A woman once known as Herodias (ヘロディアス?), wife of Herod II and mother of Salome. She was a woman cursed to live forever because she laughed at Christ's pain when He was crucified. Kundry's immortality takes the form of her constantly reincarnating with her memories intact. Once, she had been a Witch; once, the consort of King Herod II. It was even said that she was once a Valkyrie.
During the time of King Arthur Kundry served Klingsor. Her enchanting kiss enthralled even the lord of the Grail Castle. She was an enemy in Percival's search for the Holy Spear of Lucius Longinus, which was part of his quest for the Holy Grail. She was Percival's first kiss, but he was able to resist the magic in her lips and went on to confront Klingsor.
After Percival defeated Klingsor and Klingsor's fortress began to vanish into light, around the throne were blooming flowers. Percival wondered if they were Kundry's act of consolation to the wicked mage who longed for what was holy but was never able to love it.
It is her fate to serve men of strength in every life, only to be used as a tool and cast aside. That fate will never end until she is at last united with her true love, Percival the Holy Knight of the Dove, and granted the salvation of death.
Kundry wears a habit and veil. Her clothing is stitched with horsehair, said to be worn by those who wished for atonement. She has black hair and walnut skin. The lids of her rich, dark eyes are lowered, as though she were half asleep. She has captivating lips, and her face, near-flawless in its beauty, proudly shows her Mediterranean heritage. Once her hair is freed of her veil, it dances proud and wild.
Kundry's clothes were torn apart in her fight with Erice Utsumi to the point it could be called "scandalous", but she looked like a virtuous woman of the cloth before then.
Kundry is described as a mad queen, and shows obvious signs of being unhinged. Kundry will never tell a lie, but nor will she ever serve the side of good. She falls madly in love with the man she decides is her lover, such as Hendrik van der Decken, and refuses to listen when others try to convince her otherwise.
Kundry arrived in Akihabara pursuing Hendrik van der Decken, a Servant whom she had decided was her lover. Erice Utsumi, a defender of Akihabara who hunts Servants that break the rules of the Holy Grail, recognized Kundry as a threat because if let alone she would begin to feed on the life energy of innocent people in order to sustain herself. A fight between Erice and Kundry deprived Kundry of her mount.
Erice escorted Hendrik and his Master Ahasuerus out of Akihabara in an attempt to get Kundry to leave as well. Kundry had pursued them with her summoned gremlin familiars and fallen into despair when they left. Unwilling to leave the city herself, she pierced Erice with the Holy Spear and then vanished. As Kundry's Saint Graph was falling apart from their fight, Erice wondered if she would make it very far before disappearing.
Being a Rider, Kundry has a mount of some sort but Erice Utsumi deprived her of it with a trap. As a former Valkyrie, she is very skilled with the spear, and she is also skilled at magecraft. She is capable of using Projection magecraft to create the Holy Spear Longinus. Erice initially mistakes it for her Noble Phantasm before realizing it's a Projection.
Since she doesn't have a Master, Kundry regularly attacks people and drains their magical energy to sustain herself.
She is described as being cursed with immortality, but in a way that she would wander from world to world by reincarnating while keeping her memories until she would find her one true love. Because of this unique sort of immortality, Kundry as a Servant can remember individual summonings unlike how most Servants forget each time they are summoned.
