Tanjiro heaves a breath before he took a breath back as he do the total concentration breathing

'I'd try to pull it off through day, night and during bedtime... But I can't do it at all! ' He thought before he falls to the ground

He shakily brought his hand to the engawa as he slowly got up
'I concentrate my breath all the time and it's messing me up! I can't take it, my lungs and ears are hurting. I can feel thumping in my ears,my eardrums!'

He bought his hands to both of his ears as he checked on his hand
'I'm scared! I thought my heart is going to pop out of my ears!' He cried out

The three girls peeked on him as Tanjiro calmed down
'Must breathe with my lungs, if I can't do that it means my lungs is weak. I must do my best! '

"Here I go! " he shouted

"Tanjiro-san is working hard every day"
"Mhm, let's make him some rice balls! "
"Good Idea! Not to mention.. "

ೋ❀❀ೋ══ ❀ ══ೋ❀❀ೋ

"Blow a gourd? "

"Yes, when Shinobu-sama trained Kanao-san, she always made her blow these. "

"That sounds like fun.. " Tanjiro spoke as he took a bite of his rice ball

"Do these gourd make sound? "

"No, you must blow it until it breaks"

'Until it breaks? ' Tanjiro deadpanned

"This thing?! This rock solid thing?!"

"Yes, this gourd is special. It's harder than most gourds. The hashiras along with Kanao-san and Hayami-san are able to break it! "

'Even a petite girl like her fan break a gourd just by blowing it?'
Tanjiro thought to Kanao

'I can understand Hayami-san because shes a demon so of course she has a extraordinary strength but her?! '

"The size of the gourd slowly changed too. But Kanao-san managed to blow it until it broke. This is the gourd. " they showed him the big gourd

"As for Hayami-san case she accidentally managed to broke it because just like you, she thought it'll make a sound so she blew it too hard that it'll broke"

'Accidentally? It's so big too! I'll do my best! '

ೋ❀❀ೋ══ ❀ ══ೋ❀❀ೋ

The next day

"They took a break again? "

"I'm sorry, I'll take them tomorrow"

"Never mind, you can let them be"

"I'll do my best.... "

After rehabilitation, Tanjiro trained at the sunny outside as he swing the wooden sword as Shinobu watch he train not too far away

Fifteen days later
(Idk I just skip I'm too lazy to write it. Sorry)

Tanjiro sat on top of the building as he meditate, he breathed in and out

'Take a deep breath, let the oxygen flow into my fingertips.. '

Suddenly he was having a imagination of how Haganezuka would react when he break his sword. Making him unconcetrate as he tried to regain his concentrate. Not noticing someone was behind him

"Hello? "

"Hello? "

"Helloo? "

"What?"

"You've been working hard. " Shinobu whispers besides him making Tanjiro flustered as he turn to face her

"I wonder where your friends are now. "

'So close!'

"Don't you feel lonely? "

"Not at all! If I can pull this off I can teach them how to do it. "

"You have a sincere heart."

Tanjiro stammers for a bit. Then he turned to look at the dark night sky

"Why did you bring us here? "

"You were critically injured. Besides, Id like to pass my dream to you"

"Dream? "

"Mhm, a dream for humans and demons to coexist in peace. I believe you can make it happen"

They both turned quiet as Tanjiro smelled something. He turned to face Shinobu as she stare back at him too

"Are you angry? "He ask as her eyes widened. " I always get that angry scent from you.even when you are smiling" Shinobu then look ahead

"You're right. I'm always angry. Ever since I lost my sister to a demon, every time I see someone cried as demons killed their beloved one, and every time I hear cries of despair, the anger keeps building up inside little by little. "

"My sister, is a gentle person like you, she was sympathetic to demons, she even felt bad at the brink of her death. I never even felt that way. Why you should pity anyone who kills people? It's stupid.
But.. Since that was my sister wishes...I have to move on with my life. I hope there is a way out of this without killing the demons, I have to preserve my sister's smile"

"But I'm tired.. Demons are full of deception, they're selfish. They kill people without even think twice" Shinobu stands up. "Tanjiro-kun, please do your best for me. Do your best to protect Nezuko"

"... "

"You stopped your total concentration breathing. "

"Oh! "

She smiles before disappear to went to another place

ೋ❀❀ೋ═══ ❀ ═══ೋ❀❀ೋ

After a while Tanjiro get off from the building as he was trying to find another place to do his total concentration breathing. Until he met someone again

"Hayami-san? "

"Tanjiro? What are you doing here?"

"I think I'm supposed to ask that... Aren't you supposed to stay in the wind hashira's mansion? "

"Oh hehehe, I sneak out... "

"What?!"

"Chillax, I've been doing this for a while now, he's treating me like a 5 year old telling me what to do bla bla bla.. " Hayami mimicked

"... "

"Anyway, I heard you were having a problem with keeping total concentration breathing right? " Hayami ask as he nod "then you've come to a right person then! I can teach you how to keep doing your total concentration breathing"

"Really?! How? "

"Easy. Watch me" Hayami grinned as she engulfed her blood demon art on her hand "since you're not gonna die getting in the sun, I'm just gonna burn you if you stop breathing. "

"What?! But Hayami-san, can't you do it in a better way? "

"But that's how the wind hashira taught me to do the total concentration breathing. Well, sort off"

*flashback

Hayami's POV:

"Let me go dumbass let go! " I yelled as I wiggled my legs, trying to free myself from the tree that Sanemi tied me up to

"If you can't do total concentration breathing till before sunrise, I'm just gonna let you burn in the sun. " Sanemi threatened me menacingly before he left

'Oh shit! I don't even get to eat my last ohagi yet! I'm gonna be dead for sure! ' I thought as my eyes watered

*end of flashback

"And turns out I'm not dead yet and I get to eat my last ohagi! " Hayami laugh as Tanjiro sweatdrop

"Although it's just a tips, I'm not gonna force you to do it, I hope you can do total concentration breathing without stopping, see ya. "
Hayami wave before went to another place

HAYAMI'S POV:

After my chat with Tanjiro, I head back to the wind hashira to get some sleep cause I'm tired as hell with all these sneak out

After I got in quietly but successfully, I went to my room and took off my haori, put it aside my futon and doze off

'Mannn... I'm tired... '

ೋ❀❀ೋ═══ ❀ ═══ೋ❀❀ೋ

On a sunny day, Zenitsu stirred from his sleep and woke up.
'Tanjiro already went to training... '
He thought, seeing the empty bed

He heard the door slides open so he turn his head to the door, seeing Hayami walk in with Chuntaro in her hands

"Chuntaro?..."

"Chu! Chu! "

"Why is Chuntaro with you? "

"It crashed in front of me, so I asked it where it want to go to, it told me here. "

"Chu! Chu! "

"Are you worried because I'm falling behind Tanjiro? Even if he teaches me slowly, I still can't remember it. "

"Seriously, I don't think Tanjiro will care if you're a slow learner, you're lucky you have a kind friend. I got yelled 'idiot' because I'm slow... " Hayami spoke with a tear at her eyes, remembering her training before

"Chu! Chu! "

"Work harder?... "

"Chuntaro's right, you should work harder, I thought you said 'I WiLl pRoTEcT NeZUkO AlL ThE TimE' " Hayami mimicked as she do a kissy face while twirling around

"Stop that. I never said that.. But, you're both right though.. " Zenitsu say as he took the medicine and and gulped it quickly while Hayami went to Inosuke's bed and poke him. After Zenitsu drank his medicine, he looked beside him Inosuke standing on the bed

*puff "let's go Monitsu, Koyami. "

ೋ❀❀ೋ═══ ❀ ═══ೋ❀❀ೋ

"What Tanjiro plans to learn is technique called constant total concentration breathing. By using it for the entire day, your basic physical activities will increase drastically. " Shinobu explains as both Inosuke and Zenitsu confused

"Let's give it a try now. "

*BANG

They both panted as Zenitsu wiggled

"No way! It's impossible! "

"Yes way, you guys are just too weak. " Hayami deadpanned

"If I don't push myself harder, I also can't do it. You two will be fine. Expand your lungs like this, when your blood flow is disrupted, your bones and muscles will clack like boom boom! And maintain it at that moment. "

"... "

"After that, tons of training! " Hayami said as she spread her arms

Inosuke and Zenitsu deadpanned as they shakes their head virgolously

Shinobu suddenly appeared out of nowhere as she appeared behind Tanjiro

"This is the first basic technique, you still need to put in a lot of effort to master it. "

She then moves toward Inosuke and pat his shoulder

"Can you do it? If you can't learn it, then it's fine.Such a shame..."

This irked him up

"WHAT?!? I'LL MASTER IT! DON'T YOU DARE LOOK DOWN ON ME! I'LL RIP YOUR TITS OFF! "

"Not the tits.. " Hayami muttered. Then she notice Shinobu walk to Zenitsu and held his hands, making him blush

"Please do your best Zenitsu! I'll cheer for you! "

"OK! "

'That was something... '

ೋ❀❀ೋ═══ ❀ ═══ೋ❀❀ೋ

Day after day, the trio seems to impseem, Tanjiro also manage to succeed all of his rehabilitation training with Kanao. Same as his friends too. That night, Matsuemon
landed at the engawa where Tanjiro
and his friends we're resting

"It's morning, wake up! Caw! "

"What's wrong? "

"Casualties on the Infinite Train has increased. More than 40 people are missing. The flame hashira will guide you and someone will come with you at your destination. Head west at once! "

The wind hashira estate

HAYAMI'S POV:

I was peacefully sleeping in my room when suddenly, something gawked at me. I rubbed my eyes as I look at the window

"Sora?... What are you doing here?... "

"Caw! You have a mission! Head west head west! More than 40 people are missing on a train! "

" A solo mission?.. I never went to a mission without Sanemi before..."

"The flame hashira will be with you along with some slayers! Go now! Get up! "

"Alright jeez... "

Before the sun got up, I got ready to go to the mission since it was quite far, I wore a amigasa on my head so that I won't get burn when the sun is up. I also wore a fingerless black gloves on my hands just in case.

"Where are you going? "

I turned around to see Sanemi. Still in his sleepwear with towel clung on his shoulder

"I don't know, kind of like sounds crazy but.. Sora called me on a mission. He said the flame pillar and some slayers will come along.. "

His eyes seems to widen a bit
"You never been to a mission without me before. Why so sudden now? " I shrugged

His eyes traveled to other place. The he sigh. He then walk up to me and took something inside his yukata

"What are you doing?!? " he just tched and grab my hand. Then, he put a quite a big stack of money on my hand. My jaw dropped

"What the hell?!? Did you just took out some goddamn money on your goddess body?!? "

"Shut up and just take it! So that you won't ask for someone else money or food if you're hungry! It made me look like I'm broke... " he muttered on the last part

"Well damn, your wife gonna be so lucky when he married you. Anyway see ya. "
I was about to slide the door when he suddenly called me. His back is facing me

"Take care.. Don't die.. "

I went quiet for a second. He never say that to me before. Then I replied

"Okay! See you! "

𖣘Sanemi actually care about Hayami after years knowing her. She feels like a family to him. An annoying one sometimes.

𖣘The amount of money Sanemi gave Hayami is one million yen!
(That's around $6000+USD!). He doesn't usually use much money but since Hayami moved in, yeah, it raised up a bit..

𖣘Hayami start to call him Sanemi like a week after they met. It irked him at first but then he got used to it
