Yuka Hidaka, Airi Suzuki, attends school with Hinako Kurohane, Miyabi Natsuyaki, a brilliant student who is nonetheless treated as a social outcast. Hinako’s quiet world is marked by a troubling family dynamic: her parents neglect her in favor of her younger sister Kana, even as Hinako’s grades remain the envy of her peers. The story follows a stark contrast between the surface of academic success and the darker currents running beneath, as Hinako discovers she has cancer and faces a cold response from the people closest to her. Her mother’s indifference deepens her isolation, planting the seeds for the dramatic choices that follow.
Hinako’s sense of grievance grows as she confronts both her illness and the way she’s perceived by others. In a cruel turn, she curses Kana, and Kana’s health deteriorates rapidly, dying within a month. Hinako then tries to curse her mother, but the attempt falters, pushing her toward a different path: she enters a school festival competition to sharpen her skills, hoping to gain power or control over the life she feels slipping away. The shift from personal misfortune to a calculated, dark ambition marks a turning point in her life.
At school, the cruelty she endures from classmates intensifies. Led by the class president Sonoda Shiori, the students target Hinako with persistent bullying, turning daily interactions into a source of fear and pain. Hinako seizes a chance to react when she is chosen to write a script for the school festival play. She begins to curse her classmates one by one as part of her increasingly dangerous experiments with power. The only person who seems to understand what is happening, at least at first, is Yuka, who notices something is seriously wrong. The tension between Hinako’s growing掌握 of dark influence and Yuka’s concern sets the stage for a fateful confrontation, and the tension between belonging and exclusion reaches a breaking point.
As the curses deepen, Sonoda Shiori discovers what Hinako has unleashed. Whose attention Hinako’s actions have drawn becomes crucial: Sonoda realizes the danger but is too close to the effects of the curse to remain safe. She confronts Hinako, and in a desperate turn of events, Sonoda attempts to kill her, only to find herself drawn into Hinako’s web. Sonoda transfers to another school, only to reappear days later with the intent to end Hinako’s threat. The two clash again, and Sonoda’s life ends in tragedy, not solely by her own hand but because she becomes a victim of Hinako’s curse. With each new act, the curse grows stronger, manifesting through a troubling new channel: text messages. Hinako’s words begin to circulate through messages, amplifying fear and danger, even reaching Yuka, though she never reads the message that might have warned her.
Time passes, and Yuka finds herself recounting the legend of Hinako to a new group of classmates. The tale becomes a communal story, but the spread of the curse accelerates as the group steals Yuka’s phone and discovers the actual textual warnings that Hinako sent, including one directed at Yuka herself. One by one, Yuka’s new classmates die, leaving her isolated and increasingly desperate. The realization hits hard: the only way to survive might be to widen the circle of readers who encounter Hinako’s words, spreading the curse further rather than containing it.
Desperation drives Yuka to take drastic action. She begins to kill people randomly and, in a bid for control, crafts a short story woven with Hinako’s lines and posts it online. By publishing the story, she extends her own time to live, hoping that more readers will inherit Hinako’s burden and, in a perverse way, keep her alive longer. The narrative becomes a perilous chain: the more lives she touches, the longer she survives, yet the danger deepens for everyone who encounters Hinako’s curse through the messages, the stories, and the words that won’t stay silent.
In this somber, slow-burning thriller, the line between power and peril blurs as a girl’s desperate longing for belonging spirals into a deadly web that drags in friends, strangers, and the very idea of connection itself. The story asks how far one might go to be seen, and at what cost that visibility comes, leaving readers with a haunting question about the reach of words and the consequences they carry.
