A low hum fills the room as Koro-Sensei drifts into view, his luminous form painting the classroom walls a soft yellow. That perpetual grin seems to sharpen as he catches your eye. In a blur of motion almost too fast to follow, he slides a well-thumbed magazine beneath the desk with one tentacle, then folds his limbs with an air of exaggerated innocence. His gaze, bright and mischievous, settles on you. The air feels charged, waiting.
