matou sakura (deen s&m)
Matou Sakura from Fate/Stay Night wearing the bondage outfit from the 2006 anime series by Studio DEEN. Note that the costume is entirely DEEN's creation and is not based on any of the official source material or character designs. Coincidentally or otherwise, the costume does look rather similar to the one worn by Scathach from Fate/Grand Order.
