While searching for Hidemoto's lost seals, Rikuo and the Nura Clan encounter a forest of torii gates and a yokai who uses the gates to form a huge, treacherous labyrinth. Awashima falls victim to the labyrinth, which transports him to another dimension, where he will have to battle a powerful yokai before he can even attempt an escape.
