Fate/Zero

This episode focuses on Tokiomi's daughter, Rin, and her involvement in the Fuyuki City Kidnappings. Despite her young age, Rin is determined to follow in her father's footsteps as a great mage. With the Holy Grail War starting soon, Tokiomi sends Aoi and Rin away for their own safety. At Rin's new school, several children, including her best friend Kotone, have been kidnapped by the Fuyuki Serial Killer. Wishing to save Kotone, Rin heads to Fuyuki City alone. Using a mana detector gifted to her by her father, she eventually finds Uryuu using a magic bracelet to hypnotize children. Rin follows Uryuu to his hideout, where she is found by him. Rin overloads Uryuu's bracelet with mana, destroying it, incapacitating him and freeing the children from his control. With everyone safe, Rin heads home only to be ambushed by one of Caster's monsters; however, Kariya comes to her rescue and later hands her to Aoi. Kirei, who had been spying on them through Assassin, orders him to continue monitoring Kariya.
