On 2 March 2014, at the end of the band's
second show at
Nippon Budokan, two European shows, Legend "Y" and Legend "M" were announced; these shows, taking place in Paris, France and Cologne, Germany, respectively served as the 15th birthday celebrations for
Yuimetal and
Moametal, respectively. The world tour was confirmed on 7 May 2014 with a trailer and several dates announced for European and Japanese legs, marking the second episode of the Metal Resistance. One of the dates included an appearance at
Sonisphere Festival in the United Kingdom on 5 July 2014; Alan Day, of the
Kilimanjaro Live group (Sonisphere's event promoter), formally invited the band to play in the festival following a successful fan-driven campaign entitled "Babymetal For Sonisphere UK 2014", which Sonisphere later acknowledged on its website. Initially scheduled to play on 6 June at the tent at Bohemia Stage, the performance was moved to 5 June in order to upgrade to the Apollo Main Stage. The next show in the country was set to occur at the
Electric Ballroom in London, but was later moved to
The Forum due to tickets quickly selling out. On 1 June 2014, a tour date for the United States was revealed. On the tour, the band performed as an opening act for five shows from
Lady Gaga's
ArtRave: The Artpop Ball tour, from 30 July 2014 to 6 August 2014, and
Summer Sonic Festival 2014 in Japan on 16 August and 17 August 2014. After their performance at Summer Sonic in Chiba on 16 August 2014, another leg, titled the
Babymetal Back to the USA / UK Tour 2014 (stylized in all caps), was added to the tour, adding dates in November 2014, with the USA concert was to be held in
Hammerstein Ballroom in New York City on 4 November, and the UK performance held in
O2 Academy Brixton in London on 8 November, which would mark the start of the third episode of the Metal Resistance. On 13 September 2014, Babymetal announced the show
Legend "2015": New Year Fox Festival to be held at Saitama Super Arena, Japan on 10 January 2015, after the end of the tour. In addition to official tour dates, the band also performed secret dates, with the umbrella term "Apocrypha". Knowledge of these performances is generally restricted to members of the "Babymetal Apocalypse Web" official fanclub. The text supplied marked the first time the term "The One" was used by the band; in this instance it referred to a secret society present since the performance
Legend "I". ==Broadcast and recording==
