Rizuna is probably my favourite of the JP ASMR girls that I know about. Pretty nice voice, and a body that is just exquisite. It is a shame that she isn't shared much compared to the others like Can, Rik, and Mac. Not to mention quite a few links in the content thread are down.
Her cosplays always look pretty good to. It doesn't look like she uses some cheap materials when making or even just outright ordering them.
