The Beginning

The black haired demon king stood tall, his robes wrapped around him, as he leaned against one of the pillars in a large room. He hadn't let Erika touch this room; it still had the original carvings, engraved in the wall, down to the small cot, that he had once slept in. The room wasn't used often, it was the demon king's birthing chamber. Ignoring everything around him, his ocean blue eyes were fixated on the screaming woman in front of him.

The woman was a succubus, named Vorona. Her long blond hair splayed around the room as her scream echoed throughout the chamber. Nine months he had kept her in his palace, nine months since a new friend had died and the future demon king had vanished. Mikado stared at her blankly, not letting his hatred show in his eyes. He had cared deeply for Shizuo, finally glad Izaya had found a mate. It was a harsh world and the fake blond hadn't seen his death coming.

His now darkened gaze, dropped to the squealing fortune teller, standing by his side. She had a huge smile across her face. Because fate worked in strange ways, even though he had lost the two he cared about, his mate's reincarnation was currently being brought into the world. Every time Kida had been born, it was as a human, less than a century and he was gone again. This time, his mate was being born as a half demon. He let the grin tug at his lips. If he had let Vorona give birth in the human world, the human side would be dominant.

This was why he chose the birthing chamber. The carvings and engravings giving power to the newborns, making them more demon than human. Mikado turned his attention, back to a different cry that filled the room. Stepping forward he ignored the exhausted woman and the doctors, taking the small bundle in his arms. The baby slept soundly in his arms; he gazed down at the soft features, his eyes becoming damp, as he remembered the last time he had held him. He took the tiny fingers that formed an unbreakable grip around his finger. His chest swelled as reality hit him, it was really happening. He had his soul mate back.

Reluctantly handing the child to Erika, he gently picked up the second one, the one who had broken the cycle, the impossible child, who shouldn't have been born for at least half a century. He could sense the power radiating from the new born, this one would be difficult to handle. Dark caramel eyes, gazed up at him, the wailing still echoing around the chamber. "I'm sorry, little one. He's not here." If anything the child cried harder. Even so, Mikado stroked his face with the side of his finger, trying to calm him. "Welcome back."

He smiled as the baby blinked, his gaze dropping the woman panting in exhaustion, but still demanding to hold her children. He was sure the child's eyes narrowed glaring at the woman. Caramel eyes closed, finally joining his twin brother in slumber. "Karisawa, have you found anything?" He left Vorona wailing for her babies, as he left the chamber, Erika at his side. "No, Mikado-sama. I can't see him."

The demon king sighed, somehow knowing the sleeping baby was listening to every word he said. "I can see, they will find each other. They are the future of the demon realm." Mikado said nothing, he knew the moment the child was born, he was special, the power he could feel, rivalled his own. He was holding the new demon king. No that wasn't right, today had been the birth of two demon queens. His own and the one currently dreaming of his lost mate.

"Mikado-sama, should I notify the demon realm?" The demon king looked down at the two sleeping babies. "No, not yet. Lets leave it." He didn't want his mate to be in danger this soon. "I'll arrange protection for the two of them." Now that they had demon blood, they could be with their mates for several lifetimes. He closed his eyes briefly, realizing he wouldn't have to see his mate die, so prematurely.

3 years later

Mikado groaned laying back in his throne. Raising a human, he could handle, but the two Halflings were nightmares. Both of them were quickly grasping their powers, before either could talk or crawl, they had thrown one of their building blocks through the marble wall, the two blonds had looked up at him, innocence in their eyes. Rubbing a hand through his hair, he held out his palm, fixing the damage. Most of their toys were either embedded in the walls or lying scattered outside the palace walls.

Kida was the quieter one out of the two, as soon as he picked him up, he would be asleep. The other child would not fall asleep on his own, Mikado had discovered the only way he would settle was to place him in the pitch black cot, with blood red sheets, the young boy would immediately stop crying, sniffing at the sheets, wrapping them around him and smiling as he closed his eyes.

The two young blonds quickly grasped their powers, Mikado sighed, hearing a loud crash, and the scream of one of his servants. Of everything the twins had discovered, their wings were the worst. Seconds later the two young blonds flew into the room, Kida looking away guilty. The demon king shook his head, holding out his hand. The two twins slowly came down, their tiny feet touching the ground. As soon as he let go, the two were gone.

The one time Mikado had agreed to take them outside the palace, everything had gone wrong. To hide their marks, he slipped mittens onto their tiny hands. The twins were excited, running around, but always staying close. The younger of the two froze, looking around him. Mikado crouched down, seeing the boy cry. "What's wrong?" He reached out to calm him, blinking as the child vanished in front of him.

Mikado blinked seeing the boy disappear into thin air, Kida immediately stopped crying. "Mikado-sama! Mikado-sama!" He turned hearing the fortune teller, run towards her as fast as she could. "He knows how to teleport." She crouched over, hands on her knees as she panted. "I know, Karisawa. He's gone." Running a hand through his hair, he reached into his robes, taking out his phone. "Karisawa, I need you to go to the human realm." The fortune teller beamed. "I get to see Dotachin." In the mean time, he hoped the young boy stayed out of trouble.
