>>85741405Mori is definitely ride-or-die for hololive now, but she won't stick around if her genmates go. She loves her friendships and will lose her spark if she loses them.
Kiara talks a lot about it, like you said, but what would get her to quit is a want to finish up, like Aqua did with her big banging out. At the same time she has been ready to move on for like two years.
Gura is, well, Gura. She knows her lucky her place is but she also could leave at any time because what made her motivated to stream in the first place is gone with Cover changing from 2020/21 and her gen not being unified anymore.
Ina is stable, her quitting would be because Myth graduates and only if she doesn't have another dream within hololive to fulfill. She's the most grown up of them all.
