>>73046298From a business stand point, Mori is probably the most marketable EN holo to any other company, bar Gura who most likely would be offered as a pet/product more than an actual asset to work with.
Koyori is just plain old building a big ass brand to her name as a content creator. Wouldn't surprise me if she even gets her own radio show at some point. Don't disregard her that bad though, the girl is as much crazy as Mori.
Kaela just has that mountain climber mindset that gives her magnetism to attract fans by default. She doesn't really offers anything that Cover would use in the same sense they are using Suisei or even Kiara imo
