Staring through thousands of portals he finally stopped on one, inside this one, there were people being slaughtered by what seemed like giant humanoid ants.

"What is that ?" Naruto asked himself, not sure about what was going on. Even if he was a self proclaimed god, he was not omniscient. With a frown installing itself on his face, he looked around what seemed like an island devoid of technology. He observed these "ants" and decided he should help these people before it was too late.

Standing up, he began to walk towards the portal and passed through it. A second later, he was in a field where a dozen of people lied there, dead with blood flowing out of them. Around him was a forest and a village with houses made out of wood. Then, as if remembering what he was here for, he turned his head to see three people running, a man in his late forties, a mother at the same age and surely their daughter who was no more than four or five years old.

They were apparently flying away from one of these strange creatures resembling ants. Since Naruto didn't interact with humans for so long he hesitated for a few seconds and it was all it took for the laughing ant to cut the two adults in pieces. With a surprised look on his face, Naruto began to run towards it, hoping to save at least the daughter and of course he was fast enough as he seemed to appear behind the ant and crushed it with a slap to its back.

Blood flew out of this monster and covered the still living girl in it. When she realised what happened, she began to cry while poking her mother and begging for her to wake up. Not knowing what was happening inside of him, Naruto felt his heart ache when looking at this scene. He remembered millions of years ago when he was also five years old and was crying every night to see his parents.

'I... It seems like I can't let a young girl like her alone... I didn't save your parents, I'm sorry but, in exchange I'll protect you.' He thought as he smiled warmly towards her and began to kneel in behind her. He called out to her with a calm and caring voice, "Little girl, what is your name ?"

Continuing to cry, this black haired pale skinned girl looked at him in the eyes and said, "Mister... my mum, my mum... she doesn't want to wake up... please help me..."

With a hint of pity in his eyes, Naruto began to pet this little girl's head and said, "I'm sorry but, your parents are already in a better place."

Understanding what he said, the girl began to cry with all her power and hugged him tightly as she didn't know what to do. However, Naruto decided to protect her as if he was her father so he was going to do it, so he took her in his arms and disappeared from this place. He appeared hundreds of meters away in a dark cave which was quickly lit with a few spheres of chakra.

When he looked towards the girl he held within his arms, she was sleeping so he decided to create a warm bed for her with the creation of all things he learned to use in his training. Moreover, with his current power, nothing was needed to be spoken so he didn't have to wake her up.

'It seems like I'll have a lot of work in this world... but it's better than meditating for eternity.' Waiting for the girl to wake up he sat cross legged in front of her for a few hours.

When she began to open her eyes, she stood up and faced Naruto who was calmly observing her with a warm expression. He decided to talk first as it seemed like she didn't want to do it, "So, what is your name ?"

Hesitating a little she decided to answer the man who saved her, "My name is Aiko... and you mister ?"

Noticing the slight hesitation in her voice he decided to ease it by changing his appearance from an adult to a ten years old kid, "Well my name is Naruto and since you are alone, I will protect you. How does it sound ?"

She was first surprised by the change in appearance but decided to answer him, "Thanks... I suppose that... my parents wouldn't want me to die in this place..."

Surprised with this little girl's understanding he stood up and patted her on the head. He then held her in his arms and installed her on his back. They were now leaving this cave as he had a lot of work to do in this world. A young Naruto wearing a long sleeved orange shirt with a black coat and black pants was seen carrying a young girl clothed in a white dress with brown shoes.

Walking for what seemed like hours, they finally could see the sight of human civilization even if it was already destroyed with corpses present everywhere. However, he heard the sound of people fighting in this desolated place. Following this sound, he saw dozens of corpses and heads on spikes. 'What is that ? Why are these corpses... never mind... I did worse than that in my life.'

"Aiko, when we see people, tell them I'm your older brother... if not it will be bothersome, okay ? " Naruto asked with a gentle voice while Aiko hide her face in his back to not see all these dead bodies, she weakly nodded to agree with him.

Seeing her reaction, Naruto began to increase his speed until he saw three humans and one of the monsters. However, what surprised him was that the two who were fighting were around ten years old while the older one was sitting on a rock, observing them as if it was a test.

'Hmm ? They feel strong... and what is that kind of energy they are radiating ? It seems like chakra but it's a lot different. Well... I'll observe for now and help them if they are losing.'

As he said that he totally hide his presence, it was as if he was part of nature itself. He formed one with his surroundings and calmly observed the fight. The black haired kid wearing a white tee shirt was dashing towards the ant while the white haired one was followed him. They began to attack but it proved ineffective as they were sent flying away.

But, the white haired one decided to try something else and jumped high in the air then, lightning was sent towards the monster while he said "Thunderbolt". After being stunned by this attack he couldn't move and the black haired one prepared a sphere of energy on his fist and punched it.

The monster was sent flying away but before he could fall on the ground, a flying one held him and flew away. Nevertheless, a huge cry full of killing intent was sent towards the two as the rabbit like ant's blood boiled in anger.

'Well it surprised me... they are stronger than what I thought, maybe I can help them... well since I am taking the appearance of a ten years old kid I might as well use it.' Naruto thought before beginning to walk towards the three humans. However, as soon as he stepped out of the forest the adult one turned his head towards him.

He was tall and thin, with white long hair and a hat hiding the top of his head. He was wearing black pants and a pale grey sweater. 'To think that he could sense me coming even when I make no sounds... interesting.'

"Who are you ?" Asked the adult while looking towards Naruto with surprise as he didn't sense him until he was right behind them. The other two also turned to face him and prepared to fight until all of their eyes landed on the girl installed on his back.

"Ah sorry... I didn't want to surprise you, my name is Naruto and she is my sister Aiko, pleased to encounter someone in this place... might I ask what are your names ?" Asked Naruto with a cheerful smile.

"I am Kaito, a hunter and they are Gon and Killua, also hunters. Why are you here ?" Answered the tall white haired human.

"Ah well... I was playing with my sister in the village until we heard screams and saw people dying all around us... when I tried to help, they were already all dead and we were only able to escape." Said Naruto as he did his best to hide the truth.

"How could you escape ? And why didn't you escape towards a safer place than the forest where there are a lot of chimera ants ?"

'So they are called chimera ants ? Well it's not like it matters... should I tell them that I can use the same energy as them or should I just tell them that I trained since I was young... they seem to be strong for ten years old kids so it shouldn't be a problem if I...'

Naruto lost his smile and began to frown as he answered, "I didn't escape to a safer place since I want to avenge my parents... moreover, I am more than strong enough to kill them."

Slightly surprised by his answer, Kaito pondered on something for some time until he asked, "To what extent ?"

Not understanding what was asked, Naruto tilted his head.

Reformulating his question, Kaito said, "To what extent is your strength ?"

Finally understanding, Naruto answered with the truth for the first time, "I'm not really sure but I could kill one of them with a fraction of my strength."

Looking towards Naruto, Kaito didn't detect any lies so he began to walk with the other two kids who wore serious expressions on their faces and said, "Then come, but you will have to protect your sister alone."

Killua then leaned towards Kaito and whispered, "Are you sure Kaito ? I can feel something dangerous inside of him... moreover his steps... he doesn't make a sound when he walks. He could be an assassin like me."

"Don't worry. I don't feel any ill intentions coming from him and we need all the help we can get."

A few hours later, they all arrived inside NGL's drug factory as Kaito called it. It was where all the drug was made on this island. After searching for a few minutes in this factory which was made out of stone and rock like a cave, they heard the sound of chimera ants walking towards them and laughing. There was three of them, one resembling a centaur while a woman was like a humanoid butterfly and the last one was slightly resembling a centipede.

"What is that ?" Asked Gon as he saw two humans walking like dogs in front of them. Naruto observed them and didn't see any threat to Aiko in her but... the madness emanating from them was not what he preferred to see so he stepped in front of them as the ants began to insult and treat them as weaklings.

Kaito ordered Gon, Killua and Naruto, "Gon and Killua... you will take the two on the sides while Naruto will show me if he can be of any help by killing the one in the middle. Any complaints ?"

Naruto didn't mind it as he shook his head and took a step forward. However, before he could begin to fight, Killua was already killing his target with a deep and dark killing intent radiating of him. It didn't take long for him to get rid of the chimera ant.

When he looked towards Gon and his opponent, he saw that they were hesitating to attack. Seeing that his underling was hesitating the centaur began to mock him and walked towards Naruto full of confidence.

'Is he taking me as a weakling ? Does he want to disappear ? Then I'll grant his wish.' Thought Naruto as he let Aiko standing up on her own and told her to stay behind.

Kaito took great interest on what he could do and how he could fight so he observed him and tried to see if he was of any help to them. A second later Naruto turned towards the chimera ant and glared at it in the eyes, at this moment everything seemed to stop around it.

Fear was clearly replacing his mocking face as he felt Naruto's killing intent on him and when he heard him say, "Do you want to play a game ? The first one to get hit will die, ok ?" he was more than angry and decided to rush at him.

Nevertheless, Naruto took a step forward and disappeared, the next moment he was above the ant with a katana made out of chakra in his hands. Using it, he cut the ant in two and crushed its head.

Author's note :I'm sure you all guessed it but the world in which he is right now if hunterxhunter's world. Thanks for reading !
