As a Sagacious Spirit who has purified her grudge towards Chang'e, Junko is described to be a being made out of pure fury. Her hatred is strong enough to persist after she murders Houyi, her first grudge and the person responsible for her son's death, to the point where she currently targets all of her animosity towards Chang'e and the Lunarians despite having nothing to do with her son's death. Junko doesn't seem to care for intricateness, preferring to do things with a straightforward attitude
