|Season:||Samurai Sentai Shinkenger|
Yumebakura (ユメバクラ, Yumebakura?, 25-26): Yumebakura is a man-eating Ayakashi sent 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, Shinken Blue and Shinken Green enter the Dream World after him and force the Ayakashi out before breaking his hold over his victims. Appearing the next day with the Meimō Kyōmuken (迷妄凶夢剣?, Delusion Nightmare Sword) 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. His appearance and method of feeding is the basis of the Baku (獏?) of Japanese myth.
