Into the Darkness
Shinpei learns the truth about Ushio's death. From the video left behind by Ushio and Shadow Ushio, he believes that there are clues about the "shadow" on the mountain. There, they find the old ward of the Hishigata Clinic, which is the family home of Sou. When the three of them arrive at the old ward, they see a statue of Hiruko sitting in the clinic and a hidden door leading to an underground bunker further inside. The group tries to go deeper, but the hidden door is locked.
