Having had no contact Sakurako for a while, Shotaro recalls how he first met Sakurako two years ago. While looking into the disappearance of one of his neighbors, Yachi, Shotaro became introduced to Sakurako's love of bones and received her help in finding where Yachi went and what she was searching for. Finding the bones of Yachi's father, Sakurako deduced that Yachi was the one who killed him when she was young, which she had always regretted. Remembering the impact that incident had on him, Shotaro rushes over to see Sakurako, stating his determination to remain by her side and help her face Hanabusa.
