For some reason, EN management seems to be hellbent on distancing the girls' background from the JP talents based on their significantly more chuuni setting. Probably they think edgier characters are much more liked in the west or something like that. The only one that really follows the JP-style backstory is Kiara: a supernatural being doing something mundane/ordinary, which is also more in line with the usual idol tropes. I bet this is where the part-time warrior aspect of Kiara's came from: the management trying to tie her into the overall edginess of the group.
At a first glance, this group seems to be even more chuunier than HoloMyth, so chances are that none of them will follow Kiara's path.
