[ So, I was going through a very terrible writer block while making this, but I really wanted to update, so I'm sorry if this chapter is all over the place! I hope you guys still like it! ]

***

“Y/N-san, where are you going?” Naho approached Y/N in the next day.

“I'm going to see Daki! I'm a bit worried since she's been all alone with Nezuko since last night and all-”

“I-I see, good luck then!” The kid responded with a scared expression, running away just after.

'Everyone is still too scared to approach Daki, and well, it's not like I can blame then, let's just hope that she can get closer to them later-' Y/N thought as she approached the room where the two demons were staying, doing a small knock to announce she was there before opening the door. “Daki? Nezuko?”

What Y/N saw when she entered the room was something that she wouldn't ever expect to see.

Small Nezuko and small Daki were sitting in front of each other in the floor, Daki talking about something and Nezuko just responding with randoms hums.

'They're…. THEY'RE SO ADORABLE, WHAT THE HELL-'

“Ah, Y/N! Is everything okay?”

“Y-Yes! I just wanted to check on you guys, is everything okay?”

“Of course! Nezuko is teaching me about her energy recovery without eating human's technique!”

“Oh, and that technique is…?”

She put both of her hands in her hips and proudly puffed her chest. “I will explain it to you! First, you lay down.”

Daki said, laying on her back. “Then you close your eyes….”

“And?”

“And you stay there.”

'….so basically, she taught her how to sleep-'

“Huumph! Humpph!”

“Haaah?! What do you mean I'm doing it wrong?!” She sat up, her cheeks puffed in frustration.

“Wait- You can understand what she's saying?!”

“Huh? You don't?” Daki tilted her head, confused.

“Huumph! humph!”

“Huh? You need to lose consciousness for it to work? Why? Isn't that very inefficient in battle? Does your brother carry you in the middle of the fights because you're lazy?”

“HUMPH!!” Nezuko angrily started to give small punches to her shoulder.

“OKAY OKAY! I'M SORRY! LOSE CONSCIOUSNESS, I GOT IT!”

'pfft- They are so cute-'

“Y/N! Aoi was calling you for….” Zenitsu appeared, looking over the room before his eyes settled on Daki, his smile completely dropping to a fearful face in a matter of seconds. “GYAAAAAAAAH!!!  DEMON!!! WHY IS THERE A DEMON IN HERE?!”

He immediately grabbed Y/N, trying to pull her away. “E-ESCAPE! WE HAVE TO ESCAPE!!”

'Though I did tell Zenitsu that I would bring Daki with me, he was in sleep-mode at the time, and judging by his reaction right now seems like no one bothered to tell him about her either-'

“It's fine! Daki is a good demon now! Just like Nezuko!”

“hmm!” Nezuko hummed in response, Daki pointed at her and said with a nonchalant expression : “She said that you're a yellow-haired bastard.”

“WHAT?? HOW DID THAT SMALL 'HM' EVEN TRANSLATED TO ALL THAT??”

In response, Daki only looked at him with a blank expression, blurting out : “Cretin.”

“Hmm.”

“Coward.”

“Hmph.”

“Cry baby-”

“WAAAAAH!! Y/N PLEASE TELL THEM TO STOP THAT!” He grabbed the girl's shoulder, starting to shook her while crying.

“Daki, Nezuko, I know that he doesn't look very reliable and that he has a bit of a questionable personality, but you guys can't be mean like that you know-”

“are you defending me or putting me down even more?” Zenitsu murmured with an offended expression.

To Y/N's surprise, Daki and Nezuko are getting along quite well and seemed to even have formed some kind of alliance to hate on Zenitsu, though she couldn't tell whether that last part was a good thing or not.

'Well, as long as they don't go too far with their bullying-'

After some more minutes of talking, Zenitsu finally calmed down enough and stopped freaking out about Daki.

But it ended up being all fruitless, as something suddenly started to craw out from Daki's back like some kind of scene in a horror movie.

“GYAAAAA?! WHAT'S THAT-” He hugged my arm while screaming, and at this point, I'm starting to think that he grabs me by reflex every time something scares him-

“So noisy… what's going on?” Gyutaro said with an angry expression, turning to glare at Zenitsu.

That was Zenitsu's last straw, he passes out on his back, white foam coming out from his mouth.

“…. isn't that the person who fought against us back then? Why is he acting like it's the first time he sees me…?”

“Well, technically, that is the first time that he sees you-”

“...what?”

“I don't know how it works, but he fights while sleeping…? And he forgets everything that happens after, so be sure to introduce yourself properly next time!”

“…what?!”

“Fighting while sleeping? Humans are so weird… Ah! Besides you Y/N! Of course!” Daki said with a happy smile, hugging Y/N's arm.

“Hmm!” Nezuko hummed, going to hug her other arm.

'… I can't move-'

“I'm happy you guys are all doing well, but I should go check on whatever Aoi's was calling me for…” Y/N commented.

“Eeeh? Can't you stay more?” Daki said with a pout.

“Though I'm very tempted to stay here for the rest of my life, duty calls.”

Y/N commented as the girls let go of her with sad expressions, proceeding to grab Zenitsu arms and starting to drag his unconscious body away from the room.

“Brother, let me teach you how to use Nezuko's secret technique!”

“Hummph!”

Y/N closed the door, letting go of Zenitsu in the middle of the corridor and poking his cheek. “Come on, sleeping beauty, get up! I can't drag you around the house forever, you know?”

Responding to her complaints, he started to slowly sit up, Y/N waving her hand in front of his face with a frown. “Hey? Are you awake? Am I talking to normal Zenitsu or asleep Zeni- Kya!”

Seeing as how she was immediately tackled into a hug, seems like this is asleep Zenitsu.

“… I was worried.” He suddenly commented, his face hiding in her neck.

“Worried? About what?”

“Are you dumb?”

“Did you just call me dumb-”

“You really are an idiot. An idiot who doesn't think before acting. What would happen if Daki hadn't listened to you? Did you even think about that?”

'So he's talking about the red-light district battle?? oh, right! Though Zenitsu himself doesn't remember anything, his asleep-mode does-”

“I'm… Sorry(?)”

“You don't mean that apology.”

“…. Yeah. I don't.”

'why does his voice sounds so low when he's asleep, it's making me nervous aaaaaaa'

“You are always so reckless. Do you even think about how many people would be sad if you died?”

'damn, he really is lecturing me right now-'

“… I'm sorry.”

“Do you mean that this time?”

“Of course, I mean that!”

“It doesn't seem like you do.”

“I DO MEAN IT!”

“Then prove it.”

In response, she grabbed his shoulders, pushing him away from her to glare angrily at his face. “I PROMISE, OKAY?! I won't act recklessly in battle anymore!”

“Well, since you said so, you will be ready for the consequences if you break this promise, right?”

“Yeah!” She nodded very earnestly, before suddenly realizing something…

'…why do I feel like I just sold my soul to the devil…?'

“… Heh.” He smirked.

'He- He tricked me! Sleep-mode Zenitsu is dangerous! Too dangerous!'

“Jeez, you made me think you were angry with me, you cretin.” She mumbled.

In response, he just silently took her hand, kissing her knuckle while staring directly at her eyes. “Sorry.”

Y/N was so used to seeing him screaming or crying, that the fact he was gazing at her so lovingly and with such a serious expression probably had a bigger effect on her than it was supposed to.

She didn't know how to respond. She froze. Literally.

“I- Uhm, I- A-”

'WHAT I AM EVEN SAYING-'

While Y/N was tumbling in her words, he just looked at her with a small smile, he really was having fun with this, huh?

In the middle of her embarrassment, she ended up smacking his face by reflex. “Ouch!”

“…ow, what was that for?” Zenitsu commented, rubbing his swollen nose.

“Ah! I'm so sorry! I didn't mean to hit you! It's just that you really took me by surprise and-”

“….uhm? Y/N? Why are we in the floor?" He asked, confusedly looking around with a frown.

'Oh- Seems like my smack woke him up-'

“… It's nothing.”

“Really? I feel like I should remember some-”

“Didn't you say something about Aoi calling me before?” Y/N cut him.

“Oh, right! She was calling you for lunch!”

“Really?! Let's go then!” She excitedly got up, grabbing Zenitsu's hand to drag him to the place.

“I can share my part with you if you want!” He said, smiling happily at her, you could almost see the puppy ears and tail on him.

Y/N stopped walking to stare at him with a shocked look. 'Incredible. It's like a total different person! Is that really the same guy who tricked me and kissed my hand?'

“Uhm… Y/N? Is everything all right? You froze.”

“Ah- Yeah! I'm fine! Let's go!” She said back, starting to walk again and opening the door of the dining room.

“Good morning everyone!” The girl exclaimed, quickly sitting up in front of her food tray. “Thanks for the food!”

She was about to eat one of the tempura, but someone suddenly kicked the door, making her drop her chopsticks from fright. “YYY/NNN!”

“Suma?!” The girl ran up to Y/N, hugging her.

“THERE YOU AREEE!”

“Suma, stop making a mess!” Makio ran through the door, Hinatsuru following with a worried expression.

“Ah! It's Uzui's wives! What are you guys doing in here?”

“Huh? Can't you see it? We are obviously staying here to recover, of course!” Suma said, nuzzling against Y/N's arm.

“….TANJIRO, THEY ARE LYING! THEY ARE ALREADY RECOVERED! I CAN HEAR IT!”

“Y/N-san, you should eat more!”

“Here, say ah~”

'When did Y/N and his wives got so close...?' Tanjiro thought, in complete shock.

“You get used to this after a while.” Uzui, who has been standing there since who knows when, commented behind Zenitsu and Tanjiro.

“GYAAAH! It's this weirdo again!!” He received a punch to the gut in response.

“Y/N, are you really going to stay in the corps?” Hinatsuru said worriedly, patting her head.

“Eeeh?! You're staying here?! You should marry us instead!” Suma said, hugging her more tightly.

“MARRY?! Y/N IS NOT MARRYING THIS WEIRDO!!” Zenitsu exclaimed, taking her away from the three girls.

“Hah?! Who are calling weirdo?!” Uzui entered the fight, taking Y/N from him like she was a rag doll.

'I just wanted to eat-' Silent tears were seeping out from her eyes.

“My rivals… keep increasing-” Tanjiro mumbled, you could almost see his soul disintegrating, hang in there buddy.

“Stop with the screaming! There are other people recuperating in here, you bunch of morons!” Aoi exclaimed, everyone immediately shutting up and gloomily going back to eat.
