Apparently the adult film actress Asuka Kirara, 明日花キララ, have joined the Japanese hip hop and rap scene it seems.
Just dropping this new track called “Cho Ero De Gomenne” “Sorry for being extremely erotic” on Twitter on and YouTube. The response is very mixed if you read comments from Twitter and YouTube. Previously there was a track by JP THE WAVY called “Cho Wavy De Gomenne”, meaning “Sorry for my extreme wavy” which has the same kind of beat and style.
