Kairi's Grandmother only appears in a flashback of Kairi's lost memories. In that memory, she is telling Kairi a fairytale about the light.
Her name and history remains in the dark.
The fairytale goes like this:
Long ago, people lived in peace, bathed in the warmth of light.
Everyone loved the light.
Then people began to fight over it.
They wanted the light for themselves.
And darkness was born in their hearts.
The darkness spread, swallowing the light and many peoples hearts.
It covered everything, and the world disappeared.
But small fragments of the light survived... in the hearts of children.
With these fragments of light, children rebuilt the lost world.
It's the world we live in now.
But the true light sleeps, deep within the darkness.
That's why the worlds are still scattered, divided from each other.
But someday, a door to the innermost light will open.
And the true light will return.
So, listen, child.
Even in the deepest darkness, there will always be light to guide you.
Believe in the light, and the darkness will never defeat you.
Your heart will shine with its power and push the darkness away.
Do you understand, Kairi?
