Takafumi Horie's book "Zero: Adding a Small 'One' to Myself, Who Has Nothing" published in November 2013, led to the formation of the group at the end of that year. Their debut song, "Zero ~Hadaka no Oretachi~" (Zero ~Naked Us~), had its vocal recording on January 10, 2014, and was released digitally on February 28 of the same year. ※ Digital distribution and CD release at select stores: Zero ~Hadaka no Oretachi~ (June 18, 2014) An album of the same name as the single. Includes the three previously released singles, plus a new album track, "Akai Muffler" (Red Muffler). This is a very rare CD that is hardly in circulation. This is a brand new, unopened item.
