Kimetsu No Yaiba- Sun & Moon Fanfic

Chapter 3: Road of Hatred and Vengeance

A nice sunny day and a happy tone can be seen surrounding Tsukiyomi's home. Tsukiyomi can be seen running to the house, with a happy face. He was carrying a book and a sword.

"Mom, Dad, Sis; look what I found!"

He ran in to see his mom and dad were dead staring at him and he felt something hugging him from behind. He tilted his head to see half of his sister looking at him; then his sister started to speak.

"You broke our promise, onii-chan"

"Wait no it wasn't like that!"

Then two more voices rang out.

"You're ungrateful son"

"You left us to our death~ you could have warn us"

Then all three voices rang out all at once.

"""Tsukiyomi, why did you leave us just to DIE?"""

"I didn't I tried to help"

"""All that help and we still died"""

"""Failure"""

"""Why should you live?"""

"""Join us and we will forgive you"""

"No please stop, I tried please forgive me"

Tears came down his face; he wanted to escape, wanted to run, and wanted to kill the person who ruined his family and their future. He looked around his family who kept calling him a failure and left them.

["I vow to get revenge so you won't have to suffer in the after life" ]

His eyes started to glow and everything turned black; I opened my eyes to see a destroyed house and two objects laid neatly in front of me. One a book and the other a sword and a scabbard that belong to swords man from before. I felt a tinge of pain on my neck and my arms.

"Ow, why does it hurt so much? All I used was a butcher knife?"

I look around again and then look over to the book. I picked it up and a paper slid out; with writing on it.

I have given you a technique called moon breathing; I give this to you to make you strong enough to kill me. I hope you take this seriously or I'll kill anyone that causes you a hindrance friend or foe.

-Your Demon

I looked at the paper for five seconds; then I folded it and placed it in the back of the book. You don't have to worry about me not taking it seriously, I'm going to kill you! After being pissed off for a while I went to bury my family and the one warrior.

"I will avenge you all"

Then I looked into the book and skimmed it; I noticed there were 10 forms in moon breathing and it also has a training regiment. It also tells me to find a mountain that is very high and spacious to see the moon. Lucky for me I know a place that fulfils that and that is Mt. hankabe, which is nearby and it's about 5 hours by walking to get there. I got a leather bag and some food, pictures of my family, a sword, and money.

I walked and I walked and I made it in 5 hours; I started climbing up the mountain and I went up here once with my family, but this was a lot harder then I remember it being. The more I climb the less I can breathe in. I almost passed out just trying to climb up the dame mountain; also I wish I could read more books about plants and animals. After a while I was able to make it up and made it to the clearing where there was a small cabin.

I walked in and put my stuff down, took out the book and looked at what I should do. After a year of stamina training and basic sword training. My training consists of me hunting animals at night with traps and setting them up in day time; I did a lot of sword swings and Standard workout routines; also I washed myself in the river that's nearby the cabin. I felt confident to learn breathing and so that's what I did, but for some reason I keep feeling weird. It's like trying to open up my body every time I take a deep breath. It hurts my lungs and to the point that I passed out. I re-read the book to find any hints to help then what I already gave, but none showed up. So I decided to stop breathing and do some meditation under the moon. Funny part is that I meditated for 3 months straight and my body felt a tingly sensation. So I try again with the breathing, but this time I try to follow the flow of what the moon showed me.

"*Breathes in* So this is the feelling of the moon"

I stated and started to run, but I wasn't use to this new found speed and- *BAM* I hit a tree.

"OWWW that hurt!"

I yelled, but I was happy I was able to do it. Then I tried my eye thing again and it was even bigger then I last saw it. It goes up to 10 meters now, before it was 5 meters. Anyway, I wonder if I can keep this going forever? And that's what I did for nine months and I was able to do it when sleeping or doing anything. It was really hard, but I was able to destroy trees by making holes in it and blowing through it. It took time to destroy it from the inside out, but it also boosted it's range up to 25 meters.

Now I can finally start learning the Moon breathing techniques.

"First Form: Dark Moon - Evening Palace huh? I might as well try and see if I can recreate that moon thing"

One year later, I was able to "master" them, but the problem is that I can't perform that moon crescent that he made. I feel like I'm missing something; maybe I should ask the moon? I started to feel the flow of the moon and I followed it to my scabbard.

["Is it telling me to use the scabbard alongside my sword? Maybe the sword can bring the direction of the move while the scabbard can bring the power? Divide and conquer that's the answer!" ]

Six months passed by getting used to my new fighting style and I was able to master the first form. I was able to recreate what he did with that slash; three months passed by and I was able to truly master all of it. The hardest one was the Fourth Form- Rotating Moon, because it allows one to go in a straight line while rotating. (A/N: It's like kung fu, they have a spin when they move forward or like a beyblade angled to make it go straight while spinning. I hope that clarifies the move!) The thing is adding my scabbard to the mix just adds more destruction then it needs. So I think I won't use it that way unless I'm up against a crowd and need to be fast. After mastering all of it, I notice how much ruin I cause on the mountain.

"I should start heading out huh~"

Then I noticed five things nearby, I got my sword and scabbard ready to fight with.

"Who are you five?"

I asked and five of them surrounded me and I noticed one of them had a number on one of them. All of them were guys and they looked hungry.

"Lower 3?"

"Ah~ is the cute yummy boy scared now?"

"Look at that nii-chan, his smell is so goooooooood~"

"Shut it Revis, you're disgusting"

"Crownose is right you know Revis~"

"HAHAHAHAHAHAHAHA!"

"Can you guys shut up!"

They ignored what I said, but looking at them they have long hair and they look the same. The only difference is their eyes and that's it. They give off tons of pressure, but not like the upper one demon.

"Do you guys know who the Upper one is?"

I asked and silence and the lower 3 looked at me with a confused expression.

"Why would I tell you that?"

"Then you don't have a use being alive 'Moon Breathing;[Fifth Form: Moon Spirit Calamitous Eddy]"

Bright moons and slashes started to form a rising vortex. All of the demon's heads were cut off. Then 4 of the demons were reabsorbed into lower 3.

"How? You didn't draw your sword!"

"Oh, but I did~ now tell me about the upper one!"

"I have no information about the upper one. The uppers is much more different then lower-"

Then he disappeared and I looked up at the sky; so I need to find an upper to get my info. It's time to leave the mountain
