Chapter Text
“Where.. Where am I?” Izuku Midoriya looked around. He was in some forest, snow under his feet. It was a beautiful sight, but a confusing one. How am I here? I’m pretty sure this isn’t Musutafu.. The boy shuffled up onto his feet and he shivered. It was pretty cold and he wasn’t necessarily wearing snow appropriate attire.
Before this all happened, Midoriya had gone to a store to pick up the snacks for his class movie night. He didn’t remember how a young boy had seen him drop some money, picked it up and handed it to him, touching Midoriya's hand. It was the outcome of a quirk, to which the boy accidentally activated. On the way back to the dorms, Midoriya was thinking about how excited everyone was to watch the show called Demon Slayer. He never watched it before, but according to the majority of his classmates, it was an exciting series. Suddenly he grew dizzy, and a few moments later he passed out, and awoke to this unfamiliar setting.

“Hey guys? Have any of you seen Midoriya? He still hasn’t come back with our snacks!” Kaminari whined dramatically.
“Oh hush up Kaminari, I’m sure he’ll be back soon” Jirou rolled her eyes setting up the blankets. The entirety of Class 1-A was in the living room.
“His ass better hurry the fuck up or I’m starting without him. I don’t give a damn if he hasn’t watched this!” Bakugo sat down on the couch angrily. Uraraka made herself comfortable on the floor with pillows and blankets surrounding her. She looked out the windows of the UA dorms.
I hope he’s okay. She thought growing worried.
…
30 minutes had passed. And no sign of the green haired teen. Some people were starting to get concerned, but most were annoyed.
“Guess we’ll just have to explain the beginning when he comes back” Mina shrugged and exhaled disappointedly. Murmurs of agreement rang around the room.
____________
Izuku walked and walked, shivering from the cold. He almost collapsed when suddenly yelling caught his attention. His eyes and ears perked up. He started running towards the noise. He hid behind a tree and his eyes widened. A boy? And a girl..
“Nezuko! Hang on Nezuko! Don’t give in!” The boy yelled, he was yelling multiple phrases about her not giving up on something. Izuku noticed how he was holding a stick against her mouth. Is she trying to attack him? Should I intervene?.. Suddenly he heard running from another direction. He tried hiding himself even more against the tree. A man with a sword ran to the two on the ground and he was.. Gonna strike them with it! Izuku moved out of the tree’s way but then he suddenly flew back. An enormous gust of wind had hit him and he stumbled back.
Oh no, are they okay!? Midoriya ran and leaned against the tree, immediately looking for the boy and girl. He exhaled when he realized they were okay but the girl was struggling against the boy holding her back. The man with the sword suddenly spoke.
“You call that thing your sister?” He said. Midoriya’s blood immediately boiled in anger, who does he think he is insulting someone's family member like that! He blinked and the girl was no longer with her brother, but in the hands of the man. A large gust of wind suddenly surrounded them and Midoriya flinched. He couldn’t see anything but he could still hear.
“My job is to slay every demon I find.. Which means I have to decapitate you sister here.”
Izuku pressed his hands against his mouth to stifle a gasp. Demon? Decapitate? Seriously!? He heard the boy argue back, defending his sister. Midoriya listened closely to an explanation of how demons form.
Suddenly the man raised his sword and the boy screamed begging him to not kill his sister. Izuku couldn’t wait any longer! He came out from hiding and using Blackwhip, he restrained the man from being able to move his arm. The man's face didn’t change from the emotionless expression it had on. The boy's eyes widened at the green haired boy who was glaring at the one who attempted to decapitate his sister.
“Please. Don’t kill his sister! Do you have any idea of how traumatizing it is to see a family member's head get cut off in front of you!?” Midoriya yelled. The man glared back.
“You’re not very good at hiding” He said bluntly, “Who even are you, why are you dressed in clothes that are the complete opposite of what you are supposed to be wearing during the winter. This is none of your business get away from here!,” He then turned angrily to the boy who was begging on the floor, “And you! Don’t grovel like that and give your enemies the chance to kill you!”
Both boys' eyes widened as the man lectured them. The burgundy haired boy’s eyes started to tear up as the man yelled at him. The man suddenly kicked snow at Midoriya’s face. He stumbled back falling and he gasped in surprise, his hands instinctively going up to his face and letting Blackwhip go in the process. He stabbed the girl in the chest and her brother screamed, “don’t you touch her!” the boy threw a rock to which the man dodged. Another gust of wind surrounding everything. Making it difficult to see.
By the time Midoriya was able to see clearly, he saw the boy on the ground knocked unconscious and an axe, barely missing the man's head, his eyes widened. Suddenly the boy’s sister kicked the man and started running towards her brother. But Izuku saw no intention of friendliness in her, he was about to use blackwhip to restrain her when suddenly she stood protectively in front of her brother. A few moments later she tried attacking the man, to which he knocked her out seconds later.
Midoriya realized both the boy and the girl were knocked out, giving the swordsman a chance to kill the girl he’d been wanting to decapitate, “Wait!-”
“Don’t worry, I won’t kill her.” The swordsman seemingly read his mind, “Now, are you gonna tell who exactly you are? And what exactly were those black tendrils that shot out of your hand.” Midoriya shrank back a little at his gaze.
“I’m.. Izuku Midoriya, and that was part of my quirk..? I don’t exactly know where I am. I was trying to get back to my class when suddenly I passed out and woke up here in this forest.” The boy looked down with his brows furrowed, “The things you were talking about.. Demons? They exist here?” He looked up at the man whose face reminded him so much of the scar faced boy back in UA.
The swordsman tilted his head, “Quirk?” The green haired teen nodded.
“I’m definitely not where I’m supposed to be if you don’t know what a quirk is. It’s like a superpower. I have a strength enhancer, and those tendrils are called Blackwhip” He explained. The man simply stared, and then sighed, “Okay then. Let me tell you the story of demons, and how our job as Demon Slayers is important”
Then suddenly it clicked. Midoriya's eyes widened. D-Demon Slayer? Am I.. am I in the show my friends wanted to watch? But how!? He shook his head. I’ve never seen it before. It’s definitely important for me to listen to this guy.
____________
Class 1-A were in their respectful spots in the living room. Watching the T.V.
“I love Nezuko, she’s so cute!” Tsuyu exclaimed, cupping her face. Some people were heard agreeing with her.
“You say that, as she’s trying to attack her brother?” Iida shook his head with a faint smile. The scene changed to Tomioka running towards the siblings.
“You guys cannot convince me that he does not remind you of Todoroki” Sero crossed his arms waiting for someone to think they could “unconvince” him. Todoroki had a small smile.
“Nah I’m with you on that one” Kaminari started laughing.
The Tanjiro on screen screamed at the Hashira, begging him not to kill his sister. Although mostly everyone already watched this scene, some were practically shaking in their seats of the intense scene. They all watched Tomioka raise his sword slightly when suddenly a black tendril was seen wrapping around the Hashira's wrist.
“Wait. What. I don’t remember this happening?” Kirishima tilted his head in confusion.
“Me neither! What??” Hagakure exclaimed.
Suddenly the scene changed, the camera was behind Tomiokas head, slowly going to side to reveal a familiar green haired boy, who was wearing the dumbest clothes you can during winter, the giveaway of their classmate being the white t-shirt saying Shirt , he was glaring at Tomioka with a black, outlined in a light teal color tendril, shooting out of his hand.
Bakugo suddenly grabbed the remote and paused it right where you can see the entirety of Midoriya's face and upper body. Everyone froze, not making a sound, then Bakugo spoke, “For the Love of All Might, please, tell me that is not the damn nerd”
“Uhm.. how the actual, HELL?” Kaminari screamed.
“Midoriya!?” Todoroki’s eyes widened.
“Is he stuck in the T.V!?” Ojiro suddenly stood up, seriously concerned for his classmate.
“We should notify the teachers!” Mina yelled, throwing off the blanket over her and starting to get up.
The class scrambled in a panic. A few took out their phone to take a picture, others tried contacting the teachers, others were still frozen in place staring at the screen.
……
“Hm.” The principal clasped his paws together looking at the green haired boy on screen, “This is.. Quite the predicament”
Midnight placed her hands on her hips, “This is most likely the outcome of a quirk. But like.. How?.. What kind of quirk would get him stuck in a show, on T.V?”
“Why is it always Midoriya?” Aizawa sighed, placing a hand on his forehead.
“You said this was a show right? Maybe in order for him to get out we have to watch it all in order.” Present Mic suggested. Some students looked at each other in worry.
“Of all the shows.. He just had to get stuck in this one” Shoji looked down, his face an expression of pure fear.
“Why what's wrong with this show?” All Might grew worried for his successor, he’d hoped perhaps this was an ordinary show that he’d be able to get out of in no time.
The 1-A students look at each other in worry once again.
Kaminari spoke, his face pale, “This show is very gruesome. Midoriya.. Has to worry about not getting mercilessly devoured by demons.” All the teacher’s eyes widened in horror.
“And with him being there. He’s completely changing the timeline. We have absolutely no idea what is going to happen. Only the major demons he might encounter” Uraraka shakily placed her hands on her face, white as a ghost, worried for her friend.
“He doesn’t even know what he's about to go through!” Yaoyorozu exclaimed, her fists balled up, “He’s never watched it before.” The teachers sighed.
“How many hours do you estimate we’ll have to watch before it ends?” Vlad King asked.
“Not hours. Days. Guys I know we are all going to be shaking in suspense watching him, but we have to remember to take breaks, eat, drink, and sleep.” Sato said. Some hesitantly nodded.
“Should we transfer this to a larger T.V?” Cementos asked. Everyone agreed.
The 1-A students began making the space larger since the teachers would now be joining them. Present Mic went to join Cementos to get a larger T.V. About 30 minutes later everything was now set up. All the students were situated in their spots, not very spread out, as they knew extremely intense scenes would show, and they'd rather be next to someone when those scenes came. The teachers were also seated.
“Alright everyone, I want you all to take a deep breath in and out. We know this is going to be.. Really. Really. Intense, I’ve watched this show just a little but we have to try our best to not panic. Alright?” Aizawa told the entire class. Everyone had followed what he said about breathing.
“Okay, get ready I’m unpausing.” Bakugo said, lifting the remote. Click.
The scene unpaused from where Midoriya was glaring at Tomioka.
“Please. Don’t kill his sister! Do you have any idea of how traumatizing it is to see a family member's head get cut off in front of you!?” Midoriya yelled. Tomioka stood there emotionless until he glared back.
Some of the class giggled, saying how thoughtful Midoriya was.
“You’re not very good at hiding” Tomioka said to Midoriya bluntly.
The class pondered for a moment. Hiding?
“Who even are you, why are you dressed in clothes that are the complete opposite of what you are supposed to be wearing during the winter. This is none of your business get away from here!,” He then turned angrily to Tanjiro, “And you! Don’t grovel like that and give your enemies the chance to kill you!”
Aizawa shook his head, “He’s kind of right”
The T.V showed how both of the boy’s eyes widened as Tomioka lectured them both.
“Jeez Tomioka can be so harsh sometimes..” Mineta shrank a little at how the Hashira was yelling at Tanjiro and his classmate.
The class gasped when Tomioka suddenly kicked snow at Midoriya’s face. The green haired boy stumbled back falling and gasping in surprise, his hands instinctively going up to his face and letting Blackwhip go in the process. Tomioka stabbed Nezuko in the chest and Tanjiro screamed, “don’t you touch her!” He threw a rock at Tomioka to which he dodged with ease. A gust of wind surrounded everything. Making it difficult to see.
All Might sweatdropped at how Midoriya let go of Blackwhip because of that swordsman's kick of snow. If he used Blackwhip to restrain a villain and the villain made a similar move like that, it would be horribly dangerous.
The scene showed Tanjiro how Tanjiro and Nezuko were now knocked out on the floor by Tomioka. Midoriya quickly whipped his head towards Tomioka, “Wait-!” he yelled but Tomioka assured the boy he would no longer hurt the girl. Instead he asked about who Midoriya was and what his tendrils were all about. To which Midoriya explained to him about quirks. The class sweatdropped when Midoriya started explaining how he was pretty sure he was no longer in his world. Midoriya asked about demons, Tomioka said he’d explain it all to him. The scene showed Midoriya's thoughts to the entire class. Am I… Am I in the show my friends wanted to watch? But how!? Midoriya shook his head. I’ve never seen it before. It’s definitely important for me to listen to this guy.
“Yes Midoriya you are in there!” Mina yelled at the screen.
“Yes, please Listen to him or you’re gonna have no clue what you’re about to face!” Iida said.
Tokoyami shuddered, “Don’t you guys feel like it’s a violation of privacy that the T.V is saying his thoughts?” some shrugged.
The screen suddenly turned black and Tanjiro was shown starting to wake up. Tomioka asked if Tanjiro was awake and he immediately shielded his sister, he look to the side and the saw Midoriya next to him looking calmly at Tomioka
“What! We didn’t even get to see the interaction between Midoriya and Tomioka!?” Kaminari exhaled.
“We were robbed!” Hagakure fell over dramatically.
Tomioka said for Both Tanjiro and Midoriya to head to Mount Sagiri as soon as possible, to find a man named Sakonji Urokodaki. He told Tanjiro explicitly to not let Nezuko be exposed to sunlight, and then he seemingly disappeared.
Sero gasped, “Are we gonna see a montage of Tanjiro and Midoriya training together?!”
Tanjiro sat frozen staring at the spot where Tomioka once was, a hand was shown reaching towards Tanjiro, the burgundy haired boy looked at the hand and then up, the green haired teen had a very faint smile. Midoriya introduced himself and Tanjiro grabbed his hand, pulling himself up, nodding in thanks. Tanjiro also introduces himself and for Nezuko as well.
“I don’t know if I should envy Midoriya for being able to meet Tanjiro and Nezuko,” Aoyama said.
Mina elbowed him lighty, “Uhm hello! Do you want to encounter man-eating demons!?” Aoyama quickly shook his head.
The T.V showed 5 graves, Tanjiro was on his knees praying with his eyes closed, Midoriya stood next to Nezuko in sadness. Tanjiro stood back up after a few seconds. “Lets go” Tanjiro said to Midoriya and Nezuko. The siblings holding hands, Midoriya walking alongside them with a pained expression. Tanjiro looked back towards the graves, Midoriya gently laid a palm on Tanjiro’s shoulder trying to give him any comfort. Tanjiro grunted and closed eyes, looking forward. Midoriya saw determination in his eyes once Tanjiro opened them. He looked at Midoriya and nodded, reassuring he was okay. Midoriya nodded back and gave him a small smile. Then the 3 of them ran off deeper into the forest. The Episode Ended.
In the class there were very few people crying a little at the deaths of Tanjiro’s family.
“So much was said between Midoriya and Tanjiro, and they didn’t speak, the only words said were from Tanjiro, and he was talking to his sis and Midoriya” Jirou said.
“Ughhh why do I get so emotional whenever I see those graves!” Mina wailed dramatically.
“C’mon next episode Bakugo! I need to see them training” Kirishima said excitedly.
Bakugo looked at his Homeroom teacher for confirmation if it was okay to play another episode, the teacher nodded. “Alright alright next episode.” Bakugo raised the remote, click! Next Episode
