Power User's are participants of the battle tournament, given powers by god candidates. They are given powers to turn 1 thing into another, which is somewhat alchemy. Kobasen refers to them as a and b, A being the pre-form and B being the after-form. They then fight for the god candidates and risk their lives into winning each battle, receiving one talent. Those who are knocked out by a power user loses their powers immediately and return to being a human. The consequences to hitting a human with their power however is that the power user will lose 1 of their talents. The winners of the tournament then chooses who they wish to be the next god and also receives the talent of blank. If a heavenly being is chosen as a power user, they become a Neo.
