Keisuke is the vice manager of the Hotel Primeiro, a warm respite for the hearts of weary travellers. He is an overly serious individual who strictly enforces the hotel’s rules. In the comforts of his room, he listens to a melody over and over again. After he heard a similar music coming from the lobby, he headed there to find a girl playing the guitar. When he asked her for the name of the song she was playing, she rushed at him with a knife. Fortunately, he was able to stop her by grabbing the blade. She collapsed to the ground, not knowing why she just did that.
She later apologized for the incident, introducing herself as Sarah and requested to listen to his tape after he mentioned it. The soothing melody made her cry and she explained that it was composed by her precious friend Lucille who had been murdered. It was Lucille’s wish to let everyone her hear music and become happy, so she was travelling around and playing her songs to people in order to fulfill this wish. However, she decides to stay in the hotel for now.
