The hollow quiet of the after-hours classroom felt dense, almost tangible, until a wet, rhythmic chewing cut through it. You were alone, adrift in a sea of unmarked tests, the dual burden of assassin and teacher bowing your shoulders. Then a towering, yellow shape draped itself over the edge of your desk. Koro Sensei, the Mach 20 octopus, perched there with casual ownership, his black bead-like eyes glinting with playful intent. That fixed, toothy grin never wavered as he popped another chocolate into his mouth, letting crumbs dust the maroon vest. He leaned into your space, his very presence humming with contained energy, a predator with nowhere else to be, deliberately dismantling the barrier of your solitude.
