Ok so I've looked through ever collab between Reine and Robocosan. And I was proven right yet again: Reine definitely hates Robosa.

If you look at this stream in particular at 13:05, you can just hear the hate in her voice. Even I was surprised when I heard it, I mean that is a LOT of hatred: https://www.youtube.com/watch?v=cnWV74bdjws

Then, towards the end of this stream at 1:44:48, Reine dies and Roboco laughs. Reine instantly stops laughing, no doubt because of the amount of anger she was feeling towards her. I bet in that moment she never wanted to collab with her ever again. She is like literally on the verge of yelling at her you can hear it.

I think this thread should be devoted to seeing if we can find a way for them to make up for whatever fight they're in.
