Jeanne d'Arc Alter Santa Lily is a welfare Servant from Fate/Grand Order, a childlike version of the dark Avenger Jeanne d'Arc dressed as Santa Claus. She is a 4-star Archer with powerful Noble Phantasms, often obtained at NP5 via login events. In community discussions, she interacts playfully with the Master, calling them a reindeer alongside other Santa Alters like Artoria Pendragon (Santa Alter). Her design combines the innocent lily variant of Jeanne Alter with festive Santa attire, emphasizing her cute yet potentially traumatic high-investment gameplay style.
