This is an important notice regarding today and tomorrow’s performance LEGEND – S – BAPTISM XX – at Hiroshima Green Arena on December 2nd and 3rd.

One of the BABYMETAL members YUIMETAL is unfortunately not feeling well and doctors have suggested that it is in her best interest to not perform over these two days.

We regret to inform this unfortunate news and truly apologize in advance for all of the fans who were looking forward to seeing all three members play.
