It's been a while since I've last written anything about OG so it's about time, I did something about it.

Warnings: Mentioned violence (brief)

Ships: Color x Killer x Cross, Errormare, Horrodust, Dreamberry

Synopsis: "Killer, you're an adult." Nightmare glanced over said man with his single eye, not looking the least impressed, his arms crossed around his chest as if to defend himself from the wave of cringe he was the victim of. "Don't you think you're a bit too old for this?"

The bratty princess, as everyone liked to call Killer, gasped. "Too old for this?" He repeated, offended. "You're too old to be living!" He huffed, still holding the fake wand in his hand. "You clearly don't understand the Halloween vibe enough for a guy named Nightmare!"

"Killer, you're an adult." Nightmare glanced over said man with his single eye, not looking the least impressed, his arms crossed around his chest as if to defend himself from the wave of cringe he was the victim of. "Don't you think you're a bit too old for this?"

The bratty princess, as everyone liked to call Killer, gasped. "Too old for this?" He repeated, offended. "You're too old to be living!" He huffed, still holding the fake wand in his hand. "You clearly don't understand the Halloween vibe enough for a guy named Nightmare!"

"He's still our boss you know." Dust suddenly appeared from around the corner, wearing a strange dark robe that possessed a pointed hoodie that was of course worn over his face. The number of times he would come out of his room without a hood or something to cover his face could really be counted with one hand. "You still have to show him some respect."

"I don't see why I should!" He replied, turning his gaze away from Nightmare. "He's not showing any respect for Halloween!"

"We know that it's a hobby of yours to dress up, Kills." Horror also appeared not long after, wearing a bloody apron and holding his axe with one hand. Honestly speaking, it was hard to tell whether he was wearing a costume or his usual outfit. "But Halloween is just something to have fun with, there's no need to argue."

"I'm going to ignore the fact all of you have decided to follow Killer in his deranged hobby--"

"SO, DRESSING UP IS DERANGED BUT KILLING PEOPLE ISN'T??" Killer angrily interrupted, earning an annoyed glare from the guardian of negativity.

"--And ask what are you even supposed to be? I get that Killer is supposed to be a sort of wizard--"

"I'M NOT A WIZARD. I'M A SEXY WITCH, GET IT RIGHT!" As if to put emphasis on his point, he tipped the comically wide hat on his head, showing off the bat trinket attached to the base. He also twirled on his heels to let the thin layer of constellations flow with his movement, the dress underneath it swaying with the stars. 

"But what are you two?" Nightmare finished his sentence, having long mastered the art of tuning out Killer's rambles. Sometimes, he kind of wished he were back to quietly obeying orders and behaving like a puppet rather than an individual.

"I'm an evil mage, I think." Dust shrugged, lifting his robe, and stuffing his hands in the pocket of his shorts. From what Nightmare could see, he was still wearing his usual attire beneath the clock. 

"You think?" Nightmare raised an eyebrow.

"Yeah, Kills kind of... threw that costume at me and begged me to wear it and be his 'hot and mysterious side kick,' whatever that means." He replied with a flat tone.

"I see..." The mental image of Killer latched onto Dust's leg as he wailed for him to try the costume while he is trying to kick him off wormed its way in Nightmare's brain. He decided to keep that thought to himself to laugh at later. "What about you Horror?"

"I'm a..." He furrowed his eyebrows or at least that is what Nightmare assumed he did, it was sometimes hard to tell with his head wrapped in so many layers of bandage. "Butcher."

"Was that the end of your sentence?" Horror nodded.

"Wow, you guys sure look so excited for Halloween." Killer placed his fists on his hips, eyeing them with disappointment from the side. "At least try to look the part, will ya?"

"It's not our fault if we have better things to do than celebrate Halloween." Dust replied cynically, most probably rolling his eyes behind the hood.

"Better things to do? Like what? Killing people?" Killer sneered, vaguely looking mad. "Whatever! Where's Oreo by the way?" he asked, looking around in search of the monochrome emo.

No sign of him was found.

"I sent him to the Star Sanses base to gather them here." Nightmare explained, getting his attention back.

"Oh, was he dressed up too?" He had such hopeful eyes, well, as hopeful as his lack of irises could muster, that even Nightmare felt kind of bad for answering him negatively. 

Fortunately, it seemed like one of his other boys got him covered in that aspect.

"Cross is way too uptight to do that sort of thing, you know it as much as we all do." Dust spoke, making Killer sighed. "Though, I'm sure that he likes Halloween anyway considering how much he likes chocolate."

"A liking that I would never understand." Nightmare added, grimacing. Sweets have always been the bane of his existence and it was not about to change any time soon.

"You just have no taste!" Killer shouted back, somehow looking even more annoyed than he did a few minutes ago. "Chocolate is the best thing that mankind has ever created!"

Nightmare was about to respond when something in the air suddenly sizzled, the space being ripped opened by a glitchy rift that led to a completely blank and white space, the whiteness only disturbed by thin blue threads that covered the... ceiling? Like a spiderweb.

Soon enough, a dark-haired man popped from the other side of the portal, walking out of it with his usual outfit, the only thing amiss being a new kitsune mask on the side of his head. 

"I don't know what started this talk about chocolate," He began, dusting his clothes. "But I've got to agree with the twink there, chocolate is the best thing mortals have ever come up with."

"I know that I should be mad you called me a twink." Killer remarked, tone blank. "But I'm just so happy to have another chocolate lover in the house, it's been so long." He brought out a tissue unexpectedly, feigning wiping his tears. He did not dare act on it though, he would not want to smear the tar all over his cheeks.

Horror looked confused. "But Cross left a few minutes ago..."

"You wouldn't get it Horror, as sweet as you are." Killer smirked. "Get it? Because chocolate is sweet?" Horror and Dust both snickered at the joke while the two balance keepers gave him a deadpanned expression.

"...Anyway," Nightmare turned back to Error; his single turquoise pupil fixated on Error's mask. "Of all people, I did not think of you as the type to partake in such childish activities."

Error rolled his eyes as he arranged a swing for himself thanks to his strings. "Times change, and it is quite amusing to see those abominations enjoying such simple activities. You are not implying that you have never been curious about the anticipation, are you?"

Nightmare crossed his arms, digging his hands in his sides. "You should know that I have little interest in what mortals draw positivity from." As they spoke, Nightmare could feel the stares of his subordinates moving back and forth between them.

Just as he thought it could not get worse, Dust spoke, shattering that false impression of safety.

"Gay." Error and Nightmare turned to him, glaring and blushing. 

He raised his hands in the air. "What? I'm right!"

"I am with Dust on that one." Horror said, earning an eyeroll from the lord of negativity. 

"Of course, you are, you would even tell Ink he's got a good memory as long as you get to cuddle with Dust in the end." It was this pair's time to have their cheeks dusting pink.

Error recovered from his previous stunned state and nodded. "I don't know if whatever's going on between you is supposed to be a secret but if it is the case, then you are absolutely terrible at hiding it."

His words made both turn away, Dust pulling his hood down in front of his eyes and Horror scratching his neck nervously.

"Wow, I feel so left out." Killer pouted. "I miss my--"

Then, the doorbell rang. Nightmare's head lifted. "Ah, they must have arrived."

He went to open the door and sure enough, Cross's composed expression came into view. "Hello sir." He greeted him formally, slightly bowing down. "I have escorted the guests as you've instructed."

"Why are we here again?" Nightmare vaguely heard Ink ask, Blue sighing as his brother Dream proceeded to repeat the agreement for perhaps the thousandth time ever since they left their base.

"I can see that, thank you." Cross nodded and walked past him inside the mansion, immediately being tackled in a hug by a feral witch whose first instinct was to pepper his face in kisses. 

He shook his head from this horrible vision and turned back to the Star Sanses. Their leader, Dream, smiled at him half-happily and half-shyly. That expression was odd on his face, but he could not really blame him for it either, their truce did come unexpectedly.

"Greetings brother." Instead of a verbal response, Nightmare waved awkwardly. It must have been a wrong decision since almost immediately, Dream's hand quietly snaked toward the end of his ponytail as he started to play with the strands. He had come to learn that he did that when he felt particularly uneasy.

He took a deep breath. "Hi Dream." 

He smiled softly, Blue stepping closer to intertwine their hands. He gave his a squeeze as Dream spoke up again. "Can we come in?" 

"Of course, don't forget to take off your shoes." The trio nodded, Ink playing with his scarf trying to search for why Dream and Nightmare were not fighting now before they all came in.

He was about to close the door when he realized that an aura could still be sensed nearby. He moved his single eye toward the source and his eye narrowed. "And what are you doing here?" He questioned, his tentacles swaying behind him in wait.

Close to there, Color scratched his neck nervously, his ridiculous devil costume doing little to make him laugh. He still remembered that time he shot him with his ridiculously big and weird weapon.

He was not going to let that pass so easily.

Even if he had to admit that he deserved that at the time.

"I'm sorry sir." Cross spoke up next to him, maintaining eye contact with his superior. "I heard that Killer was quite fond of him and since we met him on the road, I took the liberty to bring him too." He bowed down apologetically. "My most sincere apologies, I should have asked for confirmation before doing so."

Nightmare shook his head. "Stand up." He obeyed immediately. "It's no issue but do notify me next time you want to invite another person." Cross nodded in confirmation, trying hard to ignore the lipstick all over his face.

The author of said marks appeared next to them, about to ask what the two of them were talking about and that is when he noticed Color standing not too far from the entrance.

He froze as their eyes met.

They stared at each other in silence for a few more seconds before Killer zoomed past the two before launching himself at Color, tackling him into a hug. The latter yelped as he found himself pinned to the ground.

"Uh..." He took his eyes off the piece of skin revealed by the window in his outfit near his soul. "Hi?"

Killer leaned down and crashed their lips together, much to Color's surprise again.

"Oh my..." Blue awkwardly let out at the sight, Dream chuckling next to him as Ink moved toward a painting hanging on the wall.

"And you're okay with that?" Dust questioned Cross; eyebrow raised.

The latter smiled. "If it makes him happy, I don't mind sharing."

He yelped as Horror playfully elbowed him. "You're hiding your game well, but I do hope everything goes alright for you three."

Cross chuckled.

Killer finally let Color breathe after a few seconds, sitting up on his waist as the latter sucked in some air.

"Today is the best Halloween I've ever celebrated!" He announced with a big grin, making most people.

Nightmare shook his head, a small smile stretching his lips.

He guessed allowing such an event sometimes is not the worst thing he could do.

Sneak peek

Nightmare breathed deeply through his nose, his head resting on his hand, his single eye blew wide.

This... this was seriously the worst.

How did he not realize how wrong his thoughts were? How... foreign they were to him? How did he not realize how out of character he was being? 

And most importantly, when, and how did he turn into such a monster?
