Summary:

Tommy meets demon slayer.

Tommy wanted to be safe, sure but going through a portal that lead to who knows where because Phill told him it was safe? Why not!

Notes:

It’s not finished!! I’ll try to update once a week but no promises. Some chapters may take a few more days than others as my schedule and my motivation can change quickly.

This chapter was written in a span of 6-8 hours. I had to keep taking breaks to let my cat out and back in. And I want to make sure each chapter has at least 2,000 to 3, 000 words more if I can help it.

I might rewrite chapters or add things to old chapters as I go. (The end interaction of this chapter has been changed! let me know if you liked the old interaction better.)

(please ignore any spelling mistakes as I am dyslexic but I’ll try my best to keep spelling mistakes or errors to a minimum! But if you cannot read it or don’t understand what the word is supposed to be, please let me know and I’ll fix it.)

Anyway I hope you enjoy!!

(See the end of the work for more notes.)

Chapter 1: Portals

Chapter Text

Tommy looked around the spruce forest, unsure where he was supposed to be going. He had gotten a message from Phil, telling him to start heading to –1629, -1982. (Tommy wasn’t sure to believe Phil but decided it was better than hiding from Dream in a hole).

As Tommy climbed over a particularly large fallen tree, he saw what Phil was talking about. A portal made from an unknown material, but glowed bright red. He started to slowly walk towards the Portal. Very confused on why Phil had told him to come here.

(“You must trust me on this. I don’t want him to hang on the server anymore. M’Lady has assured me, he’ll be safe” Phil told Techno in a desperate tone.

Techno just shook his head, looking at his friend with understanding. “Very well. If the Goddess says its safe, then I won’t stop him... or you.” Techno, uncrossed his hands, putting one on Phils shoulder.

Phil only shook his head, looking at Techno with a softened but serious face.)

As He approached the portal, Tommy felt a slight tug towards it. As if he was being pushed in. He took another step. Now that he was closer, he could see the detail in the marble that stood as the frame. The portal was what Phil told Tommy to look for, now that he had found it... he wasn’t sure what he was going to do. Phil has told him to enter the portal, but not much than that.

Damn it Phil. Why couldn’t you tell me in your stupid letter why I had to enter? Tommy thought, with a frown. Tommy turned to look at the portal and held his breath. He took a step into the red portal, which disappeared the second he entered, only leaving a few red particles and a patch of bare grass.

 

In Demon slayer Universe-

The night was beautiful, she had to admit. If it weren’t for the man-eating demons that prowled around, she might have enjoyed it more. Luckily tonight, she wasn’t on any mission. She was off to talk with the love hashira, Mitsuri.

As she walked through the gates of the Love estate, where Mitsuri was waiting by the door. “Shinobu! I hope it wasn’t such a hassle coming all the way here.” Mitsuri called out, waving her hands around. Shinobu gave a small laugh and a wave, as she continued up to the house.

“Not at all Mitsuri! What is it you wished to talk about?” Shinobu greeted the love hashira with a small hug. Mitsuri’s smile as she turned to lead Shinobu into her house. Without a warning, a scream sounded from behind them. Mitsuri yelped at the noise, before the two hashira turned and drew their nichirin swords.

“Fucking shit! You fucking twat!” a small figure yelled, out as it stumbled around. Shinobu looked at Mitsuri who looked just as confused as she was. Looking back at the creature, it did not see human but didn’t seem like a demon.

“Oh My! Such language.” Mitsuri gasped, covering her mouth. Shinobu wasn’t sure about what she was supposed to do. She knew she had to behead it, if it were a demon. The creature looked over at them, under the moonlight its bright blue eyes seemed almost scared, before the creature turned and fled the estate.

Shinobu looked over at mitsuri, before following the creature. “It must be a demon, right? But why didn’t it attack us?” Mitsuri asked as they followed the creature.

Shinobu just shook her head. They spotted the creature further ahead, crouched behind a tree, as if it were trying to hide. They slowed down a bit to catch it by surprise, so it didn’t run again. As they got closer, they heard the creature whisper-yelling about someone named ‘Phil’.

“Why did I trust him? I should have just stayed in that bloody hole! Fucking bird man tricked me!” As the two hashira were a few steps away, they realised the ‘creature’ was just a boy, who seemed to be 16 or 17 years old and seemed to be on the verge of crying.

“Are you ok, boy?” Mitsuri asked, crouching down next to him. A short scream came from the boy's mouth, before he went to get up and run again. Only to realize Shinobu was standing next to him, still holding her nichirin sword. “Go away!”

The boy tried to make himself smaller, looking wildly up at the two hashira. Shinobu was a bit worried about the boy's health, he seemed dehydrated, malnourished and scared. Extremely scared. And Shinobu might know why. “Are you a demon?” She wondered out loud.

Mitsuri gave Shinobu a weird look before standing back up with a sad smile. Not every person is a demon, but it was better to be safe than sorry. Afterall a boy out in the middle of the night, for seemingly no reason. Mitsuri had wanted to make sure the boy was alright but if Shinobu thought the boy was a demon, she couldn’t say otherwise. “W-what?” the boy stuttered, staring at Shinobu.

“You heard me Boy. Are you a demon?” she asked again, lifting an eyebrow. Mitsuri had put her sword back but slowly went to get it again. She knew Shinobu wouldn’t be able to behead the demon, only give it a lethal amount of wisteria poison. The boy didn’t answer Shinobu, but tears started forming in his eyes.

When the boy finally answered, Mitsuri was instantly saddened. She had hoped Shinobu was wrong in her assumption. She hoped the boy was human and just lost. “what's it to you?” He mumbled, wiping away a small tear that escaped his eye. Mitsuri then saw why Shinobu assumed the boy was a demon, when his tail flickered carelessly beside him.

Shinobu shook her head again, looking down at the demon. “Because we are Demon slayers, Hashira to be exact. So, if you are a demon, we’ll have to kill you.” she answered, nonchalantly. The boy’s eyes widened again. As he started to mumble things like;

“Phil said this place was safe.” and “Kill? Maybe they are wrong?”

“I can assure you boy, I am not wrong.” Shinobu retorted, looking at mitsuri. Who seemed to be off in her own world. She returned her attention to the demon and noticed he was looking behind them now. When she looked at herself, she saw the sun rising. “Ahh, well we’ll just wait here then.”

Mitsuri seemed to snap out of her imagination and looked at the sun rising. She gave a sad smile to the demon boy. Shinobu seemed to watch the demon as the sun settled, making the demon boy glow a bit. What came as a huge shock to the two hashira was the demon was still sitting there with a confused look. “How?” Mitsuri looked at Shinobu, thinking she had the answer.

Shinobu looked back at Mitsuri with an equally confused look. Shinobu glanced down at the boy, and with such quick movement, hit the side of the boy's neck. Which instantly made him go limp. Mitsuri picked the boy up without a word and the two started to head towards the Butterfly estate.

Tommy woke up on a white bed, very confused about what happened the night before. He couldn’t remember very well. Ranboo's the one who's supposed to be bad at remembering. he thought sourly. He decided instead of being mad at ranboo, he might look around. As he tried to sit up, his head started to hurt badly.

He groaned but stayed sitting up. As he sat there, the door opened, and a girl walked in, almost dropping what she was holding. “Lay back down! Do you hear me? Lay back down!” the girl yelled at Tommy, trying to push him to lay back down.

Tommy listened and laid down; his head didn’t hurt as much once he did. He looked around the room as the girl went back out again, saying something back ‘when will they learn.’

Rolling over to lay on his stomach, Tommy flicks his tail around trying to remember what had happened the night before. He remembers Phil’s letter, and the portal but not much after that. He looked up at the door again, realizing he hadn’t heard it be locked. He slipped out of the bed; his head didn’t hurt as much as it did before as he opened the door.

He wondered what he’d do, once he found a way out of this place. He wants to try and find that portal and go home. Tommy walked around the hallways for a bit, before he almost ran into a smaller girl. Who promptly squeaked at Tommy’s tail and ran. With a huff, Tommy continued to look around.

“And where are you off to, young man?” a voice tommy recognized sounded from behind him. Tommy froze, a shiver going down his spine. Which made his tail curl around his leg. He lowered his head as he would when speaking to dream and turned to look at the lady from the night before.

“No where ma’am” Tommy answered, his voice shaky. He didn’t want to show these people weakness but for some reason this lady made Tommy want to go back into a hole. Tommy’s body started to tremble as the lady stared at him.

The lady slowly shook her head, her small smile dipped smaller. Not knowing what to do, Tommy guessed it would be easier to slowly walk away. “Where do you think you are off too now? Please, let's sit.”

Tommy turned back to look at the lady, his body still trembling, and gave her a weak nod. The two found a spot to sit outside. Tommy chose to sit in a shaded spot, hanging his legs off the edge of the veranda. The lady stood in front of him, her small smile had returned as she watched Tommy fiddle with the hem of his sleeves.

“what's your name?” the lady questioned, keeping an eye on Tommys body language. Tommy just looked confused for a second before giving a short hum. “My name? It’s Tommy. Big Man tommy” He whispered that last part with a sneer.

Shinobu nodded along, as she chose to ignore that last part. “I am Shinobu Kocho. My master has requested, I am to bring you to meet him and the other Hashira. We'll be leaving soon.” Shinobu dipped her head, telling Tommy about the others who work at the butterfly mansion and How things worked. What she forgot to tell tommy or even mention was the other hashira or why he was here.

When they were ready to leave, Shinobu made a small deal of telling tommy to behave for the Kakushi, who would be carrying him. Just before tommy could understand what she had meant, she had hit his neck again. Just as he realized what she had done, all she could think of was how aggressive Shinobu was.

--

“He doesn’t burn in the sun. Even you can see that, Sanemi.” Shinobu challenged, pointing at Tommy who was clearly in the sun, though asleep. While Shinobu hated she was protecting a demon, it was clear he was special and maybe in a way that would help the corps. “I do not care, he’s probably eaten hundreds of people” a rough voice stated, quite harshly.

“Not--me. Quack man do though.” Tommy managed to grumble; he could tell someone had tied him up, but the sun was so bright he kept his eyes closed. He felt like laughing, he knew if he tried, he’d be out of these ropes in no time. He decided against it, in case they try to kill him like Shinobu said.

“What did you say, Demon?” the rough voice barked. Steps sounded like they were coming closer to Tommy, but he didn’t care at this point. A foot found its place on Tommy’s side, holding him there. Opening his eyes, Tommy's eyes were met with a tannish man with white hair and lots of scars.

“Quack man eats people, but I personally find it disgusting and have never done it myself.” Tommy Grunted. “Now please get your foot off me.” and to his surprise, the scar faced man did. And to add to the confusion, the man walked over towards the people who were watching.

After a few seconds, Tommy decided he wasn’t going to be scared anymore. These people didn’t seem to be like Dream. Even Shinobu who was scary wasn’t compared to him. So, his confidence went up in seconds. Tommy knew not to underestimate his opponents, so he didn’t start to question if these people were stronger than him.

He ignored the people Shinobu was talking to and their conversation. as he started to slip out of the rope he was tied in. It was starting to get uncomfortable. Once he was out of the ropes, he just stood up and stayed there. He knew running wasn’t an option from what Shinobu said.

“Why did you get out of the ropes?” a quiet voice asked from next to him. When Tommy looked, a taller man was there. Shinobu said the ‘jacket things’ that people wore were called kimono, this man had a multi-colored one. Tommy nodded at the man's question before shrugging. “Bored”

The man seemed to take that as an answer and looked back at the others. Who seemed to now be arguing about a person named Kamado. Tommy flicked his tail around, annoyed. He wasn’t sure what he was supposed to be doing but it was boring. “I’m Tommy by the way”

“Giyuu” The multi-colored kimono guy answered with his own name, before the silence took over again.

--

Tommy doesn’t know how it happened but now he’s on an undercover stage like thing with the scar faced man from before. Whose arm is bleeding now, Tommy scrunched his nose at in and took a few steps back. He wasn’t happy that these people thought He was eating people. “Ew, that's disgusting.”

That one sentence seemed to confuse the people who were standing around. “don’t you find it delicious?” the scar face man, seemed to take a long pause unsure of what he was going to do next. At the question, Tommy made a hiss noise in revulsion.

“So, he’s like that Kamado girl?” some dude with a snake and pretty eyes said, sarcastically. “He doesn’t seem very flashy!” Tommy liked the accessories that dude was wearing. “Just behead him” the scar face dude scowled.

“I would prefer to not be beheaded?” Tommy tried to reason. “Also, I have no clue where I am.”

A very tall, blind man named Gyomei, Told Tommy he was in Japan in the era that was called the taisho period. Which tommy was still confused by both and asked him to explain who everyone was. Apparently, these guys were hashira and They were to kill man-eating beasts called demons. Which explains why Sanemi (Scar face man) wanted to know how many humans Tommy ate.

Then it was Tommy’s turn to explain to the Hashira who he was, it was clear to some of the Hashira that Tommy was from somewhere different. Before Tommy started to explain, a crow came and sat on his shoulder, which wasn’t odd to the hashira as their own crows will hang around or on them.

The odd thing was when the bird chirped, and Tommy answered it in another chirp. “So, apparently, I am in another universe and this place is Called Demon slayer or Kimetsu no yaiba. And I am from the Dream SMP” Tommy explained, shifting from foot to foot.

Tommy paused again, not knowing how to explain his world. “We have hybrids, humans and Godlike creatures? I suppose. I don't know how to explain my world?” Tommy tried, fiddling with his hands.

“What about those Godlike creatures? They sound Flashy!” Tengen exclaimed, his arms still crossed and a mostly blank face. Tommy nodded, he could explain them, right? He would at least try. “Could you explain Hybrids?” Shinobu asked, with a short nod.

“Well Hybrids are part human and part animal or mob. Like.... Fundy!” Tommy recalled how Fundy was Part Fox, and how he had a snout, foxlike ears and tail and even paws. He even spoke about some other hybrids like captain Puffy who was a sheep hybrid but only had horns, ears and a tail like, Tubbo who was a Ram hybrid.

Tommy told the hashira all about hybrids and that most hybrids eat what their animal counterpart ate but could eat human foods if they desired to. He told the hashira that Godlike creatures, were people who couldn’t die (by swords or the sun) or people possessed or blessed by certain gods, like Phil and Eret.

Unlike Eret, Phil could die but only by being wounded. Were as Eret would live forever. Tommy explained the gods and goddesses of his world. Lady Death- who guided those to the afterlife. XD (or Prime)- who was the main god of their server and protected those who worshipped them. Drista (Choas divine)- who would torment mortals for the fun of it, although she was nice to tommy. And last but not least the Blood God- the most violent of them all, who roamed Tommy’s world in an immortal's body.

--

“that's it, I think?” Tommy had refused to answer any questions that related to Tommy’s family or how he got his scars but was open to other questions. Sanemi was the one to ask about Tommy’s Horns and tail.

To which Tommy had Told him that demons weren’t as common in his world but there were indeed demons. Tommy told him that in Tommy’s world he was classified as a demon, he didn’t eat humans or really any sort of meat that wasn’t fish.

And that in Tommy’s world there were two demons named Bad Boy halo and Sapnap. And Tommy ‘never’ told the hashira this but Sapnap’s name is actually Pandas.
