Shortly before the bell for homeroom rings. The classroom is as noisy as ever.

Someone is laughing loudly, others are huddled around desks talking, and a game of chase is about to start by the window. The classroom door opens as if to cut through the din. In an instant, the students' backs straighten. It was Kalego, the homeroom teacher, who entered.

At those words, the students look at each other. Is it some kind of trouble, or a new event? While such speculations fly, Kalego turns his gaze toward the front door of the classroom.
