Akasaka Blitz
During the live performances at Akasaka Blitz on December 20, 2012, and at Makuhari Messe on December 21, 2012, a remix titled "Night of 15 mix." was performed, containing more elements of electronic music. The former took place on Suzuka Nakamoto's actual fifteenth birthday, while the latter was the opening song for the concert. Remixed by DJ'Tekina//Something, the song was later released as part of Social Reform promotional editions of the single "Ijime, Dame, Zettai", and later appeared on DJ'Tekina//Something's remix album "Kawa-EDM" (2016), re-subtitled as "Tekina Remix".
