Breathless - A Kimetsu No Yaiba Story

Spars and breath of love

I accepted to take (Y/n) as my disciple without much thinking because I related to him, but now I'm starting to regret.

Sure, we both have a weak constitution but I can still use breathing style and even without cutting a demon's head off, I can still kill it with poison, but that boy will be out of breath after killing just one demon.

I don't think I can be of any help to him...

The meeting came to an end and I went back to the butterfly estate.

"Kocho-sama !"

"The new guy is mean !"

"You have to kick him out !"

The three little girls that work here, Naho, Kiyu and Sumi, came crying to me.

I swear if he hurted them...

"What did he d- *pfft* "

I couldn't hold my laughter when I saw the three girl with their names written on their foreheads.

"He said he couldn't remember our names !"

"So he did that to us !"

"Kocho-sama are you laughing ?"

"N-no. I'll scold him, don't worry."

The girls guided me to where he was : the garden, where a peculiar sight was waiting for me :

(Y/n) was here pen in hand, writing "Kanao" on Kanao's forehead, which looked surprised and confused.

-A few minutes sooner-

I was visiting the butterfly estate after writing the three girls names on their face. I have a poor memory for names.

The butterfly estate was a big, traditional house with a large garden, it was really beautiful.

When I reached the garden after visiting outside, I saw a girl with pink eyes and long black hair, tied to the side of her head by a butterfly hairpin in a demon slayer uniform.

She was looking at butterflies.

"Hello~ My name's (Y/n), I'm new here ! Nice to meetcha !"

She looked at me, then took a coin and flipped it. It seems luck was on my side as she answered.

"Hello. My name is Kanao Tsuyuri. Nice to meet you." She said in a formal tone

"..."

"..."

"How do you write it ?" I said, taking the pen I stole, out of my pocket.

-back to present-

As I finished to write on Kanao's forehead, I heard laughter behind me.

I turned around to see my new sensei, trying really hard not to laugh but failing.

"Shibonu ! You came back."

"It's Shinobu, stupid." Said Naho, which I identified thanks to the writing on her face.

"And you must call her Kocho-sama !" Said Sumi

"Idiot !" Added Kiyo

"... How do you write it ?"

"Don't you dare." Said Shinobu suddenly becoming serious.

I value my life. I back down. I'll get her when she's asleep.

-the next day-

I began my training with a Shinobu which had "Shinobu" written on her forehead.
