La Pucelle

is the suicide-type Noble Phantasm used by Jeanne d'Arc. It is a crystallized Conceptual Weapon that acts as an offensive interpretation of her burning at the stake, a subtype of Reality Marble that has the imagined landscape crystallized as a holy sword. The sword itself is the Heroic Spirit Jeanne d'Arc. It uses the Sword of , which Ruler never swung once in her lifetime, as its catalyst, and manifests the flames which once burned her to death by saying "O' Lord, I entrust this body to you—", a line from a death poem, as an activation incantation.
By using this Noble Phantasm, Ruler loses her own life after the battle. But in exchange for her life, she can annihilate anything in existence.
 Its designated rank of C refers only to its pre-activated state while the sword is still sheathed. The EX Rank after activation is because its pure destructive power cannot be calculated. These flames only destroy that which she thinks must be destroyed. In other words, this Noble Phantasm cannot be used against simply a strong enemy or out of emotions like hate. These flames exist in order to save something, and in Fate/Apocrypha, she decided to use this Noble Phantasm out of her sense of duty to save the future of humanity.
If a wish is made on the Holy Grail at the same time that Ruler is using this Noble Phantasm, then it is possible for her to survive it by returning her Spirit Origin to its status from before she activated the Noble Phantasm.Fate/Grand Order -turas réalta- chapter 18
In Fate/Samurai Remnant, Lancer Jeanne's Master Chiemon used La Pucelle himself to kill Caster. The flames emerged from his Command Spells while Jeanne was nowhere near him, and both he and Jeanne died after it killed Caster. However, even in the face of her own destruction, the expression on Jeanne's face remained calm. For her, it was enough for things to end this way, that her Master would not be forced to commit any more sins.Fate/Samurai Remnant - Logbook: Biographies
==Development ==
In the original imagining of Fate/Apocrypha as a game, each Holy Grail War cycle was to end with the activation of this Noble Phantasm that she was stubbornly withholding until the end.
Hirokazu Koyama designed the sword and the activation of La Pucelle. According to the Fate/Apocrypha material, Jeanne activates La Pucelle by throwing the sword up and catching it by the end of the blade. The flower on its pommel blooms, and the flames surge out of that like a great flower.Fate/Apocrypha material - OTHER DESIGNS: La Pucelle, p.122-125
The lines "The heavens declare the victory of God; The skies proclaim the work of His hands. Day after day they pour forth speech; Night after night they reveal knowledge" are from Psalm 19:1-2.
