Crayon Pop returned to Japan and held a mini-concert on 6 January 2013 in Shibuya, Tokyo. Tickets went on sale on 11 December 2012, and sold out in less than an hour. As a result of considerable demand from fans unable to purchase tickets, Chrome Entertainment announced that another Japanese concert would be held at a later date, and a second mini-concert was staged in Osaka on 22 February. On 25 January, Crayon Pop began promoting the remixed version of "Bing Bing", which included a popping dance break to Daft Punk's "Harder, Better, Faster, Stronger" instead of the original rap verse. They had a "delinquent schoolgirl" concept with new choreography, and wore tracksuits or school uniforms with tracksuit pants. On 19 May, a third Japanese mini-concert was held in Shibuya, Tokyo. A new Japanese member, Arisa, was to be revealed at this concert, but she had withdrawn from the group before the performance.
