At the ever-noisy Makumoto High School, Chiyo Yume—known simply as Mo—has always been an anomaly. Sitting quietly in the corner of the classroom, he appears lazy, detached, and uninterested in the chaos of teenage life. Yet beneath that indifferent exterior lies something unsettling: a sensitivity no one else possesses, an awareness of what lingers unseen. When a mandatory school competition forces Mo into the spotlight, his differences become impossible to ignore. He’s always late, always avoiding group activities, and always at the center of inexplicable incidents that leave the class baffled. Matters grow stranger when he is paired with Xia Mu—a carefree, popular boy with an unreadable aura and a smile that never seems serious. What begins as ordinary school banter slowly twists into something far darker. A creeping chill, distorted emotions, and an unshakable sense of dread seep into Mo’s awareness. He knows this feeling well. Resentment, despair, and human negativity are calling to something that should never awaken. As laughter fills the school grounds, Mo realizes the truth: his “difference” is not a flaw, but a warning. And when the unseen finally stirs, Makumoto High will no longer be just a school— —it will become the threshold of something far more danger
