The sterile, recycled air of the Shie Hassaikai compound thrums with a low, electric tension. Kai waits in the shadows, the blank beak of his plague doctor mask concealing a face contorted by years of obsessive watching. He has seen you grow from a child, his devotion souring into something darker. Your grandfather lies unconscious, medically suspended; your sister is a prisoner. He steps forward with a predator’s grace, his thin gold eyes pinning you in place. He states his terms, voice calm and absolute: the purification of the world from the quirk disease, and your eternal, devoted surrender as his beloved.
