After a colleague described her drawings as "Saiaku" which means "Worst" in Japanese, she added "Saiaku" to her real name "Nana" and took the name "Saiaku Nana-chan." Since 2015, she has been holding solo exhibitions mainly in Tokyo, Japan. Not limited to the field of art, she is active in a wide range of fields, including collaborating with musicians and providing goods, as she herself is a music lover. She is not affiliated with any gallery, but runs her own gallery that she set up by herself.
