Stefanie Joosten (/ˈjoʊstən/; Dutch: ; born 5 August 1988) is a Dutch model, singer and actress living in Japan. She first gained widespread public attention when Japanese developer Konami revealed she would be providing the motion capture, voice and likeness for the character Quiet in the 2015 video game Metal Gear Solid V: The Phantom Pain.
Stefanie Joosten was born in Roermond, Limburg, in the southeastern Netherlands. She attended the Bisschoppelijk College Broekhin in Roermond, where she followed a bilingual (Dutch and English) course. Claiming to have been obsessed with the otaku culture since she was young, Joosten decided to study Japanese language and culture at Leiden University. In 2009, she went to Kyoto for a year as part of an exchange program. It was after this experience that she decided she would move to Tokyo after earning her degree back in the Netherlands.
While in Japan, Joosten came into contact with several modeling agencies that happened to specifically seek Western models. She started doing modeling jobs in 2011. After doing numerous small acting roles and commercials, she got a call from a mystery agent who was looking for models to help with an undisclosed video game. Joosten, who had been into Japanese games since childhood, became suspicious when she recognized one of the people during the auditions. She later found out this was the famous video game developer Hideo Kojima, giving her an idea of what she had auditioned for. She was chosen as both the visual and voice model for Quiet, a central female character in the Metal Gear game Metal Gear Solid V: The Phantom Pain.
