Gura might have all the attention but she clearly isnt cut out for the Hololive life after the seemingly endless bouts of burnout.
Kiara in her lore failed as an idol before joining Hololive, came back as a virtual idol, only to fail again. That's why she's the ccv runt of the entire branch. What's holding her back is her horrible attitude towards everything and everyone.
Cali literally doesn't deserve her record deal in any way, shape, or form. Neither does she respect the company she's in. Only recently did she start pandering to idol fans after years of fighting against them because the record label forces her to. But she still plays as that, self titled, "cringe queen" rapper persona which is holding her back.
Ame is also burnt out and stepped far away from the spotlight that she strongly had a grasp of from the early beginning. She easily could've gone the "started from nothing" to the groups "idol with a soul" but ended up wanting to stop being the head of Myth and chill in her crib.
Ina is that "diamond in the rough." Clumsy, artsy, cute girl who worked hard and grew alongside her company to become the idol she is today. She's the fan favorite, right after Gura (if she streams), within Myth these days. And with a huge appreciation and fangirl attitude towards Hololive, since day 1, Ina is easily Myth's chosen idol.
