Kei's Pov

Its been a few months and im finally getting ready to reunite with inosuke zenitsu tanjiro and nezuko we have been assigned a mission with rengoku-san a very lively and bubbly personality

My sword has been shipped in even with sanemi trying to stop him haganezuka managed to attack me for breaking my sword

I watched as my sword went from the average sword to a lilac color it gave me chills just to see it change once again

I pack the little amount of stuff i carry along with the torn haori before looking for sanemi

He was outside talking to what seemed to be shinobu i guess she had come to bring me to the butterfly mansion I walk out to get ready to leave

"Hey creep dont let me see you come back here"he said crossing his arms i nod smiling

"You wont i'll make sure of it shinazugawa"i said crossing my arms acting like him

he pats me on the shoulder "i mean it to i already deal with one tomioka i dont need two"he grunted i nodded

"Aye aye captain"i said before walking away with shinobu

"Ara i see that you made the brute like you"she said i shrugged

"Yeah hes a douche bag but once i stayed long enough he eventually warmed up to me"i said smiling she looks at me funny "what is it?"

"Oh nothing its just im surprised a demon as yourself didnt attack he is marechi afterall"she said i sighed thinking about those times that his blood almost got to me

"Well im not falling for that trap a vowed that i wouldnt lay a nail on a human after aniki became a hashira"i said she doesnt know she couldn't

"So after you attacked the loner tomioka-san or before"she asked in a more threatening manner it sent shivers down my spine

"A-afterwards how did you--"

"Oh we all know sanemi did to"she said i went quiet thinking

"I've changed i promise shinobu-san i feel terr-"

"No not everyone agreed with oyakata-sama but he knew you pnly had intentions to help"she said smiling she seemed angry she doesnt like me

I bet no one does but that doesnt matter "did you tell tanjiro and them"i asked she shook her head

"No but they will find out sooner or later"she says

After an hour or two walking she actually seems nice but theres an underlying taste of hatred i mean i couldnt blame her im a demon my kind has killed a multitude we get to the Butterfly mansion

I spot the boar head of inosuke and the whiny zenitsu ahead of us i also say giyuu talking to tanjiro

"Look monitsu gonpachiro its kai" inosuke i let out a chuckle

"My name is the easiest to remember yet you still pronounce it wrong"i says chuckling we head to the train station to meet with rengoku-san

Once we got there inosuke of course not seeing a train tried to attack it and the police where alerted then we had to jumped on because we had to run off

We heard someone loudly yelling delicious we walked up to him to find out that he is the one we have been looking for

"Hello rengoku-san?"i say sitting across from him
