five songs from the album was posted on YouTube, along with a teaser for a live music clip of "Gimme Chocolate!!". To commemorate the release day of the album, Tower Records Shinjuku sold "Festival of 25" merchandise, with the store ultimately selling over 1,000 copies. The album was also released in a special limited edition titled Babymetal Apocalypse Limited Edition, exclusively for members of the group's "Babymetal Apocalypse Web" fansite, and in a CD format with alternate versions of two of the songs. On July 26, 2014, the band re-released the limited edition version with a special cover to commemorate the band's 2014 world tour. In mid-2015, the album was re-released worldwide under different record labels with two bonus tracks: the new song "Road of Resistance" and a live performance of "Gimme Chocolate!!" from O2 Academy Brixton. When asked about the re-release, Nakamoto explained, "Obviously, we don't come to America often. It's very difficult, you know, schedule-wise and everything. With this album finally being physically available here, I feel that, hopefully, the album will be the medium that keeps the fans close to us. They will finally be able to hold it in their hands. Even though we're so far away, this album's going to connect us with fans again and we just want to keep that relationship going." Tour Shortly after the release of the album, the band performed two shows at Nippon Budokan to a sold out audience, where they performed all songs from the album with their accompanying band, Kami Band. After the end of the second show, the band announced two shows to be performed later in the year in Europe, which was later revealed to be a part of the band's first world tour, the Babymetal World Tour 2014. In 2015, the band embarked on the Babymetal World Tour 2015, with more tour dates in North America and Europe.
