Sakurai's parents wouldn't let him move to Tokyo, so he was the only one left alone in Gunma, and became very depressed. He spent all his time alone, and to pass the time, he often went to concerts and watched bands live on TV, and he decided that he was sick of being a drummer and wanted to be a vocalist instead. Higuchi's brother Toll Yagami was also in a band, SP, and when SP lost their vocalist, Sakurai asked Yagami if he could be the replacement. Yagami politely refused his request, and SP broke up.
