Found out on vt but it seems like the Idol TOS was updated earlier today.

Looked at
Wayback and these 2 sections weren't there yesterday.

I checked the moment when Yuko first appeared and she seemed to be doing alright. Even made a correction joke right after she showed up. They were just vibing and having a good time which is probably what she needed.
And yea it seems like the EN girls have an issue with raiding the HE girls. I think they have separate calendars or something. About a month or so ago, Rin took a while looking for people to raid and said she has to remember to raid the HE girls before going into Katta or Nikki's stream. And the HE girls have raided into the EN girls multiple times so I don't think it's a management thing.
