In this world, there exists a balance.

This balance consists of light and darkness. Light embodies all things good; such as an innocent life, a warm breeze, a smile. Darkness embodies the opposite; such as a wicked storm, a betrayed heart, unhinged psychosis.

The fate of all living beings depends on this balance staying in check. Every individual life takes a path in the spectrum between good and bad. Once someone is born, their path has already been chosen for them.

Rarely, a perfect combination of light and dark is created. A person who is neither good nor evil.

When such a 'being' is created, it is split into two. Soulmates, if you will. Two souls who balance one another and keep the weights from tipping too far into one realm or the next. Their red threads of destiny and fate are entwined, interwoven into one another, forever tied with a bond unable to be broken. Their existences are foretold and blessed with good fortune.

However…

There is always the chance that the balance will be upset. Though it is a very small chance, such an event would cause great catastrophe if the balance tilts too far in the wrong direction. Should it fall too deeply into darkness, tragedy will prevail. This spells despair and pain for the 'soulmates'. If this should happen, their story will forever be altered, beginning a never-ending cycle of pain and sorrow.

Their souls will transcend through time, trying to restore what has been destroyed- yet they will never achieve the fabled 'happy ending' that is desired…

...Unless the balance is restored, no matter the cost.

A displeased expression resided on the man's face, his thin fingers tapping angrily on the arm of his chair.

"Even after all our effort, you are saying that they were reborn?"

The pawn he had angrily gazed upon shrank beneath the heavy weight of such disgust and disappointment. They knelt before him in humble submission, bowing deeply, too afraid to raise their head. In his presence, their small existence crumbled under his weighted aura.

"Yes, Master. The soulmates have once again been brought into the world."

The man's fist slammed down angrily into the thickly cushioned chair, making his quiet servant tremble with fear. Anyone could feel the vibes of pure outrage reverberating off the man's cold demeanor.

Growling, he had risen, his cloak- the embodiment of a sea of stars, yet able to show any man what true emptiness was- swishing about his tall figure. His pale fingers ran through his hanging silver locks, and his brilliant red eyes shone with unreleased anger. The man could be considered a fine candidate for a model. He didn't have a single blemish, scratch, or flaw on his entire frame. He stood with regal authority, not one hair out of place, not a single thread undone in his fine attire. His skin was beautifully translucent, his face handsome and defined. However, this was lessened by the cruel twist in his features that turned his expression from angelic to demonic.

His full lips curl into a smirk, and a low chuckle echoed through the wide room. He stood tall, and though his gaze was turned toward the ceiling, he was seeing past it to something different, something sinister and dark.

"...How long will we continue this dance?" he said to no one in particular, paying no mind to the servant fallen silent mere feet away. "Just how long will we be placed within this eternal struggle…?"

Centuries. Millenniums. For the entirety of time itself, we have been part of this unseen war. You, fate's child and destiny's lover, and I… the true form of darkness. I thought that perhaps we had reached the end of our tragic story of rebirth and defeat, and yet still you return to taunt me.

Not this time. I will not allow this cycle to continue any longer. I am finished playing games that the rules have long been obediently followed. Now, I will use my own rules, and bring this game to its final conclusion.

You, the soulmates who have kept me from my triumph, will stand between it and I no longer.

I will tip the scales in my favor and break every unspoken rule in order to win this ongoing battle. The darkness will snuff out your feeble light for the last time.

And as for you…

I will make your suffering everlasting.

A/N: Hey guys, guess what? I'm actually planning out a multi-chapter fic! *gasps all around* That's right! Something that *isn't* a oneshot!

This was beta'd by the wonderful Piriluk, who is very kind and helpful :3

This story right here has been eating me alive for the last couple of weeks, and I had to write it! Now, I want you all to know- this will differ greatly than most my other stories. This has a tragedy tag for a reason- I'm going to do my best to rip your hearts out again- and again- and again. There will be no mercy for you poor Lenrin fans. I know- I have no mercy even on myself for this one. Writing the first chapter was literally one of the most painful things I've ever done, haha.

This story's ending is unclear- I won't let you know beforehand if it's ending or not in a certain arc. Whether Len and Rin have their happy ending, or the story they are part of is doomed to tragedy again- you'll only know once you read it. I don't know know how long this will be, but it all depends on whether I choose to allow them to be happy, or torn apart by fate once again.

Each arc will basically be a different song they are 'reborn' into, alright? Warnings for blood, swearing, suggestive situations, and this is going to be noncest and twincest. Letting you know now, alright?

I'm going to start updating once I've gotten more chapters written- but for now, have a small piece of what I have planned. :3

I hope to see you all when the first chapter arrives. Be prepared.

Read on~!

~Disclaimer: I own a cloak made of a star-filled void, but not Len, Rin, or any other Vocaloid fanmade or otherwise. Sadly ;_;
