First person: I (polite). Second person: Master. A stranger who arrived from a mysterious space-time known as the Servant Universe. Calling herself the definitive version of the Saber class, she carries out surprise attacks with the dignity of a knight. One wonders what being a knight even means anymore. Her appearance is a rough and sporty outfit that hardly looks like a Servant. Her blue muffler is a symbol of courage, and her hat is meant to hide her true identity and her cowlick. It's sticking out, though. It's sticking out a lot. She has blonde hair and blue eyes. As an anti-Saber decisive weapon, she is in a carnage mode where she stakes everything on her single holy sword to strike down all Sabers, yet she has opened her heart only to Saber Lily.

Her cowlick sticks out from her hat. She has blonde hair and blue eyes. First person: I (polite). Second person: Master-kun. She wants to lead as an older sister figure, but currently, she feels inadequate because she relies entirely on others for food, clothing, and shelter. At the same time, she finds a certain comfort in that relationship. Despite her energetic and polite behavior, she is very competitive (and since she's unaware of it, she can be incredibly tone-deaf), challenging everything and refusing to give up until she wins. She has a larger chest than Mysterious Heroine X.
