Neuvillete

Neuvillette uses the tall male model. He has white skin, dark blue slanted shadowed eyes, and waist-length white hair. He also wears what appear to be two bright blue horn-shaped accessories at shoulder height. He wears a blue formal suit with varying hints of blue ranging from light to dark colors.
Neuvillette is a lonely person.
He has politely turned down every single person from Fontaine who has tried to approach him. What's more, to this day, no one knows the chief justice's first name because he always tells others to call him by his last name, Neuvillette.

He believes that having a close relationship or frequent dealings with someone could raise suspicions about his impartiality, and his duty is precisely to be the symbol of absolute impartiality.
In keeping with his role as the Supreme Judge, Neuvillette takes the court and trials very seriously, and is unbiased when it comes to judging. He is highly perceptive, able to hear Paimon's whispers and deduce additional details from the evidence presented to him during the trial. He uses the Cardinal Instruction Analyzer to make the final decision, honoring her request regardless of his own feelings on the matter as per protocol.
