AU.13 years ago in a typical cold evening, an intense light suddenly covers the whole world as an army of demons came rushing from a large black portal appeared at the dark sky just after the light vanished. No one knows what really happened, but a few people recognizes it, a sign that the curse human with demon blood has finally awaken and the only way for the demons to return to hell is to kill him.

DO NOT OWN KATEKYO HITMAN REBORN

CHAPTER 1: DEMON HUNTERS

Life will never be the same.

That's what a lot of people were always thinking for the past 13 years after the unfortunate incident. People manage to live with the help of the 7 different kinds of flames combined to make a barrier in the place called Namimori, possibly the only area where the people can live without the threat of demons.

The 7 flames: Storm, Rain, Lightning, Cloud, Mist, Sun and the rarest Sky flame which is fortunate for them to find few people who has it and helped to complete the barrier.

But they do know that the protection that they have is not permanent. There will become a time that a powerful demon might successfully destroy the barrier or worst, the human who has the curse demon blood will try to and dominate the whole world.

So far they have no leads, besides the fact that the only son of the Sawada Family was rumoured to be the cursed one. Though the clue stops there since the said Family died a long time ago, not killed by demons but assassinated.

And so the only solution that they could think of is that the flame wielders to engaged into different trainings courtesy by the strongest seven (Arcobaleno) as direct orders from a powerful royal blood family that currently ruling Namimori, for them to hunt demons outside the barrier after years of training and hopefully find any survivors. Though they are instructed that their real mission is to find him, the cursed person and kill him to avoid the same tragedy that happened long time ago.

Young flame wielders are no exceptions. They have no choice as they are living in a world where time is very important. Even if they are still young but already an adept demon hunter, then they will be starting their mission already. It is a race between humans and demons on who will survive and who will be annihilated.

Places outside the barrier are now different from before.

Dark clouds traps the sunlight and eventually doesn't allow any entry reach the ground, fully developed cities and the green and peaceful surrounding are now replaced in ruins as no signs of life evident in every places.

These are the places that the demon hunters would go and fulfil their mission.

And one of them named Yamamoto Takeshi, a 13 year old master swordsman with black and serious brown eyes like a natural born hit man and a rain flame wielder. He's been hunting demons for a month already as he successfully kills any demons that come in his way while he goes on with his journey alone with his mission in his mind.

I need to fulfil the mission, for the sake of my family waiting for me and for a peaceful future. That is what he always thinks of when he feels lonely as it seems like he's walking in a path where it doesn't have an end as he has currently at the rumoured commanding general demon territory and was passing by a torn looking building only to hear a loud shout as if asking for help coming from the inside.

"NOOOOOOO!"

They're in trouble!

The sword master hurriedly run inside the structure only to find a lot of people covered with their own blood recognizing them the same as him, a demon hunter as he spotted a woman leaning against a wall with her blood flows outside her large wound in her stomach.

"R-run.. He's t-too power..ful." As the woman died after giving a warning at the teenage swordsman.

"HAHAHAHA!" A dark and murderous voice echoed the entire area which made the sword master to prepare and proceeded with his fighting stance.

"Another stupid demon hunter huh?" A demon suddenly made his entrance just in front of the swordsman with a pair of large goat horns, wide wings like those of the bats while his lower part of his body resembles like a human figure and also his face with only a pair of red piercing eyes and has long sharp fangs.

"Wow it's a lot younger at this time. You filthy human can't touch me, the great Demon Baal, commanding general of the infernal armies." The demon introduced himself while he glared at the teen with his piercing red eyes but becomes amused since he didn't see any signs that the teen was scared or affected by his glare, instead he smiled darkly and muttered words that was unexpected for the demon to hear.

"Die demon."

Demon Baal instantly became excited, feeling like he will have a good time playing and torturing the teen before killing it.

"You insolent human make me feel excited!hahahahah!" As the demon prepares himself to attack only to see the teen already at his behind with a katana positioned horizontally.

Shigure Soen Ryu 8 offensive form: Shinotsuku Ame.

Instantly the demon was surrounded by powerful blue flames collapsing as he tries to stands up but fails miserably and looked at the man who attacked him for the last time before his body disappears with the blue flames at the same time.

Yamamato's body suddenly wobbles and left him with no choice but to rest at the former territory of the demon Baal. It seems that his body is now starting to feel the strain of fighting demons everyday and his lack of rest.

I should rest for a while.

He thought as he close his eyes and letting his tired body to rest and when he was about to drift to his consciousness, he heard a faint laugh.

This caused him to raise his guard up.

"..haha.."

There it goes that laugh again. A demon? Thinking that there are no possible survivors because of how ruthless the demon Baal was.

So demon Baal with his acquaintance huh. How unusual.

He thought since he knows that high ranking demons have this certain pride that doesn't want to be with someone else with him in his territory since they are greedy and only wants to be the most powerful in a certain area.

So the swordsman silently went to where the voice is coming from while holding his unsheathed katana for him to kill the demon instantly. When reached a part where there's only a single opened door, he instantly position his sword for his another offensive form as he slowly approached the dark room illuminated by a light of a single candle only to find a boy with a gravity defying hair, has an expressive big brown eyes and unexpectedly laughing as he plays with a small demon sky lion.

"I-It tickles- stop! haha!" The small brunet said while holding the small demon sky lion.

Yamamoto was shocked. How did he survive against that demon, not to mention playing with a demon animal?

While the swordsman didn't move for a while, the brunet suddenly looked at the direction where the said teen is and blinks for three times with a hint of fear in his eyes unsurely on how he will react as his demon sky lion went in front of the teen and growls angrily.

"W-who are you mister?" the little brunet only managed to say.
