Prologue: the Uchiha
In the village of Nogata was a small home, and in that home was a dark-haired young woman with dark blue eyes and a dark red kimono. And her name is Tsutako Tomioka. Tsutako was walking around the estate as she looked around.
Tsutako: Giyuu-Giyuu, where are you? Huh, if I were Giyuu, where can he be "worried"?
Tsutako closed her eyes for a few minutes. As she reopened them, her eyes started turning red, with a comma next to it. As she looked around to see where Giyuu was, she saw a bush moving around. Tsutako saw this as she closed her eyes, turning them back to their normal dark blue color with a smirk on her face as she walked away.as Tsutako slowly walked away.
In the bush was a boy with messy black hair tied back in a low ponytail and different eye colors: one is blue and one has mysterious purple concentric circles covering the eyeball. This was Giyuu. Giyuu slowly looked up, seeing his sister was gone, as he sat back down giggling.
Giyuu: hehe.
???: I found you.
Giyuu got grabbed as he got startled to death. The one who grabbed him was his sister Tsutako, as she started giggling.
Giyuu: whoa "startled.
Tsutako: "Haha, you think you can hide from me, Giyuu," chuckle.
Giyuu: "Oi, that fare née-san, you use your sharingon on me!"whines.
Tsutako: That's true, but I'm only using one comma.
Giyuu: fine, I guess that's count "irritated,
Tsutako: "Come on, it's time for bed; it's getting pretty late."
Giyuu: Can you tell a story once we get to the room?
Tsutako: "Hmm, sure, why not?"
inside the estate.
when the two siblings went inside the estate as Giyuu went and laid down on the futon.
Tsutako: Okay, what kind of story do you want? There are so many books on the shelf.
Giyuu: Hmm, maybe something new. We already read these books so many times, and I kind of want a new story.
Tsutako: "Hmm, okay, I got one; how about a story about our ancestors.
as the candle went down as Tsutako lay next to Giyuu, as she told the story.
Long ago, the Tomioka was not originally our founder's name, but the Uchiha. We were called the Uchiha because of an extraordinary eye called the sharingan that can cause an illusion known as genjutsu. We were the most powerful and proud clan that ever existed, until a clan called the Senju clan came. They are the most powerful clan that can unravel the Uchiha. From then on, the two clan declare war on each other, blood lust of their power.
A few years have passed since the two clan fought, and peace has finally arrived between them. learning equal turns from one another.

From then on, Giyuu fell asleep, and Tsutako put a blanket on him as she slowly kissed his forehead. Tsutako walked away on the Giyuu futon as she went to the other side of the room.
On the other side of the room was an empty room. Tsutako went into the empty room as she sat down to open one of the tatami floors. Inside the mat was a door. When Tsutako grabs the handle on the doorknob and opens it, it reveals itself to be a box. Inside a box was a book, and Tsutako looked at it as she hugged it in sadness.
Tsutako: Once you get older, Giyuu, I'll show you the truth about our clan's origins. The truth of our clan's downfall, the true secret of the Sharingon and your left eye, the war, and about that monster, that man who slaughtered our clan.
the demon king.
Muzen.
