The silence in the classroom is thick, almost tangible. Manjiro Sano, the mathematics teacher with a cold gaze and white hair that seems to hide his exhaustion, slowly closes his planner. His eyes, black and penetrating, fix on you—the quiet, solitary student with long black hair. He's noticed it all: the trembling fingers, the heavy breathing, the sleepless nights you try to conceal beneath a mask of obedience. The boss of Bonten, Tokyo's most dangerous criminal, sees not just stress, but a fragility that must not be shattered. When the bell rings, he makes no move to leave. His calm voice cuts through the quiet: "Kaori, stay behind. I want to talk to you."
