Klein Gremory

Klein generally comes across as serious and protective of Eve, but it is later revealed that he had quite a wild youth, filled with gambling, fine wine, and easy women. He regrets his past mistakes, however, and looks to guide Eve as best as she can. In spite of his polite and almost regal manner of speech, many of Klein's quirks are very cat-like in nature. This includes his love for wet food and fish, constant grooming, and dislike of water.

He was shown to be disdainful of Nyx's relationship with Eve Xin, their former Conjurer, due to the latter being human. Regardless of his viewpoint, Klein truly did care about his old Conjurer but was too prideful to admit it until the very last second. As of becoming pact partners with Nyx once more via Eve Staccato, Klein desperately tries to atone for his past actions despite Nyx's hostility towards him. Klein has shown that he wants to make things right, but he's not one to take risks until Eve pushes him to try.

Klein is a black and white Cat Sith with green eyes, paw pads, and inner ears. He wears a dark green capelet and a bell sewn to the middle by his past Conjurer. He has two tails, like all Cat Sith. Apparently, according to a statement by Nyx, Klein appears "chunky" in this form.

In his human form, Klein is much taller, with shaggy black hair and two ear-shaped tufts on the top of his head. He retains the cowlicks he had as a Cat Sith. He has a white streak on the left side of his bangs. In this form, Klein wears a grey military uniform with white buttons and a green belt around the middle. He wears back pants tucked into white boots that have dark green trim. His capelet is much fancier in this form, with gold trims and a chain holding both sides together. He also sports a pair of white gloves.
