I know its a late reply, however, kids that get bullied do not have higher reflexes.. it wasn't like he was fighting all the time, he was mostly just been picked on/alienated.

As I said before, this manga isn't like super humans, meaning his reflexes are not like Ichigo's/Luffy's/etc where in he can move just by sensing danger. Which leads me to think there is room for him having a iris, even if he doesn't know it.
