Suddenly one day the waves of darkness messed up the prism of light and began to inhale the light of the world. Then the night went on the morning light was lost and people were living anxious lives in the dark. On the other hand the gluttonous wizard Cotton who is completely indifferent to such things does not know the request from Fairy Silk. However when I heard that I could get my favorite Willow when I got rid of the monsters it was so glittering! Anyway the journey to explore Cotton Willow begins.
