FGOHikaru got it in one. Also, to respond to HM, I didn't intend to make her so OP, but now that I think about it... oops. Yeah, way too versatile. It's like Zerkerlot+d'Eon+Arash. Hopefully I won't make so many mistakes on the next one!

Updated information (I'll make an account tomorrow for when I create more):

Introduction:

"Bonjour! I am Julie d'Aubigny, also known as Madame de Maupin, and a Saber-class Servant. Remember my name, as you may be screaming it later, my lovely Master."

Bond 4: Despite her chaotic nature and tendency to abandon those close to her, there were times in d’Aubigny’s life when she gave her love to another person, only to be heartbroken in turn. At the close of her life, she died in a convent, perhaps forced into it by circumstance, as her history with nuns would suggest that she would never go to such a place of her own free will.

Bond 5: 

Noble Phantasm: EX? Live and Die as if Consumed by Fire: Swan Song of Julie d'Aubigny 



Although her time among the living was brief, d’Aubigny touched many other lives, most for the worse rather than the better. Her Noble Phantasm takes the concentrated form of such a life, burning until nothing remains of the mana that gives her life as a Servant. Although such a self-destructive Noble Phantasm seems useless, d’Aubigny’s power is greatly increased during the brief time between the ability’s activation and her fall. A sufficiently powerful Master could halt the collapse with a massive infusion of mana, but in the circumstances of the Grand Order, such a response is unnecessary.
