Just two months after forming, GRAND GUIGNOL (グランギニョル) suddenly disbanded amid backlash to their mid-December 3-day tour using the World War II atrosity of the Himeyuri students as a theme.

Ill-advised X (Twitter) posts from the group as well as formal media coverage of the outrage led to the sudden cancellation of the remaining part of the tour in addition to a suspension of activities as well as the cancellation of upcoming performances. By the end of the week, GRAND GUIGNOL (グランギニョル) announced their official disbandment and refunds for ticket holders.
