Rider

The Servant of Shinji, first seen scouting around Shirō's school.

Personality
Rider is silent, sultry, and vigilant, never hesitating to shield her Master from harm. Her legendary counterpart is Medusa.

Magical Skills
She employs covert battle tactics and takes full advantage of her surroundings. With Shinji incapable of lending Mana to her, she is forced to seek alternative means to augment her abilities such as putting magical seals all over Fuyuki High School that, when activated, drain the life out of any living creature within. This is actually one of her Noble Phantasms, Blood Fort Andromeda: Outer-Sealing Blood Temple.

Weaponry
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. Her primary offensive Noble Phantasm is Bellerophon: Bridle of Chivalry, invoked while riding upon the winged horse Pegasus and is summoned when she stabs her neck. It drives the Pegasus into a killing fury, turning the Pegasus' charge into a wave of energy capable of causing mass destruction.

She wears a blindfold, actually another Noble Phantasm, Breaker Gorgon: Self-Sealing Dark Temple, which seals away her powerful Mystic Eyes that are capable of paralyzing any weaker being who looks at her.
