She is first met by central human character Keisuke Shimizu when he is exiting the ancient Okinawan cave. He at first mistakes her for a reporter, but she then reveals that she is the Archaeologist from Shuri University that they had sent for. Upon entering the cave, she begins to decipher the cave drawings and the prophecy they tell. On the plane back to Tokyo she encounters Shimizu again and tells him she's taking the idol of King Caesar back to the mainland for study. On the plane it becomes apparent that the prophecy may be coming true. She takes the statue to the home of Professor Wagura (uncle to Shimizu) and does further research into the prophecy and what it means. Saeko later attempts to return the idol to Okinawa, but it is stolen and briefly lost. She is present when King Caesar awakens.
