Two sleeping giants have woken up. They are going to eat up the whole world!
"What shall we do?"
"Let's run for our lives!"
"Let's obey the giants, perhaps they may change their mind."
"Let's face reality. What can we do with such a strong enemy?"
In ancient times, little David defeated Goliath in the wilderness all on his own. Now in Rainbow's Ending, the one who stands up against the giants is also a youngster, Rainbow. Her courage makes a great difference to the fate of the whole world.
