Chapter 1

The Sato family's workshop

Kioshi! come to the back and help me for a second!

In the dead center of Wisteria city, there was a workshop modeled after a normal japanese looking countryside house, surrounded by beautiful pink wisteria flowers hanging over the house and the greenest of hiya leafs growing down the walls.

Deers, cats, dogs, squirrels, birds of all kinds were happily singing and enjoying themselves in and around the Sato family's workshop. It was a simple looking house, but all the animals gathered and the nature around and on the house made it look like it had been sent down from heaven itself.

I'll be there in a second!

A boy answered with a contempt and genuine smile on his face, standing at 195 cm tall, pretty lanky looking, long fluid black hair that reaches down to his shoulders, sharp facial features, as well as the darkest of black colored eyes, and wearing a blacked out kimono. It was the face of someone who was abnormally pleased and contempt with the life he had lived. Kioshi Sato was turning 17 this year, and as promised by his father, he was going to learn the art of smithing that had been passed down for generations in his family.

The reason Kioshi was so excited to learn this art was because when he was younger around the age of 10-11 he had secretly snuck out of his room were he slept with his parents, and in the middle of the night stumbled upon the smithy were all the weapons ever created by his family was located. Kiyoshi saw a short sword that he thought looked the coolest and yanked it off the wall. As he held the short sword he noticed the fine details on the handle, blade and hilt. Silk threads of white wrapped and spun in diamond like patterns around the handle, The hilt was modeled after the whitest cloud. And as he looked at the blade of the sword he noticed that the blade had no impurities in it, it was weird because he had absolutely no knowledge of smithing or swords or any weapons in general, but he knew just from one glance that this sword was the creation of a true smithy master.

"I Can't wait for father to teach me smithing, it's about time he did, i've been patiently waiting for a long time and I already know what kind of weapons I want to design and create".

As Kioshi made his way into the house he opened the door and walked to the back of the house were the cottage was located and moved the big chests of silk and metal out of the way. Entering the double door connecting the house to the underground smithy, Sato could hear the banging of metal against metal, the smell of burnt coal aligned with the feeling of the high temperature of the cooling process, sweat began to form on his forehead as he walked closer to the source.

Upon entering another door of pure metal with his own key, he saw his father working as hard as ever pounding the metal with a loud but gentle "clang!" seeing his father working hard Kiyoshi thought about making him some sandwiches.

'Yeah I'll make him some sandwiches first, I don't want to ruin his concentration'

"Kiyoshi, come over here, I wanna show you something"

"ahaha, so you heard me after all"

As I sat down right next to my father on his bench, he showed me what he had made for me.

"It's something i've put a lot of effort into so don't lose okey?"

"Of course I won't lose it Father, thank you, how did you know that I wanted this?"

"I saw that you had read some of the books about smithing in our house, and there was a page of the book marked with a clip in the corner, so I figured it was something that you wanted"

"Thank you father"

"now my son do you want to hear some stories from the time of your ancestors?"

"Yes! But what kind of stories?"

"It's the type of stories that will turn your world view upside down. Stories of monsters capable of regenerating cuts, broken bones and severed limbs, stories of how those monsters murdered and ate people alive"

"on second thought dad.... I don't want to ruin the good mood we're having so I'd prefer it if we stopped talking about this"

I saw father with a glimpse of sadness in his eyes as he looked at me, knowing that I didn't have the heart to listen and hear about those gruesome stories made him a little worried about my future, But unbeknowst to him I just really enjoyed my time with father so much that I didn't want to ruin it.
