☁︎︎ Third POV

Y/n yawned as he sat next to Inosuke. Today he had to wake up a bit earlier than normal because he was attending training with Tanjiro and Inouke. Today marks the first day of training for Y/n and Zenitsu, who didn't look happy at all.

"Zenitsu-San, Y/n-San, you're both taking part in training starting today!" Aoi, one of the butterfly girls stated, "So let me explain it to you!"

Aoi went on explaining the different types of training exercises that Y/n and the others will be doing. To Y/n, it seemed simple and he thought that Inosuke and Tanjiro were just overreacting that one time.

There was going to be stretching, which the three butterfly girls are going to do, than a simple reflex game, and an intense game of tag. Y/n slightly tilted his head and the simplistic exercises, with how Inosuke and Tanjiro were acting he thought it would be much more tougher than this.

"Sorry, can I ask something?" Zenitsu stated with an agitated look on his face.

Y/n looked at Zenitsu from the side of his eye as he raised a brow. Tanjiro and Inosuke hung their heads down in tiredness.

"Is there something you don't understand?" Aoi asks.

Zenitsu got up from his position, "No, just... Tanjiro, Inosuke, come over here."

"Not going," Inosuke argued and Tanjiro looked up in questioning.

Y/n shuffled a bit away from the trio, seeing how Zenitsu's wavelength changed from his domineer change.

"I'M TELLING YOU, SCREW IT AND JUST COME HERE!!!" Zenitsu shouted startling everyone, "COME DAMNIT!! PEICES OF SHITS!! TRASH!!" He started to drag Inosuke and Tanjiro away and slammed the door shut.

Y/n sweatdropped as Zenitsu's yelling could be heard even with the door close. He turned back to the girls, who were a bit startled by the sudden yelling.

"May I start my training while they're at it?" Y/n asks politely.

Aoi snapped out of her slight daze moment and turned to Y/n, "Sure thing, let's get you all stretched out."

Y/n nodded and went over to the three butterfly girls. The three helped Y/n stretched out a bit but Y/n was already stretched from some reason. Aoi even had to help the three girls a bit because of how flexible Y/n was.

"Y/n-San, have you been stretching on your own time?" Aoi asks.

Y/n nodded slightly, "Well, not really, just simple ones."

Aoi huffed at this and lightly punched Y/n's head, "You were supposed to be resting. Next time you're here because of an injury, you better be resting instead of training. I better not even be able to bend your leg all the way to your head like this!!"

Y/n softly rubbed the spot Aoi hit, "Hai, sorry, I'll make sure to take better care of myself next time."

Aoi crossed her arms, "You better. Anyways, since you're stretched out now, how about you go up against Kanao-San."

Kanao perked up from her name being called. She thought that Y/n was going up against Aoi first than her. But of course she didn't say anything, she just kept her pointed smile on her face.

As Y/n was being seated on the other side of Kanao, the trio finally walked in and was ready for their training now. To which, Aoi had them start immediately with stretching which caused them a bit of pain.

Y/n and Kanao watched as the three boys stretched, waiting for Aoi to be finished with them so that she could tell Y/n and Kanao when to start or not. The two sat in small silence which wasn't uncomfortable for either of them.

"Alright! Y/n-San, Kanao-San, are you ready you two?" Aoi asks, walking over to the older two.

As the trio were resting a bit from stretching, they watched Kanao's and Y/n's interactions.

Y/n's nodded as Kanao did the same. They both faced each other and looked down at the cups, focused and not saying a word.

"3, 2, 1, and go!"

Immediately Y/n was splashed with the medicine water. He blinked a bit in surprise of what had happened. Tanjiro, Aoi and the others were surprised too.

It happened super fast that no one else in the room could even comprehend what happened. Both Y/n and Kanao were moving so fast, moving and putting down cups, stopping each other's hands and before anyone knew it, Y/n was splashed.

Y/n slightly narrowed his eyes, "May I try again?"

"U-uh, s-sure!" Aoi stuttered.

Y/n was given a towel by one of the butterfly girls, to which he was thankful for and patted her head. The cups were rested and Y/n turned to face Kanao again.

"H-Hold up!! They're both too fast!! How are we supposed to go up against her?!?!" Zenitsu cried out.

Aoi ignored the blonde and stepped back from the 'splash' zone, "3, 2, 1, and go!!"

Medicine water dripped from someone's hair. Everyone's eyes widened at the speed Y/n and Kanao had went. Kanao eyes were widened because she was splashed this time and not Y/n.

Kanao looked up - water dripping from her hair - and at the cup that was aimed at her. The cup moved a bit and showed Y/n with a pleased look in his eyes. Kanao blushed a bit at Y/n face and her eyes expanded a bit more.

"Gotcha," Y/n said with closed eyes signaling that he wanted to smile.

Aoi's breathe stuttered from shock, the butterfly girls were whispering a bit to each other, and the boy trio were in shock as well. The trio's eyes shined at how fast Y/n was, it was unseeable and amazing to them.

Y/n got up from his seating position and gave Kanao his towel. Aoi stuttered a bit more and went up to Y/n and started to talk to him, telling him what will happen next after he rests a bit.

"Wow..." Tanjiro whispered out.

"Amazing..." Inosuke breathed out.

Zenitsu glanced at the two boys beside him. His brows slightly furrowed a bit as he heard their heartbeat raised a bit, as if they were love sick or flustered. He turned back to Y/n who was talking with Kanao and Aoi, he could even hear Kanao's heartbeat raising.

Zenitsu glanced at the two beside him than back at Kanao. He turned to Y/n who looked relaxed at the moment sitting on the ground per Aoi's request.

'Just how many people did you make fall for you Y/n?' Zenitsu thought to himself, 'I know I'm one of them though...'

☁︎︎ Time Skip ☁︎

Y/n sat in the middle of the room he was led to. He was currently at Ubuyashiki's estate since he had requested for Y/n to come here for a small talk that he wanted to have.

As Y/n waited for someone to enter the room or for him to be called, he couldn't help but feel a bit awkward. He didn't really like being in someone else's estate or home without them there with him, it just feels wrong.

The feeling of someone's aura caught Y/n attention. He turned to his side and noticed a young child with black hair peeking from around the door. Their - Y/n could now tell that the child was a boy - he's aura was a blue-purple color with nervous wave lengths.

"Hello, you're from Final Selection right? What's your name?" Y/n asks in a warm and comforting voice.

The boy nodded to the first question, "M-my name is Kiriya, You're the guy that helped my sister, th-thank you for that..." He stuttered a bit.

"Ah, of course, how is she doing? Was she alright after what happened?"

The boy nodded shyly, "She's alright now thanks to you."

Y/n let out a small hum, "Well, you can come out of there. Is it just one of you?"

White hair poked out of the other door. Y/n raised a brow.

"Two of you?"

A pair of purple eyes peeked over Kiriya's shoulder.

"Three of you??"

Anohter tuff of hair peeked over Kiriya.

"Four of you..."

And finally a pair of purple eyes peeked around the door and over the first tuff of white hair.

"Ah, five of you, are you sure that's it?" Y/n slightly joked.

The girls smiled a bit at Y/n and Kiriya's eyes shined a bit in appreciation. The children giggled to themselves a bit, them already warming up to Y/n.

One of the little girls stepped out of line and out of the door frame. They other kids watched their younger sister walk up to Y/n with a nervous look.

"You must be the girl in Final Selection," Y/n stated, "We're you okay after? Did you heal nicely?"

The girl fumbled with her kimono a bit, "I-I'm Kanata, an-and th-thank you for that day..." She stuttered.

Y/n blinked a bit before closing his eyes in a happy manner, "Of course, Kanata, I didn't want you to get too hurt, your health is important."

The Kanata's eyes shined. She let a smile take over her lips and engulfed Y/n into a hug. Y/n was caught by surprise but soon hugged Kanata back. The other kids saw this and smiled too. They all came out of their hiding spot and surrounded Y/n with smiles and hugs.

The kids asked Y/n questions about being a slayer and how his life was. Y/n answered the best as he could while holding Kanata in one arm and Kiriya in the other. Although Y/n couldn't smile, the kids knew that Y/n was happy.

The kids talked and played with Y/n, telling him their names and their parents names and what they've been through. No one went out of bounce and were very respectful with each other.

"Ah, what's with all the noise in here?" Ubuyashiki asks with a smile on his face as he entered the room with the help of his wife, Amane.

"Father!" The kids claimed in a surprise manner.

"Oyakata-sama," Y/n stated, "And Amane-sama."

Amane was shocked that Y/n knew her but she shook it off and smiled towards Y/n in gratitude. She helped Ubuyashiki to sit and went to softly push her children out of the way.

Kiriya didn't budge however and lingered behind, "Bye-bye Y/n-nii-San, please visit us soon!" He claimed as Amane softly pat his head.

Y/n gave Kiriya one last hug before softly pushing him towards his mother, "Of course I will, Kiriya, now go, I promise to see you soon."

Kiriya smiled and quickly followed behind his sisters. Amane smiled down at Y/n and nodded as a thanks to him and left. She softly closed the door and went off on her own.

Y/n let out a soft sigh and turned to look at Ubuyashiki, who had a soft smile on his face.

"The kids seem to like you, huh, Y/n," Ubuyashiki said.

Y/n softly hummed, "It does seem so. They are very nice, respectful too, it rare to see that now a days," He stated.

Ubuyashiki laughed a bit, "Is that so? Ah, well, I do want to thank you for making them smile. I can hear it in their voices that they love spending time with you."

Y/n looked down slightly, "Yes, they do, surprisingly..."

There was a small silence before Ubuyashiki let out a soft sigh and turned to where Y/n was. The sigh caught Y/n's attention and made him look up at the older.

"I requested you to be here to ask you a question, and I just want to make sure that this is what you want, is that alright?" Ubuyashiki said.

"Yes, what is it that you need to know, Oyakata-sama?"

"Are you sure you don't want to become a Hashira? You could benefit from it by a lot, you have the speed and strength to be one, not to mention you have met the standards for becoming one."

Y/n looked down slightly but soon looked up, "Yes, I'm sure I don't want to become a Hashira. Sure, I may seem capable to be one, but I think I'm going to fast for other, and I still want to stay by Tanjiro-San's side a bit longer."

Ubuyashiki let out a soft laugh, "I figured you'd say that, and that's okay, Y/n. You don't need to feel bad about it. You are dismissed, you can go ahead and go back to the butterfly estate."

Y/n nodded and got from his seating. He went over to the door and was about to open it but paused when Ubuyashiki started to talk.

"And Y/n?"

Y/n glanced back, "Yes, Oyakata-sama?"

"You should stop doing that to yourself. Live long, Y/n, people - other than Tanjiro and Nezuko - want you to stay," Ubuyashiki said, not looking at Y/n but smiling.

Y/n glanced away and down. He softly held onto his forearm in slight worry and wonder on how Ubuyashiki knew about him. He only opened the door and said nothing while closing it behind him.

Ubuyashiki heard the door close and his smile dropped after not hearing Y/n's response. He knew what Y/n was going through, but he also knew that he can't interfere much with what Y/n does to himself.

"No luck?" Amane asks, helping Ubuyashiki up.

Ubuyashiki held onto his wife arm, "We can only hope that he lives on. But I have a feeling that he won't survive for much longer, and the death won't be caused by himself but there is a chance for that to happen."

Amane looked at her husband in worry as she led him out of the room, "He's such a sweet kid, poor thing going through so much stuff all by himself."

Ubuyashiki's eyes lowered, "Yes, he really is such a kind and sweet kid, it's unfortunate..."
