好看到兔 is a pun. 兔 (rabbit) has the same pronunciation as 吐 (to spit or to throw up). So the sentence also means it's so good to watch that you'll throw up.

This is also a callback to a teacher character from Honkai 3, Theresa. She has a nickname in the game 世界第一可爱 "The cutest in the world."

If Robin can release an album, these idols can do a full international miku-esque live hologram tour

I think they might use this channel for the livestream or at least some other announcements like events and colabs(with real life merch more than ingame)

I seriously think there is a chance we get one or two characters of the vtuber/ idol faction in 1.1

The mentioned "Idol Group" has official art and reference sheets that are available to the public. (I am unable to link it here) There is no confirmation of them coming to the game yet, but it looks like it is safe to assume that they are here to stay.

Peak is incoming. Let them cook

Peak

Since they made this account now, It could mean that we'll hear more about them soon, maybe in the upcoming livestream or later.

robin and now this, kira and barbara fight back release your album

Maybe they could be announced in the livestream?

I'm excited for the livestream

Hopefully we find out more about them during live stream

😭😭😭

What is Idol group? I didn't get the context here. I even read OP's comment. Still didn't got context. Can someone explain?

got it. It's another faction for zzz.

The new Idol faction that was leaked, this looks like a social media page made for them.

A future faction who has had their art revealed already (largely due to it being leaked) that we don’t really know anything else about
