Last time

The man, Minato, stood in the shadows holding the boy keeping himself unknown to Mary. Minato walked in the opposite direction. He glanced up and saw Mundus be enveloped in a bright light. He also heard someone shout "Mary" and "Trish" and the women ran off in the direction of the shout. Minato muttered, "You will make a great addition to Konoha."

Now on with the story, Time skip: 6 years.

A young boy of the age of 6 stood in the middle of what seem like a war zone. The boy's normal black hair stood up and turn into a strange silver color. His right hand and lower half of his forearm had been severely burnt. He surveyed the damage around him with his now pure silver eyes. Bodies burned past the point of recognition. Buildings and the ground itself was covered in a black flame. The only thing saved from the destruction was a girl about twice his age holding a katana with a pure white tsuka, tsuba, and sheath. The girl lay dead from a kunai in her chest. Her cloths had been torn from what those animals had done to her. The boy looked at her with a saddening look in his eyes. He felt something slide down his cheeks and moved to wipe what he thought was tears. He looked at his hand and noticed that the tears were actually blood. He noticed that his hand was badly burnt.

The girl had been his very first friend and one of his only friends. The boy never understood with the villagers hated him so much, but that didn't matter when he was with her. In his mind, she was a tenshi, the center of his universe. She showed him kindness when he only received hate from others. She shared her dreams and goals with him. He still could hear her tell him her real goal in life and promise she made him make. He sheathed the sword and picked her up, bridal style, and jumped from building to building, determined to leave the hellhole that was his 'home'. As he jumped, he became lost in his memories.

Flashback: 9 months

The boy and girl stood in a clearing and were sparring with practice swords. He was holding two swords, and she was holding one. He crossed his swords to form an X and dashed forward. She brought her sword up to block his attack. As he moved closer, she moved her sword over head and prepared to strike. As she swung her sword down to strike, their swords clashed. She overpowered him, and her sword crashed into his left shoulder, which made him drop the sword in his left hand. He answered this by spanning his remaining sword into a reverse grip, and threw a right hook. She moved forward and struck his wrist making him drop his remaining sword. She then struck him on his head which cause him fall on butt and grab his head.

She allowed a small smile to grace her lips which quickly it turned into a full blown laugh. "Kazuma, you need a lot more practice before you try and beat me with that!"

The boy, Kazuma, glared up at her, "Just you wait, Kuina. One day I'm going to be beat you." The girl, Kuina, got a downcast look and turned away from him. Kazuma slowly got up, rubbing the top of his head, and walked towards her.

"Do you know what my dream is? The goal that means more than anything to me." Kazuma shook his head and muttered a no to Kuina question. "It is to be the world's greatest swordsman, but I can't. I'm a girl and girls are physically weaker than men." Kuina started to tear up at this point. "My breasts are already filling out. One day I won't be able..."

"SHUT UP!" Kazuma yelled, "The only reason I'm going to be better than you is because I trained harder than you! If girls are weaker than boys, than why do you beat me in every duel?! Why were you rookie of the year when you graduated?! Being a girl never stopped you than and why should it now?!" Kazuma was panting when he finished, exhausted from the duel and the yelling. Kuina crying had stopped and she looked over at Kazuma.

"Kazuma," Kuina uttered. "Let's make a promise that one day, one of us will be the world's greatest."

Flashback end

Coming out of his memories, Kazuma looked back and saw Konoha in the distance. He looked down at Kuina and tightened his grip. Kazuma continued to run until he hit the edge of a town. Following this, he passed out from exhausted. Kazuma's eyes flashed and he was welcome by an unfamiliar sight. He sat up and looked around; seeing what he would except a normal room to look like. He glanced over and noticed a mirror. He looked and saw that his pitch black hair was now grey. He than brought his hand up to his forehead and noticed that his hand had been bandaged. He got up and opened to door leading out of the room. Leaning his head out, he quickly took in his surroundings. Despite what people would think, Kazuma was very cautious of his surroundings. Kazuma quietly made his way there foreign hallways, until he reached what looked like a living room. Kazuma cautiously inched across the room until he heard the sound of a door opening. He spun around and saw a middle-aged woman carrying bags and a young girl. He unconsciously tensed and slowly relaxed as he remembered that he was no longer in Konoha.

The woman noticed this immediately and handed the bags to the girl. The girl grabbed hold of the bags and walked into another room. The woman spoke, "I'm sorry but your friend didn't make it." The woman glanced at Kazuma and saw that he was on his knees, crying his eyes out. The woman quickly moved over to Kazuma and gripped him in a loving hug. Kazuma stiffened at her touch before returning to his sobbing. The woman was trying her best to ease the boy's suffering. She rubbed his back and kept tell him that it would be okay. Kazuma's cries slowly ceased but oddly to him the woman didn't lessen her grip. He started to panic, think the worst. This only caused the woman to tighten her grip not knowing what was wrong. After about 5 minutes, Kazuma ceased to struggle against the woman's grip. "Feel better?" To which Kazuma nodded. The woman looked at him before saying, "My name is Sakamoto Arisu. What's yours?"

"Kazuma."

The woman looked at him curious before asking, "Do you not have a surname?"

Kazuma looked uneasily at the floor before saying, "No, I'm an orphan." The woman, Arisu, instantly felt bad and grab Kazuma in another loving hug. Kazuma, for the life of him, could not understand why this woman cared for him so much, but he was not going to pass it up. He momentarily thought that this was have a mother must be like. He pushed that aside and returned Arisu's hug. The girl walked back into the room and noticed Arisu hugging the boy.

"Hi kaa-san, who is he?" Arisu looked at the girl and slowly released Kazuma.

"Well Kameko-chan, this is Kazuma." Kazuma looked at the girl with a mixture of envy and hope. Envy for the fact that she had a kaa-san, and hope because he hoped she was like her mother. Kazuma was brought out of his stupor by Arisu, "Kazuma, it's not nice to stare." Kazuma's face got slightly red and looked away.

"Aww, he's so cute when he blushes." This comment from Kameko made Kazuma's face become even redder. Kameko walked over and asked, "Kazuma that is your name, right?" Kazuma nodded. "Why is your hair grey?"

"I don't know. Up until yesterday it was black."

"Yesterday," Arisu repeated. "Kazuma you've been unconscious for a week." Kazuma was shock was this discovery.

"Well, what happened to Kuina-chan?"

"Like I said she didn't make it. We buried her and were waiting for you to wake up so we could learn her name for her gravestone. You said her name was…"

"HER NAME IS KUINA," Kazuma yelled.

Arisu's eyes widened, "Yes her name is Kuina. Who was she to you?" Kazuma visibly stiffened and feared answering the question knowing that they might, like the villager from Konoha, hate him for it.

"Kuina was nee-chan in every sense but blood. She was first and one of my few friends. She was also my sensei in kenjustu." The pair eyed Kazuma and was about to speak before Kazuma continued, "You're probably wondering why I said one of the few." The pair nodded. Kazuma sighed, "In my village, which is Konoha, I am view as a demon and they're right. Well in a sense, I'm a half demon; if I heard the Hokage correctly." The pair started to back away from him. "I beaten and nearly killed on a daily basis. One time my heart really did stop. I was raped once by a group of women who after they were finished stabbed a kunai through my heart. When they found I had survived, they home and told their husbands or boyfriends, brothers, and fathers. They attacked me and when Kuina tried to save me, she was raped and killed. They said 'That now we're even, Akuma.' After that I remember creating this black fire and killing them all." Kazuma was once again crying that the tears were blood like the night Kuina was killed. Kazuma's hair stood up and turned back to that silver color. His eyes turned silver and the kanjis for 'demon sealing' appeared over his body. "I burnt them all. I made them pay for what they did to her." Kazuma was being slowly in enveloped in black aura. "I remember every jutsu they used, every failed attempt to attack me, every scream, every one of their faces frozen in fear, and every one of them begging for mercy." Kazuma fell to his knees, grabbing his head. "Please, make it stop. I don't want to see them. Please, STOP!" Kazuma yelled before collapsing.

The pair walked over to Kazuma's unconscious form.

Unknown location

Kazuma awoke laying face up in water. He thought that the mother and daughter probably left him there until he looked around and saw a giant gate with chains holding it shut and the kanji for demon on the middle of it. "Quite a view. Wouldn't you agree, Kazuma?" Kazuma spun around and came face to face with himself. The other him had red eyes and wore a mischievous smile. "Before you ask were we are, we're in you mind. Actually, it would be our mind. You see over the years of physically and mental abuse. Ours mind separated into entities. You, the one that can only slight use that power." The other him pointed to the gate. "And me, the one that has full control over that power. But because of that damn seal is causing us to slowly die because it has cut us off from that power. Unless we break the seal, but there is a 50 percent change that it will kill us. Before you ask why I'm helping you. Like I said 'We are the same person,' albeit with different personalities. One day, we'll go back to being one person, so until then I can't have you dieing. Now there is something very important I have to tell you. If you use your true powers for to long with the seal on, you run the risk of losing control and going into a berserker rage. If that happens, I will have to struggle for control. Now if you have any questions, ask them later. Our time is up." The other him turned and walked away.

"Wait, what do you mean our time is up?" Kazuma asked before the world around him faded away.

In the real world

Kazuma awoke with a jump. He quickly realized that he was back in the same bed in the same room. He got out of bed and got dressed. He ran to the living room and heard voices coming from another room. He walked into the room and saw Arisu and Kameko eating. Arisu gestured from him to sit in the empty seat. Kazuma quickly sat and started to eat the food that Arisu placed in front of him. After they all finished, Kameko asked, "What happened to you yesterday?"

"Kameko!" Arisu exclaimed.

"It's alright," Kazuma said. "It appears that from the years of abuse that I suffered at the hand of Konoha's villagers and shinobi, my mind with separated into two distinctive entities, but why I saw the villagers and shinobi's faces. That is something I don't know about." Kazuma heard a whisper that said, 'It's what those humans call a kekkei genkai.' Kazuma looked around and saw that the other two were silent. For a few minutes they sat in silence before Kazuma asked, "Where is Wadō Ichimonji?" The pair eyed him curiously. "Kuina's sword." Arisu quickly got up and walked into another. She returned a moment later with Wadō Ichimonji. She handed it to Kazuma. He sat Wadō Ichimonji in his lap and asked another question, "May I go to Kuina grave?" The question was quiet but the others two heard it just fine. Arisu nodded her head and stood up. She motioned for Kazuma to follow her. Kazuma followed with sword in hand, and he was quickly followed by Kameko. They walked to the graveyard in silence. When they arrived, Arisu and Kameko noticed that he made no attempt to pray. He only walked forward and held Wadō Ichimonji horizontally in his left hand. "Kuina, I swore on Wadō Ichimonji that I will be the world's greatest swordsman. Just like our promise."

Time skip: 6 years

A 12 year-old Kazuma was walking down the rode that lead to Konoha. Kazuma wore a white short shirt, black pants, and black combat boots. He had a black bandanna tied around his left arm. Kazuma saw the Konoha main gate coming into view. He had three blades tied to his left side. 'Well Aku, what do you think Konoha will think when we walk through those gate?'

'Who knows. Just let me go back to sleep.' Kazuma chuckled at the entity that he called 'Aku.' Kazuma let his left hand rest on his most treasured sword, Wadō Ichimonji. He smirked at what kind of competition he would get.

"Just you wait, Konoha! You're going to see a brand new Kazuma!" Kazuma yelled.
