>>7485660My admittedly shitty opinions that people should take with a barrel of salt
Health
>Ayame>RushiaThey're consistently on break due to sickness. They are likely to leave for their health
Career
>Mori>Haato>ShionThey're just using vtubing as a stepping stone on their careers/creative pursuits. Ditto the zoomers such as Shion and Haato who will likely branch out and create their own brands in the future.
I didn't include Suisei, because I suspect she has a fair bit of emotional debt owed to Hololive for giving her a chance.
Personal Issues
>Watame>Korone>MatsuriThey have personal problems that bubbled up more than a few times both in-stream and on twitter. Korone has outright stated considering graduation.
Money
>Choco>Mel>Lamy>Luna>AmeliaThey're only in it for hololive's brand and the money it drags in. They will leave as soon as the money stops flowing, or if they find better contracts.
Menhera
>PolkaSuicide
