Long ago there was a loving family of three that had incredible abilities that one could not predict. A perfect couple with a lovely young boy at the age of three were holding the blood of their ancestors that used to be the most powerful Tenma's of the demon relm. The history was irresistible and brutal, but loyal. The name of the vampire rulers are the 'Kuroko's'.

The Kuroko's have all the respect opon both weak and powerful and had more freedom. Living in the devil side of Japan that could be transported by portal was quite calm, knowing that the humans and immortals are safe between each other. In the immortal world was like any other normal land. The nonhumans have cozy homes, restaurants, shops, schools, all that the normal world has. Except that the citizens aren't that normal, for they have their own little power. There's witches, wizards, wolves, goblins, talking animals, half human and animal. And of course there are the only Tenma's, the rulers of the relm. The Kuroko's hold all powers that Satan could perform. If the curse lands on the wrong hand, for the world would be a catastrophe.

The citizens worship the rulers with loyalty for their compassion and power. The Kuroko's has ruled the kingdom for more than 10 million years, the next in the royal chart shall take over the next generation. Female or male, either one could take over unless they have the will and control over their abilities.

First off is the king of the Teiko Kingdom, Tetsum Kuroko. The 100th king of Teiko, age 1067. Has golden eyes and black hair. He may sound old but has the physical trait of a 20 year old. Has a passion in reading and have an outgoing personality, but when it comes to work and family, he could be strict and protective.

By his side is his shy and quiet queen, Tetsuma Kuroko. Age 1058 who has sky blue hair and ocean eyes which is one of the reasons why Tetsum loves her. She could be scary when one threatens her loved ones. Overall, she has a kind and royal heart towards her kingdom.

Inbetween the couple is their three year old boy but in immortal age is 103. Kuroko Tetsuya, the next to rule after his father. Has blue hair with a left golden eye and a blue one on the right. He has a passion in novels and is mainly quiet with his deadpan face. He has a 'Yendere' side if he has enemies among his parents. His idol is his father for his leadership and for his mother is her warm heart.

The castel is located in the middle of the kingdom. It was shaded in black and white which made it more traditional for those colors are the main colors in hell.

As you than enter, you shall sence a warm welcome of the Sakura Tree smell that was sent from around the castle. Those who trespass shall have a hell some curse that could rather lead to death or complete misery. In order from that to not happen is to be invited by one of the loyal owners. There would be souls that gaurd the castle from danger, and beautiful house maids that serve the house.

One secret that the king and queen holds is the presence of their only son, in order for him to be protected. If the evil knows contact of the son, he shall be the prey to their next feast. Years back, the previous king informed that he had a daughter and was soon devoured by the enemies. Although he has brought back revenge, but is a life leason that to hold your possession in your embrace for life.

Kuroko was home schooled and was still confused on why he couldn't go to a regular school. No matter how his mother or father explain, not even a light bulb would flicker in his head. Kuroko wasn't completely lonely for his parents created a spirit wolf to stay by his side for company. Kuroko would stay in the library and in the night time, he would lay down on the roof to spot silver shooting stars.

Present Time

Kuroko is now 150 years old, which means he turns into a senior. In high school years, you have to spend 5 years in school in order to graduate in the demon relm. They teach the basics in magic and transform into a specific person or thing. For Kuroko, he has learned all the high standards but will still be studying in order to gain more of his strength.

On a normal slightly cloudy day, Kuroko was reading his novel on top of the roof with Nigou; his spirit wolf lying down on his masters lap. A few minutes has past until a maid popped out of no where.

"Kuroko~Sama, the king would like you to visit him in his office." The beautiful maid bowed as she than disappeared back to her duties. Kuroko sighed as he marked his book and walked to his destination while Nigou was walking besides him.

"I wonder what it's about Tet~chan." Nigou spoke up.

"Me too." Kuroko responded as the maid opened the kings office door for him. As the door closed behind him, his mother was leaning on the desk reading, as his father was sitting on his chair filling in some paper work. As Tetsuya fake coughed, both older Kuroko's looked up and spotted Tetsuya with a small smile.

"Hello son, please sit." Tetsum greeted while Tetsuma sat next to Tetsuya.

"You wanted to meet me, father?" Tetsuya asked as he took a seat on the black singal chair.

"Yes, your mother and I have some great news that includes you." Tetsum smiled as he placed his pen down in place.

"Which is?" Tetsuya asked with confusion.

"Next week on Monday sharp, you shall attend a private school that happens to be the most popular school in the kingdom." Tetsum clapped his hands together while Tetsuya's eyes widen with surprise.

"Next week?" Tetsuya's jaw dropped a bit while both older Kuroko's chuckled a bit.

"Yes sweetheart. As we remembered, you wish to go to a real school. So your father and I thought about it for a while and finally gave in. We shall set you in the upper class and when it stricks 8:00pm, you will have your real class to teach you the things you yet don't know." Tetsum smiled as she reached for her son's hand.

"I... Don't know what to say." Tetsuya stuttered until Tetsum walked up to Tetsuya and held his right shoulder.

"We wish for our son to be happy and have what he wants. Kuroko Tetsuya is the son of the king of Tekio." Tetsum giggled while Tetsuya gave in for a hug.

"Thank you mother, Father." Kuroko smiled deeply as their parents kissed his forehead and smiled with courage.

"You're welcome dear Tetsuya, also...." Tetsum stopped for a moment as they disconnected from the hug.

"Your name will be Tetsuya Kuro so people won't know your true identity. You do know why right son?" Tetsuma finished the sentence.

"I understand mother, and thank you again." Tetsuya said while his eyes sparkled with joy.

"Good, your uniform will be ready on Sunday. Now go ahead and practice on your training for an hour and the maids will make your favorite milkshake." Tetsum patted Tetsuya's head a bit.

"Yes father." Tetsuya obeyed and changed into his training uniform.
