Sola-Ui Nuada-Re Sophia-Ri

The daughter of the head of the spiritual evocation division of the Clock Tower of the Magus Association. She is engaged to Kayneth Archibald El-Melloi as a result of a strategic marriage arrangement. As her older brother (to whom the Sophia-Ri family had entrusted its magic crest) had achieved little success as a mage, her family sought to marry her to the celebrated Lord El-Melloi in an attempt to salvage the family name. Sola-Ui is introduced in Volume 2 of Fate/Zero as Kayneth's fiancée - and apparently one who does not get along with her intended husband. While Kayneth acts as Lancer's Master, Sola-Ui is revealed to be the one supplying the Servant with magical energy.
