ARIYASU Momoka who is a member of the "Momoiro Clover Z" and is known as "Green of MOMOKURO/Momoclo" happened to be spanked by (KAWAKITA)Nawo who is the drummer and vocalist of Maximum the Hormone,according to what Nawo said on a radio.
Momoka had shown her back to others and said "Please!(beat me on back)" in a dressing room because she wanted to cheerup herself before her stage.
When she did that to Nawo,Nawo had no idea what happened before her,then she thought Momoka presented her bottom to her and wanted to be spanked by Nawo,so Nawo gave her a good spanking.
