She doesn't. At least not yet. Hopefully in the future, though....Also I wasn't aware she streamed anywhere else or had a roommate.
Also by "roommate" I mean in the context of vtubing (e.g. Hana and Nym), not an actual roommate. I'm not aware of any active "roommate" she might currently have, much less one who openly publishes unambiguously NSFW stuff; again, I'm hoping this might change in the future.
Go to the comments for the good timestamps, and then you can determine on your own whether she was playing with herself or "sleeping" at the end.
There's also her "sleep" RP asmr stream. The first half of that one is very spicy, especially starting at 56:15
Both may have gone on longer and/or been spicier, if her family had been asleep or at least quieter.
