Shuya Nanahara (Male Student No. 15, Third Year Class B, Shiroiwa Junior High School, Shiroiwa Town, Kagawa Prefecture) had been staring outside, leaning over Yoshitoki Kuninobu (Male Student No. 7), who had the window seat. As Yoshitoki dug through his bag, Shuya stared at his own right foot, which was sticking out in the aisle, and stretched out his Keds sneakers with his toes. It used to be that Keds weren't hard to find, but now they were extremely rare. The canvas of Shuya's shoes were torn on the right heel, and the stray threads stuck out like cat's whiskers. The shoe company was American, but the shoes themselves were made in Colombia. At present, 1997, the Republic of Greater East Asia hardly suffered from a shortage of goods. In fact it was rich with commodities, but imports were hard to come by lately. Well, it was only to be expected in a country with an official policy of isolationism. Besides, America—both the government and the textbooks called them "the American Imperialists"—was an enemy state.

From the back of the bus, Shuya watched his forty-one classmates, who were illuminated by dull fluorescent lights fixed in dingy ceiling panels. They were all in the same class from last year. They were all still excited and chatting away, since hardly an hour had passed since their departure from their hometown of Shiroiwa. Spending the first night of a study trip on a bus seemed a little cheap. Worse yet, it felt like they were going on a forced march. But everyone would calm down once the bus crossed the Seto Bridge and got on the Sanyo Highway and headed towards their destination, the island of Kyushu.
