In the foundation of the world, there are three elements: the clam, the rainbow and the ocean. They are the source of life and growth, and more importantly, they are the balance of the Earth's life force.
But there are times when the balance is destroyed, because for all of their strengths they have weaknesses than no one else can fully understand, and if they fall- the worlds fall with them.
The clam goes on and on, passing its form down the generations; wherever he looks, be it up, down or to the side, he is surrounded by peers and partners who are going through something that, if not the same, is still similar enough to support them.
Tsunayoshi had been thrown into a position too big for him; but soon he had found friends who believed in him, who would support him no matter what and who he could always relay on. And when things got hopeless and scary, there was always a comforting weight on his hand, an old heirloom and a memory of his ancestors. And with them, he was truly unstoppable.
The rainbow appears from time to time, never stopping for long in one place; she is observed with awe and wonder, respected and loved by all. She is free to contact with the clam and the ocean as she pleases.
Uni was young, though fate had already dealt her a bad hand. Even so, she was the heart of I Prescelti Sette; many people sought to consult her, even if they doubled or even tripled her age, and she had a Famiglia to take care of. She was admired and knew that there were people who needed her; and that knowledge helped her move forward.
The ocean knows no bounds. He is lonely, even while surrounded by people. The clam and the rainbow do not seem to be enough to justify its vastness, their contact is fleeting and no matter where he looks, the sea is the only one who is an independent entity- no matter where he is, the only constant in his life is himself.
Byakuran had had an unremarkable life until the day he woke to his power and saw the worlds for the first time, until everything he thought he knew was destroyed in an instant. He was forced to see, over and over, millions of reflections of himself. Some were successful, some were lost in their bitterness, a few were too naïve and most were unsatisfied. But he might have been able to deal with just that.
Yet his closest friends in one world had betrayed him in another; the ones he had hated before, now deserved pity. The ones he had feared, now he had the knowledge to destroy them. There was nothing constant, except war, death. And himself. How could he be sure of his own identity when it was subjected to so many other variables? How could he be sure that, in this newfound universe only he could see, "he" still existed?
Did anyone truly exist?
In its mounting despair, the ocean retreated into itself; he became blind to his responsibilities and used his mighty tides to destroy and dominate in his effort to make sense of the world, growing more and more desperate the more seas he conquered and bent to his will. He tricked the rainbow and trapped her in her own reflection and he endeavored to destroy the clams that time and time again tried to oppose him; but the clams lived in the depths of the seas, and surrounded and outnumbered, they would never win on their own. His search was coming to an end, but he was never satisfied.
It wouldn't be until much later (much, much later after he was defeated in the last free sea and the multicolored light had slipped from between his fingers) that he realized there was one more constant he had overlooked before. They may be changing and short-lived, but they were always near. A friend and a rival, the rainbow and the clam. No matter who embodied them, they would be always by his side, because they were equals, they were one-and-three; they were the tri-ni-sette.
The ocean could look at its own vastness and realize… he was not alone.
The balance was restored.
