The Servant of Shinji, first seen scouting around Homurabara Academy. Rider is silent, sultry, and vigilant, never hesitating to shield her Master from harm. With Shinji incapable of lending any mana to her, she is forced to seek alternative means to augment her abilities. To compensate for her weakness, Rider employs covert battle tactics and takes full advantage of any territory around her. Her weapon of choice is a pair of long iron nails fastened to opposite ends of a single chain, which she effectively thrusts from distances.
