Yumebakura is a man-eating Ayakashi sent by Doukoku to put Dayu to sleep and remember her origin by exuding a sleep-inducing mist. Once his job is done, he then enters the dream world so he can eat the dream incarnations of his human victims, thereby killing them. However, Blue and Green enter the Dream World after him and force the Ayakashi out and broke his mist inducer, breaking his hold over his victims. Appearing the next day with the Meimo Kyomuken and intent to eat humans after convincing by Doukoku and Shitari, Yumebakura is defeated by Super Shinken Blue and destroyed by Daikai Shinken-Oh with the IkaTenku Buster.
Baku devours dreams and nightmares and looks like a tapir.
