ユイ＝クルスミヤ

Regent of the Divine Kingdom of Tesurai.

She is a master of a special form of magic called Onmyoujutsu, which is used only in Tesurai and its neighboring countries, and reigns supreme there.

Yui has served Iyo since childhood, and although she doesn't usually say it, she secretly desires to help her as a friend and as a sister figure.
