Gravekeeper
The gravekeeper is a character that Kujo and Avril met while looking for the victims that died in the clocktower. He starts telling Avril a ghost story about how he met a ghost when he was a little boy. He was walking in the graveyard when he heard footsteps and saw footprints on the ground.
It was later explained by Victorique that the ghost he saw was actually Leviathan and the gravekeeper was unable to see Leviathan since it was difficult to see a dark skinned person during the night.
