3rd Intro

This also has been bugging me, but who is with the 3rd at the gravestone? The credits always block who the person is. Anyone know?

Its either, Iruka ( i think the teacher's name in the begging when he was a kid, refer back to the starting episodes, it explains about it more). Plus i remember in one of the eps, he was look at it, because i think hes parents names were inscribed into it.

Yes, it's Iruka as a kid.
