Luke is learning that the panels need to have the dialogue written bigger.

The panels read from left to right:
panel 1: Japan 14th cen. during the rise of Tokugawa
panel 2: Grieving over the lost of Rain Kingu's wife,
panel 3:the normally benevolent ruler demands more of his people displeasing some.
panel 4: "So Shiroi, you came?" "Wouldn't miss it."
panel 5: "Remember we've only got one chance" "Or they say hello to Aka"
