Each enemy has their own type of Uzaina, usually reflecting the villain's element, such as Karehan being able to manipulate anything made from wood or plants. Each Uzaina has their own type of spirit insides them, as shown by the different colored spheres that appear when beaten.
List of Uzaina
- The name is inspired by the Japanese word for "it's annoying".
- Each Uzaina has a "U" in his forehead. Maybe, is reference to the first letter of his name.
