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.

Sola-Ui openly calls Kayneth a coward for not facing the other Masters face-to-face, and criticizes his tactics when commanding Lancer in battle. However, she is chastised by Lancer, who resents her reprimanding of his Master, and immediately backs down. Kayneth in turn views her apparent submission to Lancer as evidence of her developing affections for the Servant.
