Creation and Conception
Known as the Stray Servant (はぐれ サーヴァント), Shielder was a heroine candidate during the development of Fate/stay night who was left unused in the final version. She was considered along with Rider and Caster to be a possible heroine, but she was cut due to the plot beginning to stray so as to keep it manageable for the player. As Saber is a "Servant of the Sword", she was to be her rival as a Shielder, "Servant of the Shield." She would have been an "abandoned puppy" type heroine who killed her Master during the Fourth Holy Grail War and went on a rampage, surviving into the Fifth Holy Grail War in a similar manner to Gilgamesh.

Her role was originally only detailed in Fate/side material, but it was planned that she would be a character in what was to be the original story of 's Fate/stay night adaptation. Her character design by Takashi Takeuchi was completed at that time, but the anime was later changed to an adaptation of the Fate route and the character was again abandoned. The design was later revived for Grand Order for Kinoko Nasu to allow her to be one of the main heroines along with Saber and Ruler.
