(Y/n)'s pov:

"Caw! Caw! Mission! Mission with the kamaboko and the insect hashira!"
(C/n) said "w-what's the mission
(c/n)?" I asked

"Maid has been missing at a mansion! You have to disguise as a maid! Caw! Caw!" (C/n) said

"Eehh!!!! A maid outfit!!" I said in surprise "c-can I back down" I said
"No can do!" (C/n) then left

I got to my room and get dressed

I then got some for the kamaboko and walked down stairs, when I arrived Tanjiro choked at his food when he sees me "(Y/n)-san! What are you wearing!?" He then got up and started shaking my shoulder

"I-it's f-for t-the m-mission t-tanjiro-kun" I said nervously, he then let go "d-don't w-worry t-though y-you are g-gonna b-be t-there t-too" he then stared at me.

But I grabbed his hand and dragged him to the bathroom then pushed him inside with the dress and closed the door "wear it or I'm going to increase your training" I threatened after awhile the door then opened and revealed a red faced Tanjiro in a maid's dress

I then again dragged him to the living room, when Zenitsu saw Tanjiro he laughed, while the girls giggled.

I then dragged Zenitsu and pushed him into the bathroom with the dress and threatened him just like Tanjiro, he then came out of the bathroom with the maid dress on

"(Y/n)-chan" he said with a red face and then next is Inosuke without his boar head

"Now to Shinobo's state!" I said and dragged the three boys then waved at the giggling girls.

(Time skip)

When I walked at the butterfly's state I bumped into Kanao "a-ah K-kanao-chan d-do y-you k-know where Shinobo-chan is?" She then flipped her coin "she's at her office" I then nodded "K-kanao-chan can I borrow your coin" she hesitated but hand me her coin.

"You use the coin to make decisions right?" She nodded "then let's use this coin to make decisions, when it landed on head's, you'll listen to your heart okay?" I then flipped the coin and it landed in head's "from now on your gonna make your own decisions Kanao-chan" I close my eyes and smiled then walked to Shinobo's office.

Kanao's pov:

I blushed and I hug the coin close at my chest 'don't worry (y/n)-sama, I'll try my best' I then smiled.

While watching (y/n)'s figure getting smaller and smaller.

(Y/n)'s pov:

I entered Shinobo's office and saw her doing some paperwork "Shinobo-chan~" she then looked at my direction "(y-y/n)-chan! W-what are you wearing!?" Shinobo said

"I-it's for a mission we're going" I explained "you have to wear one too"

She was about to run but I caught her "wahh!!! But I don't want to wear it!!!" She reasoned but I shake my head "you have to its for the mission"

After awhile of arguing, she finally give up and wear it

(Time skip)

"So where do we find this mansion?" Tanjiro asked "it's around this corner" Shinobo said

"Here we are" She said

she then knocked at the door "hello~ " 
The door then opened "yes, can I help you?" A girl said " we heard that you have high quality of payment for a maid here, can we apply?" Shinobo said

The girl then smiled "of course! Please come inside" she said "T-thank y-you!" I said in a fake smile followed by the kamaboko.

But when we got inside the mansion the girl then laughed "ahahaha! Your gonna be my meal today! You fullish humans! Hahahaha!" But then her laughing turned into a wide evil smile, when she sees our swords.

"It's my luck! I have a demon slayer in my mansion! He sure gonna give me some of his blood if I can kill you all!" She said and attacked while we bodge and got our swords.

I then launched at the demon and slashed her head but I missed and it cut the hand only.

She then launched some needles Shinobo in a fast pace but taked the hit for Shinobo "(y/n)-chan they shouted "I'm okay" I said but then got thrown in to another room by another demon's vines.

Tanjiro's pov:

We're fighting the two demons and
(y/n)-san got thrown in the other room and we're starting to get worried "oi! Monjiro go get (m/n)! We're gonna be alright!" Inosuke said "Go Tanjiro! Go get (y/n)-chan!" Shinobo and Zenitsu said.

So I ran to where (y/n)-san got thrown and I saw her about to get stand up but her feet is bleeding "(y/n)-san!" I shouted and she turned to look at me
"Don't try to stand your feet is bleeding" I said "here let me help you" I got some bandage and about to tend her feet but she grabbed my hand and shake her head "but (y/n)-san! It's bleeding badly!" I retorted but she only shook her head, when I was about to speak a bright light stopped me so I looked to where it came from and saw (y/n)-san's blood forming into something, she then hold it and said  "dark boots, activate" and it then came back at her feet

The blood then become a boots she then started to stand up so I helped her she then smiled "let's go back to the others" she said and I nodded, we then started running back.

(Time skip)

When we got back Zenitsu is about to get choked and with my speed I still can't make it, but then (y/n)-san saved him by kicking the demon's head hard that it came off of its neck and then turned into dust "(y/n)-chan your okay!" She smiled at Zenitsu and patted his head, I then felt a little jealous but I waved it off.

She then healed Zenitsu's wound and proceed to find the others.

When we got there they now have defeated the demon. They then turned around and Shinobo hugged (y/n)-san and again I felt jealous, just like last time I waved it off. But then (y/n)-san's  boots deactivated

"The mission is finish now it's go back home" Shinobo said and we nodded but then a door appears at the floor Shinobo-san's standing "Shinobo-chan!!!" Then there's a blur of blue passed at me and pushed Shinobo-san away and all we have to do is look at (y/n)-san in horror when some chains pulled her in the door "(y/n)-chan!!" Shinobo was about to hold her hand but didn't made it because the door is now closed and then disappeared, when it did I dropped to my knees while Zenitsu and Inosuke is silently crying.

'what I'm I gonna have to tell to nezuko that (y/n)-san is gone' I thought.

(At the headquarters)

Shinobo's pov:

"Welcome back!" They said and smiled but I couldn't even look at them and so is the kamaboko trio.

Their smile then turned into frown "what's wrong? And where's
(y/n)-chan?" Mitsuri asked "w-wait d-don't tell me she's-" she couldn't finish her sentence because I cut her off "(y/n)-chan's gone!" I shouted while crying, she then fool's to her knees and cryed while the others cried silently.

Taisho secret:
•when they tell Rem, Ram, Yin and Yang about what happened, they believed that (y/n) is not died yet and will return.
•(y/n) and nezuko know each other because they meet at the flower field at night and they make a flower crown together and also stargazing, while (y/n) is singing.
