In ancient times, there was a devil called the Devil. Although he is greatly feared by the surrounding community, but there are people who often ask for his help because they say he has black magic powers.
One day, a woman comes to ask for help from him, who he thinks can help him with something. And he did not realize that his mistake in asking for the help of the Devil, would bring his kingdom to ruin in the blink of an eye.
"Hey Devil, I came here to ask for your help."
The woman said looking into his eyes, who was sitting on a large chair while kneeling on the ground, putting her hands together as she felt very nervous.
"Hahaha, of course. But as you know, I will take the most valuable thing in your life as payment."
The Devil replied with a haughty smile as he looked at the woman in front of him while hiding in the darkness.
With that, the woman agreed to the deal while nodding without thinking of anything else.
She just wants to be the prettiest in her village as she is often ostracized by society because of her ugly face.
He could not feel that he was going to give up something that could destroy the country of his kingdom.
"So ... what do you want? What have you dreamed of all your life? Abundant wealth? Magical power?"
The Devil asked, even though he already knew what kind of desire he intended even though he only saw her appearance.
"I want to be the prettiest in my village, so everyone won't make fun of me anymore for being the ugliest. I'm tired of them, so I want to change fortunes and my kids won't be ashamed of me."
She reacted with the excitement flowing in her body as she wondered how they would react if they saw the change.
The Devil nodded and grinned, knowing that this would benefit him as well.
He raised his hand as black smoke came out of his hand, he headed towards the woman standing in front of him, waiting for his movement.
In the blink of an eye, the woman's face looked young and very beautiful, so that the devil was shocked to see her too.
Then he got an idea and walked towards her with a smile.
"Do you want to stay by my side? I promise I'll give you everything you want if you agree."
"O devil, I came here with only one wish, and have promised that I will give you something important in my life."
The Devil nodded, understanding that his invitation was rejected outright, and returned to his throne while staring at her by placing his hand on his chin.
"All right, I respect your decision."
Then she returned home, while the whole village looked at her with disbelief at her change.
When she got home, she opened the door and her eyes widened looking for her children, feeling very excited to show the change in herself.
"Children? Where are you? I'm back home. Look at my face! I'm so beautiful!"
She said while looking for her 7 children. But she was silent when she did not see her children appear in front of her or run towards her. She felt strange about the state of the house being very quiet.
She searched for them all over the house, and found that they were not there.
They would never left the house if she was not at home, in fact they did not want to go out and receive ridicule from the villagers about their mother.
They love her so much that they don't care baout how she looks like.
She sat on the floor thinking where are her children? Where have they gone?
Then, she remembered his agreement with the Devil.
She really didn't think that the Devil would take her children as a reward, so she regretted it as he roared alone in the dark house.
Not for long after that...
The Devil uses this opportunity to take over all the kingdoms by using the 7 boys, attacking the kingdom inhabited by the woman herself, and the kingdom he has wanted to conquer for all this time.
He gave each of them the power of darkness and turned them into an evil by mastering their minds, so that they forgot their origin.
He controls them with the power of black magic, which is able to make them hear his every words.
After a big fight, they managed to control the kingdoms of KRYSTAL, PEARL, EMERALD, RUBY, VICTORIA, and the most powerful kingdom was the kingdom of DIAMOND.
The DIAMOND Kingdom is the most powerful Kingdom among all the provinces. The kingdom became strong because it had a very strong king. His power is like 7 man with a super power.
Unfortunately, he was being defeated by SATAN and the 7 boys. Before the King was defeated ...
"Got a word before you die?"
SATAN asked arrogantly as his feet stepped on his body, with a cynical smile.
"I promise, one day there will be someone who can defeat you all and take back this kingdom."
Those were the last words of the Diamond King before he breathed his last.
And with that historic day, the Devil officially became the King of all kingdoms and was dubbed as Han Jae Min. He administered all the kingdoms together with the seven boys.
Torturing the people who used to served the previous King, and to whom stayed loyal to him, making the whole kingdom like a hell.
However, they have drawbacks.
Jae Min is very scared of someone who has a lot of power like the King of Diamonds. But he believes that such people no longer exist. He thought only the Diamond King had that power.
He does not know about the reality of such people still EXIST. And he wouldn't have thought it was just a little girl who was coming to find her mother.
So... what will happen, if they all meet the DIAMOND PRINCESS?
