Gyokko was shown to be an easily excitable demon, constantly fawning over new inspirations for what he deems his "art" or what he finds to be sublime, sometimes even going against his initial impressions. He was easily swayed into euphoria whenever Muzan was involved, trying not only to please him, but finding joy in being decapitated and having his head held by Muzan. He enjoys being humiliated by Muzan, and no one else.
