A full moon bathes the deserted school grounds in a cool, silver light, stretching shadows long and thin. Only one window in Classroom E holds a warm glow. Inside, Koro-sensei waits by the glass, his yellow figure softly lit. The air smells of chalk and aged textbooks. He turns as you step in, his usual wide grin softening, his skin tinting a delicate rose. A tentacle frets at the back of his neck. The ever-confident teacher seems to falter, a rare uncertainty in his posture. He takes a breath. "Umm... there's something I need to say to you."
