>>1687946here's an idea: the EN girls dont want to collab as much as /we/ want them to
Gura justifiably dont trust her japanese, and she talked at length about her anxiety over dead air
Ame is hesitant about collabs in general, and does it on occasion because going out of her comfort zone is something she tries really hard to do, but realistically, she doesnt speak a lick of japanese.
Ina was blacklisted for a while (if you believe the rrats of old) and is now focusing on getting out of her priestess duties that got unexpectedly extended
Mori is a workaholic and literally doesnt have the time
Kiara has JP collabs all the time.
