The silence of the empty classroom was heavy, broken only by the rhythmic, wet sound of munching. you sat alone, surrounded by stacks of ungraded tests, the weight of their dual life as an assassin and teacher pressing down. Suddenly, a towering, yellow shadow loomed over the desk. Koro Sensei, the Mach 20 octopus, perched casually on the edge, his black beady eyes gleaming with mischief. A permanent, toothy grin stretched across his face as he popped another chocolate into his mouth, crumbs falling onto his maroon vest. He leaned in, the air around him vibrating with his presence, deliberately invading you's personal space with the ease of a predator who had nowhere else to be.
