Here's a short glimpse into the twin's past from the point of view of Arashi.

Chapter 4: The Dark Past

"You can't catch me!" I was running away from Yuki

"Wait up, Arashi!"

"Woah!"

I tripped and fell.

"Gotcha! Hahaha…" My sister tapped on me.

When we reached home, dad called me.

"Arashi, mind going out with me later in the night?"

"Sure, dad."

I sat in his car, driving me to a field. I remembered his face clearly, he seem to have kept a lot of things to himself. He needs someone to talk to.

"Arashi, this is something important, and it shall be a secret between us."

"What is it?"

I would never believe his tales.

"My son, I was a killer, an assassin from a clan called 14 Blades. Each time I'm tasked to kill someone I don't know. There was once where I had to kill my friends. My hands are covered in blood, I can't forget or to forgive myself on what I have done."

His tears rolled out, he really had regretted of doing so.

"I left the clan and joined an organization to kill for a greater good, but I just can't forget the face of them in agony."

"Dad… Why you joined the clan in the first place?"

"I know it is hard to believe that your father is a killer. Your grandfather was in that clan and all children are part of the clan. I couldn't leave that clan, as those that left are marked as traitor and they will be killed along side with their family."

"What? Dad….. you left that clan, you mean….."

"Yes, if they found us, we will be killed. I'm sorry my son, to put you guys in danger, I don't beg for forgiveness."

"No, dad, I forgive you. You cried, because you still have the conscience within."

"Really? Now, Arashi, I have one request."

This is how I embarked a journey of 3 years.

"You shall be initiated as an assassin, I'll train you. This is to protect Mum and Yuki."

"Yes, I accept, I want to protect Mum and Yuki."

From that day onwards, we would jog everyday, with weights strapped on my limbs that are so heavy I couldn't run with them for long. But dad is merciless, forced me to run with them.

My limbs ached so bad that I can barely walked to school, but I pressed on, all is for mum and Yuki.

At night, I'm trained with hand-to-hand combat in dad's secret dojo. The monstrous training of constantly punching and kicking the punching bag, executing throws, bruised my body so bad. I sparred with dad, he did not even lighten his strength, a jab by his fist shattered my fist as well.

"Your enemies will not be merciful to a kid, you must taste the pain first hand to know your enemies."

This is what he told me. He broke my arms, legs and even with that I was forced to fight him. I was sent to hospital for countless times. With each excuses being an accident.

I fought with one hand, jogged 10 km with a pair of walking sticks. I for once hated him, but it was for the sake of my loved ones.

After my limbs were healed from the injuries. He forced me to walk on walls.

"Just run on the streets and then jump onto the wall and continue run as fast as you can."

Sounds easy enough for someone who have forced to run and sprint with nearly 20 kg of weights tied up for more than a year.

I broke my arm and a few ribs and I was forced to try it again and I succeed before passing out.

Knives can be thrown and they are deadly. I cut myself for countless times when throwing them.

One of the tricks was to catch the thrown blade. I was astonished that I could do so. I felt so relaxed and flexible when I'm running, everything stops when I run, the sensation is great and I felt unstoppable.

We sparred again, this time with a dummy knife and dad blindfolded. Despite I have the advantage of seeing him, before I can reach him, I was thrown on the floor with an arm broken.

I tried and tried, finally, I outsmarted him and "killed" him.

This time I'm being blindfolded, in just 1 second, I was "killed". With many times, I failed, each times lasted longer and longer, finally, with a disarm, I won.

Then the swords, which I was struggling, then I overcame them.

"Arashi, I'm proud of you. Now here's something for you."

Dad passed me the dark moon decorated switchblade and a sliver ring necklace.

"This is the same blade that is used by your grandfather and me. You are now the inheritor of this blade and the ring, you are now officially an assassin of the 14 Blades' arts."

I took the blade, accepting the mantle.

"I believe the 14 Blades are already closing in on us. There just be one day that they'll attack us. You must be ready to protect everyone."

"Yes, I'm ready."

He then showed me some things.

"This is where I hide the money, if anything happens, get the money and leave the town. Find Mr Woodman, he'll help you. And this is 14 Blades' headquarters, avoid going near there."

It was one night, we are awakened by a loud noise in our house. Yuki and I woke up.

"Dad! Where are you?"

I saw dad being stabbed by someone, the 14 Blades had attacked.

"Get out of here!" dad let out his last voice and collapsed on the floor along with mum.

"Mum! Dad!" Yuki screamed.

"Nee-san, hide there, get out when I fight them."

The men approached quickly.

I pinned the men and parried against their blades and metal baton. I saw Yuki leaving, but suddenly she screamed when another man spotted her and picked her up.

"YUKI!"

At a moment of distraction, I'm hit in the face by a metal baton. That man strangles Yuki and she died in front of me.

Before I can recover, I was hit by the baton again. The man hit me again and again, I could feel that my skull had cracked. I wouldn't forget what they did to everyone.

"You bastards! I'll have my revenge for killing my family as a ghost!" I whispered.

With another hit, my vision fade into darkness.

I woke up in full moon, my head pains no more.

"Am I in heaven?"

I can feel the grass beneath me. I woke up and realized I'm wearing a black suit, with skull fiend marks on my chests, my shoulders and on my fingerless gloves.

"I'm not dead?"

I sat up and saw our grave markers. To my horror, Yuki is beside me, wearing a blue-white dress with knight mark on her shoulders and on the long gloves, she's still alive.

"Nee-san, Nee-san! Wake up!"

"Ummm…. Arashi!"

"Greetings, Aokaze Yuki and Arashi."

We two see a man in dark.

"Who are you? What have happened?" I asked.

"Me? I'm Phantom. You two are brought back to life because it is your parent's death wish."

"You mean, our graves are empty?" Yuki asked

"Yes, you two are already listed as a dead person. Your funeral had taken place."

"You two will be granted powers and to become a spirit."

"What? What is a spirit?" I asked

"They are beings that caused the spacequakes, but nobody knows about the truth. Some came from alternate dimension and some are just like you two, human turned spirits."

I was stunned, how can that be possible? Spacequakes are caused by being called spirits?

"Why? Why us?" Yuki asked

"Because of your death wish. Aokaze Yuki, your death wish is to reverse the incident. You are granted the angel Abaddon. And Aokaze Arashi, your death wish is to avenge your family. You are granted the fallen angel Nevermore."

"As a price to pay, one will lose his or her sanity, to gain that sanity back, one will have to venture back to death with a chance of not being back alive."

"What?"

"Find a man with multiple divine souls, he is your salvation."

"What are you talking about?" I asked

"I can't say it, you'll figure it out yourself. Now, you two should get together and plan on how to solve your situation."

Phantom vanished into thin air, I brought Yuki to the dojo and we stayed at the dojo. I told her everything.

"Sorry, I'm at fault, Nee-san"

"Is okay, as long as we are not alone."

We slept at the dojo, but I left her alone with the map of the killer's HQ.

I arrived at the HQ, 13 people are at there, at a small hut. All of them were in the house that night.

I appeared in front of them.

"It's Aokaze Nanaya's son! Isn't him dead?"

"Doesn't matter, we'll kill him. Protect the master."

I understand now why they are called the 14 Blades. Each person carries a specially crafted knives or sword.

There is a voice calling me, it seems that I know my powers.

"Nevermore!" I shouted.

My shadow distorts then a sword is formed. With one hand I use the shadow blade and the other using the switchblade.

We clashed, I suddenly see lines and points.

"Cut those lines, pierce those blue points, absorb their souls, pierce the red points to kill them along with the soul."

Instinctively I followed the voice. The men have similar arts like mine. But with a gesture from me, the shadow on the ground burst into a blue black flame, a man is knocked out, but more blue points are formed. I pierce the point, the man's shadow is separated from his body and entered my shadow.

"More! More!"

I followed that voice's hunger for souls. This time, I saw lines on the shadow and blue lines on the body. A man rushed towards me with his sword, I just simply trace the lines on the sword, they broke into pieces. Then I slice the body along the line, he did not bleed, but a portion of his shadow is absorbed. He collapsed on the ground.

I felt more strengthen and I'm attuned with my powers. The rest of them rush towards me.

"Nevermore, SHADOW REQUIEM!"

The fallen angel surrounded me, cloaked me to be exact. It unleashes the souls of those that I killed along with many other souls. It blasted them around me. These savaged souls tears the men's flesh, all those who killed family are not spared with their souls being absorbed.

The master is in the hut. I entered and he saw me and he is scared. I grabbed him in the neck.

"Aren't you already dead?"

"Yes I am, but vengeance brought me back! Why kill us?"

"Hahahahahaha... you still in your dream aren't you?" the master pleaded

"ARASHI!" It was Yuki.

"Don't do it! You killed 13 people already!"

Just as I was about to release the master and let him go. A pain so strong struck my head.

"ARGGGGHHHHH….."

I couldn't control my body, my shadow formed a demonic arm and plunged into the master's shadow and ripped it out.

"How dare you not obey? I granted the power of darkness to you! Fine, you shall be my host! I'll destroy the world with you being my scapegoat!"

"NOOOOOOOOOOOOOOOOOOOO…"

"I shall get rid of the salvation as well..."

"GET OUTTA MY HEAD!"

Suddenly in his vision, he saw someone looked like him, covered in blood. But he couldn't tell who is it.

Arashi woke up from his bed

"It is a nightmare… and it is that person again." he whispered.

Arashi grabs his switchblade. He remembers the feeling back then, it is a horrific one. The encounter with the dark voice. He remembered his date with Kaguya, the orange coloured hair girl he loves today.

"I'm sorry, Kaguya. As much as I hate it, I have to do it…."
