Juon is based on the main antagonist, Kayako, from the film series of Japanese origin The Grudge.
Juon was a mother murdered by her husband due to an affair. Her spirit remains because of the rage left behind. Her twitchy, unpredictable movements, and clicking groan are due to the broken spinal cord suffered when she was murdered. She has long black hair, wide eyes, and wears a white dress.
Her ability is to enter a rage state where her speed is boosted significantly and can close the distance even on nimble survivors.
