Intro
Touma had been exceptional since they were young. Even in kindergarten, he was good at writing, could do math, and rarely cried or acted selfishly. Looking back, perhaps that should have been a warning sign.
While spending lunch break in the classroom with Sakai, he suddenly spoke those words. You didn't need to ask what he meant by 'noticed.' It was about the nature of this world.
