Tell me, reader, can you put a name to something for me? To an opposite but connected, self-perpetuating cycle? To the harmony of black and white together, never to be separated?

Black, dark as coal, black, the colour used throughout human history to describe suffering, pain, loneliness. Black, the colour of the underworld in ancient Greek and Egyptian culture.

Black, the colour of mourning in the Roman Empire and consequently much of the european realm. Evil, witches, magic. The black tulip, the aircraft used to repatriate the bodies of deceased soldiers to their poor, unfortunate mothers, doomed by black.

Black has been surrounded by death since the very start. Human beings were never fond of the dark—it made you nervous, skittish. It made your breath catch, your heart pound.

So from darkness humans ran and turned to light. White: Purity and perfection. White was the colour of a blank slate you could start anew on, wiping away all your past sins. White was the true balance of all colours, representing harmony and clarity.

White could catch your eye immediately. White had the heart of a saint.

I'll save you the trouble, dear reader. I'll put in a name for you—Yin and Yang. A well known concept, originating in chinese philosophy. Bad in good and good in bad— that was what white and black meant to them.

When the Ying is the strongest, it contains Yang. When the Yang is the strongest, it contains Ying. When it came together in a mixture, but still distinctly it's own individual: it created something worth seeing.

Compare it to him. Compare it to completely jet black hair, with only a stripe of white. To inviting, soft brown eyes. To him, who always had a hand held out. Usually accompanied by his favourite colour: orange. The hero.

And now the hero's counterpart, his reverse: completely stark white hair, leaving only a strip of coal black. Prominent bloody eyes, made even more prominent by the drying, darkening red that stained him everywhere. Riddled with evil and death.

Born from the same womb, with the same bloodline... but opposites in every aspect, yet connected as twins.

They come together again after years of isolation: forming a spectacle.
