Japanese sculptor and manga artist who creates works that feature female genitalia and are often modeled after her own vulva. Her pseudonym translates to “good-for-nothing-girl,” and her real name is Igarashi Megumi.

In 2014, she was arrested following the creation of the Manko Boat, a kayak with an opening attachment modeled after a 3-D scan of her own genitalia, for which she drew financial support from an online crowdfunding platform. Months later she was arrested again at an exhibition of her diorama works. Her arrests launched a frenzy of media attention and led to an international outcry of support for the artist. Many disputes about women's rights, artistic freedom, censorship, and double standards in Japan emerged due to Igarashi's arrests.

In 2016 she married Mike Scott, frontman of Scottish folk rock band The Waterboys.
