Halloween, a holiday that has been called many things by many people over the centuries All Hallows Eve, Samhain, and even Nightmare Night. Each of these describes a night when children dress up in costume and get candy from their friends and Neighbors. but there is an even deeper and older belief that comes around this time of the year.

This belief is that Halloween is the night when the barrier between other worlds is at its thinnest and many can cross over from their worlds to ours and from our world to theirs. This is the story of two people that with the help of a god crossed over into another on this night and became Heroes demons yes but Heroes all the same.

“Man I’ve really been looking forward to tonight,” A tall man with long black hair brown eyes and wearing a black suit with a red tie and white dress shirt with a long flowing black trench coat. “With that stupid virus we never got to go to any cons this year but at least we get Halloween.” He looked at his companion.

"Good news is they're having a convention here in town for Halloween we're making up for everything we missed because of that virus." The well endowed young hermaphroditic woman said her long blond hair bleached and dyed a light blue she was wearing a long blue jacket with ruffled blue faux fur on the ends of the sleeves, a long white faux fur scarf, short baggy black pants, blue boots with blue faux fur on the top and a katana with a gold tsuba and pommel black rapping on the handle and navy blue crystal hanging off the pommel sheathed on her back. "I'm glad we can use our cosplay tonight so that we can test it out for the con tomorrow."

“Yea, and we can always go tomorrow and get half-price Halloween candy,” The tall man gave a thumbs up. He pulled a pack of candy cigarettes and took one out and placed it in the corner of his mouth to complete his costume. “Good thing these are abundant no matter the time of year.”

The two friends separated to do their trick or treating, the woman arriving at an odd building next to the convention center. "Seems the host got into the spirit of the season and gave us a haunted house the pass through." She said reading the sign next to the entrance "convention preview haunted house. at the end, you can take whatever you want from the candy bowl or up to 6 items from the mannequins in the house itself as these are free samples given to us by Merchants to use for this year's event from their extra stock unsold due to the Coronavirus"

"Neat this sounds like a fun time." She said as she entered. Instead of a single hall full of half scary mannequins, there were three choices from the lobby: the first Hall had scary folklore creatures above its door, the second had scary things from the internet above its door, the Third had scary video game monsters throughout history above its door. As the young woman was an avid gamer see the side to go through the door all about video game monsters hoping that she could get some neat merch for free.

Inside she saw many different monsters from popular video games aberrant Rockwell with his implant hanging above him from Ark survival evolved the deathclaw hunting down a Vault dweller from Fallout 4 and 76 so you could tell it was modded by the version of the deathclaw that was there as it had noticeable female features the cyberdemon running from the Doom Slayer in his Undead armor from Doom eternal at the end she saw a man wearing nothing but a white bodysuit covering everything including his face the odd thing about him was that scene that his body was outlined in black dots possibly visual effect from the lights in the hallway knowing who this was through popular culture she decided to talk to him as if he were the real Truth.

"Hello, sir. What brings such a being as you here on All Hallows Eve? Is it that due to the weakened barriers you come through to observe the normal Man without having to worry about warping reality due to your very presence?" She asked.

"Quite right," the man said, his face devoid of features, even the inside of his mouth painted white she thought. "So do you choose to get an item or candy depending on what you choose you might find something interesting happening later.

"I like the armor of the Doom Slayer but I don't like the fact that the mask is broken do you have one that's completely sealed for replacement purposes cuz other than that I'm thinking of grabbing the Pip-Boy there the Rockwell implant which I hope is the max level for the whole of Ark with all the blueprints unlocked." She said a smile on her face.

"Good choice Miss- I'm sorry you never give me your name I usually ask for that when people are taking from the stock." He said

"Ayumi I guess it's for posterity reasons and I'm going to have to sign something to keep the merch instead of paying." The woman now named Ayumi said.

"More for the list of people that have taken things you don't have to sign anything. I just need your name so that we can know what we're replacing and yes there is a full helmet for you to take. It's an integrated Google Glass helmet allowing you to sync your smartphone with it. While we do have the version for the undead armor that was a broken helmet that looked even better than the one from the undead armor so I used the broken helmet instead as it looks better." He wrote a note down in a notebook. "Just letting you know both of those props the implant and Pip-Boy are from modded versions of Ark and Fallout as you can tell from the obvious boobs on the deathclaw and the different coloring of the aberrant Rockwell." He said as Ayumi grabbed the Pip-Boy and implant. " Here take this," He said, handing over the helmet of the Doom Slayer the visor unbroken. "This is modded too but I have no idea what was added." With that Ayumi left and the hall shifted.

Where there was once the Doom Slayer and a Cyberdemon now there was Dante in his sin Devil Trigger mode holding his blade against Virgil in his full demonic form. Where the deathclaw and Vault dweller stood there was the black beast Ragna's blade in front of it, the large diorama with the aberrant Rockwell split into two. One holding a Medieval Chaos Gallantmon the other holding the main character from "How Not to Summon a Demon Lord". Both only there due to their placement and games and game-related media. This is what the Tall man saw as he entered.

“Neat stuff,” The tall man crunched the remnants of his candy and then grabbed another to replace it. He looked over the Demon Sword Dante and then over to the Blood Scythe Aramasa and then the Demon Lord’s Ring from how not to summon a Demon Lord. “No freaking way!” He walked over to a set of white, gold, and green set of full plate armor holding a dual-edge halberd. In overall appearance, it was very similar to Medieval Gallantmon but more sinister. “I’ve only ever seen this in fanart,” He pointed as he turned to Truth. The tall man felt drawn to all of the items before. “You’re one of those merchant guys that sells props that became real when people buy them and are sent across the omniverse aren’t you?”.

"Are you going to take some items or just some candy depending on your answer, something interesting might happen later." He said using his line from before. "The sign said it all." He added "The props were given to me by Merchants. I just run the haunted house. I get so much business through this hall that I usually stay here and have a motion detector alarm for the other two." He pointed to a door on the far wall. "If a signal is given from one of the other halls I just pass through this door to get to either one as there's another in the middle Hall that allows me to get to the far Hall. Now judging by your outfit I believe your friend just passed through here Ayumi was it?"

“Yea that’s her name,” The all man crunched his candy and swiftly replaced it with another piece from the box. “And I’d love to take these off your hands they’re sick as all hell,” he smirked, “Names Akira by the way,” He thumbed himself, “Let’s get started,” The tall man named Akira said cracking his knuckles and moved to the armor first.

Take one of the gauntlets from the armor he placed it on his right lower arm flexed the fingers allowing the armor to mold to his hand, Suddenly the rest of the armor flew from its place and covered Akira from head to toe and then retracted into the right hand’s middle finger in the form of a blue band. Next, he moved to the Demon Sword Dante Diorama and took hold of the blade. A swirl of hellish red and blue flames swirled from the diorama into Akira as he put strength into pulling the sword from its place. Soon he held the weapon in front of him with a wicked grin and held it above his head and transformed into a combined sin form of the devil brothers and dual-wielded the Vergil in his left hand and the Dante in his right. Placing both weapons on his back Akira reverted to his human form. “Now you:” he took the Demon Lord’s Ring and placed it on his left middle finger and his clothes changed to the form of Diablo from the novel while he retained his long hair but it turned white before he again regained his normal form. He never noticed that his eye color had changed from brown to black. Akira moved to the last item on the racks and put a hand on the handle of the scythe still in its sword mode pulling it from the stand. He merely thought it and effortlessly slashed the air and then threw it behind him and it extended into a scythe with a stream of crimson red liquid energy flowing from it into the form of a scythe. Akria effortlessly twirled this around before he reverted it to sword mode and placed it on his back.

Pulling a cigarette from his pocket Akira lit it with a gold lighter and took a slight drag on it then breathed out with a cloud of smoke. “Looks like it's my turn,” he spoke with the cigarette in the corner of his mouth and walked through the door after Ayumi.

"Hello there you two my name is John de Lancie," an older man in a black suit coat and jeans said as the Two exited the haunted house. "also known as Q also known as" in a flash of white light in the snap of a finger an anthro draconequus appeared "Discord! You may be wondering why I introduced myself by both my human name and the names of the characters that I am most famous for. Well as you should know I do not voice act my characters I am my characters Discord is my native equestrian form and I am Q in the future when humans are involved" He explained "I don't usually appear in this form on Earth but for tonight I'll make an exception since it's the equivalent of Nightmare Night. Add in the fact that we're having a cosplay party here I felt I should get into character." As he said this a girl in an eerily accurate anthro Fluttershy costume walked up to Discord.

"Discord are you bothering these two?" She asked her voice a spot-on replica of the character along with… other things.

"Not at all, dear Fluttershy." Discord said "In fact, I was welcoming them to the party. After all the more the merrier! Isn't that right Pinkie!"

"That's right Discord!" the pink party pony said as she bounced over here her curves and assets on full display just like Fluttershy's. "Happy Nightmare Night, hope you brought something sweet to bite!" She said to the female of the two newcomers giggling at her pun while the tall man simply stood there and smoked stoically.

“Nice to meet you, two lovely ladies. Names Akira, Akira Kunai,” he introduced himself nonchalantly as he pulled the cigarette from his mouth and tapped the butt of it with his thumb allowing the ash to fall to the ground where he then slightly tapped his foot on it to put out any lingering cinders. “Not to be rude or point out the obvious but why is everyone in the buff here?” he asked, placing the cigarette back in his mouth. “Candy cigarette?” Akira offered the party mare a box of his sweets.

"The party is late enough to be clothes optional!" Pinkie said, "Plus our hometown is a nudist colony our whole country is!" Pinkie said as she grabbed a candy cigarette and two cups and walked up to the newcomers. "You want some milk?"

"Sure I'm parched," Ayumi said.

"You go ahead, I'll have something a bit stronger," Akira said as a black portal opened and he reached in and pulled out a bottle of bourbon and unscrewed the cap, and poured himself a glass. "Anybody want some?"

"These clothes aren't for show you know!" Pinkie Pie said as she squeezed one of her breasts, milk coming out. "Rarity made them and Twilight Enchanted them so that they would allow me to serve milk without having to have a child." As she said this she filled both cups. "My boobs are getting heavy so you're both going to take the milk and you're going to like it!" She said as she passed the two demons their cups.

" I'll admit when you asked for cow-print I was surprised, Darling, but knowing what you are doing with the costume that I made you I definitely approve." Rarity said walking up to the party pony. "If you wouldn't mind Darling I would like a refill. The dancing has gotten me quite parched"

"Yeo, this world is going to take some getting used to but I'm already enjoying the benefits," Akira smirks as he downs his glass of bourbon and then enjoyed his milk. "Mmm… Not bad." He nodded then looked to Ayumi. "How are you taking all this?"

"Dude this is still earth," Ayumi said pointing out the skyscrapers in the distance with TV screens on them. "Discord has brought the girls to our world to enjoy a more adult Halloween party without the risk of getting in trouble in Ponyville."

"I do this now and again with the girls." Discord admitted, "surprisingly your friend is very observant for a slime."

"Well I'm only dressed like him I'm not going to turn into a blue slime," Ayumi said as she shrank into a blue blob-like slime. "Huh did you all get bigger? Discord!"

"This is all you Ayumi!" The draconequus said as the slime wobbled.

Aww, you're the cutest little thing ever!" Fluttershy squeed as she picked Ayumi up and held her on her chest. " So cute!" The caretaker nuzzled the slime.

"Adult party on earth or not! I'm going back to Equestria with them," Akira snickered at the sight. "Hot pony chicks in a nudist society in a world where you get awesome powers, why would I stay on earth? Not like I have a life outside the office and conning with you anyways." He finished his milk. "Good stuff this. So tell Ay, what about you?"

"I'm OK with this but I would like to visit Luna at some point." Ayumi said "The fact I'm a shapeshifter more diverse than a changeling is awesome. If I remember correctly I'm the blacklight virus in a cuter form."

"Blacklight what's that?" Came from behind Fluttershy "and who are you, Sir?"

Akira turned to see Twilight in a very revealing witches outfit. “Hello there my name is Akira Kunai and this is Ayumi Rimuru,” he motioned to the slime still being nuzzled by Fluttershy. “We were invited by Discord. As for the virus, the Blacklight virus, dubbed now as the Mercer Virus by the general public, is an evolutionary chimeric mutation-causing infectious agent that can reproduce only inside the living cells of other biological organisms. After infection, the virus "plugs in" and activates the 'junk' DNA in its victim, resulting in several biological changes that create (and recreate) sentience within the infected creature's cellular makeup. It acts by affecting the protein-encoding regions of the promoter introns in each cell. As a retrovirus, it contains both RNA and the reverse transcriptase enzyme, allowing it to insert its genetic codes into the host's cells. It enters, re-purposes, and changes the cell, replicating previously dormant non-coding segments of the organism's DNA. More often than not, these changes are too drastic and 99.99% of all infected organisms die from massive organ failure and cell saturation. However, few variants have yielded other beneficial results, endowing the infected organisms with incredible superhuman genetic prowess that greatly increase their natural abilities to levels far exceeding human capability. It allows one to mimic almost anything like blades and stuff,” Akira explained to the book pony. “But Ayumi doesn’t have the virus but an ability that does the same thing but first she has to eat whatever she wants to mimic.”

"Not necessarily the whole thing though it's just that the character that my power comes from did eat the whole thing almost every time due to it being a threat to the character or others around it." Ayumi said her voice vibrating Fluttershy's breasts due to her semi-solid body "The ability also works with dead tissue as he ate the corpse of a human to regain his human form after she had died from intense burns. This may allow me to take a feather or a piece of mane and use it to replicate a whole being, as well since they are also dead tissue. It has never been tried by the character my costume was based off of but if you're willing to spare a feather or a lock of mane I would like to try it so that I can experience Life as a pony at least once."

"Wow," Twilight said, "if what you're saying is true you could even combine traces of other creatures with yourself make yourself stronger or create a whole new being!" As she said this the rest of the Mane 6 Barb the dragon Sunset and Starlight approached.

“Oh, yea the original Rimuru was able to do that no sweat,” Akira waved off the comment. “Hello ladies,” he gave a half bow.

“Who are your friends Twi?” Sunset asked looking over the tall man and then to the little blue slime poking out from under Fluttershy’s chest. “Is Shy trying to suffocate an animal with love again?” She snarked.

"I'll let you know I am mostly liquid so I can't suffocate!" Ayumi shouted as she kept from Fluttershy's chest and reformed herself into her human shape sans clothes. "Besides she's warm and I like warm things."

“You also like being buried in boobs,” Akira chuckled. “Allow me to introduce us again, names Akira Kunai and the one that was buried under mounds of fleshy goodness is Ayumi Rimuru,” Akira motioned, causing Fluttershy’s face to redden from the compliment.

"Can you blame me I mean look at me I'm both male and female that is utterly confusing!" Ayumi said, gesturing to her body. "Add to that I'm now a semi-solid slime who can be frozen easier than before. That means I'm far more sensitive to temperature now even with the elemental resistance the original Rimuru had." A sudden breeze caused Ayumi to shiver making her realize she was nude. "Dammit." She grumbled as her clothes formed over her.

"Darling your outfit is simply divine!" Rarity said "And the way you summon it seems very useful! I wish I could change that fast and fluidly!"

"That would also cut down on my load when we travel." Barb said "And Ayumi I know exactly how you feel. I'm also male and female at the same time. it is so confusing."

“Male female, or both,” Akira sighed as he pulled out another cigarette and let it. “Would it matter as long as you’re you Ay. Equestria is a land of acceptance, I mean they’re a freaking nudist society, so I don’t think you have much to worry about. Like Barb here, I bet all dragons can change genders if they want to, up to a certain age I’m guessing, but I’m just taking a shot in the dark here, hell if I said I’d do ya. Would that help, I mean you're hot as fuck!”

"While you're right about the ability to change gender at will due to how long we live we can do it as long as we live." Barb replied "Normally dragons will induce a molt to change their gender when they're below viable production for children. Whether it be male or female. I'm a rare case of being able to be both at the same time due to my unique circumstances of birth. Along with the two dick thing that isn't natural for every dragon about 30% of male dragons have two."

“Ah’m with your friend there sweetheart,” Applejack added. “The best kind of honesty is bein who ya are and if you're both then be both. Wann buck a mare buck than buck a mare, wanna do a dirty deed with a stallion then do it,” She crossed her arms under her chest forcing her boobs up, “Same goes for if you wanna have both at one time. I’m just sayin be who ya want and no pony will fault ya for it.”

"If you want you can take me right here and now!" Rainbow Dash said as she bent over exposing her already soaking pussy. "Just warning you I'll have you cumming in 10 seconds flat."

“Here’s your chance Ay,” Akira pointed to his friend. “Too bad I don't have a camera, well, Discord does for some reason,” he let out a cloud of smoke from his mouth looking at the chaos spirit. “Well, what ya say?”

"Not tonight." Ayumi said "I don't want to risk giving Rainbow Dash a child and not being there to care for it afterward since we're still on Earth. With how wet she is it's obvious that she's in heat and if I try anything tonight I can almost guarantee I'd be giving her a kid." She then turned to the presenting Pegasus. "No offense but if you weren't in heat I might have taken you up on that offer."

"None taken." Rainbow Dash said. "You're right I am in heat and to be honest I'm not ready for kids yet I still have to take care of my little sister Scootaloo. Though I thought since you were a slime it would not take. Then again if you're from another world who knows what could happen better safe than sorry."

"I'm only partially a slime. I'm a Demon Lord as well if I remember correctly. Though I only recently became one." Ayumi said, "Since I'm a Demon Lord it's more than likely my demon physiology will take precedence and give you a child through the properties of a succubus."

"We both Dodged the bullet then because yeah no offense I really am not ready for a kid!" Dashie said. "Thank you."

"You're a demon?" Starlight said as she shifted her G-string. "You're way too cute to even be an imp!"

"Akira is a mature Demon Lord and far stronger in that regard than I am. One of his titles is Lucifer, king of hell," Ayumi said. So ya believe me when I say that we are pretty strong."

All of the girls immediately turned to look at the tall smoking demon lord, “Somehow Ah find that more believable but still don’t believe it entirely.”

"If Thou art the king of Hell may you please command your denizens to stop intruding Upon Our Land," a regal voice said from above. "While most are easy to destroy some have caused the Great numbers of casualties amongst our guards."

“Sorry, Princess but I don’t rule Hell, at least not the hell you know,” Akira bellows smoke in the air. “It’s simply at title I when I gained my current form,” he looked at Princess Luna. “Noce costume.” Akira pointed at her. She was wearing mostly white arm and leg covers and pink see-through top and pants.

“This is my casual wear,” Luna shot a glare back at the demon lord who didn’t even flinch but shrugged.

“Hey you’re all hotter than sin and you’re wearing the minimalist clothing that shows off your bodies,” Akira said talking the cigarette from his mouth. “No one back home would have the balls to call it casual wear, and if that’s casual I can’t wait to see what you look like in regalia. Seriously, I’d be lucky for a one night stand with any of you girls,” He snickered. “But at the same time, I’m not just gonna say outright’ let’s bang’ and be gone forever. Not that kind of guy. Where’s your sister at by the way? I want to make sure it's okay to come home with you girls.”

"The Crusaders were taken home by my sister and I," another more motherly voice said, "while they are old enough it is getting late and they aren't allowed alcoholic drinks past 11."

"I take it alcoholic drinks are more for those that have an actual job instead of those that only get an allowance?" Ayumi said to Celestia who was wearing a see-through bed sheet with holes for her horn and eyes, her golden necklace, and nothing else. "Okay I may be a Demon Lord but you are too much of a succubus when dressed like that!" Ayumi said, eyeing the visible milk trails from Celestia's nipples. "I see where Pinkie got her idea from."

Celestia looked to where Ayumi's eyeline was pointing to noticing that she was leaking. "Well as a fertility goddess it does happen to me quite often." She said candidly.

“If you’re gonna oggle that much, ask her to play seven minutes in heaven or at least go in the other room,” Akira rolled his eyes. “I honestly can’t make up my mind who to stare at right now.” he tossed his cigarette but on the ground and stomped on it. “I’ll even give ya a couple of these bad boys to go a couple of rounds with her,” He held out his cigarette carton. “And before any smartass says they're bad for you no they’re not harmful these help you regain vitality. So yea, light one of this up and you can go in the sack for however long your stamina lasts. Any takers?”

“Ah find that hard ta believe but Ah know ya ain’t lyin either,” Applejack took one and Akira lit it with his lighter, Taking a long drag on the Cigarette Aj let two streams of smoke come out her nostrils. “Not bad. Ah, do feel like I could go a couple of rounds in the hay. Maybe Ah should save the rest for working at the farm.”

"Darling you should use a holder for your cigarette to make it last longer." Rarity said as she pulled her pack out and her holder inserting one of her hand wrapped variety before lighting it and puffing on it. "These are my handmade creations; they have the same effects and are what allow me to go all night with my work. Zecora just supplies me with the herb that I make these out of."

“No offense Rars but Ah prefer this way better,” Aj took another hit from her smoke. “All that fru fur stuff ain’t mah style and ya should know that by now.,” She crossed her arms showing off her breast again.

“Are these two always like this?” Akira whispered to Pinkie.

"Only when they're not fucking!" Pinkie replied cheerfully. "All of us are casual fuck buddies, even Princess Luna and Princess Celestia. That's the other reason why the Crusaders were sent home. So that they can have their own little snuggle party. Especially with Apple Bloom being almost as big as Big Mac!"

“Wow, you ponies sure aren’t shy about the whole fuck buddy ordeal are you?” Akira deadpanned. “Does your world have mass orgies in town sometimes?” He joked.

"Not necessarily outside." Celestia said. " ever since the gigantopithecus raid of 840 BNM "rural towns have had a dedicated orgy Hall. A massive building with multiple large bedrooms allowing for parties and orgies of any kind. Cities like Manhattan and Canterlot have large walls that keep out any predators that could either kill or kidnap other people. Allowing the city to have public orgies."

“I’m no sex addict but your world keeps sounding better and better to me,” Akira closed his eye switch a snicker. “Would you both say about letting me and Ay come over to your world? We can help with the demons and stuff if you want.” He offered. “I wouldn’t mind going a couple of rounds in the sack with you guys either. Up to you though, “Ahira shrugged.

“You are in luck Akira,” Luna smirked evilly. “Because we are already in our world, Manhattan to be precise.” Suddenly the walls and everything around then cracked and shattered like glass.

“Cool,” Akria remarked as he lit another cigarette. “Hey Ay, told ya so!”

"We're not home?" Ayumi said as she shrank back into her slime form. "No! I refuse to accept it!" She shouted as she turned to Discord "YOU! TAKE ME BACK!" As she said this she transformed into her dragon for smoke billowing from her jaw. "TAKE ME HOME NOW!!!!!"

"Not dealing with this!" The Chaos spirit said as she smacked her on the head knocking her out. "When she wakes up I'll talk to her."

Akira was suddenly behind Discord...
