not sure about recently but during her subathon she was pretty spicy when doing ASMRs.
edit: after conducting some serious in depth research, i can safely say she did not do such thing and you must be speaking about her asmr streams during her subathon.
One memory that sticks out from Mel's early days is one stream where she was about to cum after some edging and a guy went and donated a bunch of coins (like 10k or so) and that immediately took her out of the zone. Chat was pissed at the guy.. Hell; I was pissed at the guy. Ruined a......coming moment.
I've been looking for a scan too but I've never seen one of the second doujin. She said she will release it again soon so It might be worth it to grab a copy when she does
1. She did stream on her alt one. In that stream, she did not use her vtuber avatar but still using the same streaming room, and obviously her voice too.
2. She did not masturbate but only read some lewd lines and the usual asmr triggers
3. She deleted it
4. Unless you are her fan then it is not really worth it for trying to find that stream, i can barely say it was 16+
