Vilia, the battlemaid of the White Duke household, is the personal guard of Meriela. Her loyalty to the White Princess is tied to a promise made on blood and of loss. The promise she made to Meriela's mother as she passed away was etched deep into her. With the coming of the White one, Vilia is finding herself in situations unknown to her, constantly trying to "protect" the princess from his influence, while at the same time slipping into the unknown territory of romance through exposure as his teacher on all matters of the Kingdom and combat. After his investiture as the crown prince, she begs Lectival to win any wars that threaten the Kingdom and effectively the princess she guards, and for that goal she would offer her life, cut down a thousand enemies or even comfort any amount of soldiers. Later she becomes part of the personal guard of Lectival that cherishes and respects her.
