突如として現れた謎の第三勢力の首魁。

光り輝く剣を手に、圧倒的な破壊の嵐を吹き散らす。
セイバーとして極めて高い能力を持つが、
果たしてその正体と目的は―――

「騒がしいな、人間は。死体に群がる蟻のようだ。
　前回と何も変わっていない」

The leader of a mysterious third faction that suddenly appeared.

With a shining blade in her hand, she creates an overwhelming storm of destruction.
Her powers as a Saber are incredible, but just who is she, and what does she want?

"Humans are so noisy. They're like ants crawling on a corpse.
Nothing's changed since last time."
