Welcome to this long mess! Enjoy!

~*~

Nezuko slowly crawled out in her small child-like form. Her pink eyes scanned the room before she stood and grew to full size. "Why... Was there a child on your back, let alone in a box?"

Hawks closed his wings around himself, completely confused. While Tanjirou and you just gave him questioning looks. He sat up, the wings extending slightly. "She'll die if she's in the sunlight, like all demons," Tanjirou explained. Keigo cocked his head in thought... 'Demon?'

Tanjirou gave his sister a head pat making her hum contently. "It's one of demon's weakness." You took a seat at the end of the bed watching Tanjirou as he checked his sister for any wounds. "Sunlight... Wait, she's a demon like you've been speaking of?"

You shot the blonde a glare. "Nezuko is nothing like those human-eating demons." Crossing your arms over your chest. You were suddenly tackled by the demon in question. Her arms wrapped around you while she hummed. "I missed you too, Nezuko."

Keigo's eyes widened when you mentioned 'Human eating' It was similar to the villain Moonfish. "These... Demons eat humans?" He asked, looking to Tanjirou for an answer. After taking a seat next to you, he answered his question.

"Unfortunately yes. It's how they gain power... The more they consume, the more power they gain." A sad look traced in Tanjirou's eyes. You sat up, eyes lowering to the floor.

"That's why the Demon Slayer Corporation exists, we're here to stop them from killing." You said, a heavy tone to your voice. Keigo took in the difference to you and Tanjirou's shift in mood. Knowing how it feels to be sad, he decided to change the subject.

"Well, As a Pro-hero, I'll help you to-er-three, get home." Standing, he shook his wings of the stiffness that laced throughout them. "I'll also close the blinds to the place so she can wonder."

You're head perked up, "blinds? as in curtains?" Standing, curiosity laced throughout you. A smile grew on Keigo's face. "Never seen automatic blinds before?" When the two slayers nodded, his smile grew. "Well, come on kids."

Taking off his jacket, he threw it on the couch in the living room. The three souls curiously followed. It was true that they hadn't seen much technology other in the few cities that existed back home. "Lower," He said. Something at the top of the windows slowly lowered, concealing the room in complete darkness. Then the light came back on. Amazement glittered in the teen's eyes.

"Have fun kids... I'm headed to bed," Keigo rubbed the back of his neck, vanishing behind a door. Sighing, he plopped down on the bed. Spreading his wings to full length, relaxing them. You watched his form vanish. Looking down at the floor, you began to worry. "What are we gonna do?" You muttered, pressing your arms into your body.

Your gaze flickered to Nezuko being her silly self, poking at an electric box of some sort. (Think you'll know it was microwave) The gash on your side ached, a dim reminder of what you had to get back too. A warm pair of arms wrapped around you, holding you close. A faint heartbeat echoed in your ear, calming your frantic nerves.

Your arms snaked around his waist, pulling him closer. Tanjirou's own heartbeat arose in his chest. Your warmth was so comforting to him. He placed a hand on your head, stroking the soft hair. His action made you shutter slightly. "You okay?" He asked, pulling back to look at you. "Yeah... It just cold in here for being the middle of summer." Tanjirou knew you were making something up since the cold never bothered you much.

A smirk grew on his lips. That look on his face made you emotionally melt in your spot. No way did he not know the effect he had on you. Tanjirou placed his hand on your chin, tipping it up to look at him. The way your eyes glittered in the artificial light made his chest tighten. He pulled away from you slightly, making your face start to heat. Even though, you promised yourself you wouldn't let it happen. "Okay..." He whispered.

Another soft laugh left his lips. However, he leaned close to your ear. "That's my (y/n)." You had completely forgotten about the situation you three were in. Nothing but the closeness of him to you filled your thoughts making your mind fuzzy. You felt a hand trail down your cheek, moving the hair from your face. The heat coming from his hand, sending sparks throughout your skin. "Promise we'll get back...?" You said weakly. Almost not able to talk at all. Be pulled away slightly, a smirk trailing on his lips. "... I promise."

Your gaze immediately went to his eyes. Stuck there in his gaze. Your breath catching in your throat. His hand rested just below your jaw. His fingertips entangling with your hair.

He had his gaze fixated on your lips. Now, selfish and illogical as it was, he wanted you to be his. His hands being the only ones to make you shutter. To make that crimson blush spread across your cheeks. To be illogical as to be the only one you ever looked at. He brought you closer, almost within the range of getting what he wanted. Your lower lip trembling with anticipation. Your eyes fluttered shut. Your heart was beating so fast and hard you were sure that Tanjirou could hear it.

A flow of electricity shot through your body. Migrating to every spot where his flushed skin touched yours. A smile unknowingly crept onto your lips, but your form couldn't move.

Even though his mind was fuzzy, the mere contact of his mouth on yours, sent chills and heat throughout him. Shakily, your hands raised upwards to grab a hold of his jacket, pulling him closer. Even though sloppy and slow, it was exhilarating to them.

Intoxicating enough to make his mind go completely blank except for the feeling of his skin on yours. In the end, Tanjirou was the one to pull away. This made you make a small sound of disappointment. The sound you made caused a smile to trace his lips.

"Like me that much? I'm flattered." He teased, earning a pout face from you. Completely flustered, you pushed him away. "I guess so..." You muttered, turning around. Tanjirou took the chance to wrap his arms around your lower waist, hugging you from behind.

A small chuckle escaped his throat and into your ear. "I like that about you...~" Another shudder shot throughout your body. "T-Tanjirou..." You chuckled, embarrassment seeping into your body. It caused a feeling to stir deep within your stomach, making you crave him more.

The way you said his name, it rolls off your tongue with such a voice made him weak in the knees. He leaned in closer to you, wanting you to repeat it. He could feel your breath hitch inside your chest.

Suddenly, you spotted a large ball near the couch in the center of the room. "Hold on... What is that?" You asked pointing to it. Tanjirou looked at it, "Taking a guess, some kind of chair." Your eyes began to sparkle. Ripping away from him, you walked over and plopped yourself in it.

It was surprisingly squishy and comfy. You looked to Tanjirou standing by your side. "It's comfy..." He cocked his head, now motioning for you to scoot over. He sat in it, falling against your body. "Whoa... it is..."

Shifting, you made it so you looked at him. Without another thought, you snuggled up. His semi incense smell lulling you off into a light slumber. A small smile pulled on his lips. Using his arm for a pillow, he took off his own Haori and threw it over the two. He didn't have the heart to make you move to the guest bedroom. So this odd chair would have to do for now.

"Hey... Tanji?" You said tiredly, now almost fully asleep. "Yeah?"

"You think... Zen and Inosuke are okay?" To be honest, Tanjirou didn't know the answer. He placed his head on your own. "I'm sure..." He had wondered if they had gotten transported to this world as well...

"DEAR GOD! WHAT'S HAPPENING!?" Zenitsu screeched, plummeting towards the ground. However, Inoskue was quiet. He held a screaming Zensitsu on his shoulder as they fell.

The thick black clouds made it hard for anyone to see past. Inosuke could clearly see past all the thick smog in the air enough to see where to land. Shifting his weight, he did a move to lessen the impact of the dark alleyway they came too. "Oh my god... We're ALLLIV-" Inosuke clapped a hand over the male's mouth. After a second, Zenitsu could hear the sounds of people fighting further down into the alleyway. "A fight?" Zenitsu questioned. "I-is there a demon here?"

Without warning, Inosuke grabbed Zenitsu by the collar and started to yank him towards the battle. The sounds of several people echoed out among the walls of the buildings.

A loud distributed screech echoed in the air. Zenitsu covered his ears, whimpering at the loudness of the sounds. A large creature stepped into view. It's blackened body, brain exposed through the skin with the bloodshot eyes popping through.

"Ew, ya ugly." Inosuke snapped. He let Zenitsu go in order to take out his swords. The large creature screeched, making Zenitsu back up. "You're time is over, Demon!"

The large 'demon' drew back a fist. Inosuke jumped up to dodge.

"Kid! Get away from that thing!!" Zenitsu looked to see a large guy coated in fire running towards them. Before he could reach the teens, the 'demon's' arm connected with the ground. A large crater formed underneath it from the pressure. "He's on fire!!" Zenitsu screeched. Inosuke ran up its arm. While jumping past it, the two blades cut through its neck. Thus, killing it.

It's large body thudding to the ground. "Eh!?" Inosuke landed on its chest, glaring at the dude who was one fire. It seemed to be apart of him. He didn't have a demonic aura, nor sounded like one. Even though he was huge.

The man came to a stop, examining the 'demon' Inosuke stood on. "Who are you two?" He asked, now seeing that the two teens didn't look like interns.

Nor had he ever seen them before. "Demon Slayers! Who are you!?" Inosuke snapped, pointing a blade at the hero. A little bit of shock resided on his face, " Pro hero: Endeavor..."

Keigo was awakened from his deep sleep by the constant vibrations in his hand. Groggily, he tossed the phone, not caring if it fell from the bed. He shifted, turning away from the bright screen of the phone.

When the texting vibrations stopped and a soft ringtone started to echo, he knew that he couldn't ignore it.

Sitting up, Keigo picks his phone up. The light from the screen blinded him slightly, but he was still able to see that it was Endeavor calling. Sliding the button, he answered with a yawn. "Hawks speaking..."

"I'm gonna need you to look into something." His alert voice made Keigo sit up in bed. "And what would that be?" A long sigh echoed from the other end. "Two of these kids were in Hosu last night... They killed a Nomu with little to no effort."

'Kids?' Keigo got up, stretching his limbs and wings. "Possibly defensive when spoken too?" Throwing on a sweatshirt, he walked out into his living room. Barely remembering to keep the blinds closed. "Yeah, did you run into something similar?"

He glanced at the room you two were supposed to be in but found it empty except for the few items they owned. "You could say that. Two kids dropped from the sky about 11:17 PM last night... They were at least 280 stories up. One of the injured while the other was being defensive as fuck over her."

Slowly, Keigo walked around, looking for the two teens. "280? How did they get up that far?" He sighed, clearly not knowing an answer. "You ask me, I didn't see a some type flying quirk on either of them." Keigo started his pot of morning coffee, holding the phone between his ear and shoulder.

"Anyways... They were close to where Shoto and his friends were battling Stain. One of them, a rather rash one saved a kid with green hair when one of the Nomu's snatched him. Quite loud... The one he was with, just kept whining and chasing after him."

Putting the pot down, he grabbed the warm mug. "Did he talk about demons?" He slowly took a sip of the warm liquid, tasting the flavor. "I believe so, kept calling the Nomus demons. Why?"

Keigo set the mug down, now seeing the three teens resting on his beanbag chair. "I think we may have found their friends... I've got something similar here... The male, was cautious of anyone with a strange appearance, seemingly a scent quirk being block by the amount of smoke." He walked over to them, looking down now at the three. Nezuko had joined the pile, cuddling between them.

"There was a third one with them in a small box on the Male's back... She doesn't seem cognitively aware of her surroundings and wears a bamboo muzzle." He explained quietly, as not to wake them. "So?"

"That's the issue, she's 14 looking girl fitting inside a box no bigger than a 4-year-old could fit in." Keigo walked away towards the kitchen.

"A shrinking quirk?" He asked, shifting around on the other end. "Hm, I don't think so, these kids don't seem aware of quirks at all. They carry swords and wear traditional clothing that is practically armor. They have basic skills that no one could master easily unless it's been done a million times over."

"The two here had swords as well, a matter of fact, I couldn't see any quirk usage at all with them, almost as if they didn't have one." Keigo sighed, knowing that the kids had some sort of ability, just not the definition of a quirk.

"No, I think they do. Just not in the way we're thinking of... Those words might be how they use or release abilities." He took a seat at the bar in his kitchen, resting his head in his hand. "They're so young, it takes years for anyone to master the sword like that."

"It does unless your life depends on it. When those kids came here, they were mentioning that they were fighting some sort of demon. Taking what I could get out of them, this one had the ability to create portals and launched them here."

"If these things eat humans... Could it have leaked here?"

"Possibly, I want you to keep an eye out for anything happening to people at night, and I want you to keep an eye on those two until I can get the others to them." He stared at the center of the empty mug. "I'll fill you in on what I find."

From there he hung up the call. 'Time to get going...' Taking his time, he hopped into the shower. You woke up to the sounds of whispering echoing about the room. Each word pulling you further into the awake mode. A firm heaviness pressed against your chest. Opening your eyes, you realized that it was just Nezuko.

"Oh... You're awake? Odd place to sleep but okay." You looked over just to see that it was Hawks. His hair dripping wet and a towel around his shoulders. Groggily you nodded. "Why are you wet?" You yawned. Keigo raised an eyebrow. "Never heard of a shower?" Carefully, you removed yourself from Nezuko and Tanjirou. "I don't think so...? Like rain or something?" Keigo motioned for you to follow. He led you to a room where you could see yourself.

Dirt splotches were scattered across your skin. This was the dirt that wouldn't ever come off without a lot of force on your end. Keigo opened a glass door, showing a tiled room. "Here, let me show you." (Dad mode activated XD) Once the "rain" came down from the facet, you were amazed. You guys had nothing like this back home. Not even close.

"Hold on one second." Keigo walked out of the room, leaving you there admiring the falling water. Steam poured from the door, sweeping across the tiled floor. A couple of moments later, he came back with pieces of clothing.

"Put these on, I'll stick yours in the washer. The Haori too, yeah?" You looked at him with concern. "No... Not that please." You stuck your hand underneath the water, testing it. It was warmer than a Lukewarm hot spring back home.

"Got it? I'll leave it to ya." With that, Keigo left. He was definitely starting to feel like a dad with these kids around. You began to strip the uniform you had grown so used to wearing. Once completely done, you stepped in. The hot water stung at your stitches. Ignoring them, you poked around for anything that seemed to be soap.

Not finding anything other than something called a 2n1. After reading the instructions on the back, you began to wash your hair. Rising was rather easy and afterward, the finesse of your hair grew. Now much softer than before. Using something else called "body wash" You began to clean yourself, the dirt being removed so much easier than before.

After some fiddling with the handle, you managed to shut it off. Everything with the clothes seemed to be okay and comfortable when you put them on. Pulling your hair into (hairstyle) you nodded at yourself in the mirror. Shyly you waked out, following the path that Keigo led you in. Holding your uniform close to your chest, you found the rest eating at a table.

"W-where do you want these?" You asked, now feeling shy in the clothes. Keigo and Tanjirou looked up, almost spitting out the pancakes in their mouths. "Just leave em there." He said, motioning towards the counter. "Your turn, Tanjirou, follow me." Keigo stood, leading the blushing teen into the bathroom.

Shyly, you sat at the plate that was set out for you and began to slowly eat. Feeling nervous, you decided to tuck your sword at your side later. When the meal was gone, you stood and walked into the room. Firmly attaching your sword to your side.

Walking out, you realized that Nezuko had gotten into a pile of clothes and was attempting to put them on. Smiling, you walked over to her and knelt down. Grabbing a few that would look cute, you lead her towards the guest bedroom.

After she was dressed, you decided to play with her hair. Carefully, you pulled it up into a ponytail, leaving two short pieces at the front to braid into it. She looked cute to you once it was all done. Nezuko's eyes sparkled at the outfit change.

"(y/n)?" Your head turned towards the sound of Tanjirou's voice. He was standing in the door way with the same type of style clothes you were in. "Hey..." You whispered, thinking about how good he looked.

Standing, you met the boy at the door. "I never did tell you how good you look, did I?" Tanjirou's statement caused you to chuckle lightly. "hm, thank you."

"You kids done flirting?" Shocked, you jumped back, your hand on the blade. Only now you realized it was just Hawks standing, by the door frame.

"Come on, you three are coming with me." Keigo motioned a hand over his shoulder, motioning for them to follow. "What for?" You asked, curious of why he would do that.

"I have something to show you." You and Tanjirou looked to each other before nodding in agreement.

Nezuko crawled inside her box while Tanjirou grabbed his sword. Once everything was ready, you followed hawks out the large building. With Nezuko on Tanjirou's back you were led outside. Curiously, you glanced around, trying to see the sky past the sky rise. "This way."

You glanced at the buildings turning into what seemed to be a neighborhood, then to a large building that seemed... to be made of Glass.

Large blue walls surrounded the area with golden letters on top. "U.A?" You muttered, trying to make sense of the place. Keigo sighed, "Its high school for Heroes in training." Instinctively, you slipped your hand into Tanjirou's.

"Sir, what are we doing here?" Tanjirou asked, gazing up at the walls. Keigo looked back at them a lazy grin tracing his lips.
