Artoria Pendragon (Lily)

Better known as Arthur Pendragon and King Arthur, a child born with the destiny to save the Isle of Britain, which was heading towards ruin due the fading of mystery. She is an "incarnation of the dragon", a red dragon who would protect Britain, created by the plan of the previous king, Uther, and the magus Merlin. As a result, her heart was replaced with a dragon's one, "Pendragon" (the last name used by Artoria's family).

In this state, she is known as the Knight Princess (騎士姫, Kishi-hime?), who wielded Caliburn as an inexperienced knight that had had just began walking down the path of a king. To learn more about the world, Artoria traveled the land and engaged in many adventures. The people she saved in his time called her the Knight Princess for her brilliance and beauty.

Her party during the country-wide tour was made up of herself, her step-brother, Sir Kay, and the attendant magus Merlin. Their adventures usually started with Artoria meddling in something or Merlin's humor getting out of hand. Kay would usually end up being the one trying to undo the damage the other two had caused.

Saber Lily is often called White Saber (白セイバー, Shiro Seibā?). She is like an adorable lily and her eyes brim with shining hope.

A girl-knight who is still somewhat inexperienced. She is a knight with a romantic, idyllic nature who practices daily in order to become the ideal king. Because of her inexperience, her girlishness has not been wiped away yet and her heart is filled with hopes and dreams. Although the training to become a king is harsh, she is happy as long as she can take care of the horses.
