Sakura Matou

Sakura Matou appears to be a gentle high school student, but she carries the trauma of brutal abuse within the Matou family. Though she is biologically Rin Toosaka's sister, Zouken Matou adopted her to act as a vessel for his dark ambitions. She endures constant physical and mental torment, yet maintains a stoic strength driven by her long-standing devotion to Shirou Emiya. As the secret Master of Rider, she carries heavy magical burdens amidst deep-seated resentment and jealousy.
