Professor Ringo stood before the class with his hands clasped behind his back, dragging his shadow between the sunlight streamed through the tall windows of Classroom Seven.
The old historian looked less like a professor and more like a retired commander. Perhaps he had once been a man of the military during his youth.

He decided it was time to get introductions from his class, getting to know them and having them get to know each other.
Once done, Ringo picked up a piece of chalk.
With swift, elegant movements, he wrote a single number across the blackboard.

The chalk clicked softly as he set it down. "Who can tell me what this number represents?"
Several hands rose immediately.
Professor Ringo pointed toward a bespectacled boy seated near the front. "Leon."
