Born for the Light ~Wavelength Radiant Collapse~

There was Earth, and then there was the unattainable Sky.
One day, a giant Tree emerged, serving as a boundary between the two worlds. Indeed, it is said that there is a concealed Kingdom somewhere far away in the sky. Only there was no one to reach it yet.

Children are born on the Treetops, serving to achieve that goal.

And I am one of them.
