grabbing it and pulling it as hard as they can, getting it to tumble and roll across the floor.....just as those little black freaks were turning the corner into that alleyway. Slightly skipping to keep momentum Frisk turns backwards and takes aim, hitting that tank square in the side. It does nothing and those damn children just run around it, wasted a bullet. Frisk turns away to keep on running....but then a flame erupts from the hole in the tank. Boom. Several of them go flying about, the closest get torn asunder from the blast. But it is barely enough to thin the herd. Frisk is only focused on running, turning a corner and heading into another alleyway. Several of those damn thing manage to catch up, scaling the walls trying to outflank Frisk. One leaps down managing to get up onto Frisk’s back ready to slice at their face, only to get a bullet square between the eyes. Pulling the thing off their back they then toss it at a nearby fire escape ladder causing it to drop down. It took so much that Frisk had to quickly climb up faster than these things could climb the walls. These things were already swarming the fire escape, giving Frisk no choice but to just shoot their way into a nearby window.
Right away they come across a bedroom that wreaks of blood and feminine product, a truly rancid smell indicative of the very macabre sight now before them. A male demon chained and crucified to a wall, missing the lower half of his body with much of his entrails and organs hanging out. Systematically being torn apart by two cannibalistic succubus imps in dominatrix outfits eating pieces of him, nearby another succubus imp is sitting in a chair with a video camera in on hand and her inner self in the other.
Half Mutilated Demon; “Do you fucking mind mate?!”
Frisk; “Uhhh, sorry, wrong house.”
Camera Succubus Imp; “If you’re looking for the onii-chan rolepay room it’s down the hall to the left, number 108.”
Frisk; “........riiiiiight.”
Quickly Frisk makes a break for the door and shoots at the lock, just as those zombie children start pouring into the room. Right away the succubi just bolt out of the apartment leaving their client behind. Half Mutilated Demon; “HEY WHAT THE SHIT?! AT LEAST GIMME MY MONEY BACK!”
Many of the demonic children stayed to pick apart what was left of him. The rest flooded the halls going right after Frisk and anything else that moved. It was a stupid idea to go into the elevator indeed but Frisk just stopped thinking, running on instinct and impulse as they mashed the bottom floor button and blasting any demon child that got close. Many of them were cut in half by the closing doors, but even the severed halves just kept swiping their claws at Frisk forcing them to stomp down on the little freaks’ frail heads. In what brief moment of respite this elevator offers Frisk checks what ammo they have left, only enough for one full 9-round clip. Great.
As the elevator reaches the bottom floor, Frisk stumbles out of the doorway before it fully opens, not wanting to waste another moment in this infested building. It takes a bit to regain their footing as they bolt out the front door. It doesn’t take very long for those little fuckers to start coming out of the building right after Frisk, smashing through the windows and the external ventilation shafts. Some of them were quite spry on their feet, driving Frisk to pop them wasting precious rounds. Reduced to just one round there was no point using the gun. One of those freaks comes close, Frisk takes a swing and manages to cleave it in two. Another gets close and suffers the same. One after another Frisk swings that bat with all their might. Soon many of the hellish children were starting to circle around, surrounding Frisk. Frisk tries to keep it together, keep on fighting, keep on smashing the ever living shit out of every one of these little fuckers that dares to get closer......yet it seems these little freaks are now starting to toy with Frisk trying to bait them into a vulnerable spot. And as Frisk starts to breathe more heavily, they wonder how much longer they can keep this up. But then, a voice spoke from behind.
Charlie Morningstar; “ENOUGH.”
It was a feminine voice, no, two voices speaking in perfect unison producing a slight echo distortion. One was a secondary voice, a near faint whispering tone one could describe as Galadriel ASMR. The other was the primary voice, firm and resolute in tone, a regal figure laying down their authority with but a single word. And these demonic children imps could not ignore, great fear in their eyes as they stood there like deer in headlights. One by one these demon children started to crawl away, cowering back to the nearby shadows. Seeing this display happen, Frisk was just as scared, especially when they felt a hand touch upon their shoulder. A bleach white hand with only four digits, black fingernails like claws. Charlie Morningstar; “Are you alright?”
It was the same distorted voice, speaking more kindly than before. But Frisk was too afraid to even look back, too afraid to move so much as a muscle……so this voice, this being decided to walk around Frisk to the front and lean down looking them in the eye.
Charlie Morningstar; “Hello there.”
She was a demon for sure, a somewhat towering 7 feet tall demon, one trying to pass off as anything but with her kind looking face. Bleach white skin splashed with rosey cheeks that look painted on like a clown. Golden hair that shimmered with starlight. A small black nose dotting the center of her face. Lips covered with black giving a soft small smile that showed some of her razor sharp teeth, honest to God she had goddamn razor sharp teeth. And then there were her eyes, rather massive animated character eyes that gave off the impression her skull mass was a good thirty percent eye sockets to accommodate these massive orbs. And they literally glowed, the golden yellow sclera practically LCD floods of organic matter. Her opal shaped irises were just as bright, crimson red, and there were multiple pupils like a goat….no wait, no, a goat only has two pupils in their eyes. She had three! Three pupils in a triangle formation. Her attire was rather formal yet alluring. A tailored carmine red woman’s suit, a particular ensemble that is predominantly a pants and a vest made as a single piece, transparent material sleeves from the shoulder to the cloth cuffs around the wrists, a predominant amount of exposed cleavage that conveyed a tasteful amount of playful allure. A carmine red jacket matching her outfit rested upon her shoulders like a short cape, held in place by a connecting chain of small golden pearls. A simple belt with a golden valentine heart buckle with the carved details of a grimacing skull.
Charlie Morningstar; “Are you alright little one? Need anything? A snack, a drink, medical attention, a shoulder to cry on?” She was beautiful yes, looked beautiful, dressed beautiful, gave off the very aura of beauty. And yet there was still just enough bestial traits that such beauty couldn’t hide. Those creepy eyes, those goddamn teeth, that distorted voice. And less we forget, those gremlins were terrified at the very sight of her. Frisk could barely move, no sudden movements, just one leg slowly back, then the other…
Frisk;
“N-no I’m…..I’m okay…..thank you.”
Charlie Morningstar; “Something wrong?”
Frisk; “N-no it’s just……I…….I…….”
And then suddenly Frisk just turns and runs away. Just starts running as fast as they can. Their primal self preservation overriding their cognitive thought, driving all the motor functions of their entire body. She was just being nice, she was helping them out……but they had to get away from her. There was something about her, something fake, deceiving, like a predator pretending to be fellow prey. So down the street they ran as fast as their legs could take them.
Down the street, just gotta get away. They were so desperate to get away they paid no mind to where they were running, incidentally running up a stairway that actually spiraled like a corkscrew loop, going upside down defying all laws of gravity. They were too scared to even notice, too scared to pay attention to where they are going. And then they come across it, a gothic looking train car, one looking like the centennial monorail system devised by General Roy Stone reinterpreted as a satanic piece of machinery pulled right off a heavy metal CD cover. Abandoned and up for grabs, no one was there to stop Frisk from finding the controls and starting up the machinery. Instead of steam there was a literal bleeding heart that was dripping with blood, metal spikes puncturing it to draw said blood to spill upon the engine below causing it to come alive with mechanical function. The small train car starts moving along the track, Frisk is on their way to…..anywhere else but here….and then Frisk sees her. That strange woman is just walking up to the end of the monorail platform. She stands there, looking right at Frisk, smiling, even waving. Frisk can barely look at her, dropping to the floor of the train car and covering their head.
Frisk; “Jesus hates me this I know….”
____________________________________________________
It is about twenty minutes later. Twenty minutes just sitting her in this slow as dying monorail train car that seems to be going nowhere. Sitting here all alone. Maybe they were just better off going with that strange woman? But......she just......no point dwelling on it now, they made their choice. Must keep going forward....
Frisk then hears something alarming, the sound of several feet of track getting trashed by a large object. By the time Frisk got up off the floor to see what it was they are now looking towards the open maw of that damn giant shark beast. The train car was already about three fourths of the way down its throat by the time those teeth clamped down. Frisk quickly gets near the back of the car away from the gnashing teeth, and before them was a true horrifying sight. The deeper innards of the monster is but one long mess of machinery designed for one purpose, grinding meat. Touch any part of it and Frisk will die. Simple as that. In desperation Frisk pulls out their pistol and tries to find something that looks vulnerable and vital, spotting some tubes with flowing liquids. Cross your fingers. A couple bullets and it punctures through, fluids leaking out and spilling all over these internal gears and clockwork. There is a pause in the beast’s gnashing and a loud roar of anguish. Last grenade Frisk has on them, pulling the pin and chucking it they then run back into the car ducking behind a steel wall…… Frisk; “For this bullshit tells me so….”
One internal explosion later, the beast is now experiencing severe indigestion forcing it to just spit that whole monorail train car back out. And like that Frisk was in free fall inside this metal coffin, trying desperate to brace themself for impact. They....they don’t think they will survive....
What happens next takes course over the span of 12 seconds, nearly too fast for Frisk to fully comprehend. Something, someone, punches right through the metal wall. She quickly goes right for Frisk and grabs them hold holding them close to her body as if they were welded to her. Moving backwards she shoves herself out of the train car, tumbling uncontrollably through the air towards a nearby building. Before impact, her jacket cape undergoes instant metamorphosis into about six seraphim wings that then wrap around the two of them forming a cocoon of feathers. This cocoon crashes into the side of the building, punching right through and out the other side, falling towards the city streets below. And then it just stops...
____________________________________________________
It was dark inside, just, damn near black. Frisk can’t even move, whatever it is they are lying on is holding them in place....arms, human like arms. They can feel their face pressing against a human bosom. She was warm, gentle. It felt nice just to have her arms wrapped around them. And then, her eyes opened and were now looking down right at Frisk, those same unnatural eyes. They glowed in this darkness, the only light in this enclosed space.
Charlie Morningstar; “Are you alright?”
Frisk is feeling quite anxious being this close to her, this thing that even other monsters fear. Frisk; “W....why...why do you care?”
She just smiled softly with a warm kind look in her eyes. Charlie Morningstar; “Why not?”
On the outside, the wing cocoon is resting in a somewhat large crater maybe 50 feet in radius. Whatever pavement was there is reduced to rubble and black dust leaving a huge gap in the rock beneath it, broken pipes spewing red water protrude out of the rock wall like severed arteries. It is pretty deep to be sure....but not so deep that the flying beast cannot fly down and gobble up as much of the ground the cocoon rested on as it can. Rising back into the air it starts to viciously chew all that it took in...only for something to come smashing out of its teeth like a bullet train. Something big, something long, something obsidian like a shadow. Coiling towards the blood red sky before then looping right back downward towards the now writhing shark beast. This shadow punches right through the spinal column, going all the way through out the belly. And once more it coils upward, looping right towards the shark beast’s left side and punching out of the right side. One coiling loop after another, punching through the shark beast again and again, a terrifying sight to behold the way this shadow starts to form an enclosing knot around its prey. And then at last, the final crunch, the shark beast letting out one last howl before it expires. And as it is snuffed of all life so too is the state of anti gravity keeping its body afloat. As such the shadowy knot drops to the ground with a rancid sloppy plop of slithering mass, upon the ruined earth it shifts and wiggles around and within itself like a nest of worms. And then from the constantly coiling mass, a head reveals itself from an opening of pitch black. An obsidian cobra with small glaring eyes of crimson red, a “crown” of glowing flames hovering right above its head, slowly sliding across the ruined earth towards the upper edge up onto the street pavement. About 50 feet it slithers forth before stopping, raising its head up about 12 feet off the ground and pointing its snout straight down, its mouth slowly opening allowing that woman to slide out of its throat, Frisk tightly clutched in her arms practically bleach white from just haven been inside another belly of another beast.
Charlie Morningstar; “It’s alright little one, you’re safe now.”
She kneels down gently letting the scared child sit upon solid stable ground. Standing back up she faces the serpent, placing a hand up its snout affectionately, gently pressing her forehead against its scaly skin. The serpent gives off an unnatural sound, purring like a mammal. The very idea of a snake able to display affection in such a manner...
Charlie Morningstar; “Oh Ouroboros, what would I do without you?”
This woman’s shadow stretched forth across the street pavement, expanding wide, just enough space for the serpent to enter head first. Within the next minute or so, about a good 2 miles of serpent mass slid forth plunging into the demon woman’s own shadow, quickly she could see its tail in view, a fin protruding from the end tip forming the vague shape of a kitchen knife blade. Once that end vanished, her shadow shrunk back down to match her own seven foot height. Turning around she sees Frisk is already trying to climbing some nearby rubble hoping to slip away. But it is quite lose ground and they are too silently panincked to get proper footing, the woman has all the time in the world to just walk up to them.
Charlie Morningstar; “I take it you have somewhere else to be? Prior engagements? Someone else in Hell who you’re suppose to meet?” Frisk ceased their pointless crawling up this mound of dirt and mud, slowly turning back to look at her. Frisk just stands there, hands dirtied and shoes half way stuck in mud, not sure what to even do. Still afraid, still shaken by what she is, what she is capable of. But still she offers kind words and an open hand. Charlie Morningstar; “I have a hotel, free food, a bed you can sleep in. And no one will try to hurt you. It’s a lot better than just wandering about this shit hole, aimless, alone.” Frisk is still afraid....still afraid of her.....but they would rather be in the presence of her than alone. And so they slowly reach for her hand and grasp it.
Charlie Morningstar; “What’s your name?”
Frisk; “Fr.....Frisk....”
Charlie Morningstar; “Charlie Morningstar, it’s a pleasure to meet you.” ______________________________________________
