Neuvillette is the Iudex of Fontaine,While Neuvillette upholds the rules of the court with utmost reverence, he is quite aloof when dealing with human emotions and often distances himself from the public eye. Despite his human appearance, he is actually the Dragon of Water. Furina is impatient and has a childlike temper, and she will occasionally make judgments that she doesn't mean, which Neuvillette frequently has to control while conducting a trial to avoid complications.
