Masahiko left home because he couldn't handle the lifestyle his family was leading. He ended up getting a job as a driver for prostitutes, with no academic training or concern about the future. His life changed completely when a woman called him to say that his sister had died. Reluctantly, he returned home to say goodbye and discovered that the last CD his sister listened to before she passed away allowed her to experience astral travel and out-of-body experiences. Masahiko tried to understand why this CD provided such an experience and began searching for more information about jazz music's connection to astral projection.
