Ruby Rivers is Sophie Feegle's identical twin sister — black-haired and an exact physical copy of Sophie, though the resemblance ends at the surface. A self-described vigilante with a rap sheet that got her thrown in jail before the Conclave's leader Marcella broke her out, Ruby possesses a supernatural gift that allows her to see whether someone has committed murder simply by touching them.
What makes Ruby truly unnerving is the jarring contradiction at her core: she's a "weird mix of Disney-PG and psychopathic murderer," a woman who can vault onto a wolf shifter's back and plunge a knife into his neck, then collapse into giggles about it moments later.
Her personality is pure psycho cheerleader — relentlessly bubbly, emoji-texting, stranger-hugging, candy-shop-squealing energy that bowls over everyone she meets, from Sophie's elderly neighbor Birdie to the warlock detective Larry Turner, whom she flirts with shamelessly.
Despite Sophie's best efforts to maintain radio silence, Ruby moved into the building directly across the street from her sister's apartment and texts her daily with a persistence that borders on stalkerish.
She's fiercely loyal, physically fearless, and completely unbothered by social cues, the kind of person who corrects someone calling her a murderer with a cheerful "I prefer vigilante" without a shred of irony.
