The Demon Lord Returns || Demon slayer AU

Who Are You?

FIRST PERSON POV

'(Y/n).'

'(Y/N)!' S.D now screamed.

I quickly snapped out of my trance, restless from the hour less nights I spent alone. The coffee I was pouring was overflowing my small mug.

"S-Sorry I was just worried about... Somethings." I quietly muttered, kind of like I was going to be punished by the tall handsome man.

"Dont apologize. Are you okay? Are you burned?" He said inspecting the hand that apparently got touched by the hot drink from my reckless behavior. I didn't notice.

"Of course I am." I said, pulling away my hand. I wasn't a baby, and I might as well be one of the strongest beings alive, of course though, next to S.D.

"I- I understand. Are you ready to go on the mission." He firmly asked, stuttering from the woman's sudden movements.

"Yes." I now replied, annoyed. It was his fault i'm here. Right now I should be next to Gojo and Itadori and even Megumi.... I can only be hopeful that Gojo would be okay by himself.

"Even if you're upset (Y/n) I have something I need you to complete this mission. It will be one of the most important ones youve had in a while. You're strong, mentally and physically. You can push through any situation with a smile. That's why I love you and that's why you're in the #1 spot. Will you help me even though you may not be fully mentally prepared right now? We can wait but I don't think you'd like to." S.D. professionally asked me, staring directly into my eyes without blinking once.

"... You know I don't want to but you ask anyway? Cant Drevous do it??? He's strong." I asked, now even more annoyed and irritated that he asked me that of all things right now.

"He's on his trip to One Piece.... He uhm. Let's just say.... He wont be back for a while." S.D. said, thinking of the reply to give.

"Isnt One Piece like... 1000 episodes long....." I replied, this time astonished, forgetting the previous anger I had felt.

"Yeah I would've sent you but I can't be away from you for more then a few months." He cutely said with a brightening smile, walking towards me and booping my nose.

I blushed.

"Sigh.... When's the mission." I asked after hearing the mans reasonable excuse, giving a big breath in and out.

"Are you going to ask where you're going?" He said, watching me walk off with my coffee mug in hand and phone in the other.

"I don't care." I replied, truthfully.

"I think you might, Demon Slayer universe, does that ring a bell?" He stated, a wide grin showing on his face, knowing this would cheer the woman up from her depression like state.

"Di- Did you just say Demon? Slayer?" I asked, mouth wide open as I slowly turned towards the man.

"I did." He replied.

I sat there in shock. How long had it been? 500 years 1,000? No more... Probably around 10,000 years at this point. The memory of the beautiful land flashed through my mind. I couldn't remember much of it but.... Him..... His face is so vivid in my mind, like the smell of gasoline or the color of a ripe apple. It's like he's right here now, the small child I had loved so long ago.... right next to me...
