Every person is born with a conscience. It tells us what is good and what is bad.
People in this world are born with their conscience in the form of a good spirit and a bad spirit that do just that. But they don't get any benefits from the spirits.

When they turn eighteen their subconsciousness chooses the spirit that will be their companion for the rest of their lives.
When the spirit is chosen they get benefits from the spirit's powers.

But, as you can imagine unconscious decisions don't always make the decision we want.

Notes:
I didn't use any movies or series for inspiration, the story is my original work.
This is just the result of my weird imagination and brain thinking about what that character would do and telling me what to write. I hope you like it :)

It's just a story, like all of my other stores. It doesn't have a deeper spiritual, moral or ethical meaning.
