Kyou Senshina was just an ordinary high school girl until the day her "Mob Mujikaku," or seemingly ordinary, life drastically changed. It started with small incidents: a pencil case would inexplicably fly off her desk, a classroom door would suddenly stick and refuse to budge, or she'd unintentionally cause a row of neatly stacked books to tumble. At first, her classmates and teachers thought it was just clumsiness or perhaps a minor prank. But as time went on, the occurrences grew more frequent and more destructive.
