===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.
