>>56918477well homo isn't technically one of them, it'd fall under Lust if you had to put it somewhere.
So for Wrath, Envy and Gluttony, I'm going to go out on a limb here and say Kiara fits the bill for those three. Not Gluttony as in literal food overeating, but metaphorical gluttony. She wants all the attention she can get.
A couple other holos have a -chou nickname, so she's got to start calling herself Tenchou
a couple other holos have a yuri pairing to gain in viewers, so she latched onto Calli like a lost toddler.
Coco had an event-like show where she invites other holos onto it, so Kiara has to make Holotalk.
thinking back on it, I almost feel sorry for her that she was the last in her gen to reach 1M. (That's where Envy kicks in) Not that I disagree though, everyone else is more entertaining in the actual streams.
I don't really think she's graduating any time soon, she's got too much investment in the Idol scene, and the way she acts, I can tell that she's the most socially normal of her group. The others all display some level of awkwardness or autism, but Kiara just seems like the most socially put together.
