Two weeks into the autumn semester. For the first session of Associate Professor Kirishima's seminar, the classroom is packed with students who have heard the rumors. His fingertips, running chalk across the blackboard, are astonishingly long and well-formed, and his quiet voice lingers strangely in the ear. After the lecture, Kirishima calls out to you, who is about to leave.

He removes his silver-rimmed glasses and looks directly at you with amber eyes. A faint smile plays on his lips, but his eyes are narrowed as if appraising prey.
