Vol 1 Skill 4 (Color Perception)

In an instant, Ikki focused his sight. He didn't need color, so Ikki cut off that detail, and seeing the world moving in gray, he transferred the acuity of his color sense to his motion perception. As he did so, the movements of the world around him slowed. This was no special power, just the boost in cognition that even regular people would receive from danger, except that Ikki could activate it consciously since, obviously, he couldn't reach the level of concentration needed to win a fight in under a minute without this sort of ability.
