Kindaichi Shounen no Jikenbo EP56 - Site of Demon God Murder Case File 1

Hajime and Miyuki are invited by their senior Satsuki Munakata to her home in the remote Majin Village and they take his cousin Fumi. On the way Hajimetells Fumi about the first time they visited Satsuki to help dig for historical artefacts. Munakata says there are only three families there; Boukyoku, Hoko and her own, Nanakakami. The fourth Doutakute residence was burned down ten years earlier. in her house they have a effigy of the Magamitori God which the family worships as the guardian of the village. The objective of the dig is to find four "devil's artefacts" somewhere in the village which are said to bestow fame and fortune. Dig coordinator Kunamori explains how Bunzaemon originally had the artefacts and became famous. The artefacts were then gathered by Kichieman Munakata, Satsuki's grandfather who became very wealthy, however tragedy has befallen his descendants and he buried the artefacts somewhere in the village. Toribeno, Kunamori's assistant, displays four replicas made by Kichieman; a necklace, blade, mirror and bell. Later, they all go to the Magamitori cave where the dig will take place and after sliding aside the "mirror rock" they dig for a while but find nothing important. After dinner, Miyuki sees a Magamitori figure at the cave and when they investigate, they find Yamato’s body inside the sealed cave.
