Padudu, a 12‑year‑old apprentice witch, is chosen to represent her town in a coliseum contest. Wearing a magical fish costume that keeps her warm and nourished, she sets off on her journey. En route, she is swept into the river that leads to Dance Valley, where Mayor Koffy captures her and locks her in the dungeon, hoping to eliminate the competition for Dance Valley’s own coliseum candidate. In the dungeon Padudu encounters the mysterious witch Nonononn, and together they engage in a magical fight for survival. At the end of the Blue Gender trailer, the phrase “Magical witchland” appears. This is the online version of Mahou Yugi.
