Let's talk about yin and yang. 

An amazingly simple concept in and of it's self. 

Male and Female. Good and Evil. Black and White. Chaos and Order. Love and Hate. Heads and Tails. 

two sides to every story.

two halves, completely opposite, and yet they cannot exist without each other. Remove one half and you are left with nothing.

two sides to every story and two halves on every coin.

Lest just say that this soul is a coin. On one side is a smiling girl, full of smiles and happiness. Flip the coin over and there's the same face. Only this one is older, more mature and is filled with a barely compressed hate.

It's rather interesting, really. 1 soul, two bodies. Identical, and yet at the same time opposite.

One of is the face of a girl that should be born 400 years in future from the point this story takes place. The other died 50 years ago. And yet both of them are currently walking around, trying to complete the same mission. May be through different means, but is its the same goal.

Old fashion coins were made of one solid complete metal. That's not true anymore. Now, under the stamped covering that distinguishes heads from tails is a core made of a completely different metal. For instance, under the copper covering of a modern American penny is a core of zinc.

Let's see what's in the inside of this 'coin'.

There's a second soul here, one that is made of halves as well. Half youkai, half nigen.

What a strange union that two such opposite breeds should love each other enough to produce offspring. Or at least stand each other for 15 minutes... 

But two halves do not necessarily make a whole. This is half breed is also on a mission. It parallels the goal on the soul on the outside of the 'coin', and yet it's goal is slightly different.

This one wants to be whole.

Guess two halves don't make a whole after all. Well, that blows my yin and yang theory....

But does it?

Male and female. Good and Evil. Black and White. Chaos and Order. Love and Hate. Heads and Tails. 

All souls are supposedly searching for it's missing half, only then will it be complete.

If you remove the zinc core from a copper penny, the copper shell is very weak and brittle. It collapses upon itself. The zinc core by it's self is fairly strong, but has a habit of getting scratched and dinged. It's easy to mar the surface.

But if you keep the copper and zinc together, you've got a strong coin that will last much longer than the two elements separately. The copper protects the zinc while the zinc supports the copper.

Just like the soul with two bodies surrounds the half breed one, protecting his surface from dings and scratches. Maybe not physically, he does tend to get beat up a lot in his fights, but mentally and emotionally, it is there.

The half breed's soul is what the soul with two bodies revolves around. The relationships may get a little mixed up at times, but both bodies are always there for the half breed.

Aw, screw it. Forget those two theories...

Kikyo, Kagome and Inuyasha are like a Twinkie.

Kikyo and Kagome are the creamy sugary center surrounded by the angel food cake of Inuyasha.

Yeah. That works...

Fin.
