Jiugenka Users are ability users that assign a specific form to their powers, such as a type of weapon. This image is usually chosen as early as childhood, and while it can be manipulated somewhat (in terms of size or number, for example), the basic shape is fixed and cannot be changed. In this respect, jiugenka users are somewhat limited in that they seem unable to fully explore the element from which their powers originate. Another apparent characteristic of jiugenka users is that the assigned form of their power vanishes after use.
