"Both of you just keep running!" I heard my father yell as we ran through a thick forest. "No matter what happens don't turn back. Just keep going until you're out of their reach."

Not completely understanding the situation I obeyed my father without a second thought. I had no real idea of who "they" were or why we had to run. I only knew that my father sensed danger. If he sensed danger then it meant it was real. If he told us to run it was because he was scard of what happened if we stayed put. If he told us to run then we were all scared. That day I was scared more than ever. My father's tone and the look in his eyes showed how much danger we were in. I ran unquestionably. Trying my best to keep up with my elder brother as my parents ushered us forward.

My elder brother was ahead of me. He reached for my hand when he noticed I was slowing down and started to practically drag me through the woods. My legs could barely keep up with him. He was a lot faster than I was. His legs were a bit longer and allowed him to cover more ground. I had to move my feet faster but it was hard. In the back of my mind I remember noticing the sound of my parent's feet and voices getting father and farther away.

The trees of the surrounding forest were becoming thicker and thicker. Before they were some spaced from each other but soon the path seemed to be lined by nothing but the trunks of the trees. They were zooming by me pretty fast. Far faster than any normal human could run. How can anyone keep up with us at this point? Perhaps our pursuers had been left behind? I know I was having trouble running so fast. Hell I almost tripped a few times.

"Itachi slow down." I begged with labored breathing as I struggled to keep up with him. "I can't keep up"

"I don't think that's a good idea brother." He said as he gripped my hand tighter. "I won't let go I promise. Just try your best to keep up."

I didn't dare look back but I did notice that I could no longer hear my parents behind us. Where had they gone? My elder brother's grip constantly brought me back to reality and reminded me to run whenever I started to slow down.

The sound of two gun shots in the distance caused me and my brother to stop dead in our tracks. I looked back but could only see the forest we had been running through. I felt like a lead weight had been placed in my stomach when I didn't see my parents. For a few moments I became detached from the world

I knew they were dead... Those gun shots had been aimed at them. But it didn't seem real. This couldn't be real. It was a bad dream. Soon my brother will wake me up in the morning. And mom and dad will be fine. Things will be normal.

"We can't stay here Sasuke." Itachi said as he began to pull me. "It's not safe for us here."

"Then where do we go?" I asked as I began to cry and as he pulled me along. "What about mom and dad?"

"I don't think we have to worry about mother and father anymore." He said grimly.

I felt the tears falling from the corner of my eyes. What he said made me realize that I was not asleep. That this is not a dream I'll be waking up from. That this nightmare was reality and I could not escape. I could only live with it and move forward or die. I forced back the tears because my father always used to say that a man isn't supposed to cry but they just kept falling as we walked. Would father have scolded me or comforted me at that moment? Perhaps he would just let mother old me in an embrace and say nothing.

The further we walked the more spacious the forest became again. We were nearing the giant valley that was near our home town. I didn't hear anyone following us. Did that mean we were safe? Could we stop? There was a river here that looked very clear. Maybe we could catch our breath.

"Brother?" I asked, knowing Itachi had sharper senses than I did. "Is it safe?"

"For now." He said as he looked at the water. "We can rest here before we take any action."

I didn't really realize how thirsty I was until I scooped up some of the water into my mouth. Then I started to greedily drink as much from the the river as possible. I knew part of the thirst was "unnatural" and required something else but I didn't think too much about it for now. For now I just drank the water and let my legs rest.

"Someone saw us drinking blood." Itachi stated. "They know our secret. Or at least they kind of know."

"Was it me and you?" I asked. "You know that got caught? Was it because I was thirstier than usual? Was this my fault?"

"It's not your fault Sasuke." He said. "But we are in danger."

"Then what do we do?" I asked frightened. "Those gun shots. They killed mom and dad right? They'll do the same with us. Or not. We're still kids but then they might hurt us in a worse way. What do we do big brother? We can't fight them!"

Itachi looked up at the sky as he pulled up a piece of paper he had been keeping in his pocket.

"Father told me to use this if we were ever forced to fend for ourselves." Itachi said as he looked at the paper. "It looks like it's a summoning ritual for our family's demon."

"You mean the one that passed his sharingan to us along with this thirst for blood?" I asked.

"Yes." Itachi said. "Well, I guess now is a good a time as any."

"What do we need to do brother?" I asked.

"Since we both need his assistance we have to draw out the summoning circle with both of our blood." Itachi said as he stared at the paper. "Once it's done we just need to chant the words needed to summon him."

"Okay." I said. "Can I see the paper too brother?"

He showed me what was on the paper and pointed at the summoning circle.

"You can draw the easier part of the circle Sasuke." Itachi said with a smile. "I'll handle the harder part."

"How big should it be?" I asked him.

Instead of answering my question my brother grabbed some leaves and made a circle.

"Make it inside the circle of leaves." He told me. "Just make it as close to the image as possible ok?"

"Ok." I said.

I bit my finger and started to copy the image I saw on the paper as best as I could. The pain in my fingers from biting them kind of hurt but it was fine. I healed faster than other people. It's because of the blood that runs through the veins of my family.

I bet your wondering what the hell was up with my family huh? Well unfortunate reader that happened to find this story I'll explain to the best of my knowledge.

The story goes that a demon came up to a member of our family. He offered his eyes and the blood of a demon to the entire family if he signed a contract with him. Upon the agreement every descendant from that demon would be considered his. This meant that anyone born with a drop of the demon's blood in their veins was his "child" or "tool." He could put you into a binding contract should he need you or you may ask for his assistance if you summon him. At the time I never truly understood this.

"Alright." Itachi said when he finished his part. "I think it's finished."

"What are we supposed to chant?" I asked.

My brother told me the words. I didn't recognize them. They sounded like they belonged to a language that has been dead for a long time.

We stood inside the circle and started chanting the words in a trance like state. What was amazing was that the circle made from our blood started to glow a bright red. Not breaking the rhythm of the chant I kept my eyes on the circle. The light was glowing brighter and brighter and soon I had to close my eyes. We didn't stop the chanting until we heard a loud noise.

"I didn't expect two little boys to summon me." I heard a deep baritone voice say. "Though I can't say I'm surprised. You only call me when you need me."

I opened my eyes and I saw a man with hair that reminded me of a lion's mane. His eyes had the Sharingan pattern activated. He was definitely the demon that our family served. Despite standing inhumanly still there was a strange grace in his stance. He was handsome as well. He eyed us like a predator but he also seemed amused at the time. There was a sense of concern coming from him but it didn't seem to last long.

"Our family has been hunted down." My brother stated bluntly when the demon said nothing more. "They've been killed under fake names but were related to us. They drank blood and even had the sharingan. Our parents were just killed back in the woods. I'm pretty sure we're the last members of our family. This town is obsessed with flushing out demons."

"So they wound of hunting you all down then?" He asked a little angry. "How could it have come to this? Those humans shouldn't have been able to catch you all. You all had the means to survive these attacks. You're above them. Why should I intervene? Why did you not fight back?"

"You promised us safety should we ever need to call you!" Itachi yelled, I just silently watched as the two argued not really sure what to say. "That was what father had told us. I don't understand why we didn't fight back but what's done is done. I understand we need to repay you in some way. My brother and I are still young but we can still serve you if you can get us somewhere safe. I'm just asking for a home. Nothing else."

"Only thirteen years old and you're already willing to give yourself to me?" He asked mockingly.

My brother looked at the demon straight in the eyes. The demon smiled while brother scowled.

"Perhaps this was a mistake." Itachi said as he was about to destroy the circle. "He won't-"

"I'll help you only if you agree to my conditions." The demon said as he grabbed my brothers arm. "Though I doubt you'll like them."

"What are your conditions then?" He asked.

The demon let go of my brother and started to walk around us like a predator. I noticed the circle we had created had disappeared. I panicked a little but did my best to hide it.

"Do either of you understand what it truly means to serve a demon?" The demon asked as he circled us like a predator.

Neither of us answered. I thought Itachi would have understood but even he seemed a bit confused.

"If I take you under my protection then you both will belong to me." He told us. "What that means is if I ask you to do something then you do it. It also means that you will also be entertaining me."

"What do you mean by entertain!?" My brother asked a little frightened now.

Why was my older brother worried all of a sudden? Entertain only meant amuse him right I thought to myself. It couldn't be that bad.

"Well" The demon said as he stepped in front of my brother. "I think you have an idea of what I mean. It means if I want to see you fight then you do so. If I want to use you to satisfy my libido then I expect you to cooperate. If I tell you to win a race then you will do so. Understand now?"

He began to circle us again.

"What do we get in return for that?" My brother asked. "I want every detail."

"I'll give you a proper home." The demon said with a strange smile. "You'll have a roof over your head. You'll have food, clothes, water, shelter. Since you're both still children you'll even still go to school. I'll keep you safe from these hunters but I will be working on eradicating them at some point. They will not get away with harming my children. But for now I'll work on raising you boys to be decent fighters."

"How long will we get this 'protection?'" my brother asked, never letting his gaze leave the demon. "And why would we need to learn to fight?"

"For as long as you live." He said to us. "As long as you drink my blood you won't age. So you won't die from you body growing older. I also expect your help in destroying these humans who dared to harm my children."

"Big brother." I said, finally finding my voice. "I think this is the best option. We'll die out here if we don't accept. We can't hunt and can't buy anything with no money."

"I know Sasuke." Itachi said to me as he turned to the demon. "We accept the offer."

A scroll appeared before us.

"Both of you need to sign the contract." The demon stated. "It must be signed in blood."

Before I could even bite my thumb my brother snatched my hand as he read the paper in front of us. The demon seemed patient enough. He allowed my brother to read the paper as long as he wanted. When Itachi was done he let go of my hand and signed the contract first. He bit into his thumb and smeared blood on the paper. The blood turned into lettering and spelled out his full name. I did the same and smeared my own blood on the paper. My smeared blood formed my name as well. Finally the demon signed the same paper and his blood spelled out Madara Uchiha.

"Well now that we have the contract made why don't we get you boys home?" he asked as he held out his hands.

We took his hands, they were big and strong just like father's used to be. Looking at my brother I could see that he thought the same thing. The only real difference between the demon's hand and the hand of my father was that the hands of the demon felt colder.
