Yoshiko is traveling throughout the land in search of her ancestor's relics. In Yamataikoku she looks for her ancestor's old armor crest, and in Izumo she looks for a Skull Mask that a book says was worn by her ancestors too. She doesn't know exactly where these lost relics are, but continues to investigate any pieces she does find. She hires the help of a passing Oni, the player, to assist in her search for these family relics. Though the player finds Crest Fragments and Skull Masks, they, unfortunately, don't belong to her ancestors. She is happy for the help the player presents her with, but she moves on to another town in continued search for her ancestor's lost relics.
