A/N: This fic, we, and yes, WE made it, me and a friend of mine made this fic. I can't speak English very well, so I asked her help to type this in English and because I don't know how to say this all in a good English, so she typed all of the story (I'm so mean T_T), I gave her the ideas of this story and she wrote it with her style. I just re-editing this, adding some lines, some dialogues (in the next chapter, this one does not have any dialogues), and fix somethings… and upload this. I really want to thank her because if she's not here, this story would never be realized. You can say that this is a collab. or something? Okay I don't care what you call it as long as this thing can be read, please enjoy~
Additional Note: Please, no flame! T_T
Prologue

There are two kingdoms in a place unknown to Earthlings. The first kingdom is in a dark place in the core of Earth. The buildings are old 16th century style and the roads the same. Most of the buildings are painted in a bright red in order to make it a bit lighter. The people living there have wings as dark as the night sky without the shine of the stars and the moon. They are known as "demons" or "devils", suitable it now is. It didn't used to be that way before. That was before the wicked Kings and Queens got power. Now, one cannot trust these people, because wicked they also have become.
Most of these people are soldiers trained to kill and show no mercy. They are forced to become this whether they like it or not. Slaves take care of the towns, yet they are looked down upon. The women, just as ruthless as the men. The children learning to become the same. A society where no one is free, yet no one cares. This kingdom is called the Kingdom of Hell.
To other kingdom is in a light place above the clouds. The buildings are the same as those of Greece and, by the roads, wonderful palm trees grow. The buildings and roads are all white. Most of them have plants growing up on their sides. The people living there have wings as white as the clouds they are above. They are known as "angels", their wings surely are angelic. Unlike the Kingdom of Hell, this kingdom has had more good rulers than bad. Their current ruler not being the best, but still very close. These people aren't all good, yet there are only a handful bad ones. There are no slaves, that being prohibited. Being a stabilized and organized civilization, these people have it well and live in what you'd call an utopia. This kingdom is known as the Kingdom of Heaven.
650 human years ago, a war began between these two kingdoms. It was a cold, long war. The merciless soldiers of Hell attacked the Kingdom of Heaven. The Kingdom of Hell is an offensive force unlike the Kingdom of Heaven which was a defensive one. The soldiers of Hell had armor and shields as dark as their wings, whilst their uniform was crimson red. Their main weapons were swords and scythes. They also had chariots along with a few archers. Their flaw is their lack in defense because of only concentrating of offense. However, strong, quick, trained for war, and many, the warriors of Hell attacked.
The Kingdom of Heaven is, as said, a defensive force. Their armor shining silver, as shields golden as the bright sun above them, and uniform as blue as the Earth's sky after rainfall. The main weapons they used were spears along with bows and arrows. They have a long strong wall around their border with watchers and archers in the high towers connected to the wall. Within that wall, is another wall. This wall is their last protection against invaders. Along that wall are high-class special trained defensive mages and archers. But, to get to that wall, one must go through a jungle filled with dangers as well as special trained guerilla soldiers. Yes, Heaven's defense is indeed amazing, however, it prevents them from expanding their kingdom. Also, their offensive strength is way below that of Hell's.
As the war developed, Hell's warriors broke through the first wall and entered the jungle in thousands. Heaven's guerillas kept them busy while taking them out slowly. The special trained mages of Heaven protected the border to the kingdom whilst the war was becoming worse and worse. Hell's resources seemed unlimited and Heaven's defense seemed to be getting weaker. However, after 450 human years of war, it was clear that Hell could not win. The guerillas forced the now small army back to Hell. All in all took them 50 human years to make them all retreat and make sure no one was left. The bodies were disposed of and the re-building of the walls began. People from both sides mourned the lost ones. The kingdom of Hell had to work a lot to regain what they had lost, Heaven had to do the same.
Shortly after the victory, the King of Heaven was blessed with a gift, or should I say two. He received two children, one boy and one girl, twins. The boy was named Len whilst the girl was named Rin. Rin, being the firstborn, got the honor of being her father's successor. Both of them got a necklace each. Rin, being the successor, got the Treble Clef, whilst Len got the Bass Clef. The necklaces were dark as ashes, but had a shine that was as pure white as the first clouds after a rainy day. Both of the twins came to treasure their necklaces just as much as their relationship as twins.

Meanwhile, in the kingdom located in the underworld, or as we say, the Kingdom of Hell, they were planning something unpleasant, the bitter-sweet revenge for their fallen ones...
