Patra aside, here's a couple that have some really good, relaxing ASMR:
Nekomata Okayu
Sukoya Kana
Kagura Nana
Mononobe Alice
Yozora Mel (members only, unfortunately, but she does have 1-2 that are available for everyone)
Pic actually related tho, Rena had a extremely nice ASMR stream for her 210-230k celebration stream -

Also shoutout to Ayaka Igasaki, not a vtuber but has some extremely good ASMR stuff and does have a model. She's a small-time VA and runs a doujin circle that has a shitton of R18 stuff on DLsite, but all her YT stuff is SFW and extremely good -
