Main

 * Rei Spookmoore (voiced by Hynden Walch) - a friendly and optimistic ghost teenager girl who tries to make friends although her attempts sometimes backfire.

Rei's Friend Group

 * Joey Strange (voiced by Joshua Rush) - a friendly and cool-headed, but mischievous and somewhat punkish warlock teenage boy who is Rei's best friend, later getting in a relationship with her.
 * Lucien (voiced by Dave Willis) - a smooth-talking, eccentric, well-meaning, and laid back demonic familiar with a Brooklyn accent who is Joey's guide/conscience as he tries to advise Joey the best he can, as he is also quite fond of Rei and the others.
 * Billy and Billie Frankenstein (voiced by Max Mittelman and Ashly Burch respectively) - a duo of twin mad teenage scientists who are Dr. Victor Frankesntein's children, forced to go to Spook Academy following their dad's death despite being normal humans, although they end up befriending Rei. Billy is the comedic and witty brother, while Billie is the serious, snarky, but somewhat seductive and pretty caring sister.
 * Gerald "Globby" Christensen (voiced by Richard Steven Horvitz) - a socially awkward and anxious glob who befriends Rei even if he can get paranoid real easily.
 * Maddie Edmonds (voiced by Jennifer Hale) - a disembodied head who is one of Rei's other best friends as she is snarky, pessimistic, and sometimes cynical as she is focused mainly on the cold hard facts.
 * Camryn "Cammy" Crystal (voiced by Eden Riegel) - an optimistic, peppy, and seductive, but clumsy and sometimes oblivious teenage cyclops girl with a thing for fashion, usually convincing Rei and the others to try some of clothes from her fashion brand, while also having a BFF-type relationship with Rei and Billie.
 * Brenda Morgan (voiced by Liliana Mumy) - a shy and friendly teenage banshee girl who has trouble talking to others, but was easily able to warm up to Rei and looks up to her.
