Ceroba Ketsukane is a kitsune-based monster living in the Underground, who tried to find a way out. The experiments previously killed her husband Chujin and her daughter, Kanako. She lives in the Wild East, alongside Starlo, her childhood friend. Ceroba is an emotional mess, but tries to hide it. Against the player, she is remorseless, fighting them with magical blasts or vortexes out of her staff. Ceroba is determined to kill the player, not even giving up in her final moments.
