In this chapter, we learn that Hiroshi and his friends are studying together. Hiroshi asks if he can study with them, but they refuse, saying that he's too stupid to do so. He's also worried that they'll find out that he doesn't know a thing about history. He wants to know what happened to the emperor in 1221, the anti-child rape act in 1232, and so on. He also wants to find out about the war in 1238, which was fought between the Japanese and the French, and about the kama-kura-shogunate, a political organization formed by the Tokugawa shogunate in 1246.
