Prelude, Yoriichi Tsugikuni and his family

In a world full of demons and humans that can combat those demons exist. Those who combat demons are known as demon slayers. But today, the strongest demon slayer in existence, has finally perished. His name is Yoriichi Tsugikuni. He created the first breathing style, dubbed sun breathing which would later create a multitude of other breathing. Today, he died to his old age, not the demon in front of him. And that demon would be known as Kokushibo, or formerly known as Michikatsu Tsugikuni, Yoriichi's brother and the reason why he picked up the sword.

In anger that Kokushibo couldn't kill his brother with his own hands, he slashes his dead body in half with his sword, revealing a small wooden flute that he made for Yoriichi when he was little, stashed away on his person. Kokushibo starts to tear up at the fact that his brother never gave up on him, even after he became a demon. At this moment, even though he survived. Kokushibo felt as if he lost.

But that isn't where this story ends, no it is just the start. As the now dead Kokushibo is looking at a lone figure holding a sword and wearing an all black haori looking down at him with pitty.

Unknown swordsman: "What a pity, the strongest swordsman of his era, died due to age and not the blade. Tell me, what do you desire?"

Yoriichi: "I desire peace to befall on this land, and for Muzan Kibutsuji to finally meet his end."

Unknown Swordsman: "I can't guarantee that, but in the future, you will see things that will surprise you, come with me and ill show you all types of things" I nod but finally ask.

Yoriichi: "Could you please tell me your name kind sir?"

Yamamoto: "My name is…Genryūsai Shigekuni Yamamoto." Right after he taps my forehead with the handle of his sword which confuses me at first, but soon after I start to feel at peace. A feeling I wished for everyone.

Moments later I find myself surrounded by many trees. So i'm in a forest it seems. I guess ill stay here for awhile…

I start to gather the essentials such as shelter first, I quickly find an uninhabited cave for me to rest in. Next I look for water. It took me a while to find but it was on the opposite side of the cave I'm in. Now I should look for food. I start to run around the forest, not forgetting where im going until I finally "see" an animal I can eat for dinner. With the clear world I can easily see its weak spots so I take a deep breath in, using my sun breathing and rush towards the now known as deer and kick its left back leg, shattering its bone.

It cries out in pain as I give it a short prayer before smashing its skull in with my hand, killing it in the process. I drag it back towards the cave taking my time as it looks like morning is just about to eat.

Once in the cave, I looked for any sharp rock I could find, which wasn't very hard. As I have the clear world I can effectively see what rock is bad and what is good. I find the sharpest one, and begin to carve it into a knife, trying not to shatter it completely. Once finished I began cutting the deer into parts that are edible and parts that are un edible and should be used for bait. This took roughly 3 hours to complete and I had a neat stack of edible meat and non edible meat.

I then begin to cook the meat after collecting enough wood for a fire and for later when it gets cold. I take the skin of the deer and put it to the side for later. And prepare the meat for cooking by draining all the blood first. This is a slow task but worth it in the long term, as deer blood doesn't sound too appetizing for a person who ate normal cooking all his life. After finishing, I take some sticks and put them through the meat for it to sit over the fire and slowly cook. I'm not in much of a rush. It takes an hour for it to finish cooking properly before I dig in. Its not the best I've ever had, there aren't any spices here to make it any better. But this would repeat everyday for 20 years.

(Forgot to say this is mini Yoriichi)

You could see a small but adorable looking boy walking around a small town with an indifferent look on his face. But unknown to him this is if not the most dangerous, is close to it. This is the Kusajishi district. He is carrying a bag full of animal meat, though it's raw. He wrapped it in the fur of the dead animals he previously killed. He continues to walk down the lonely streets as he gets some stares much to his annoyance. He turns into an ally to avoid the stares. There he runs into a little girl with pink hair and dark brown eyes, staring at him.

Yoriichi: "Hello, my name is Yoriichi Tsugikuni. May I know your name?"

???: "I don't have a name…"

Yoriichi: "I'm sorry to hear that… I'm not sure If i can help with that, as I have no right to give you a name. But I can help you survive this hell stricken town." He says with a slight frown before it turns into a small smile.

The girl smiles with tears in the corner of her eyes as she thanks him for just the thought. She then declared him to be his brother much to his shock. But something, no someone is on his way towards this blood thirsty town, that is Kusajishi.

--Few days later--

Yoriichi: "Whats the purpose of this…" I say looking at a man who is holding a sword streaked with blood, as blood splatters on my face.

Until now, I was living an alright life with my new sister. We had food, clothes (though barely) even though she doesn't have a name. That was until a loud ruckus caught our attention. A man had entered and started killing everyone ruthlessly. Not even women were spared from him and were immediately cut down.

???: "Hey kid, whats your name."

Yoriichi: "My name? Well that is Yoriichi Tsugikuni. But why would a serial killer want to know the name of a lowly child." I say with a voice full of indifference. I have seen this sight many times in my life. The life of human being wasted endlessly by humans and demons alike.

???: "Hah! Just look at your spiritual pressure! You have so much potential but look at you! In the worst district along these weaklings!"

Yoriichi: "That might be right but I'd like to ask you to leave me and my sister alone from your mass killing of humans. We wish to live peacefully without hindrance from outsiders threatening our lives." I say releasing a small killing intent just thinking of him killing my sister.

???: "Hah? You wanna fight moron?"

I grab a sword that is lying on the ground, full of blood thinking of fighting the man. The sword is dull and looks like it will break in any minute. I grab it and get in my sun breathing stance.

Yoriichi: "If it means to protect my sister's live, very well. But may I ask your name."

???: "Very well, my name is Zaraki. Prepare to die! Yoriichi Tsugikuni!"

He dashes towards me as I take in a large breath, activating my sun breathing. He slashes down, aiming at the shoulder that holds my sword. It seems he wishes to disarm me quickly. I decide to use my 3rd form to defend myself and to counter attack.

Yoriichi: "Sun breathing 3rd form, Retsujitsu Kōkyō '' I slash horizontally blocking the first strike before I slash towards Zaraki's waist. He casually blocks it before kicking me away, with a surprised look on his face.

Zaraki: "The hell was that?" I don't get the answer to answer him as my sister comes out the alley looking at the scene. She then walks over to Zaraki, much to my desperation. But what happens next, I truly didn't see coming. She touches the sword, blood covering her hands and laughs. I blank out and before I know it, im "adopted" by zaraki along with my sister, who name is now Yachiru.

Time flies by and I become attached to Zaraki. Sure he has alot of fighting tendencies and even som suicidal ones. But he is a caring father who takes care of both me and Yachiru, which I love the most. He teaches Yachiru how to use the sword and teaches me a sword, which felt weird for some odd reason. It feels like its trying to bond with me for some odd reason.

And for 5 years we slowly make our way to what I now know as the Soul Society.

--End of chapter--

This is my first bleach fanfic so uh, yeah. I wanted to quickly go over it and not stay in one arc for too long. Yes this was supposed to be an arc. But what is there to talk about in the forest? And Yoriichi didn't even have a sword in Kusajishi until he found one against Zaraki. I also made him Yachiru's brother for some funny moments in the future.

It's funny how I thought about this for a while and recently I saw a fanfic with Kokushibo in Naruto. Oh the timing of it.

Yes, sun breathing.There will be future forms to add for character development and totally not plot armor, as he has more than 500 plus years before plot. As Yamamoto still has hair. Yeah, he's that old.

I don't know if all chapters will be this long as this is time consuming but the minimum is 1,500 words, such as in my other fanfics. Anyway, if you know about me you know what im about to sat, I hope you enjoyed, Stay safe!!!
