Artoria Caster

Height: 154cm

The "Child of Prophecy" that saves the Fairy Nation. A special fairy that was dispatched from the inland sea of the Planet... from Avalon to the surface along with the "Staff of Selection". After drifting into the Lake District, she was placed on a boat along with many treasures by the decision of the Chief of the Mirror Clan, eventually reaching the coast of Tintagel and being raised as a fairy of Tintagel from then on.

In the Lostbelt, she is the same being as the "someone" who was eventually burdened with the holy sword in Proper Human History.
