S4E01 The Masks of the Shadowkhan

While attempting to summon the Shadowkhan, Daolon Wong accidentally summons Tarakudo, King of the Shadowkhan. With the enforcers in tow, Tarakudo sets out for Shendu’s palace. The Chans find themselves outmatched and Tohru is reminded of the Oni Demons of Japan. At the palace, Tarakudo finds the mask that Shendu used to control the Shadowkhan, The Mask Of General Rairakku. It ends up on Chow, but not before Tarakudo reveals himself as Lord of the Oni. Using a new incantation, Uncle creates a removal spell to take off Chow’s mask. Tohru then reads the script of a tablet in the palace. It tells of the 9 Oni generals , each with their own tribe of Shadowkhan. Each was imprisoned in a different masks, and if brought together, can summon enough Shadowkhan to cover the world in eternal darkness.
