MCZ appeared on stage together with a popular YouTuber duo.

The day before yesterday, MCZ made a surprise appearance as a special guest at Heisei Flamingo's solo offline event "selectrain", held at Yokohama Arena, realizing a dream collaboration that fans had long been hoping for.

Heisei Flamingo is a female YouTuber duo consisting of childhood friends NICO and RIHO. Now in their fifth year of activity, they boast over 10 million total followers across social media and enjoy overwhelming popularity among teenagers.

They have openly declared themselves to be big fans of MCZ since the early days of their career, and on New Year's Eve last year, they made their first appearance as one of the performing acts at the "Momoiro Uta Gassen", where they shared the stage with MCZ for the first time.

MCZ's appearance at this event had not been officially announced, but it had largely been anticipated based on teaser images released in advance. Around 12,000 tickets sold out instantly upon release, and since they were already unavailable by the time MCZ's participation was hinted at, it is believed that there were almost no Momonofus in the audience.

However, the moment MCZ appeared, the venue erupted in excitement. They performed "Ikuze! Kaitou Shoujo" in a one night only collaborative special arrangement, sending the crowd into a frenzy.
