The costume, which was 4.7 meters (15.4 feet) tall and weighed 2.7 tons, was deployed on-stage while Mizuki sang her hit song “Hime Murasaki”.
Afterwards, Mizuki stated that she had “finally achieved her dream” and that she could understand a little better the feelings of fellow-performer Sachiko Kobayashi.
Mizuki’s evolution to “last boss” status took place at the Saitama Super Arena in front of some 26,000 adoring fans on March 12, 2017.
