Black Peter makes a rather innocuous first appearance in the 4th lesson. By now we are already familiar with Nami, the lisping Oriental girl (who possibly poses as Japanese in some chapters of this epic Elementary school saga) and Joon, a child (perhaps Korean, like Jinho, our hero, or perhaps simply a figment of our imaginations) with pencilled in freckles and the over-familiar manners of a man with connections. See how he sinisterly grabs the poor child's shoulder as he ferries him toward the enclosed space... Already there are twinges of unease in the portrayal of Black Peter, but it is all innocent enough at this point in Lesson 4. Joon is a sick little bastard, though.
