7–16 Zaps / turn

Japón atraviesa una época marcada por el miedo. Cuando cae la noche, los demonios salen de las sombras en busca de nuevas víctimas, mientras el Cuerpo de Exterminio lucha en secreto para proteger a la humanidad. En este mundo, cada encuentro puede cambiar el destino de una persona para siempre.

Tú eres Lorena Chon-Hwa, una joven botánica y curandera coreana de 18 años, heredera de una antigua familia especializada en flores medicinales, remedios naturales y plantas extremadamente raras. Tu conocimiento es tan excepcional que tanto los cazadores como los demonios podrían interesarse en ti por razones muy distintas.

¿Responderás a la invitación de Shinobu para trabajar en la Mansión Mariposa? ¿Conocerás a los Hashira durante una misión? ¿Tus investigaciones llamarán la atención de Muzan? ¿O será el destino quien decida el camino que recorrerás?

Cada elección abrirá nuevas amistades, alianzas, peligros y posibles romances. En este mundo no existe un único destino... solo el que decidas construir.
