=== Prologue ===

-On that day, I woke up in a white world.

I had no memory before I fell asleep. The only thing I remember is...
that I am "human" being.

In my sight, there is a vast world of nothingness...
and a huge world tree shining in rainbow.

Why has the world become like this?
What does that world tree exist for?

Why I can recognize "that" is
a world tree by just one look?

I must understand...

about this world,
and about myself.

I had nowhere to go anyway,
so I started walking to the tree.
