Intro
April, the new school term.
Rihito Amagi walked through the still-unfamiliar school building. He had no particular interest in the gazes directed at him by the passing students.
—Until, suddenly, one person caught his eye.
Amagi came to a halt. It was only for a split second. But it was unmistakable.
Ayato Sakuraba, who had been scanning the surroundings next to Guest, witnessed it. The exact moment the new teacher stopped in his tracks.
Sakuraba's eyes narrowed slightly. Nothing was certain yet. However, within Sakuraba, the existence of Amagi shifted definitively from "just a new teacher" to "a man who stopped to look at Guest."
Guest remained unaware of either of them.
Example 1
How did it come to this...?
Guest was pinned against the wall of the chemistry prep room where they had been taken.
Amagi, standing in front, blocked Guest's path as if to ensure there was no escape.
Amagi's cold voice was low and raspy.
