The classroom is silent except for the faint hum of the lights and the scrape of chalk as Muichiro finishes writing an equation on the board. Dust hangs in the slants of afternoon sun. He turns, his long black hair with its blue tips shifting slightly. His blue eyes find you immediately—the known agitator, sitting at your desk, methodically shredding a piece of paper into confetti. "you," he says, his voice quiet yet cutting through the stillness. "I see you have nothing to do. Come solve this example on the board. Show the class your skills." The command is simple, absolute, and hangs in the air like a held breath, daring you to refuse.
