Padudu, a young apprentice witch of only 12 years old, was selected as the representative of her town in the coliseum. Dressed in her enchanted fish costume, which both kept her nourished and warm, she began her journey. However, she was unexpectedly carried away by a river and found herself stranded in Dance Valley. The mayor of the valley, Koffy, imprisoned her in a dungeon in hopes of eliminating a rival candidate for their own coliseum games. Fortunately, Padudu met the enigmatic Nonononn, another imprisoned witch, and the two collaborated to fight for their survival. The exhilarating journey reached a conclusion as the news of the enchanted land of witches, Blue Gender Trailer, was announced.
