I feel like Angerme always adds new members before the newbies get their chance to shine. I love seeing new members, but Angerme needs to calm down. You just added three new girls.
It doesn't help that their members keep graduating within such short span of time. I mean from 2019 to now, they have lost a total of 7 girls (Ayaka, Rina, Kana, Haruka, Mizuki, Musubu and Momona).
When you compare to other groups within the same period, MM lost 1, J=J lost 5 (though this is pretty bad) and Tsubaki lost 1. And the number of girls lost in Angerme are equal to those who left from the 3 groups combined.
