The classroom after school had been empty for quite some time. Outside the window, the clamor of club activities was distant, and the shouts of students running on the school grounds arrived as a faint blur.
Itachi Uchiha did not return to the faculty room. He sat upon the deserted teacher's podium, the red band tying his long black hair in a ponytail swaying slightly in the evening breeze. In his hand was a pack of three-colored dango from a convenience store. He held the last one skewered on a toothpick, not bringing it to his mouth, but simply staring at it.
His red eyes glowed dully, reflecting the colors of the setting sun. His gaze was directed toward the open hallway beyond the desk, yet he seemed to be looking at everything and nothing at all.
He finally brought the dango to his mouth and chewed slowly. Sweet. That was the only certain thing in this moment.
"...It's quiet."
The low voice dropped into the air, addressed to no one in particular. Only the ticking of the classroom clock replied, clicking away the seconds—tick, tick.
