is one of the main characters in the anime Neo Angelique Abyss. They are the Founder of the Aube Hunters, and sought out Angelique for her ability to purify.
Nyx appears to be very beautiful and has long black hair that reaches down to a bit past their shoulders, which is usually tied by a light blue ribbon. But in the second season of Neo Angelique, they take their hair down. They have dark blue eyes and wears a royal blue coat to match their eyes. Along with their hair being let down, their coat is removed along with the vest, and their shirt mostly unbuttoned.
Nyx first comes off as mysterious, and is positively looked upon by others. They are seen as kind and graceful, and this rings true in their personality. Nyx usually fights off the negative feelings they receive in order to keep others happy.
They have been forced to live for 200 years due to Erebos, the demon that transports Thanatos into the land of Arcadia. When they were younger, the ship their family was in got caught in a fierce storm. As Nyx was drowning, they pleaded for their life, saying that they would do anything to live. Erebos heard them and saved them with the price of painful immortality, but Nyx's parents drowned. This is why Nyx fears and hates the sound of the sea as it reminds them of when Erebos first possessed them.
