"And this should be it."

Yaya muttered as she tucked in her patient in bed. As a nurse, she must do what she can to give these poor souls great medicated care.

She wiped away some sweat off her forehead as she had been at it for at least 2 hours. Having to take care dozens of Demon Slayers who were gravely wounded seems exhausting if continued for prolonged periods of time especially if she had some help along the process.

The other nurses, namely Sumi Nakahara, Kiyo Terauchi, and Naho Takada, are really young to be able to give treatment to the patients. But with enough teachings from Shinobu herself, they all started working independently albeit in their own little group.

After she learned that their families were slaughtered by demons, she can't help but to give them her sympathies for the loss of their loved ones. Her head hung low after she reminded herself that she is now in a world where man-eating beings roam at night time, looking for their meal in their ravenous nature. She was utterly terrified to be put in this situation considering all of this was fairly new to her.

But after two years when Shinobu first found her, she taught Yaya how to defend herself as well as giving essential advices in medical experience. Afterwards, she dedicated herself to train her mind, body, and soul. Shinobu had acknowledged her motivation to become stronger so she offered her an opportunity to become her Tsuguko and continue to train her.

Yaya complied.

in amidst of her training, she had discovered a new power that she never thought she had gotten in the first place, even Shinobu herself wasn't aware this might happen. Yaya played around with her new-found Breathing Technique and tested out it's abilities in battle against anything around her.

She will call her breathing as Petal Breathing.

Shinobu questioned her decision of naming her Breathing Technique as her breathing is eerily similar to Flower Breathing. She ultimately approved when Yaya proved it to her by testing it against a lone demon who happened to be nearby.

She eventually met Kanao whilst in her training. When she first met her, she thought Kanao was a mute, silent type. Until Shinobu explained her of Kanao's past, Yaya felt sorry for the girl's traumatic experience.

After all her training as Shinobu's Tsuguko, she was gifted herself her new Demon Slayer uniform. Yaya appreciated it and gotten herself her own haori as a pleasant bonus.

Occasionally in her nursing days, she often wore a nurse dress with her standard Demon Slayer outfit beneath it. Similar to what Aoi wears.

Even after training as her Tsuguko, Shinobu had instructed her to take part in Final Selection where she can be determined by her rank as a Demon Slayer and sees if she can hold her own against demons. As expected, she completed the trial and was ranked Mizunoto along with the surviving Demon Slayer and was gifted a Kasugai Crow then her sword's ore next to be forged.

Her missions were usually solo or duo with Kanao. The amount of missions they partaked in were impressive to some Demon Slayers as they get the job done. An impressive feat approved by Shinobu for training Yaya well.

"I need some fresh air..." Yaya sighed. A break would suit her need for recharging herself after doing much work for today. 'I'm sure the others would know that I'm gonna be taking a break.'

In the span of two years, she couldn't come to bring herself to know that she is placed in a complicated situation. She kept telling herself that this is all a dream, a bad dream, a nightmare. And that she would wake up one day to find herself surrounded by her friends and asking her if she is alright.

Sadly, that didn't come into life.

She would cry herself to sleep, stare into the abyss of her own self and said to herself if this was all meant to be. Even after trying to set everything into the back of her head, she would often breakdown and sob.

Her home.

Her family.

Her friends.

All gone.

'BoBoiBoy...'

Despite of what she heard and saw last night, she refused to believe what she had resonated in her ears and seen with her own two eyes. She told herself that she is slowly becoming insane that everytime she hears a word, her friends, mostly BoBoiBoy's name, would always come crawling in the back of her mind.

But had she paid any attention to what the crow said last night, then she would've approached the unknown Demon Slayer and examined them up close. On the other hand, it would just be someone she doesn't know.

She tried so hard to forget about it. She really did.

It somehow did work, but it's short-lived.

She distracted herself by tending to some patients. It did the best to get her mind off of the events last night. A content face plastered on her round face proved it. She wanted some respite from having her mind twisting in sorts of ways she can't make sense of.

'Please let it be you... Please...'

As time lived on, she'd wish she see BoBoiBoy or any of her friends one last time. She had always believed that one day, that there will be someone who will wake her and sees BoBoiBoy, telling her that everything is just a bad dream and lead her to her friends all waiting for her to start her day.

Her hope was shining for months. Sadly, her hope slowly dimmed as time went on.

She was about to turn to another corner when footsteps caught her hearing range. It could've been anyone but she called out.

"Aoi? Is that you?"

The footsteps stopped and a gasp was heard. That came off as strange for her.

"Aoi? Or is that you, Kanao?"

Again, no sudden movements or a reply, almost as if that person was in a trance of something.

"Is everything all ri—"

As if time had slowed down around her, what she sees with her own two eyes completely threw her off guard. Every feeling she had welled up began to resurface. It's unmistakable.

"B-B-BoBoiBoy...?"

Her voice was shaky and is having difficulty in controlling her tone. But she didn't care at that point.

"Y-Yaya...?"

His voice was the same as well. One thing she noticed about it is how a little deep-sounding it was to her.

Neither of them said anything and let their actions speak for them. BoBoiBoy still stood in his spot, paralyzed at what is in front of him while Yaya took the initiative of stepping forward to cup BoBoiBoy's cheek with her hand to make sure if he's real or a figment of her imagination.

Once her hand felt the contact she would expect, that's when she knew the crow's announcement is real and the whole time she thought he wasn't real, she was wrong. Yaya bursts into tears and immediately tackled BoBoiBoy in a heartfelt hug. She snaked her arms around him tightly and never lets him go with every fiber of her being. BoBoiBoy, tears leaking from his eyes, found his senses after the sudden contact and hugged her back in the same manner as her. They continued their moment of solitude in their arms while their sobs were the only sounds they can hear at the moment.


They sat a bit awkwardly on the porch where BoBoiBoy sat and contemplated about his life. Yaya stared at the side while trying her best not to meet his gaze. Their eyes were red from crying and they needed some space to clear their clouded thoughts from each other. Yaya had a shadow of a doubt but this is still all too surprising for her.

BoBoiBoy had never expected to meet with Yaya after two years had passed. He had a sneaking suspicion when he heard a sound that hits him close to home. He never gave much thought that it would be Yaya. BoBoiBoy slapped himself mentally for not realizing it sooner.

"I..." He heard her speak for what seemed like forever. "I never thought I'd see you again..."

She almost choked on her words.

"M-Me too." BoBoiBoy responded back. "Yaya, I... I thought so too..."

Yaya mustered up the courage to look at him straight in the eyes. His brown orbs were piercing her own hazelnut orbs and she found herself trying to compose herself but failed miserably.

"I'm so happy to see you... After all this time." She said. "I thought I was the only one."

"I thought I was the only one as well!" BoBoiBoy spoke a little loud. "I keep thinking that I might never see you or our friends again! But thank goodness! I'm not alone anymore!"

"Really?" Her eyes widen. "It must be really sad, to know that we have not seen each other that much. It had been two years since I've been here."

That got his attention. "Two years? So you're just like me."

"You too?" Yaya was surprised. "I...I didn't expect that."

They went silent again, not knowing what to continue after that. It was still a shocker for both of them. But as it says, you can never expect the unexpected.

BoBoiBoy broke the ice. "So uhh... How were you doing these few years?"

Yaya smiled for the first time. An action that made BoBoiBoy's heart skipped a beat.

"I'm doing fine in most cases." She answered. "How about you?"

"I've been doing... fine." He didn't know if fine was the right word for himself but it's the most appropriate. "It was pretty lonely these few years. No matter how I try to forget, the memories of you and everyone back home just breaks me. Even if I had Tanjiro or my friends here with me, I feel like I was missing something important."

"I think I know what you're talking about." Yaya picked up on it. "I know it is pretty sad that it had to be this way. I had a bad time setting myself here these past few years. I still am but I'm trying not to let it affect it."

"I'm sorry to hear that, Yaya." BoBoiBoy affixed a sad look at her. "By the way, what do you do in the last few years?"

Yaya inhaled then exhaled. "Two years ago, Lady Shinobu had trained me to become her Tsuguko. You know what a Tsuguko means right?" BoBoiBoy nodded and urged her to go on. "She trained me so that I can become a Demon Slayer because the first time I heard of it, it terrified me. And when she elaborated it a bit further, I'm really scared to go out at night." She put her hands on her legs.

"It surprised me as well. When I heard that demons existed, I can barely hold in my breath." BoBoiBoy shared. "I also trained to become a Demon Slayer like you as well."

"We really had it going with us preparing for what's coming." Yaya lighten up, earning a light chuckle from BoBoiBoy."

"This reminds me, where did Lady Shinobu find you?"

She replied. "She found me in a forest that night. I couldn't remember where because it was really dark and I was hurt at that time. And because of that I was... I was..."

Seeing her hesitate, BoBoiBoy leaned closer. Yaya scooted to the side to make sure his body didn't collide to her side.

"I was attacked by demons. I tried to fight back but then I realized that my power band was missing. This meant I have no power to defend myself. I almost got killed if it weren't for Lady Shinobu who happened to be nearby while she was on a mission."

Yaya gaze down to the ground. A frightened look casted mixing in with her eyes, shaking in terror.

"I-It was s-scary... I can never f-forget th-those faces when th-they said I w-was their next m-meal..."

She stuttered along the lines. BoBoiBoy can clearly guess she's suffering from a traumatic experience of almost being devoured by these ravenous beings. He imagined himself in her shoes and he would've been placed in the same position as her. Throughout his time doing missions with Tanjiro, he was scared at first but grew to be brave as time went on.

To Yaya, however, she was utterly afraid.

"So that's why you chose to train with Lady Shinobu."

Her reply was immediate.

"Yes. I wanted to prove myself that I'll handle any demon that would come and attack anyone. At the same time, I wanted to become stronger and protect those I really care. I wish I was stronger back then when we were still together as a squad. Do you still remember, BoBoiBoy?"

"Remember what?" BoBoiBoy said and tilted his head.

"Remember that you always protected us? When we needed you and you'd always be there to save the day? You were our everyday hero as you kept saving us from time to time. That is when I realized, we were too weak to even fight beside you..."

His eyes widen. "Y-Yaya! You know that's not true!"

"It is!" She fully faced. He was thrown off-guard from her outburst. "Think back of how many times we tried to save you from time to time! But only for you to come save us in the end because of how we can't handle one simple enemy we faced! Like Ejo Jo, like Bora Ra, like Captain Vargoba, and Retak'ka!"

BoBoiBoy hung his mouth open and thought about it. With everything happened to them, it dawned on him that he was always the one saving his friends when they themselves couldn't. Despite the amount of times they prevailed, it wasn't them that fully finished what they've started. Like Yaya said, in the end, it was all BoBoiBoy that received the full glory.

She continued. "I'm sorry about this BoBoiBoy." She was about to stand up and walk away from him until she felt a hand gripping on her own.

"Yaya... Please don't say that anymore." He pulled her back down to sit right next to him again. "I'm sorry to hear what you and our friends have gone through and I can understand that. You guys are what kept me to move myself forward and I did it to protect you guys. I didn't consider the thought of claiming all the victory but I did it to save you guys. I don't want to see you all get hurt anymore."

He whispered. "Including you..."

Yaya heard it and she flushed a red tint on her cheeks.

"But my point is, you were strong in spirit, willpower, and courage. You hadn't given up your hope for me and I'm really grateful for that. If it weren't for you, I wouldn't have probably be here with you right now. And... I just wanna say thank you."

His words have made an impact on Yaya as her lips quivered and eyes never looked away from his gaze. And it was at this moment, BoBoiBoy realized he said it to her and not just the rest.

"Aaahhh! But of course, it was also our friends that were with us from the start as well! Without them, then I couldn't have been the person they wanted me to be so—"

A body lurched forward to him and arms wrapped around his neck. A head was placed right beside and he could feel the wetness of liquid dripping down behind his right shoulder. BoBoiBoy's eyes widen when he sees Yaya instinctively embracing him.

He just let it happen and followed the same gesture back at her. This time, with more care than before.

"I missed you, BoBoiBoy! I missed my family, our friends, and everyone back home! I missed them so much!" She sniffed.

"I... I... I..." He couldn't hold back. The feeling was mutual. Everyone they knew back home. They can't reach to them anymore.

"I... I missed them too, Yaya..."


The sun is beginning to set as Tanjiro finally sets the box down to a vacant room. He was very thankful that they would allow Nezuko to have her own room a distance from others. It was a real breather.

He went to the window curtains and closed them off to shield the sun's rays from penetrating any further in the room.

"It's all right now." Tanjiro turned around to stare at the box. "They said you could use this room, Nezuko."

He proceeded to sit on the side of the bed when his internal injuries ignited and made him grunt in slight pain. It wasn't a complete recovery to him as it will be all healed in due time save those to the ones who were taken part of the mission in Mt. Natagumo.

He heard a knock coming from the door and he turned his head to the source of the knocking.

"Who is it?" Tanjiro asked to the receiver.

"It's me, Tanjiro. Can I come in?" It was BoBoiBoy's voice that came from behind it. Smiling, Tanjiro said it was all right to let himself in and BoBoiBoy closed the door behind him.

"Hey BoBoiBoy. You look down today. Did something happen?" Tanjiro curved his lips downward as he sees BoBoiBoy's frown on his face. BoBoiBoy walked closer between the dark redhead and Nezuko, who opened up her own box.

"I finally found one of my friends here. It turns out that she was actually working as a nurse here in the Butterfly Mansion." He told him of his encounter with Yaya and how they finally unite after so long.

"That's good!" Tanjiro exclaimed. "Then that means that you can find the rest of them knowing one of them is here!" Tanjiro cheerfully said to his brother figure. BoBoiBoy couldn't help himself but be anxious and excited at the thought of finding the rest of his friends here in this world.

But the other part of him tells him otherwise. Chances of locating the rest of his other friends are very slim. Yaya had explained herself earlier that she also didn't know what caused herself to be sent here in the Taishō Era of their world. That very little information alone didn't spark a clue inside BoBoiBoy's head as he knew he wouldn't be receiving answers soon as he and Yaya are starting from scratch to how they both got themselves here.

"Let's just hope so, Tanjiro. I don't want to alarm you but I think our situation of being here is getting a bit complicated than I thought. I just hope that I'll find an answer to this soon."

"I have faith in you, BoBoiBoy. I do. If there's anything you are having trouble with, don't hesitate to come to me and I'll try my best to help" It's only a simple sentence yet it made BoBoiBoy smile brightly. To know someone who highly believes in him is his epitome of hope and belief.

"Thanks Tanjiro." He then looked at the other Kamado sibling, who stares at him with her pink eyes the whole time.

"Hey Nezuko." He went over to her and pats her on the head. "How are you doing? Are you okay after... what happened earlier?" BoBoiBoy flinched at the last part. He even heard Tanjiro grumble something angrily after seeing Nezuko stabbed multiple times.

"Hmph! Hmph! Hmph!" She responded with incoherent sounds but both boys were able to understand judging from her facial expression. Her eyes beamed at the white-streaked boy and she ruffled his hair playfully.

"Easy, Nezuko!" He laughed as she continued playing around with his hair. Tanjiro still had his smile as he watched them going at it like they were actual siblings. It reminded him of his late siblings just from this scene alone. His smile slowly faltered as his memories of his family centered in his head. It wasn't easy letting go of his family's death but he had to stand up for Nezuko and protect her like a big brother should.

After they were done with their little fun, BoBoiBoy sat beside Tanjiro and gave him a pondering look. "Is there something on your mind?"

Tanjiro was in deep thinking that he didn't hear him nor see him.

"Tanjiro?" He waved at his face. "Tanjiro!"

"Huh?" He snapped back to reality and turned to look at him.

"Are you alright? You spaced out and worried me."

Tanjiro grinned. "It's nothing. I'm just thinking about some things."

Thanks to BoBoiBoy's sense of hearing, he noticed his sad tone when he said it. "If you don't mind me asking, is it something about your... family?"

"How did you...?" Tanjiro acted out of surprise.

"Hey, my sense of hearing, remember?" He gestured to his ear with his finger and told him. "If you don't wanna talk about it, I understand."

Tanjiro said nothing in return but decided to anyways. "Yeah. I was thinking about my family. I know it had been two years since they were gone but I still missed them. I'm sure Nezuko misses them even if she's under a hypnotic spell. Seeing you two play around with each other just makes me feel both happy and sad somehow."

The other boy shares his feeling of empathy to his family and to his own. It's still painful to know Tanjiro that he couldn't fathom the thought of losing his family too soon than he expected. With his surviving sister that became a demon, he had no one but him and his sister to be called family again. That soon changed with BoBoiBoy around. Tanjiro would've given up hope and lose all motivation to train to become a Demon Slayer if it weren't for the white-streak haired boy by his side at all means.

"Wanna hear my story, Tanjiro?" BoBoiBoy figured telling him of his story would soothe his conflicting mental pain in his heart.

"Hm? Your story?" Tanjiro tilted his head. He didn't know why he would tell him this now. Perhaps seeing him in this state prompted BoBoiBoy to expand more of his private life to him.

BoBoiBoy nodded.

"Sure." In his mind, it'll be a good opportunity to learn more about his origins better.

"It all started when I was still little. I remember when I used to play with my dad back home. We used to play pranks on Tok Aba, my grandfather, when I was still a little boy. My dad, well, he was the best dad I've ever known. When I was still 5-years-old, I drew silly little things on the walls of our house and my dad had found out about it. I was seriously thought he was going to scold me or ground me but instead, he just went along with it and joined me in my little adventure. It was very fun when my mom also found out and scolded us for making a mess around the house. Dad got an earful and I was grounded in my room for a week."

Hearing him doing mischievous acts made Tanjiro laugh and he continued.

"Then one day, when I was 10-years-old, he sent me to visit Tok Aba and told me to stay with him for a few weeks because he said he had some business to attend to and he might not get to spend enough time with me, not even my mom because she was busy with work. By the time I was 11, I went back home to the city to live with my parents again. Dad wasn't around but mom was still there. I asked her where he is but she didn't tell me. She then told me to start living with Tok Aba and let me attend school there because she thought I would be comfortable away from home and I would meet new friends. I still didn't understand why she let me stay at Rintis Island. I still didn't know until this day."

He sighed to let Tanjiro process his 1/4 of the story in his head. There were some things unclear to him, such as the basic terms like school. He wouldn't blame him for not knowing the meaning of it since he lived in the mountains his whole life. After explaining it to him quickly, BoBoiBoy continued on.

"Too many things happened when I first attended school. I met with my old friends again and made a rival named Fang. But as time went on, he and I were friends but he still think of me as a rival because of one goal he was always dreaming of getting. Do you wanna know what he dreams of getting?"

Tanjiro saw his playful grin. "What was it?"

He answered.

"Popularity."

The white-streak haired boy laughed while Tanjiro just chuckled, not entirely sure why he wanted it as an aspiration but he was BoBoiBoy's friend.

"But besides that, there were just too many threats that happened even after I first got to school. Seems that my presence around really attracted some bad guys like Ejo Jo. Ejo Jo is an alien from Ata Ta Tiga, a planet which aliens where Adu Du, who is also an alien and my former and current enemy, lived."

He paused to give Tanjiro a moment to sink this one in. Something about mention of another planet made Tanjiro wonder how much BoBoiBoy has seen throughout his modern time and what other possibilities there was out there in traveling to different planets. Tanjiro sometimes envied BoBoiBoy for being ahead of his time.

Nezuko crawled out of her box and plop herself down to the bed where she can listen to his story better.

"Trust me Tanjiro. In my time, it was a bundle of events that nearly costed my whole world if it weren't for me or my friends." BoBoiBoy said.

"But to start off in a young age, you are setting yourself in most danger! Especially your friends!" Tanjiro almost exclaimed.

"I know, Tanjiro. It's called being responsible. No one can tell us otherwise, but even if they did, we still do what is best for everyone's safety. What matters is making what is right for saving innocent lives."

'Wow... you weighed so much responsibility on your shoulders. I hope you know what you did is best, BoBoiBoy.' Tanjiro thought.

"Now where was I?"

"You said something about the Ata-whatchamacallit planet?" Tanjiro stumbled on the wording. BoBoiBoy snickered at his attempt to say the word.

"Ahh right! And it's Ata Ta Tiga." He said it slower to emphasize the pronunciation. "Like I said, with me being there, I'm exposing my friends and everyone in real danger. Ejo Jo was a tough enemy to deal with, even in my secondary tier forms aren't a match to him. We did beat him with some help but he retreated before we can finish him. Many months passed and we were on vacation after school ended. I did most of my time fighting crime around the city that I don't find the time to take a break and let stress overtake me. Because of this, it naturally awaken the hidden element I never knew I had inside me, BoBoiBoy Fire."

"I thought you didn't have that element when you said you didn't?" Tanjiro called something out.

"I did. The form is like a second generation element. So it didn't count as new to me when I already got it here." He explained. "My Water form also counted as second generation."

"I see." Tanjiro mused. He could learn so much from BoBoiBoy of his forms.

"After I got my forms, we met Fang's older brother named Kaizo. First, he stole me and my friends' power watches, including Fang's because he said we were deemed unworthy of how we used our powers. We fought him and beat him by technicality and gave us back our watches and offered us a chance to join his rebellion team to rescue Power Spheras. I declined his offer because his methods were wrong but eventually, lots of stuff happened and that's how me and my friends became a squad to search and rescue Power Spheras as well as saving the galaxy from harm."

Tanjiro blinked before asking. "What's a... Power Sphera? Is it some sort of entity or something?"

BoBoiBoy sighed. "Since you heard from me and Mr. Urokodaki, I'll explain it to you. Power Spheras are high-tech robots carrying powers unimaginable. They are countless of Power Spheras spread throughout the whole galaxy. Tanjiro, believe it or not, these robots are our protectors."

"S-Seriously?" Tanjiro is in shock. "I-I'm not fond of the technology you said but... to think something like a little sphere are our protectors around the whole universe? Even a galaxy?"

"Yeah." He replied casually. "As you can see here, I got my powers from a Power Sphera named Ochobot." He lifted his arm and showed Tanjiro his power watch from his wrist.

"That's... an odd device. What does it do?" Tanjiro asked and he became intrigued. BoBoiBoy quickly showed him the functions of the watch to him and explained it to him while keeping it in simple terms for Tanjiro to understand. Technology is still a new concept to a country boy like him.

"I feel like my head is gonna split." He felt his head getting light-headed from his story. It was a lot to process just from hearing it all in one go.

"In conclusion, my story entirely connects to what you've heard from me and Mr. Urokodaki when I explained my situation to him." He breathed in and out. It's probably the longest he has ever talked before.

"Thanks for listening, Tanjiro." He shot Tanjiro a pleasant grin.

"You're welcome." Tanjiro mirrored. "It's nice to know more about you. I wish my family was here to get to know you too."

"I'd like to get to know them as well, Tanjiro. From the way you said about your siblings, they seem like fun people. Your mom must have been a really kind person like you. I do wish I would've meet them in person before all of this happened."

"You tell me. If I had known about demons back then, then none of this would've probably happened." Tanjiro clenched his hands into fists.

BoBoiBoy instantly calmed him down. "Tanjiro, even if you knew, the outcome would still be the same. I mean, everything happens for a reason."

Tanjiro stayed silent, not knowing what to respond from that. Heaving a sigh, he looked behind them and saw Nezuko sleeping soundly. It was a while after she heard of BoBoiBoy's explanation of Power Spheras until her eyes became heavy and sinks into her slumber.

The other boy turns to look at Nezuko, sleeping peacefully. "Look at her. She's sleeping again."

"Nezuko. I promise I'll turn you back into human no matter what. I will never leave you alone. Even if it takes months, years, or decades to find a cure for you, I'll be doing it all for you." Tanjiro vowed.

"We'll do whatever we can to ensure Nezuko returns into a human again, Tanjiro. Because someday, we'll be grown-ups. And after that, we'll be old people and eventually die. And the demon Nezuko would end up all alone." BoBoiBoy said.

"Yeah. You're right." Tanjiro said. "It'll be sad for Nezuko to be all alone. I will not let that happen. I will not."

"Hear that Nezuko?"

BoBoiBoy placed his hand on Nezuko's head and rubs it gently.

"Your big brothers will be here for you."


Hi! I'm back with another chapter. It's my first to make a real dialogue-heavy chapter so I apologize if there is some parts that are way off. I did the best as I could to make it seem entertaining as possible.

And as always, thanks for reading and I'll see you all in the next.
