Nyx

Nyx (official name Nix) is part of Pluto's rag-tag antics group and the only one that Charon cares about.

Personality
Nix is shy and introverted, preferring to stay inside whether it be any sort of weather, good or bad. Nix does not like her name being written as "Nix", and prefers "Nyx" as a nickname. She also seems to look up to Charon as trustable despite Kerberos's dislike and what Styx thinks of Charon.

Nix seems to use shorter words, and gets more easily confused seeing longer words (e.x. preferring "Alright" over words like "Pleasant" or "Satisfactory").

Appearance
Nix/Nyx/Nicks/Nimcompoop seems to wear a crimson turtleneck with a black coat over it, which gives a "fancy" look. Nix rarely wears anything besides this, save for the black coat being removed in favor of just a sweater.

In some cases where she needs to wear at least something besides the sweater, she dons a bowler hat.

House Appearance
Nix does not have a house, instead preferring to live with Charon.
