My one and only friend in this world

Yukiya and Shizue look for Tanjiro It took them a while but they did find Tanjiro and Nezuko looking very tired.

"What happened, " Yukiya asked and Tanjiro quickly says.

"Well I and Nezuko were fighting with the demon and we killed it"

But before too long Yukiya cow flies into view and starts to speak in a very angry tone.

"Yukiya, you do realize that I need to report about well you know the whole you teaching someone that is not part of the demon slayer corps!"

Yukiya then looks at the cow with an annoyed expression and then says. "Okay I know that but do you realize that me and Tanjiro are probably going need some help if we encounter a really strong demon and it is not against the rules to-"

But before he can finish his sentence Tanjiro cow comes into view and start talking.

"Tanjiro you have a new mission"

Tanjiro then looks at the cow with a confused expression and then speaks "Don't you mean Tanjiro and Yukiya you have a mission"

Yukiya cow then speaks up "You and Yukiya have different missions "

Tanjiro then speaks up."Well look like this is goodbye at least for now"

Yukiya nod at Tanjiro and Tanjiro leaves.

"So where is the mission"

Yukiya asked and the cow says "It's about a 2-day trip from here the demon there is really inconsistent so you probably have to look for a while"

And so they leave...

At some point in the trip, Yukiya and Shizue stop at an old house and Yukiya starts to speak.

"Okay first I will teach you how to hold a sword"

Yukiya then holds a sword and gives a stick to Shizue. "just like this"

Shizue then holds the stick like how Yukiya is holding the sword but she seems somewhat nervous.

"Like this right?" In a nervous tone and Yukiya nods then says.

"You doing quite well"

Then Shizue asks "I know that you are basically my teacher but can I think of you more as a friend?"

Yukiya then says "Of course" With that Shizue becomes less nervous.

After a while, Yukiya was confident that Shizue was ready for the breathing techniques and so began to teach her the basics, and Shizue quickly mastered nearly all the basics.

Yukiya was really happy and surprised with how much progress Shizue had made in just one week.

And as for Shizue's progress with Snow's breathing, he can tell that she is on the verge of being ade to do the first form.

As far as the demon, they didn't encounter the demon well until…

Yukiya and Shizue were walking at night when Shizue heard something "Un was that a-"

Before she can finish her sentence a demon pops up out of a tree

The demon has a red bow coming out of his left eye.

Yukiya really his sword and gets in front of Shizue and the demon begins to speak

"So you two think you can kill me I don't think you can at least not without your deaths"

The demon then takes out the red bow from his eye and then says.

"Blood Demon Art: Red Arrows!"

He fires 5 red arrows at Yukiya.

"Snow Breathing: 5th form chaotic ice wall!"

Yukiya quickly sliced up all 5 arrows and the demon look impressed about it.

"Well that was rather impressive but now I think it's time to take things seriously" And then he says.

"Blood Demon Art: Near Endless Arrow Fire!"

He fired what seemed like infinite arrows at Yukiya.

"Snow Breathing: 5th form chaotic ice wall!"

Yukiya sliced up the majority of the arrows but one arrow hit him in the right knee and another arrow knock the sword out of Yukiya's hands and the sword landed near Shizue.

The demon starts to laugh as Shizue picks the sword "So you think you can kill me it looks like to me that you ain't even a demon slayer and we both see what happens to any demon slayer who tries to kill me!"The demon says.

Shizue then starts to speak in a somewhat scared but also determined tone.

"I know I am not officially a demon slayer and scared as hell but that's don't mean I let you kill my one and only friend in this world!"

That anger the demon as he then says.

"Blood Demon Art: Arrow of Suffering!"

He fired a large arrow at Shizue as she take a large breath and says,

"Snow Breathing: 1st form Sudden Chill!"

She slices the large arrow in half with a large and powerful slash.

"How dare you! That arrow was just gonna give you a slow and painful death that's all!"

The demon didn't see to note the fact she got closer to him "Now I mad and I mean real mad t think going to-"

Before he can finish his sentence Shizue slashes his head off and then quickly goes back to check on Yukiya.

"Don't worry I think can walk on my own"

Despite his saying that it was clear that Shizue was worried about him so he let her help him get up and walk through it did make him blush a little.

I am so sorry that I was extremely late.
