Vio lives deep in the forests of Withering Woods. Chosen to be the Nightmare King's vessel at a very young age, she struggles to fall asleep and experiences terrifyingly lucid dreams. She frequently wakes in the middle of the night in fear of the day she’ll be face to face with the Nightmare King. Despite the lack of sleep, she’s friendly, peppy, and incredibly kind; she's spent most of her life helping others out, even if it costs her plenty. She runs a rebellion group with her partner, Red.
