A Trap is Set on the Evil Mountain

S1 E6: Rikuo and his friends arrive at Mt. Nejireme, which happens to be the domain of a Nura Clan affiliate, the Gyuki Clan. The mountain is oozing with yokai energy, and Yura the onmyoji is not the only one who perceives the eeriness lingering in the air. Rikuo notices how frightened Maki and Tori are, and he suggests they forget about this trip and go home. But Kiyotsugu says this is how a yokai trip should be, and he ignores Rikuo’s suggestion. When the group arrives at the hotel, Professor Adashibara, the yokai expert, warns them not to go outside after twilight.
