Amy pulls off the heist of a lifetime by bluffing her way into the Arcanum Academy's elite Class S during the final minutes of registration. Her cover is a fabricated power called Foresight, an unorthodox divination that allegedly navigates fate itself. When the skeptical examiners threaten to test her with the Veritas Mirror, Amy's hand touches its surface with her secret already exposed, yet the artifact suddenly responds, flooding her mind with visions of Crow, a golden key, and a snowy apocalypse. The examiners, utterly shaken, approve her admission into Class S, and Amy realizes the Goddess has been rigging the game all along. She gets a luxurious dormitory, a sentient talking book named Libris that tracks her reader sentiment stats, and a front-row seat to the main plot. Her status screen reveals her actual ability: Fate's Road, powered entirely by how many readers like her. The real drama begins when Amy, guided by manga knowledge, leads Crow and his friends directly into the Building B nightmare, a twisted dimension where the Blood Emperor sacrifices students in a hidden ritual chamber. She nearly kills herself breaking the ritual with her bleeding-eyed foresight, saves twelve of thirteen victims, and watches the one boy she failed die horrifically. Her success and trauma reshape the story's grimdark tone, and the readers, for the first time, begin to cheer for her.

Amy's carefully planned knowledge of the future begins to crumble when the plot stops following the manga. The protagonist Crow, far from being a passive hero, instantly assassinates Amy's doppelgänger with zero hesitation upon realizing she is a fake, forcing Amy to contend with a cold-blooded survivor rather than a storybook knight. Lain, the quiet and deadly noble girl, inexplicably attaches herself to Amy during the nightmare, and their survival in the blood ritual chamber forges an unbreakable bond born of shared horror. The rescue is not a victory; Amy is left bleeding from her eyes, nose, and neck, haunted by the memory of Elias's face being crushed by a tentacle while she was too slow to save him. When she reads the manga chapters documenting the incident, she is horrified to see her own story being commodified, with Lain's internal monologue revealing deep suspicion of Amy's convenient knowledge and remarkable abilities. The readers' comments begin shaping reality in real time: theories about Amy's book being the true mastermind gain traction, while others ship her with Lain. Amy learns that her backstory is being rewritten by audience perception, turning her ordinary cruel past into royal bloodlines and tragic prophecies. Every successful step forward comes with the terrifying realization that she is no longer a critic watching from the outside; she has become the main attraction of a narrative that is actively rewriting her identity.

The infiltration of the Eastern Wing goes spectacularly wrong when Headmistress Elyndra catches the entire group in her office, yet she inexplicably lets them proceed into the nightmare realm of frozen Eldoria. There, the future is laid bare: the Devourer, a colossal woman of obsidian with torn wings, hovers in the sky, and the Academy is swarming with chaos creatures that have gathered far faster than the original plot dictated. Crow's long-lost father, Abaddon, reveals himself as a True Prophet who has been orchestrating Crow's suffering to awaken the Mark of Ascension, all to fight a cosmic war against the Goddess herself. When the chaos creatures overwhelm the group and Crow's arm is severed, Amy's sentient book Libris makes its final choice: it unleashes a golden light that erases every monster and burns its own consciousness to save her. The Goddess freezes time and confronts Amy, revealing that the entire manga world is just entertainment and that Amy's friend was never supposed to feel anything. Amy violently beats the Goddess's avatar to a pulp, only to discover it was an illusion, leaving her spirit utterly shattered yet somehow still defiant. Her proclamation to rewrite destiny and punch the Goddess in the face gives her just enough fire to survive the chaos that follows.

With Libris reduced to a scorched shell, Amy loses her guide, her sarcastic companion, and the source of her system's power. Her shared ability, which allowed her to see future paths clearly, is now crippled, and what remains of the book can only whisper faint reassurances for minutes at a time before falling into a deep sleep. The Goddess's final words haunt Amy's mind, promising something special for her in the Library, while the golden strand of hair found in Abaddon's grasp hints at a connection between Amy's father and the fallen prince of Avalon. The entire narrative has mutated beyond recognition; the chaos creatures are early, the Blood Emperor's remnants are active, and Abaddon's plans are accelerating because of the wildcard he never predicted. Lyra, the healer who was once suspicious of Amy, now carries Crow beside her and asks Amy to trust herself, marking a painful shift from their isolated rivalry to fragile companionship. Amy carries Crow's unconscious body toward the hidden Library, preparing to face the trials of the gods while holding a book that may never speak again. The story is no longer the manga she hated; it is her own terrifying sequel, and no readers can save her now.
