Sitonai
Classification: Alter Ego-class High-Servant & Pseudo-Servant
Identity
Sitonai manifests as a Pseudo-Servant using Illyasviel von Einzbern's body, though she's technically a composite High-Servant housing three Divine Spirits. The Saint Graph registers under the name Sitonai because she's the dominant presence among the three—the one whose power consistently pushes through strongest.
Unlike most Servants, Sitonai's container isn't a human Mage. She's the Einzberns' latest and final homunculus creation, designed from the ground up to be the perfect Master. Her entire body is covered in Command Seals, and her Magecraft precision is first-class. She's also secretly capable of functioning as a Lesser Grail, making her arguably the most powerful vessel the Einzberns ever produced.
