Demon Slayer Fan Fiction ( Mreader )

Chapter 4

A/n: Well the way I left the last part was quite unfair Ill be honest. Tho it would cause some suspense. So where we left of. We found that Rui was actually the lower five of the kizuki and not some fushover demon. So lets get back to the story.

Rui: Im going to kill you now. *starts another move enhaced by his blood demon art* Murderous eye basket.

Tanjiro: *closes his eyes anticipating death*

???: Its not your time yet kiddo.

A/n: Rui's technique hits this mysterious person that protected Tanjiro.

Tanjiro: *openes his eyes and they widen* Y/N!!

Y/n: *has a big smile on his face* Time to kill this bastard woudlnt you agree Tanjiro?

Tanjiro: Hai

Y/n Well lets put on a show then. *dashes at Rui*

Rui: ( shit shit shit. What's a hashira doing here and who the fuck is he I've not heard of this guy before ) *connects his hands together creating a red circle of concentrated threads and releases it* Cutting thread rotation. *laughs* this is my most powerful attack you wont be able to defeat me when I use this.

Y/n: you sure sound confident with yourself. *smirks and grabs onto his sword and gets into one of his iconic stances* Star breathing. First form. Pericing Star. *becomes a spear of light that now follows by the moonlight itself*

A/n: this has happened as a result of his partial training with that form.

Rui: *cut forms on his cheek and he looks to his left to see his attacker* what just happened. How is he so fast. *see a person dressed in black and purple and long red hair that resembles one of the twelve kizuki and becomes absolutly terrified* thats impossible why are you here. *Jumps back and sends everything he can think of at Y/n* Why are you here Kokoshibu?!?!

Y/n: ( what is this person talking about. Now that he mentions it people seem to be surprised when they hear my last name is Tsukiguni. Could the person hes talking about be related to him? ) who is this Kokoshibu you talk about?

Rui: *calms down a little* HE'S THE UPPER MOON ONE AND YOU LOOK ALMOST A LIKE!!!

Y/n: thats why people are worried by my last name. Why did I have to have a ancestor that was a demon. *gets into a fimilar stance that Kokoshibu would get into* Moon Breathing.

Rui: *drops to the ground as he cant compete with moon breathing* its over I cant beat that.

Y/n: Third form Loathsome moon chains...

A/n this would destroy most of Rui's body and left him unable to regenerate.

Y/n: *walks up to Rui* at least die with honor demon. ( tho I get a feeling that his life was more sad then what ive seen from his actions ) well orders are orders. *looks at Tanjiro* you ok there kid?

Tanjiro: only some injuries that will heal nothing too serious.

Y/n: *sheaths his katana* well I would like to have a word with you after youve healed. You used a different breathing style and im interested to what it is. I could sence your water breathing but it changed to something violent. So when you heal up you better start talking.

A/n: the demon slayer medical core team lead by Shinobu finds themself on the mountain attending to all of the injured.

Y/n: *sighs* that was more disappointing then I thought it was. *thinks of what happened before the fighting and shakes his head* why did that have to happen on the way to battle. ( tho I could tell that she was nervous her hands were shaking but she tried to hide it )
