BABYMETAL has a new profile pic (similar to previous one, but no more Chosen 7) on their Amuse profile. Su and Moa are now on that page again (after the 3 members disappeared from it around a year ago).
BABYMETAL Announces Further Details And A Foreign-Exclusive Lottery For The “BABYMETAL RETURNS – THE OTHER ONE -” Shows
The lottery opens up in less than 24 hours. There appears to be no THE OTHER ONE membership requirement, but that also means that SUPER MOSH'SH PIT tickets are not available.
