Saber comes from Fate/stay night, first released as a visual novel in 2004 and later adapted into anime series and films. She is the Saber-class Servant summoned by Shirou Emiya, later revealed as Artoria Pendragon, the legendary King Arthur. The formal way she is named by class reflects the Holy Grail War, where Servants hide their true names. Clips identifying her spread through anime forums, AMVs and social edits, and the line remains popular because it sums up her mystery, nobility and role in one short introduction.
