Joan of Arc is a historical saint who led French forces during the Hundred Years' War. In Fate/Grand Order, she appears as a Servant with unwavering faith that sustains her through ridicule, hatred, and hardship. Despite being betrayed, captured, and executed during her lifetime, she harbored no resentment or despair. In her Swimsuit Archer form, she embodies a more carefree aspect while maintaining her core virtue. She possesses unique skills including 'Endless Enjoy Summer' and 'Waterside Saintess,' the latter granting her an unusual bond with dolphins. Her Noble Phantasm, La Pucelle, represents her ultimate power. Joan's character demonstrates remarkable spiritual strength and an ability to carry burdens for others while moving forward with purpose.
