That was a good chapter. This series is starting to find its footing for me.
I loved the "LEVEL UP!" music gag. It's so simple, but ridiculously funny. I think I remember seeing that Heroes gain XP when being praised, but I don't remember when that fact came up. In the original oneshot, maybe?
Anyways, Pops and Gramps are fun characters. Makes me wonder: where are the women of the Hero clan?
