"the peggies" met each other back in 2009 while in high school and they have been together since then, they released their major debut in 2017
the members wanted to make clear that this isn't due to a fight between them or anything like that, they simply decided they wanted to go different ways, all members stated they are irreplaceable friends to each other and that their bond is going to continue even if they aren't part of "the peggies" anymore
they are going to separate after their tour ends in September, just recently they did the opening theme for the anime "In the Heart of Kunoichi Tsubaki"
