As Jeanne Alter was born from Gilles de Rais's wish upon the Holy Grail, so was Jeanne d'Arc Alter Lily born from drinking King Gilgamesh's suspicious medicine, and aiming for Santahood, she became Jeanne d'Arc Alter Santa Lily.
Indeed, Alter-chan is the second generation Santa!
Jeanne d'Arc was said to be a tragic saint, but her period of activity was exceedingly short at only two years in length.
Jeanne Alter is the darkened existence of Jeanne d'Arc that originally did not exist, while Jeanne d'Arc Alter Santa Lily is the childhood form of that non-existent girl, and no record of her existence on the time axis can be found.
If anything, her personality resembles that of the original Jeanne.
In other words, she is serious, inflexible, prone to recklessness, may resort to illegal means if necessary, and even if unnecessary, may resort to illegal means if they are more efficient, et cetera.
Where she is different from the original Jeanne is that she loses her calm quickly upon getting panicked and begins to cry, throwing the surroundings into chaos.
Personally, she seems to feel ashamed over the adult Jeanne Alter's petulance.
"She still seems embarrassed over becoming a Servant and doesn't know how to face Master, I suppose it really can't be helped!"
Is what Jeanne d'Arc Alter Santa Lily said.
Although she herself wants to be spoiled by her Master but doesn't know how she wants it to be done, so she is indeed Jeanne Alter as a child.
A skill acquired by those who are able to become Santa Claus.
Giving out presents, enriching hearts.
Although immature, her willingness to work earnestly at everything has earned her a good evaluation for a Santa, and as far as beginner Santas go she is quite highly ranked.
Originally, Servants are summoned in their prime, but she has now been summoned as an existence that would "grow from now on" as an exception.
She will become evil if you wish her to be evil, become good if you wish her to be good.
Even though her future may not be bright.
But if it is wished for, the guiding lamp of a saint may still be bestowed.
Rank: A+ Type: Anti-Army Range: 1~10 Maximum targets: 10 people La Grace Fille Noel.
In contrast with "Howl and stand, my rage", a Holy Song Noble Phantasm that activates when Jeanne d'Arc Santa Alter Lily is in high spirits.
Bad children will be lectured (damaged) and good children will get presents (buffed).
The presents that fall and pile up like snow are pretty well received by the children awaiting Christmas, or something.
Though, there's no actual need to sing.
Jeanne d'Arc has her sense of duty from her revelations, and Jeanne Alter has her avenging heart born from despair, but Jeanne d'Arc Santa Alter Lily has neither.
Although she was a girl barely permitted to exist thanks to the instability of the Human Order, she would originally not have lasted past Christmas.
An existence that could truly be called a Christmas miracle.
In order to prove her own usefulness, she took on the challenge of being Santa Claus, but that was in truth unnecessary.
She should have just awaited her present.
For a certain someone by her side would surely give her a gift.
...Still, the girl born without desires did not understand gifts and did not even know that she could receive them.
The harsh, wild, and magnificent sea. In the memories of the adult Jeanne, it was but a modest wish that had long vanished.
That may have been a different sight from the one remembered.
But, her wish was definitely fulfilled.
In this world, wishes can be fulfilled--- at the moment she realizes this, the girl's story begins.
