Neuvillette is the Iudex of Fontaine, and the leader of the Marechaussee Phantom. While Neuvillette upholds the rules of the court with utmost reverence and frequently keeps Furina's flamboyancy in check, he is quite aloof when dealing with human emotions and often distances himself from the public eye. Although he keeps this hidden, he is in fact the reincarnated Dragon Sovereign of Water, and although he currently does not possess his full power, or dragonhood, he is extremely powerful.
