So it ended up being a bit of a one way conversation, because I could only manage simple replies while Kamui could at least translate what she said.
Then she asked me if I wanted to watch her do one more run with Gain (she was originally using Wild Snail). Well, of course I would! It's one thing to watch a livestream. It's another thing to watch a run live!
And what a run it was. She nailed pretty much all her strats, didn't suffer any medal drops (at least, not without quickly picking up another 10000 point medal to prevent the medal chain from resetting). And she managed to clear as well.
