Cotton 100 Percent [Collector's Edition]

The world has fallen into darkness, and the fairy Silk sets out to look for help. She crosses paths with a young witch called Nata de Cotton, who seems rather uninterested in helping her. That is until Silk tells her that along the way, giant Willows, a candy that Cotton has a massive craving for, are waiting for her, so the two set out to find out what's causing the darkness... or look for Willows!
