The band decided to release three singles prior to the album , as a way to alleviate the pressure that the band felt to release new music after the success of their previous album '' Kikuuiki '' ( 2010 ) , and as a way to show the album 's development process . The first single " Identity " , a song originally written during that album 's recording sessions , was released three months after '' Kikuuiki '' . The band intended to release " Endless " as the album 's second single , however as they were not fully satisfied with the song , released " Rookie " in its place in March 2011 . Just prior to the single 's physical release , Japan experienced the 2011 Tōhoku earthquake and tsunami on March 11 , 2011 , which made Yamaguchi re-evaluate the reasons why the band made music . Originally , the album 's documentary concept focused on themselves as a band , but the disaster prompted Yamaguchi to take inspiration from world events such as the earthquake . " Bach no Senritsu o Yoru ni Kiita Sei Desu " , released as the album 's third single in July , was written as therapy for Yamaguchi during this time
