From what Kishiro told to his friend about what Oden's wife said, I take it it was some kind of a spell to send 9 people to 20 years ahead."Heavens hear me! For I pray. Cast nine shadows across the moonlit nights of twenty years." Apparently he and Orochi mistook this spell to a curse and thought this is a prophecy. There are 11 graves. Oden, Oden's wife and 9 more, So the 9 people in the prophecy are Momo, Kinemon, Kanjuro, Raizou, Kiku and 4 more who were sent to 20 years ahead in time.
