Kora is a salon owner who appears in "Essence".
Kora managed to learn how to drain essence from people, and so created her own beauty salon with products infused with the essence of her own workers, leaving her VIP customers with a refreshing glow. Whenever one of her workers died from this draining, she learned to eat their corpses (choice organs of them) in order to sustain her own youth, health, and beauty indefinitely. By the time of the events of "Essence", her real form was that of an elderly woman with opaque, failing eyes, but could revivify herself to that of a beautiful, matronly woman through the consumption of her workers' organs.
One day a worker of hers, Mina, is set to be fired by Jessica. Kora intervenes to save her job, having received a glowing review from an internet celebrity with millions of followers, praising the salon and Mina's work. Kora offers her on-premises housing with Tran after Mina's assurance that she won't go outside of protocol again. Later, in the break room, Kora affectionately cleans up Mina's face with makeup before leaving again.
One night, Kora goes to produce more VIP product and to revivify herself, only to be caught by Mina, taking a picture of her in the act. Kora is unperturbed, offering Mina a chance to join her and to be wealthy forever, but Mina sends the picture to Tran just before she collapses. It is strongly implied that Kora then ate Mina and administered some of her organs to Tran to revive her as well. The next day, Kora offers to rehire Tran with a 15% raise, to which she reluctantly agrees. However, as she leaves, Tran discovers her methods and then kidnaps Kora, leaving her imprisoned in the back of the salon, being drained to produce VIP product just as she herself drained her workers.
