A Few Days Later,

He arrived at the Demon Slayer Headquarters and goes inside it, as he go inside he hurriedly walked into the building of Shinobu and he saw the children playing and Kie,Shinobu was chatting with each other.

He called Shinobu " Hey Shinobu! got a minute? "

Kie,Shinobu and the children noticed him and they all shouted at the same time " Welcome back! Onii-chan/nii-san/Mark-san/Mark ! "

Mark smiled " Yeah, thanks "

Kie and Shinobu noticed something different from him, normally he wouldn't smile he will have his stoic like expression when he talk, but today he smiled! not just barely visible but a normal smile! which made them stunned Kie couldn't help but ask " Mark-san..did something good happen in your journey? "

Mark looked at Kie and said " Yep, indeed something good happened. "

Shinobu " Like what? "

Mark " Like courting a woman. "

Kie/Shinobu " HUHH?!/WHAT?! "

Mark got stunned in their reaction " Huh? what's with you guys..it's just courting a woman. Why would you guys have a problem with it? "

Kie and Shinobu shouted at the same time " Of course, THERE IS A PROBLEM!!! "

The childrens was startled from their shout and Kie said " Let's go somewhere private "

Mark nodded and he followed Kie and also Shinobu, as they walked they arrived at a certain room without people in it and there Kie sitted down and said " Okay, now please tell us about what happen within those few days of journey of yours! " Shinobu also nodded

Mark stared at Kie " Why would i tell you about it? it's none of your bussiness right? for me to court a woman? "

Kie and Shinobu bite their lips and shouted " Of course it does! it's because WE LOVE YOU!! "

Mark got stunned, he knew about the feeling of Kie since it was the reward from the Mission, but Shinobu's feeling he didn't expect " What? seriously? "

They both nodded while blushing, Mark pondered seriously and said " Well..i didn't expect you to fall in love with me Shinobu. "

Shinobu was avoiding, Mark's gaze she was embrassed and said shyly " W-what! is it wrong to fall in love?! "

Mark smiled " Nope, but you should have been more honest, okay here is the deal i can accept both of your feeling but please understand that you won't be the only womans that i would be in a relationship in the future. "

Kie/Shinobu " We are already aware of that! "

Mark got startled at their words " Eh? you do? how? "

Shinobu " Nothing really, i just felt it that you won't have a single woman as your wife, i felt that way. "

Kie " Same here. "

Mark got speechless from their replies but he didn't mind as long, as they accept the fact the he can't love a single woman and declared " Since it was that case, from today onward you are both my woman! no one can touch you as long as i am alive! "

Both of the woman was smiling sweetly, finally their feelings was accepted, the rival thing was just an excuse for each other, they just wanted to know if, she was worthy of Mark's love and so they both accepted each other.

Both of the woman said " Now tell us what happen! "

Mark sigh and end up telling them what happen in those days and the womans reacted " So? you have courted her because of a misunderstanding?! and end up courting her for real!? also you said she's a demon?! "

Mark " Yes,yea and Yep she is a demon got a problem? "

Both of the woman said at the same time " None! "

He looked at Shinobu " Can you, guide me where is your sisters grave? "

Shinobu got stunned of the unexpected words " Sure, but why? "

Mark " Nothing, it's a surprise for now " he smiled

Shinobu got speechless, she knows Mark's attitude and she sigh and said " Follow me "

Mark wanted her to be happy, since she was his lover now, he would revive her sister, actually he plans to revive Shinobu's sister later, but because of her confession it made him want to revive her now.

As he followed Shinobu, he was now in a certain graveyard and Shinobu stopped in a certain grave and she pointed at the grave and said " This, one... " she said sadly

Mark nodded and said " Help, me dig the corpse out. "

Shinobu angry shouted " Huh?! why! "

Mark " Don't you want to your sister? "

Shinobu got confused " I do? but what does digging her Corpse do?! are you crazy?! "

Mark " No, i am not so want to help me dig or not? actually i can do it myself "

Shinobu gritted her teeth and said " Fine...! but even you do anything bad with my sisters corpse..even..even.. if you are my lover i won't forgive you! "

Mark smiled " Sure, i won't do anything bad to her corpse, if anything it's good "

As he said that, he started digging the grave and also Shinobu reluctantly working to dig her sister's corpse.

Time passes, finally the corpse was now showing and Shinobu emotionally said with a tears in her eyes " Onee-chan... "

The corpse didn't rot, as if that this body just died yesterday, Mark moved closer and he a stone appeared in his hand.

Shinobu who saw that was shocked, but she knew that this guy has a strange powers so it wasn't as shocking as before like he had shown her his so called ' Quirk ' and she couldn't help but say " Is that also a Quirk? "

Mark answered " Well you could say that "

Mark can show his powers to his Lovers, but absulotely can't expose the existance of Daine and Mark puts the stone in Kanae's corpse, since it was how you do it, after that a bright light appeared in the stone and the stone was slowly going inside in Kanae's c.h.e.s.t.

The stone got brighter and brighter and the corpse was also brighting, Shinobu shouted " W-what did you do?! "

Mark grinned " Nothing much! you'll know after! "

The bright was slowly disappearing in Kanae's corpse and after that the corpse eyes slowly opened(A/N : Just imagine that it's creepy lol like a zombie) the body stands up and looked curiousity at the surrounding and Kanae noticed 2 people was staring at her and she knew the other one and said " Shinobu? "

Shinobu can't believe of what she saw, it was her big sister! talking to her right now! as tears slowing falling in her eyes she said " O-onee-san? "

End -
