S1·E16 Return of the Assassin

Mozu teams up with easy-going Kikusaki (Shikigami - Houjou no Ruri) to search for more Toujin stones, and a deranged Izou goes with them, hoping to destroy Riku and Kogenta. Teru meets up with Riku and Souma. They head into a desert field of Fukumaden, where they do battle with Mozu, Kikusaki, and Izou.
