A fortune teller named Kazumi Obai runs a notoriously difficult-to-book salon known as the Obai-ke Mirai Annaijo, or Future Guidance Office. She possesses the power of future sight. Clients who manage to secure an appointment come seeking a glimpse of the future they desire, and she guides them toward that envisioned outcome. However, the series is a psycho-horror that explores the unsettling gap between what clients wish for and what genuine happiness actually means. The true horror lies not in a wish going unfulfilled, but in a twisted wish being granted perfectly, exactly as the client imagines it. Each visitor brings a personal conflict—such as a high school student in love with her teacher—and Kazumi uses her clairvoyance to navigate the infinite branches of possibility. Yet seeing the future is a lonely and hollow gift. Despite the emotional weight, she continues to engage with others and unravel their futures, driven by a private, deeply held attachment. The narrative unfolds in a series of episodic cases that together form a complete story arc, examining the depths of human desire and the unforeseen consequences of having one's darkest hopes come true.
