Christmas is always a busy time for Chaldea. Not only are there presents and cakes to prepare, but also a new Santa to be selected. This year's Santa, bringing gifts of good health to all, is also just the one to rein the Servants running wild at the Rayshift site.
"Christmas needs a Santa, just as the ill need a nurse. And, of course, a Singularity requires you, Master."
A limited time Christmas event in Fate/Grand Order, released on the Japanese server on November 28, 2019 and on the NA server on December 14, 2021. Florence Nightingale (Santa) is given as a reward to players for completing the event.
