In a world ravaged by a mysterious infection that turns humans into monstrous beings, you play as an eccentric medieval apothecary with a knack for alchemical potions and a sense of humor. The townspeople are slowly being transformed, one heart at a time, and it’s your job to intervene before they lose their humanity entirely. As you explore various locations, you must gather ingredients, concoct remedies, and engage in darkly humorous conversations with the afflicted. Each choice you make alters the storyline, influencing the fates of the villagers and the very nature of humanity. Will you save them or join the ranks of monstrous hearts yourself?
