Prologue

"KEITA!" A woman with long ginger brown color hair and red eyes screamed. Standing by her side was a man with short dark blue hair and ocean blue colored eyes, his expression horrified at what was in front of them. In a glass container tube filled with blue liquid in front of the woman and man was a small child no older than one or two years old. The child had really short ginger brown hair like the woman's; however the child's eyes were closed.

"Kouestu-san, what is the meaning of this? What are you doing to our youngest son?" The man with dark blue hair yelled at a man who was in his 60's. Before the man could reply to the blue haired man, all of a sudden the three of them hear a siren alarm. Next thing they knew was the sounds of explosions and inhuman growls.

"Warning, Warning, Shadows have escape! I repeat Shadows hav-AAAAHHHH!" All three of them could hear a blood curdling scream from the speakers. When the scream died down, they could hear several of the inhuman growls from the speakers. "Shit, Akane try and free Keita!" The dark blue haired man said and takes out a black tube that was shaped as a tampon except a little bit bigger with length.

"What about you?" the ginger brown haired woman named Akane asked before pulling out a silver Colt Anaconda magnum out of the gun holster that was on her waist. On the opposite of her waist was a katana, the handle of the katana was a crimson color and the sheath was also a crimson color except a darker crimson.

"Don't worry about me, just save Keita and I'll keep them at bay!" He said and went pass the old man who had a shock expression. Akane cursed under her breath at the old man and aimed her gun at the glass tube.

When she got a good spot to shot at without hitting the child named Keita, she aims the magnum at the glass tube container and pushes the trigger. The bullet flies out of the gun and hits the glass; when the bullet came into contact with the glass, the glass shatters and the weird blue liquid leaks out of it. "Keita!" Akane yells and catches the small child.

When the child fell into her arms, the child opens his eyes to reveal beautiful ocean blue color eyes like the man that left the room. Before Akane could leave the room with her son in hand, she suddenly feels pain in her chest. She let out a grasped and fell to the floor. She then looks down at her chest to see blood…and a hand with claws covered in her blood.

Akane slowly turns her head to see what was behind her. Her eyes widened when she sees who the hand belonged to. Behind her was a woman with long jet black hair, scarlet red color eyes, pale skin, and wings, the left was a midnight black and the right one pure white. The woman was also wearing a black kimono with a light blue obi around her waist. Akane growled at the woman, "Why are you here…Shi no Tenshi..?"(1) Akane asked and begins to cough out blood.

"…" The woman didn't answer, but instead her eyes were on the child in Akane's arms. Akane notices the woman was looking at her child and she growls at the black haired woman. "What do you…want..?" Akane asks and coughs out more blood.

The black haired woman turns her attention to Akane. "What I want onna (2), is at you wish to protect your son and daughter no matter what…right?" She asked and Akane looks at her.

"And if I wish for that…what would you do..?" Akane asked as she could feel a little bit of her life force slipping away.

"These fools in this place have given my heart to your son," the black haired woman looks at the child, "and he is now my chosen one." The woman said and kneels down to face Akane.

"But isn't that your hand in my chest…that is bleeding..?" Akane said and looks at the hand.

"No, unfortunately it is one of the 'Shadows' that did it…" The black haired woman said.

"So…I'm going to die..?" Akane asked and more of her life force was slipping away.

"Hai,"(3) the woman replied.

"Then…promise me that…you will try to protect him and his big sister!" Akane said and coughed out more blood.

"I will…" The woman said quietly.

"Arigatou gozaimasu…" (4) Akane whispered quietly and the light in her red eyes faded away and her body fell to the floor with a thud.

"AKANE!" Someone yelled and the scene went black.

Keita immediately opened his eyes and let out a grasp and stands straight up. His whole body was covered in cold sweat and his heart beating fast in his chest. "W-What kind of dream was that...?" he muttered to himself and ran a hand through his hair. Lately for the past week, he had been having dreams that involved two women and a man with dark blue hair.

He didn't know who the women were, but the man with dark blue hair he did know. The man was his father, Ito Kaito (5). Keita remembers that his father loved their mother, but from what he could remember was that their mother was killed. He was only one or two years old at the time, but he couldn't remember what she looked like. All he could remember of her was that she had long ginger brown hair.

He lets out a sigh and gets out of his bed. Keita slowly walks towards his room balcony and looks at the rising sun. He closes his eyes and lets the wind blow in his face. 'I wish I could stay here until a graduate…' he thought and opens his eyes to look at the sun.

However, unknown to Keita and the people around him; fate had a card up her sleeves, a card that will not only change Keita's destiny, but also his potential.
