Anastasiya Pavlivna Gryshai, better known by her stage name Wiska, is a retired Ukrainian pornographic actress and model of Belarusian origin. Born on October 17, 1985, in Gomel, Byelorussian SSR (now Belarus), she grew up in Feodosia, Crimea, Ukraine. Facing financial hardship after her husband Oleksandr's imprisonment in 2003 for arson related to a business dispute, Anastasiya entered the adult entertainment industry in 2004.
She filmed her first scene in Russia, earning $500 per week, and went on to appear in over 40 hardcore pornographic films by 2008, working with renowned performers like Rocco Siffredi. Her career gained notoriety in Ukraine, leading to media exposure and scandal. In 2010, facing child abuse allegations and anti-porn laws, she fled with her family to Kyiv, then to the Czech Republic in 2012, seeking political asylum—the first pornographer to do so in the EU.
Residence was granted in 2013. Now a mother of three, she has retired from the industry and lives near Prague. Measuring 5'7", she used aliases such as Vuiska, Wika, Anastasia G, and Nastia.
