She first appears in “Episode 05: Dancing After School” by attacking Shirou Emiya after he protects an unconscious student at school from an attack. Shirou pursues her into a nearby forest, and is almost killed before Rin Tohsaka is able to save him.
Later a powerful magical barrier appears in the school and several skeletal Golems flood the hallways. Saber and Rider then have a showdown. Rider is defeated, but as she fades away, Caster appears in her place. Rider’s true body is found elsewhere.
